What is the name of the neurotransmitter that enters the synaptic cleft during the excitation phase of skeletal muscle contraction?

True or False: Dendrites and cell bodies can generate an action potential.

During digestion of food, the smooth muscle in your digestive organs contract in a unique way to create rhythmic waves that push food particles through the GI tract. What is this called?

The iliopsoas is created by the union of two distinct muscles with different origins but the same insertion. What are these two muscles?

Which of the following is the correct term for the extracellular matrix (ECM) of a muscle fiber?

True or False: Groups of cell bodies located within the PNS are called ganglia.
