- brainstem

- spinal cord

Which division of the ANS functions to maintain homeostasis during times of stress?

sympathetic

The subdivisions of the autonomic nervous system are the _______ division and sympathetic division

parasympathetic

The preganglionic neurons of the parasympathetic division originate in the ______.

brainstem

lateral gray matter of S2-S4

Somatic and autonomic are divisions of the ______ nervous system.

motor

The sympathetic division of the ANS is also called the ______ division.

thoracolumbar

Autonomic nervous system functions are regulated by the hypothalamus, which controls autonomic nervous system regions in the ______.

brainstem and spinal cord

During times of relaxation, the ______ division of the autonomic nervous system utilizes discrete and localized innervation, stimulating only one or a few structures at the same time.

parasympathetic

Where do the preganglionic neurons of the sympathetic division originate in the CNS?

lateral horns of T1-L2

The ______ division of the autonomic nervous system is also called the craniosacral division because of the location of its preganglionic neurons.

parasympathetic

Which of the following works constantly with the somatic nervous system to regulate body organs and maintain normal internal functions?

autonomic nervous system

Which cranial nerves are associated with the parasympathetic division of the autonomic nervous system?

- facial (CN VII)

- vagus (CN X)

- oculomotor (CN III)

The location of preganglionic neurons in the parasympathetic division of the autonomic nervous system allows it to be also known as the ______ division.

craniosacral

Parasympathetic innervation to the ciliary muscle results in ______ ______, which makes the lens more rounded to allow for close vision.

lens accommodation

Which autonomic ganglion provides postganglionic axons to the lacrimal glands and small glands of the nasal cavity, oral cavity, and palate?

pterygopalatine ganglion

Parasympathetic innervation of which muscles results in lens accommodation?

CILIARY MUSCLE

The ganglion that supplies postganglionic parasympathetic innervation to the submandibular and sublingual salivary glands to increase their secretions is the ganglion.

submandibular

Parasympathetic innervation from the postganglionic axons of the pterygopalatine ganglion causes the lacrimal glands and small glands of the nasal cavity, oral cavity, and palate to ______.

increase secretion

Which gland receives parasympathetic innervation from the glossopharyngeal nerve (CN IX)?

parotid salivary gland

The otic ganglion receives parasympathetic axons from which cranial nerve?

glossopharyngeal (CN IX)

Which division of the autonomic nervous system exhibits a mass activation response during stressful situations, stimulating all innervated components at once?

sympathetic division

The vagus nerve innervates the

ovaries and testes

Postganglionic axons from which autonomic ganglion supply the submandibular and sublingual salivary glands in the floor of the mouth?

submandibular ganglion

The salivary gland that receives parasympathetic innervation from the glossopharyngeal nerve (CN IX) is the _____ salivary gland.

parotid

The preganglionic neuron cell bodies of the S2-S4 spinal cord segments are the origin of preganglionic parasympathetic axons that branch to form the ______.

pelvic splanchnic nerves

Preganglionic sympathetic axons travel within the spinal nerves numbered ______ to ______.

T!; L2

Which autonomic ganglion, located anterior to the ear, receives parasympathetic axons from the glossopharyngeal nerve (CN IX)?

otic ganglion

Which cranial nerve supplies parasympathetic innervation to the thoracic organs, most abdominal organs, and the gonads?

vagus nerve (CN X)

A sympathetic trunk looks like a pearl necklace, with bundles of axons making up the "string" and sympathetic trunk making up the "pearls".

ganglia

The ganglion that supplies postganglionic parasympathetic innervation to the submandibular and sublingual salivary glands to increase their secretions is the _______.

submandibular

The pelvic splanchnic nerves originate from the neuron cell bodies housed within the lateral gray matter of the ______ spinal cord segments.

S2 to S4
