incorrect
19.
Is the dura a vascular tissue?
incorrect
20.
How does alcohol or radiation affect the fetal neuroblast cells?
A.
Unipolar, bipolar, multipolar
B.
Highly collagenous outer coat of a nerve. Inelastic and adds protection, streght and support to the fasciculi within. Continuous with the dura mater.
C.
Pcchinonion bodies
D.
The first preganglionic neuron is long and the postganglionic is short. Located both in CNS and PNS. Release of ACH.
E.
Mostly collagen but it does have a few capillaries. It has vessels going around its outer surface.
F.
Small, bilateral sinus. Carries blood along the petrooccipital suture from the cavernous sinus to the lower sigmoid extension of the transverse DVS.
G.
Composed of a phospholipid-cholesterol and neurokeratin (protein) accumulations. Myelin is made by a surrounding cell (not by the neuron)
H.
No! It is an intravasicular oligodendrocyte.
I.
Empties blood into the straight DVS (along with the vein of Galen)
J.
This may cause them to under or over shoot their target sites.
K.
Simple cuboidal
L.
Read it! There will be a question on the exam!
M.
Double layer of visceral dura extending into a few fissures of the brain.
N.
1. Parasympathetic 2. Sympathetic
O.
Runs between equivalent structures on opposite sides of the CNS
P.
Neuroepithelial origins (along the neural tube). Little mitotic activity but undergo growth and maturation. Depend of glial cells to help guide them as the migrate and spread through the CNS.
Q.
Tuffed prolongations of arachnoid mater that herniate into the dura mater and associate with the lining of the dural venous blood sinuses
R.
70 to 80 % in the choroid plexus
S.
1. Get out a blank piece of paper 2. Draw the circle of Willis 3. Label it.
T.
Via the Foramina of Monro (interventricle foramina)
Type the Answer that corresponds to the displayed Question.
incorrect

Type the Question that corresponds to the displayed Answer.
incorrect
22.
The space between the dura and the arachnoid mater
incorrect
23.
1. Perineuronal Satelites (gray mater) 2. interfascicular (white mater)
incorrect
24.
No.. we start loosing our cilia at the time of birth
incorrect
25.
At the junction of the falx cerebri, tentorium cerebelli and the falx cerebelli. Runs in a posterior inferior direction to the confluens sinuum
incorrect
26.
Largest DVS and bilateral. They run along the occipital bone margins of the tentorium cerebelli.
incorrect
27.
The blood vessels to the brain penetrate inward from the pia mater with a slight cuff of pia
incorrect
28.
The coat that wraps arpund groups of fibers. Most elastic of the mesodermal covers and it is continuous with the pia and the arachnoid maters as it approaches CNS structures.
incorrect
29.
Neurons which carries impulses away from the center toward the major peripheral target sites. 1: Visceral 2. Somatic
incorrect
30.
1. Connective tissue-like function 2. Part of the BBB 3. Store (very little) glucose in the CNS 4. Forms a scar like tissue after injury to CNS 5. Are affected by neurotransmitters and maybe even ions (K)
