Last Minute Study

Front 1

4 Things that can cause destruction of the BBB:

Back 1

-Trauma
-Ischemia
-Meningitis
-Inflammation

Front 2

5 results of BBB breakdown:

Back 2

-Seizures
-Hypertension
-Hypercapnia
-Cerebral vasodilation
-Capillary distention

Front 3

Major differences between CSF and plasma:

Back 3

CSF has much more Cl and H+
Plasma has much more protein and amino acids

Front 4

2 types of Brain Edema:

Back 4

-Cytotoxic (intracellular)

-Vasogenic (extracellular)

Front 5

Cytotoxic edema:
-Problem with what?
-Result?

Back 5

Problem w/ Na/K ATPase
-Electrolytes in cell increase
-Water accumulates in cells
-Swelling injures cells

Front 6

Vasogenic edema:
-Problem with what?
-Result?

Back 6

Endothelial cells of capillaries - increased permeability; fluid accumulates along white matter tracts but leaves gray matter alone.

Front 7

Define edema:

Back 7

increases water in brain

Front 8

Define hydrocephalus:

Back 8

increased CSF pressure in brain

Front 9

What feeds the internal capsule?

Back 9

Anterior - lenticulostriates from MCA and ACA

Posterior - Anterior choroidal

Front 10

How do spinal nerves exit the spinal column?

Back 10

Via intervertebral foramen

Front 11

2 types of motor nerves in the spinal cord:

Back 11

-alpha

-gamma

Front 12

alpha neurons innervate

Back 12

extrafusal muscles

Front 13

gamma neurons innervate:

Back 13

intrafusal muscles

Front 14

nucleus where NE is produced:

Back 14

locus ceruleus

Front 15

nucleus where dopamine is produced:

Back 15

substantia nigra

Front 16

nucleus where serotonin is produced:

Back 16

dorsal raphe nucleus

Front 17

midbrain internal contents:

Back 17

-tectum
-Cerebral Peduncle containing:
-tegmentum
-cerebral aqueduct
-crus cerebri
-substantia nigra

Front 18

Tegmentum composed of:

Back 18

-CN 3/4 nuclei
-Red nucleus
-Reticular formation
tracts that aren't crus cerebri

Front 19

Type of axons on cooling receptors

Back 19

Adelta

Front 20

Type of axons on warming receptors

Back 20
