Flashcards in Meninges/layers covering brain &v surface structures of brain Deck (11):
1

Dura Matter:

Tough, opaque outer layer covering the brain & spinal cord

outermost/1st CT layer

2

Arochnoid Matter:

2nd layer/middle layer of CT covering brain/spinal cord

3

Pia Matter:

3rd layer/inner most CT covering brain/spinal cord

thin,clear layer

4

Cerebrum:

front/anterior portion of brain
largest/most prominent strucutre of brain
uppermost region of CNS

Contains hippocampus, olfactory bulb, basal ganglia

2 cerebrum hemispheres L & R cerebrum hemispheres

5

Longitudinal Fissure:

seperates L & R cerebrum hemispheres

6

Frontal Lobe:

anterior end of cerebrum

7

Parietal Lobe:

posterior to the frontal lobe

8

Temporal Lobe:

along lateral aspect of EACH hemisphere

9

Occipital lobe:

posterior tip of cerebrum

10

Insula Lobe:

is a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal and frontal lobes).

11

Cerebellum:

posterior to the cerebrum
seperated from the cerebrum by the "transverse fissure"

divided into 2 cerebellar hemispheres
