Flashcards in cerebral cortex Deck (35):
1

convolutions

gyri

2

depressions

sulci

3

separates frontal from parietal

central sulcus (fissure of Rolando)

4

separates temporal from frontal

lateral sulcus

5

divides the brain into two hemispheres

median longitudinal fissure

6

between cuneus and precuneus

parieto occipital fissure

7

the parieto occipital fissure is between

cuneus and precuneus

8

divides occipital lobe into cuneus and lingual

calcarine fissure

9

the surface area of the cerebral cortex is increased by

convolutions

10

the cerebral cortex develops from the

pallium

11

2 divisions of pallium

paleo-/archipallium
neopallium

12

the neopallium is located b/n

hippocampus and the paleopallium

13

the paleopallium is located

lateral to the corpus striatum

14

the motor cortex contains a large amount of

pyramidal cells

15

sensory cortex is characterized by

granular cells

16

nerve cells of the cerebral cortex

1. pyramidal cells
2. stellate cells
3. fusiform cells
4. horizontal cells of cajal
5. cells of martinotti

17

large fusiform cells =

modified pyramidal cells

18

smll multipolar cells present throughout the levels of the cortex

cells of martinotti

19

layers of the cerebral cortex

molecular
external granular
external pyramidal
internal granular
internal pyramidal
multiform layer

20

most superficial layer

molecular layer (plexiform layer)

21

the molecular layer is located where

below the pia mater

22

the external layer contains large number of

small pyramidal cells and stellate cells

23

the external pyramidal layer is composed of pyramidal cells whose cell body size

increases from the superficial to the deeper borders of the layer

24

this layer is composed of closely packed stellate cells

internal granular layer

25

the internal granular layer is composed of

closely packed stellate cells

26

the internal granular layer has a high conc of horizontally arranged fibers known as

External band of baillarger

27

myelinated fibers of this layer form the ________

internal granular; stripe of Gennari

28

the internal pyramidal layer gives rise to

corticospinal, corticobulbar, corticostriatal

29

giant pyramidal cells in the motor cortex of the precentral gyrus

Betz cells

30

the internal pyramidal layer contains a large number of horizontally arranged fibers that form the

internal band of Baillarger

31

different types of cortex based on number of layers

neocortex
allocortex

32

aka isocortex or homogenetic cortex

neocortex

33

the allocortex includes

paleocortex
archicortex

34

paleocortex includes

olfactory cortex

35

archicortex includes

hippocampus and dentate gyrus
