Q

Where is the medulla and what is it’s function?

A

myelencephalon
Function: breathing, blood pressure, and respiration (location for many CN)

17
Q

What is gray matter made of?

A

mostly cell bodies and dendrites
(gray hair= cell head and “hair”)

18
Q

What is white matter made of?

A

mostly axons

19
Q

Spinal nerves overview

A

arise from spinal cord
innervate structures caudal to the head
cell bodies located in dorsal root ganglia or ventral horn
all neurons are mixed (sensory and motor)

dorsal and ventral roots connect with the spinal cord

nerve splits into a dorsal and ventral branch

20
Q

Where do the dorsal branch of spinal nerves connect to?

A

the muscles, skin of the back

21
Q

Where do the ventral branch of spinal nerves connect to?

A

ventral body wall, limbs, visceral organs

22
Q

Cell bodies for sensory neurons are in the __________ and connect to the _____ of the spinal cord

A

dorsal root ganglia, dorsal horn

23
Q

Each spinal nerve innervate a strip of skin called a _______ (pinch a dog)

A

dermatone

24
Q

Cell bodies for motor neurons are in the __________ and connect to the _____ of the spinal cord

A

ventral root ganglia, ventral horn

(spinal nerve branches combine to innervate specific muscles)
