Exam 18: Autonomic Nervous System

The second neuron in an autonomic pathway is called a _________ neuron.

The preganglionic axons of CN VII extend to the

Paravertebral and prevertebral ganglia are part of the parasympathetic branch of the ANS.

The ANS uses pathways that include two-neuron chains to innervate its effector organs.

Both types of axons of the sympathetic branch of the ANS use norepinephrine as the neurotransmitter.

Which cranial nerves are associated with the parasympathetic division of the ANS? A: III B: IV C: V D: VII E: IX F: X G: XII

Which is not an effector innervated by the autonomic nervous system?

The parasympathetic innervation from the pelvic splanchnic nerves is responsible for erection of the female clitoris and the male penis.

Which type of innervation causes reduced blood flow to the digestive tract?

All ANS preganglionic axons release _____________ as their neurotransmitter.

The parasympathetic postganglionic axons of the sacral spinal nerves innervate the A: Large intestine B: Reproductive organs C: Salivary glands D: Pupillary constrictor muscles E: Urinary bladder F: Ureters

During its embryological development,the autonomic nervous system forms from

Which type of innervation causes pupil dilation?

Parasympathetic postganglionic axons from the otic ganglion cause an increase in secretion from the parotid salivary glands.

Which statements are correct concerning the sympathetic division of the ANS? A: Preganglionic neuron cell bodies are located in the lateral horns of the T1-L2 regions. B: Preganglionic neuron cell bodies are located in brainstem nuclei. C: It is associated with the oculomotor and facial nerves. D: It participates in the "fight-or-flight" response. E: Preganglionic neuron cell bodies are located in the sacral region of the spinal cord.

The parasympathetic preganglionic axons of CN VII exit from the

Except for the _______ region of the spinal cord,one sympathetic trunk ganglion is approximately associated with each spinal nerve.

The _______ division of the ANS dominates when an individual relaxes after a large meal.

Which type of innervation causes the heart rate to increase?

The __________ division of the ANS is most commonly associated with the preparation of the body for emergencies.
