Q

What does the cerebrum have?

A

The cerebrum has convolutions (gyri) and
these are separated by fissures (sulci) of
varying depth (increase surface area)

Q

What does the white matter consist of?

A

The white matter consists of nerve fibres which
transmit impulses to and from the cortical nerve
cells and from one cortical area to another

bounded superiorly by the
parieto-occipital sulcus and inferior by
the calcarine sulcus

22
Q

MEDIAL SURFACE - OCCIPITAL LOBE _ The lingual gyrus :

28
Q

The H-shaped sulcus divides the inferior surface of the cerebrum into :
