NS

Question 1

Multipolar

Answer 1

motor neurons + interneurons

Question 2

Pseudo-unipolar

Answer 2

typical sensory

Question 3

Bipolar

Answer 3

special senses

Question 4

Endoneurium

Answer 4

connective tissue surrounding individual nerve fires/ axons

Question 5

Perineurium

Answer 5

Surrounds bundle nerve fibres/vasicle

Question 6

Epineurium

Answer 6

Surrounds entire nerve + associated capillaries

Question 7

Grey matter

Answer 7

neuronal cell bodies + synpases

Question 8

White matter

Answer 8

Myelinated axons

Question 9

CNS

Answer 9

brain + spinal chord. receives interprets and takes action.

Question 10

PNS

Answer 10

cranial + spinal nerves. detects change in environment + responds via innervation muscles and viscera. 43 nerves. 31 spinal. 12 cranial. Axons supported schwann cells.

Question 11

SNS/ANS

Answer 11

SNS = voluntary and conscious. Skeletal, pain. Detects outside body.
ANS= involuntary para and sym. Detects inside body- viscera. Regulated hypothalamus. Cardiac, smooth muscle + glands. 

Cell body pre- synaptic = cns
Cell body post = near target organ

Question 12

Nerves

Answer 12

axons in PNS

Question 13

Tracts

Answer 13

Axons within CNS

Question 14

Nuclei

Answer 14

neuronal cell bodies with CNS grey

Question 15

Ganglia

Answer 15

neuronal cell bodies within PNS

Question 16

Brain

Answer 16

Cerebrum - L + R cerebral hemispheres
Cerebellum
Brain stem

Question 17

Spinal chord

Answer 17

Brainstem to L1/2 below= Cauda equina. After 3rd month fetus spinal chord no longer occupies full length stops L3

Question 18

Spinal nerves

Answer 18

31 pairs
8 cervical
12 thoracic
(cervical + brachial plexus)
5 lumbar
5 sacral
(lumbosacral plexus)
1 coccygeal

Mixed nerves. Motor neurons (multipolar) cell bodies CNS ventral.
Sensory neurons (pseudo) DRG

Question 19

Poorly localized pain- nausea

Answer 19

Visceral afferent of sympathetic system

Question 20

Where do presynpatic sympathetic nerves arise from

Answer 20

Lateral horn of spinal chord grey matter T1-L2

Question 21

Where are post synaptic ganglia located on the sympathetic division.

Answer 21

Paravertebral ganglia - sympathetic chain

Prevertebral - close to target organ

Question 22

Sympathetic division controls

Answer 22

Fight or flight
Vaso constriction
Sweat glands ( rest glandular is para)

Question 23

Where do presynpatic para sympathetic nerves arise from

Answer 23

Brainstem

S2-S4 sacral segments spinal chord

Question 24

Where do presynpatic para sympathetic nerves exit the CNS from

Answer 24

Cranial nerves 3,7,9,10

Pelvic splanchnic nerves S2-S4

Question 25

Where are post synaptic ganglia for parasym located

Answer 25

walls target organ
