Flashcards in Lecture 1 Deck (22):
1

What are the 4 parts of the CNS?

Brain
Brainstem
Spinal cord
Retina

2

Assign dorsal/ventral for the brain and spinal cord.

Brain:
Dorsal = top 1/2; ventral = bottom 1/2 (towards feet)

Spinal cord:
Dorsal = back; ventral = belly

3

What is the difference between para and midsagittal?

Midsagittal = sagittal cut down the mid-line
Parasagittal = all other sagittal cuts

4

What is a nerve cell body in the CNS vs PNS?

CNS = neuron
PNS = ganglion cell

5

What is a collection of neuron cell bodies in the CNS vs PNS?

CNS = nucleus
PNS = ganglion

6

What is a bundle of nerve fibers in the CNS vs PNS?

CNS = tract
PNS = nerve

7

What is a fasciculus? Vs funiculus?

FAS = A bundle
FUN = cord

8

What is a lemniscus?

A ribbon

9

What is a commisure? And a decussation?

COM = bundle fibers crossing the mid-line
DEC = point where tract cross the mid-line

10

What is ipsilateral vs contralateral?

IPS = same side of the midline
CONTRA = opposite side of the midline

11

What is afferent vs efferent?

Afferet = into a structure
Efferent = away from

12

What are the 4 structures that make up the lateral ventricle?

Frontal/anterior horn
Central part
Temporal/inferior horn
Occipital/posterior horn

13

What are the 4 lobes of the brain?

Frontal
Parietal (top)
Occipital (back)
Temporal (below)

14

Which 3 sulci define the boundaries of the lobes of the brain?

Central sulcus (pre and post central)
Lateral sulcus
Parieto-occipital sulcus

15

What 2 structures lie within the sylvian fissure?

Insula = hidden gyri
Opercula

16

Where is white and gray matter in the brain vs spinal cord?

Brain
White = inside & gray = outside

Spinal cord is opposite

17

Where is the primary motor cortex?

Pre-central gyrus

18

Where is the primary somato-sensory cortex?

Post-central gyrus

19

Where is the primary auditory cortex?

Temporal lobe - Sylvian fissue

20

Where is the primary visual cortex?

Occipital lobe

21

What kind of cortex makes up the bulk of cerebral hemispheres?

Association - coordinates both sides of the brain

22

What is the cellular arrangement of the cortex?

6 layers of cells
Varying width and cellular density depending on which cortex of the brain you sample
