Front 7

PreGanglionic Neuron

Back 7

Begins at Cell body of brain or spinal cord Lateral Horn of Grey Matter. Type B fiber

Front 8

PostGanglionic Neuron

Back 8

Cell body lies outside of CNS in an Autonmic ganglion. Unmyelinated Type C fiber that ends at visceral effector

Front 9

Divisions of the ANS

Back 9

Sympathetic (Fight or Flight) -Thoracic and Lumbar segments. Parasympathetic (Rest and Repose)- Preganglionic fibers leaving the brain and sacral segments

Front 10

Sympathetic Pathway

Back 10

Short Preganglionic neuron, to ganglion, longer postganglionic neuron. Uses ACh, N-Ep, and EP

Front 11

Parasympathetic Pathway

Back 11

Longer Preganglionic Neuron, to ganglion which very close or on effector, short postganglionic neuron. Uses only ACh

Front 12

SNS Sensory Input

Back 12

Special Senses and Somatic Senses

Front 13

ANS Sensory Input

Back 13

Mainly from Interoceptors. some from special and somatic senses.

Front 14

SNS Control of Motor Output

Back 14

Voluntary contrl from Cerebral Cortex, with contributions from basal ganglia, cerebellum, brain stem, and spinal cord.

Front 15

ANS Control of Motor Output

Back 15

Involuntary control from limbic system, hypothalamus, brain stem, and spinal cord. Limited control from cerebral cortex

Front 16

SNS Effectors

Back 16

Skeletal Muscle

Front 17

ANS Effectors

Back 17

Smooth muscle, cardiac muscle and glands

Front 18

SNS Responses

Back 18

Contraction of Skeletal Muscle

Front 19

ANS Responses

Back 19

Contraction/relaxation of Smooth and cardiac muscle, secretion of glands.

Front 20

Sympathetic Ganglia

Back 20

Trunk (chain) Ganglia near vertebral bodies. Prevertebral ganglia near large blood vessels in gut

Front 21

Parasympathetic Ganglia

Back 21

Terminal ganglia at wall of organ

Front 22

Autonomic Plexuses

Back 22

Tangled networks of sympathetic and parasympahtetic neurons

Front 23

Sympathetic Effects

Back 23

Increased metabolism, respiratory and heart rate. Decreased digestive. Specialized neurons in adrenal glands

Front 24

Rami Communicantes

Back 24

White - Myel - Preganglionic
Gray - Unmel - Postganglionic

Front 25

Smypathetic Ghain Ganglia

Back 25

(Paravertebral Ganglia) Control effectors in the body wall, head, neck and limbs of thoracic activity

Front 26

Sympathetic Collateral Ganglia

Back 26

(Prevertebral Ganglia) Ganglionic Neurons that innervate tissues and organs in the abdominopelvic cavity

Front 27

Sympathetic Adrenal

Back 27

Release Neurotransmitters into the bloodstream where they act as hormones

Front 28

Spinal Nerve Route

Back 28

Out the same level

Front 29

Smypathetic Chain Route

Back 29

Up chain and out Spinal Nerve

Front 30

Prevertebral Ganglion Route

Back 30

Out Splanchnic nerve to collateral ganglion

Front 31

Structures innervated by Spinal Nerves

Back 31

Sweat Glands, Arrector Pilli, Blood vessels to skin and skeletal

Front 32

Thoracic and Cranial Plexuses supply

Back 32

Heart, lungs, esophagus and thoracic blood vessels

Front 33

Splanchnic Nerves to prevertebral ganglia Supply

Back 33

GI Tract from Stomach to rectum, urinary and Reproductive organs

Front 34

Ventral Root of the Thoracic Spinal Nerve Damage

Back 34

No sypmathetic motor function on the affected side of the head, neck, or trunk

Front 35

Ventral roots of Cervical spinal nerves are damaged

Back 35

Produce voluntary muscle paralysis on the affected side leaving sympathetic funciton intact

Front 36

Preganglionic cell bodies of Parasympathitic NS found in

Back 36
