Autonomics

Front 1

Divisions of PNS

Back 1

A. Sensory
1. Somatic
2. Visceral
B. Motor
1. Somatic
2. Autonomic
a. Sympathetic (fight or flight)
b. Parasympathetic (rest and digest)

Front 2

Route of Somatic Receptor Neurons

AFFERANT

Back 2

1. Sensation
2. Through Dorsal Ramus
3. Through Dorsal Root
a. Dorsal Root Ganglia (location of cell bodies)
4. Stop in Gray Matter of Dorsal Horn

Front 3

Route of Somatic Motor Neurons


EFFERENT

Back 3

1. Leave Ventral Horn
2. Go through Ventral Root
3. Connect up with Somatic Sensory Neurons at Spinal Nerve
4. Leave through Ventral Ramus
5. Connects to smooth muscle

Front 4

Autonomic Sympathetic Neuron route to Outer Tube Locations

Back 4

1. Pre-Synaptic or Pre-Ganglionic Neuron body lies in CNS.
2. Synapse
3. Post-synaptic or Postganglonic Neuron is in PNS
4. T1 --> L2

Front 5

Sympathetic Motor Neuron Pathway to Outer Tube

Back 5

1. Leaves Lateral Horn
2. Travels through Ventral root
3 Enters into Ventral Ramus
4. Exits Ventral Ramus
*5. Synapses with Post Ganglionic Neurons.
*6. If in T1 -->L2 the effector is near by, post-ganglionic neurons enter into gray ramus and out through ventral or dorsal ramus
7* If effector is superior or inferior to T1 or L2, pre Ganglonic neuron enters into Sympathetic chain ganglia (paravertabral ganglion) and synapses in another gray ramus. Postganglionic neuron leaves thru ventral or dorsal ramus.

Front 6

Sympathetic Motor Neuron Effectors of "outer tube"

Back 6

1. Sweat Glands
2. Erector Pili
3. Arteries

Front 7

Autonomic Sympathetic Pathway to the Inner Tube Effectors and Location

Back 7

1. Heart and Lungs
2. Diaphragm and digestive system
3. Location of synapse is close to Effector

Front 8

Autonomic Sympathetic Neuron to Inner Tube

Back 8

1. Leave Lateral Horn
2. Pre-Ganglionic passes through Ventral Root
3. Enter White Ramus (on medial side of donut)
4*. T1 -->T5 Pre-ganglionic neuron synapsis with Post-ganglionic similar to outer neuron
5* In T6 Pre-ganglonic neuron leaves and travels to effector. (Splanchnic Nerve). Synapses on effect to post-ganglia effecter. (space is: pre-vertebral ganglia)

Front 9

Splanchnic Nerve

Back 9

Never of the sympathetic Pathway to diaphram and digestive system

Front 10

Autonomic Parasympathetic Nervous System Location

Back 10

1. Long Preganglionic. Body lies in CNS, axon stretches into PNS.
2. Short post ganglionic
