Question 8

Answer 8

protoplasmic astrocytes- found chiefly in the gray matter. These glial cells have numerous, short, branching cytoplasmic processes

Question 9

Answer 9

fibrous astrocytes or “Spider cells” have fewer processes than protoplasmic astrocytes but also have perivascular feet. More common in inner core of the brain in white matter

Question 10

Answer 10

oligodendrocytes found in both the gray and white matter

Question 11

Answer 11

microglia- occur in white and gray matter and are active phagocytes

Question 12

Answer 12

Question 13

Answer 13

Question 14

Answer 14

DH = dorsal horn

VH = ventral horn

Question 15

Answer 15

N = nucleus of ventral horn cell

Np = neuropil

Question 16

Answer 16

N = nucleus of ventral horn cell

NB = Nissl bodies

NN = neuroglial cells

Question 17

Answer 17

NF = nerve fibers

CB = cell bodies of dorsal root ganglion

CT= connective tissue

Question 18

Answer 18

A = axon

NL= nucleoli

N = nuclei

Sat C = Satellite cells

from dorsal root ganglion

Question 19

Answer 19

Peripheral nerve

P = perineurium

S = schwann cells

A = axons

Question 20

Answer 20

myelinated nerve

A = axon

epi = epineurium

• white line separating slide in half is perineurium
• connective tissue between myelinated axons is endonerium

Answer 24

pacinian corpuscle (senses pressure and vibration)

Question 25

Answer 25

Meissner’s corpuscle- sensitive to tap and flutter (light touch)

Question 26

Answer 26

I = intrafusal fibers

OC and IC are connective tissue capsule

Purple slide is extrafusal muscle

B = nuclear bag fiber

C = nuclear chain fiber

Answer 30

Mol = molecular layer

Gr = granular layer

WM = white matter

Pia mater of cerebellum

Question 31

Answer 31

purkinje cell layer

g= granule cells

BC = basket cells (in molecular layer)

Question 32

Answer 32

C = cornea

L = lens

I = iris

CS = canal of schlemm

CB = ciliary body

Question 33
