Answer 1

Dips/grooves in the brain

Question 2

What are Gyrus?

Answer 2

Elevations of the brain

Question 3

What are Fissures

Answer 3

Deep grove: seperating the two hemispheres of brain.

Question 4

What are the ventricles?

Answer 4

Cavitys within each region of the brain containing CSF.

Question 5

What is the arrangment of White and Grey Matter in the Brain?

Answer 5

Grey matter on surface
White matter inside (Basal ganglia/nuclei–> collection of neural bodies within the white matter and is grey matter itself)

Question 6

Answer 6

Median longitudinal Fissure

Question 7

What is the Corpus callosum

Answer 7

Connects the right and left cerebral hemispheres

Question 8

Lateral sulcus

Answer 8

Seperates the temporal lobe to the frontal lobe

Question 9

Central Sulcus

Answer 9

Runs from the lateral sulcus superiorly to the middle of the brain.

Question 10

How are the Parietal and the occipital lobe seperated

Answer 10

Parieto-occipital sulcus: found on the medial surface of the cerebral hemisphere

Question 11

What are the Gyrus either side of the central sulcus called

Answer 11

Precentral Gyrus and Post central gyrus

Question 12

What Sulcus and Gyrus is found on the medial surface of the hemisphere

Answer 12

Cingulate sulcus and the cingulate gyrus which is directly inferior to the sulcus
They also run parallel to the corpus callosum

Question 13

Where is the hippocampus Found

Answer 13

on the medial surface of the temporal lobe, and is an inturned/curled in portion of the lobe.
