Question

The following questions are true or false:

1.)Negative feedback in the autonomic nervous system requires an afferent signal.

2.)The parasympathetic nervous system innervates the external sphincter of the bladder.

3.)Referred pain is caused by convergence of somatic and autonomic information within the Nucleus of the Solitary Tract.

4.)Inhibition of the sympathetic nervous system inhibits urination primarily by inhibiting the detrusor muscle.

5.)The hypothalamus can directly control preganglionic sympathetic neurons.

1.True.

Information travels along afferent pathway to the control center .

2. True.

The PNS system communicates with the bladder via pelvic nerve.

3.True.

Referred pain is balance between visceral and somatic inputs. The autonomic system afferents in the nerve synapse in solitary nucleus.

4.True

The bladder is composed of intercalated smooth muscle cells called detrusor muscle cells.They are stimulated by sympathetic component of ANS.

5 . False.

The hypothalamus can control sympathetic output via connections to spinal cord .
