This unit lab is a model of a moving human limb with muscles, tendons, bones, and joints built from "play-doh". Each picture of my model has a description of what units that are involved in order to create movement. I also have models of a Neuron that shows: Axon with Schwann cells, Action Potential, and the propagation of action potential along the axon. Once again, each model is labeled accordingly. Lastly, there is a model of a muscle cell that includes: Sacolemma, T-tuble, Sarcomere, Sarcoplasmic reticulum, and myosin.
Below is an extra model representing action potential.
These models represent how our muscles receive information from the cns and in return, take that information and turn it into a reaction, or stimulation. This lab showed me just how complex are muscle system is. Through afferent and efferent transmission of stimulation, we are able to receive stimulation (or sensation) transmit the information, process, and then create a reaction. This lab was a positive re-enforcement of unit 3.
