Q

The cerebral cortex is located superficially and consists of

A

cortical grey matter (i.e. nerve cell bodies) that is highly convoluted to form a complex pattern of ridges (gyri; singular, gyrus) and furrows (sulci; singular, sulcus)

Q

The lateral fissure:

A

Separates the temporal lope from the frontal and parietal lobes

19
Q

What is found deep to the lateral fissure

A

The insula

20
Q

The parts of the frontal, parietal and temporal lobes overlying the insula

A

= the operculum

21
Q

A single, uninterrupted sulcus that extends from the medial longitudinal fissure (superiorly) to the lateral fissure (inferiorly)

A

= central sulcus

22
Q

The central sulcus also extends (for a very short distance) onto the medial surface of the hemispheres – within the longitudinal fissure

A
23
Q

What is found within the precentral gyrus

A

Primary motor region of the cortex

24
Q

What is found in the postcentral gyrus

A

primary somatosensory cortex

25
Q

Intraparietal sulcus divides the parietal lobe into

A

a superior and inferior parietal lobule

26
Q

What is located within the superior temporal gyrus

A

The primary auditory cortex

Q
A
28
Q

Location of the primary visual cortex

A

Calcarine sulcus

29
Q

Cingulate sulcus course and location

A

curves around the corpus callosum and runs parallel to it

It passes posteriorly and inferiorly around the posterior surface of splenium of the corpus callosum, it then becomes continuous with the parahippocampal gyrus

30
Q

Parahippocampal sulcus location

A

lies deep to the parahippocampal gyrus within the temporal lobe

31
Q

The parahippocampal sulcus is formed by

A

the in-curling of the inferior medial part of the temporal lobe

32
Q

A

Cingulate gyrus
parahippocampal gyrus
hippocampus
