1

Where are the cell bodies located for visceral afferent nerves

Posterior root ganglia or relevant cranial nerve ganglion

2

The central processes (axons) enter cord through whaat

The posterior root or specific cranial nerve

3

What do peripheral processes (dendrites) carry

Impulses from viscera to cell bodies of autonomic ganglia, plexus, somatic nerves without synapse

4

Sympathetic afferents travel through what to spinal ganglia

Through the sympathetic trunk by passing through white ramus communicans (for spinal ganglia)

5

What travels in sacral spinal nerves and cranial nerves

Parasympathetic afferents

6

Visceral afferents are associated with receptors that are sensitive to what

Pressure, chemical concentrations, and muscle stretching

7

Pregang parasymp fibers are what kind

Cholinergic

8

What are the pregang parasymp fibers

CN 3, 7, 9, 10 and spinal nerves 2, 3, 4

9

Where do postgang parasymp fibers extend to

Effector organs

10

Post gang parasymp fibers extend to effector organs to do what 4 things

Decrease CO, constrict bronchial tree, constrict pupils, stimulate peristalsis

11

What parasymp fibers will supply structures in the head

CN 3, 7, 9

12

What parasympathetic will supply cardiac, respiratory, digestive structrues in neck, thorax, abdomen

CN X - vagus

13

What parasympathetics supply the distal parts of the digestive system and urogential system

S 2,3,4

14

Where are the preganglionic cell bodies located at for the oculomotor nerve

The oculomotor nucleus within the midbrain periaquaductal gray

15

Where does the oculomotor nerve synapse when going into the orbit

The ciliary ganglion then to the eye

16

Where are postgang axons for the oculomotor nerve carried in

Ciliary nerves that enter eyeball

17

What muscles do postgang axons of the oculomotor nerve supply after being carried to the eye

The ciliary muscle and the sphincter pupillae

18

Pregang cell bodies of the facial nerve are located where

In the superior salivary nucleus

19

Where does the facial nerve exit the CNS

In the intermediate nerve carried in two branches, greater petrosal and chorda tympani

20

Where does the greater petrosal nerve leave the facial nerve

At the geniculate ganglion carrying pregang parasymp fibers

21

After reentering in the temporal bone through the foramen lacerum where does the greater petrosal nerve go

Travels in pterygoid canal to synapse in pterygopalatine ganglion

22

Postgang fibers of the greater petrosal nerve are distributed in the lacrimal to where

The lacrimal, nasal, palatine, and pharyngeal glands

23

Where does the chorda tympani carrying pregang parasymp fibers leave the temporal bone

The pterygotympanic fissure

24

After leaving the temporal bone what does the chorda tympani combine with

The lingual nerve (mandibular division trigeminal)

25

The pregang fibers of the chorda tympani leave the lingual to reach where

The submandibular ganglion

26

Postgang fibers of the chorda tympani travel to where

The submandibular and sublingual glands (also recieve parasymp info from submandibular gland)

27

Where are pregang cell bodies located for the glossopharyngeal nerve

The inferior salivary nucleus

28

The pregang parasymp fibers of the glossopharyngeal pass through the tympanic plexus and reform as the what

Lesser petrosal nerve

29

Postgang parasymp fibers from the glossopharyngeal go from otic ganglion and carried to where

Parotid and posterior lingual glands

30

How do postgang parasymp fibers of the glossopharyngeal nerve reach the parotid gland

Via the auriculotemporal nerve
