Describe the process of synaptic transmission. Begin by describing how the action potential occurs. End by describing the binding of the neurotransmitter to receptors. Describe Muscarinic vs. Nicotinic Receptors. (a) What are the types of receptors? (b) Describe their functions. ...
Briefly describe the events of contraction cycling. Sliding Filament Theory: Sliding Filament Theory provides a mechanism for musle contraction. Through a process known as contraction cycling, actin filaments in the muscle cell slide past one another, causing the cell to "contract" or shorten in len...
This signal transmission guides the body to perform essential body functions.Answer and Explanation: Action potentials occur when there is a rapid rise and fall of the membrane potential of a particular cell. Action potentials are usually fast,......
The sinoatrial (SA) node is located at the top, right-hand side of the heart, and it consists of a collection of nerve cells. The SA node is responsible for generating the electrical impulses that cause the muscles of the atria to contract. The atria...
When the cell membrane of a neuron changes its permeability, allowing more positively charged neurons to flow into the cell and other ions flow out, the neuron has reached its: a) action potential. b) quiet potential. c...
