Q

If it is “Adrenergic,” it is a(n) __?__
A. Sympathetic end organ receptor, either alpha or beta
B. ACh receptors, which may be in the CNS or PNS. In the PNS, they are in the somatic NMJ and in ANS ganglion

D. Connection point between the somatic motor neuron and the skeletal muscle. The somatic neuron releases ACh, which diffuses across junction (gap) and binds to the receptor on skeletal muscle. This triggers the opening of an ion channel, which depolarizes the skeletal muscle and results in muscle contraction.
