SPINAL CORD MODEL (copy)

1

posterior funiculus, white matter: carries sensory information from spinal cord to brain

2

lateral funiculus, white matter: carries sensory information to brain and motor information from brain

3

anterior funiculus, white matter: carries motor information from brain to spinal cord

5

posterior horn, cell bodies involved in reflexes

6

lateral horn, contain motor neuron cell bodies involved in autonomic functions

7

anterior horn, cell bodies involved in reflexes

8

gray commissure, allows communication between two sides of gray matter

9

central canal, carries CSF through spinal cord

10

posterior median sulcus, divides spinal cord into two posterior sections

12

posterior lateral sulcus, area where dorsal portion of spinal nerves enter the spinal cord

13

anterior lateral sulcus, area where anterior portion of spinal nerves exit the spinal cord

14

anterior median fissure, divides spinal cord into two anterior sections

23

dorsal root, carries sensory information from peripheral receptors to spinal cord

24

dorsal root ganglion, houses sensory cell bodies

25

ventral root, carries motor information from spinal cord to muscles

26

spinal nerve, carries sensory information into spinal cord and motor information out to muscles/glands

27 (on top of 29 + 30)

dorsal ramus of spinal nerve, innervate back and skin of back

28

ventral ramus, innervate anterior body structures not found in thorax or abdominal region

29

gray ramus communicantes, sends sympathetic fibers to effectors

30

white ramus communicantes, brings sympathetic fibers to ganglia
