Final Project by jenn.barr https://padlet.com/jbarrera7/gyoaerfo49h3 Cockroach Lab en-us 2017-12-13 16:35:55 UTC 2024-05-27 13:44:03 UTC hello@padlet.com Homeostasis Imbalance jbarrera7 https://padlet.com/jbarrera7/gyoaerfo49h3/wish/216221102 This can lead to disease. 
Possible imbalances are...
- High temperature
- Low/high blood oxygen
- Lack of nutrients

When anesthetizing the roach in cold water, this could potentially cause an internal temperature imbalance or oxygen imbalance. ]]> 2017-12-14 16:25:47 UTC https://padlet.com/jbarrera7/gyoaerfo49h3/wish/216221102 Homeostasis jbarrera7 https://padlet.com/jbarrera7/gyoaerfo49h3/wish/216224519 Maintaining homeostasis depends on feedback systems.
- This is a cycle of events in which the status of body condition is continuously monitored and evaluated.
Roach maintains homeostasis by...
1. The receptor is going to detect a change (Ex: the leg being cut off).
2.  The message is going to be sent to the control center.
3. The effector is going to reinforce the stimulus (Ex: the leg will grow back).]]> 2017-12-14 16:32:18 UTC https://padlet.com/jbarrera7/gyoaerfo49h3/wish/216224519 Anatomy jbarrera7 https://padlet.com/jbarrera7/gyoaerfo49h3/wish/216718617 2017-12-16 22:45:00 UTC https://padlet.com/jbarrera7/gyoaerfo49h3/wish/216718617 Lab Setup jbarrera7 https://padlet.com/jbarrera7/gyoaerfo49h3/wish/216720312 2017-12-16 23:38:07 UTC https://padlet.com/jbarrera7/gyoaerfo49h3/wish/216720312 Hierarchy jbarrera7 https://padlet.com/jbarrera7/gyoaerfo49h3/wish/217005357 The six levels:
1.Chemical 
The cockroach has atoms (molecules) throughout it’s body.
2.  Cellular
Cells are the basic unit of life. The roach has cells of all types and sizes.
3. Tissue
The roach has tissues throughout the body.  Muscle and nervous tissues are present throughout binding it’s body and protecting its’ organs.

The roach’s leg would be the organ that we used in this lab.
5. Organ System
The roach has has organ systems that can help it reach Action Potentials.  Example: Nervous System responds to stimuli.  Dendrites extend long enough to send signals when necessary.
6. Organism
The organism that was used in this lab was the roach!

These are all essential to live a functional life. Using the roach as a model is a lot more convenient than using a human organ. Unlike humans, roaches have the ability to grow an organ (their leg) back after it being amputated. Within the leg we are able to see the electrical impulse caused by the neurons in the leg!]]> 2017-12-18 16:56:27 UTC https://padlet.com/jbarrera7/gyoaerfo49h3/wish/217020085 Electrical Impulse jbarrera7 https://padlet.com/jbarrera7/gyoaerfo49h3/wish/217391795 Here we can see the electrical impulses that are being caused by the neurons.
