Electrical Mechanical Coupling (a) Use the ventral corticospinal
pathway to describe the motor signal travels from the CNS to the
biceps brachii. (b) Define a motor unit (c) Describe the process of
the NT release from a somatic neuron (d) Describe the step by step
process of excitation contraction relaxation for a skeletal muscle
cell (starts with NT binds with the receptor on a skeletal muscle
cell)
