Document Summary
Recognize the importance of connexins in cardiac muscle. Distinguish between presynaptic and postsynaptic cells in a chemical synapse. Know which cells (pre or postsynaptic) have neurotransmitter (nt)-containing vesicles. Uncoupling protein on the mitochondrial membrane that leads to the leaking of proteins. This protein is also known as thermogenin because it can generate heat without generating. After exposed to neurotoxin, a nerve conduction velocity test was carried out to ensure there isn"t long lasting nerve damage. The factors that determine the speed of an action potential are both axon diameter and myelination. Nerve action has a lot of important factors that can change electrical potential across its plasma membrane which can allow cells to exchange messages or coordinate activity with other cells. It all can start with mitochondria which generates sufficient energy to power channels. Cells in the body interact with one another, communicating via chemicals, electrical signals or touch. Cells are bound together via adjacent plasma membranes.
