Muscle system article

Hello lovely people,

I did some research and this was one of the very few articles I found relating to the topic in the muscle system topic. Let me know if you guys think this will do as being the primary source for that specific part of the ebook xx

Q4. Outline the role Sodium plays in the production of a muscle action potential.

Sodium plays a pivotal role in the production of the muscle action potential in a specific method. That is, once the sodium channels open up, the membrane is depolarised in the motor end-plate triggering the action potential on the muscle fiber membrane (sarcolemma). That is, as the concentration of sodium in the extracellular solution is reduced, the action potentials become smaller allowing the Na+ to flow into the muscle cell in order to commence the initiation of the muscle action potential.

Q5. Which specific somatosensory pathway is affected when an individual with MS experiences the loss of the sensations identified in question 4?

Name two (2) specific areas in the cerebral cortex that may be affected when experiencing loss of vibrational sensation and proprioception and provide rationale for answer.

Proprioception and vibration sensation, both carried by the dorsal columns, are frequently impaired in an individual diagnosed with MS. Moreover, this periphery somatosensory pathway (sensory receptors) is impacted when an individual with MS experiences the loss of sensations eg inability to detect various stimuli: thermoreceptors, mechanoreceptors. In these cases, damage to the postcentral gyrus of the parietal lobe, dorsal columns (or, the dorsal root ganglion) can cause the loss of vibrational sensation and proprioception mainly as MS disturbs the ability of nerves to purposefully conduct information.

Q1. Name the two (2) thyroid hormones affected by the above disease and identify the cells that produce them.

The two hormones are Tetraiodothyronine (aka thyroxine) or simply, T4: and, triiodothyronine, known as T3. The cells that produce them are: Follicular Cells (produces T3, T4) and the Parafollicular Cells (produce/secrete calcitonin aka, thyrocalcitonin).
