Question 1

The reverse omega sign to tell which lobe is frontal and which is partietal lobe

Central sulcus

Question 2

White mater is the myelinated neurons

Question 3

Gyri is the bumpy out bits

Question 4

Where the white mater joins is your corpus collosum

Question 5

The dark parts at the side is the start of the lateral ventricles

The third ventricle comes into view later on in-between the lateral ventricles

Question 6

Fourth ventricles is by the cerebellum and the pons

Question 7

CSF is made in lateral ventricles

Question 8

Hydrocephalus if anything is blocked

Question 9

Thalamus below the levels of the lateral ventricles

Question 10

Occuipal lobe is same level of the thalamus

Question 11

Sylvian fissure same level of the thalamus
The temporal lobe starts here

Question 12

Midbrain is visible when the start of the cerebellum is

Question 13

Pons is visible when fourth ventricle is

Question 14

Midbrain - pons -medulla -spina cord

Cerebellum - fourth ventricle

Foramen magnum

Question 15

Optic nerve optic chiasam

Question 16

Pituitary gland - pituitary stock - behind the optic chiasam

Hypothalamus

Question 17

Pituitary gland sits in the sella turcica
