Name 1 possible consequence of damage to the epiphyseal plate in Tom's L) femur and outline why this occurs. blanchecoad https://padlet.com/blanchecoad/786ddm32athx/wish/352220979 In most cases of type 11 fractures to the growth plate, the epiphysis separates from the metaphysics on an angle which causes a tear in the periosteum. These injures are commonly reduced but the torn periosteum can get trapped in the fracture site and prevent the full reduction to occur. If this ccurs, an operation may be needed to realign the fracture and growth plate. Failure to do so may leave the bone deformed or disturb growth by the injury developing a bony bar and subsequent growth arrest (The Royal Children's Hospital Melbourne).]]> 2019-04-17 07:37:29 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/352220979 Tom is a 15 year old soccer player that fell over during training. An X-ray revealed a Type II fracture of the L) proximal femoral growth plate. It required closed reduction and plaster cast immobilisation to heal. blanchecoad https://padlet.com/blanchecoad/786ddm32athx/wish/352221075 2019-04-17 07:38:20 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/352221075 Q3. Name (in the correct order) & briefly outline (include cells) the phases of bone fracture repair. kel_morley https://padlet.com/blanchecoad/786ddm32athx/wish/352416225 Bone fracture repair is a slow procedure. It occurs in four stages.
Phase 1- Reactive Blood vessels in the bone and Periosteum are torn, this causes a blood clot to accumulate at the site of  the damage. The bone cells die off, inflammation occurs, osteoclasts and phagocytes dispose of impaired tissue.
Phase 2a- Reparative
Fibrocartilaginous callus  forms and new blood vessels are created. Fibroblasts create collagen fibres, chondroblasts deliver fibrocartilage, soft callus attaches across the fracture.
Phase 2b- Reparative
Bony callus forms, osteoprogenitor cells evolve into osteoblasts, spongy bone trabeculae is formed, hard callus is produced.
Phase 3 - Remodelling
Osteoclasts resorb deceased fragment portions, spongy bone is replaced by compact bone, fracture is healed (Marieb & Hoehn, 2010). ]]> 2019-04-17 19:38:01 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/352416225 Q4. Name and describe at least one event that occurs during each period of a muscle twitch. kel_morley https://padlet.com/blanchecoad/786ddm32athx/wish/352446790 Three stages occur in a twitch contraction.
Stage 1 -  Latent period
Nerve stimulus occurs via a  motor neuron firing and Ach is released.
Calcium is released.
Stage 2 - Contraction period
Ach binds to receptors that open sodium ion channels. Calcium binds to troponin, the myosin binding site is revealed and the shortening of the sarcomere occurs.
Stage 3- Relaxation period
Active transport takes place. calcium  goes back to the sarcoplasmic reticulum.
Process begins again on demand
(Marieb & Hoehn, 2010).

Three factors that influence the growth and repair of Tom's bones during his teenage years. gkpatman1 https://padlet.com/blanchecoad/786ddm32athx/wish/352890430 1. Minerals - an adequate dietary intake of calcium and phosphorous are required while bones are healing. Small amounts of magnesium, fluoride and manganese are also necessary for bone remodelling.
2. Vitamins - good levels of vitamin A is required to stimulate the activity of the osteoblasts to build new bone. A good level of vitamin C is needed for the synthesis of the main bone protein collagen.
3. Hormones - very important for bone growth, activating the osteoblasts and helping with cell division at the epiphyseal plate. Hormones also contribute to the synthesis of the proteins required to build new bone (Torora & Derrickson, 2012).]]> 2019-04-21 01:56:53 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/352890430 Group Rules kel_morley https://padlet.com/blanchecoad/786ddm32athx/wish/354366531

Identify which muscle fibre type is best suited for this activity and provide rationale for the answer. blanchecoad https://padlet.com/blanchecoad/786ddm32athx/wish/354808215 Participants in a powerlifting competition perform 1 Repetition Maximum, 1RM, therefore their maximum muscle contraction may only last up to 6 seconds (Weightlifting, 2019).
Fast glycolytic fibres are activated for this movement. Fast twitch B fibres primary action is used in rapid and fast speed contraction. Creatine phosphate is the first source of energy for this contraction (Tortora et al., 2019).]]> 2019-04-28 19:31:02 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/354808215 Q2. The process by which the muscle fibre produces the adenosine triphosphate (ATP) required to contract the muscles used during a bench press. gkpatman1 https://padlet.com/blanchecoad/786ddm32athx/wish/357990013 The Fast-Glycolytic muscle fibres produce the adenosine triphosphate (ATP) energy required to contract the muscle using the Anaerobic Glycolysis process.
- First the process takes glycogen which is stored along with glucose from the blood.
- The process of glycolysis breaks down the glucose to create two molecules of ATP and two molecules of Pyruvic acid.
- The Pyruvic acid is then converted to lactic acid which is released into the blood stream.
This process provides energy for muscles to contract for approximately two minutes (Tortora & Derrickson, 2012).]]> 2019-05-08 11:36:52 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/357990013 gkpatman1 https://padlet.com/blanchecoad/786ddm32athx/wish/357993863 2019-05-08 11:51:59 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/357993863 gkpatman1 https://padlet.com/blanchecoad/786ddm32athx/wish/357995426 2019-05-08 11:57:52 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/357995426 blanchecoad https://padlet.com/blanchecoad/786ddm32athx/wish/358759318 Chat Room]]> 2019-05-10 06:29:57 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/358759318 Q5. Name and describe each of the contractions in relation to muscle and length. blanchecoad https://padlet.com/blanchecoad/786ddm32athx/wish/359163368 When Ben performs a bench press the first action is the lowering of the bar to his chest. This is called the Eccentric phase.  This occurs when the load is greater than the force that the muscle can generate. In this contraction the muscles lengthen and the angle at the joint increases. Phase two is the concentric phase. This occurs in the pushing action, when the muscle is pushing against gravity or the load.  In this contraction the muscles shorten and the angle at the joint is decreased (Powerlifting Australia, 2019).]]> 2019-05-12 02:24:39 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/359163368 When waking up one morning, seventy year old Maria noted that she could not move her fingers to button up her blouse with her R) hand. She tried to talk to her daughter however despite being able to speak, she could not arrange the words in a coherent fashion. She sought medical assistance and was diagnosed as having a stroke. kel_morley https://padlet.com/blanchecoad/786ddm32athx/wish/359755165 2019-05-14 05:19:46 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/359755165 Q1. State which major part of the brain has been damaged and name two major functional areas of that part of the brain that have been affected. kel_morley https://padlet.com/blanchecoad/786ddm32athx/wish/359756022 The cerebrum is damaged.  The association area called Wernicke's area located in the left temporal and parietal lobe. It is responsible for the arrangement of coherent speech. 
The motor area called the primary motor area found in the frontal lobe is also affected. It controls voluntary action of skeletal muscles (Tortora et al., 2014).]]> 2019-05-14 05:26:55 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/359756022 Q2. Samantha's blood sugar levels are high. Describe the negative feedback regulation of the hormone involved in hyperglycaemia. kel_morley https://padlet.com/blanchecoad/786ddm32athx/wish/359772583 Hyperglycemia stimulates the  hypothalamus to release a hormone called growth hormone inhibiting hormone (GHIH) and suppresses the release of  growth hormone -releasing hormone (GHRH).
GHIH travel through the portal blood system into the anterior pituitary and inhibits the release of human growth hormone (HGH). Insulinlike growth factors (IGFs) and small levels of HGH slow the breakdown of glycogen that occurs in the liver and glucose is slowly secreted into the blood. Blood glucose levels return to normal (Tortora et al., 2014).]]> 2019-05-14 06:56:01 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/359772583 Q3. Samantha has commenced pharmaceuticals as a treatment for her prediabetes. After taking the medication for a few weeks she experiences a hypoglycaemic episode where her blood glucose level falls below the recommended level. Describe the negative feedback regulation of the hormone involved in hypoglycaemia. blanchecoad https://padlet.com/blanchecoad/786ddm32athx/wish/360144749 When the body becomes hypoglycaemic it releases a hormone called epinephrine. This hormone is released from the adrenal glands in order to stimulate the release of more glucose into the blood. However, if this is unsuccessful and blood sugar drops to dangerous levels, the adrenal glands will release cortisol. The pancreas will release glucagon and the pituitary gland will release growth hormone (Brutsaert, E.F 2019). In Samantha's case the recommendations from Brutsaerts  (2019) would be to cease taking the medication. Samantha's blood glucose should be recorded over time to determine if the medication is the cause. ]]> 2019-05-15 00:23:31 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/360144749 Q5. The axons of the neuron identified above extend from the brain via two pathways. Which specific pathway (within either one or the other of these pathways) is affected? Using this pathway as an example, explain why damage to the L) side of Maria's brain has affected the movements in Maria's R) hand. kel_morley https://padlet.com/blanchecoad/786ddm32athx/wish/364838827 The direct motor pathway, specifically the Lateral Corticospinal, is affected. The left side of Maria's brain sends somatic sensory signals from the cerebrum.These signals descend and cross over to the right side in  the Pyramids of the Medulla Oblongata. They continue to descend into the spinal cord through the Lateral Corticospinal tract and into the Lower Motor Neuron, which then conveys the nerve impulses that control the muscles on the right side of  Maria's body (Tortora et al., 2014).]]> 2019-05-31 07:24:55 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/364838827 Samantha (50 years old) has a family history of diabetes type 2, is morbidly obese and suffers from high blood pressure. At a routine medical visit, it was recommended that she make an appointment for diabetes screening. Her initial glucose levels indicated the presence of higher than normal blood glucose levels. kel_morley https://padlet.com/blanchecoad/786ddm32athx/wish/365021642 2019-06-01 08:01:45 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/365021642 Q3. Can neurogenesis occur to replace damaged/destroyed neurons in the central nervous system (CNS)? gkpatman1 https://padlet.com/blanchecoad/786ddm32athx/wish/366059140 Neurogenesis is the generating of new neurons formed in the brain.  Neurogenesis has little or no effect on damaged or destroyed neurons within the CNS. The first factor that inhibits this process is the blocking influences from neuroglia especially the oligodendrocytes. The second factor is the missing growth stimulating signals that were in attendance during fetal development. Axons in the CNS are myelinated by oligodendrocytes and myelin is one of the factors stopping the regenerating of neurons (Tortora & Derrickson, 2012).]]> 2019-06-06 09:47:50 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/366059140 Q4 Hormones within the body (other than those identified in 2 & 3 above) can contribute to an elevation in blood glucose. Choose one hormone and describe the mechanism by which it raises blood sugar levels. gkpatman1 https://padlet.com/blanchecoad/786ddm32athx/wish/366072332 When blood sugar levels are too low (hypoglycemia) encourages alpha cells from the pancreas to secrete the hormone glucagon. Glucagon acts on the liver cells (hepatocytes) to  increase the rate of conversions of glycogen into glucose.  Glucose is then released into the blood stream at a rapid rate promoting the rise in blood levels. If the blood levels rise too high (hyperglycemia) this then stops the release of the hormone glucagon

State the fatigue resistance of the previously identified muscle fibre and describe 2 factors that may contribute to a metabolic fatigue specifically when powerlifting. https://padlet.com/blanchecoad/786ddm32athx/wish/367651508 Fast glycolytic fatigue is caused by a series of event within the body. Firstly there is an insufficient amount of acetylcholine is released from the motor neurons, which causes a depletion of creatine phosphate, leading to an inhibited release of calcium from the sarcoplasmic reticulum, resulting in a lack of oxygen or glycogen within the muscle. Lactic acid and ADP contribute to metabolic fatigue which stops an athlete from perform their maximum lift in a powerlifting competition
(Hargreaves, 2019).]]> 2019-06-14 19:41:58 UTC https://padlet.com/blanchecoad/786ddm32athx/wish/367651508 Q4. The damage to Maria’s brain has resulted in her inability to move her R) arm. Which specific neuron in the neural circuits that make up the somatic motor pathways has been affected in this case? Give a rationale for the answer. charlene_suchting https://padlet.com/blanchecoad/786ddm32athx/wish/367668948 The interneurons in the cerebral cortex are damaged and not stimulating the upper motor neuron in Maria’s case which is not synapsing with a lower motor neuron in the central nervous system in order to contract the skeletal muscle and has resulted in her inability to move her right arm (Tortora & Derrickson, 2019).
