Question

Which of the following is NOT an effector controlled by the autonomic nervous system cardiac muscle glands skeletal muscle smooth muscle in blood vessels smooth muscle in the digestive system Which of the following statements applies to the autonomic nervous system? the ANS innervates skeletal muscle. ANS functions are consciously controlled. the ANS controls unconscious movement of skeletal muscles. the receptor molecules of the ANS may be muscarinic, nicotinic, or adrenergic. A single neuron from the spinal cord carries action potentials to effector organs in the ANS. A nerve which causes the smooth muscle of a blood vessel wall to constrict, contains neurons. sensory afferent autonomic somatic motor cranial Preganglionic fibers from the thoracic and lumbar segments of the spinal cord are part of division of the ANS. central sympathetic somatic motor parasympathetic: ganglionic Sympathetic stimulation of the postganglionic cells of the adrenal medulla causes the of acetylcholine and epinephrine norepinephrine and acetylcholine. epinephrine and norepinephrine. cortisol. aldosterone.

Explanation / Answer

[16] (c) Skeletal muscles are not controlled by AUtonomic Nervous System. ANS contolls Smooth muscles and cardiac muscles.

[17] (d) The receptor molecules of the ANS must be muscarinic, nicotinic or adrenergic.

[18] (c) A nerve which causes smooth muscle of a blood vessel wall to constrict contains autonomic neurons.

[19] (c) Preganglionic fibers from the thoracic and lumbar segments of the spinal cord are part of sympathetic division of ANS.

[20] (c) Sympathetic stimulation of the postganglionic cells of the adrenal medulla causes the release of epinephrine and norepinephrine.
