Brain

Question 1

Cerebral cortex

Answer 1

2 mm sheet with 6 cell laminae. Gyri most outer and sulci most inner. Really deep ar fissures

Question 2

Corpus callosum

Answer 2

Connects two hemispheres

Question 3

Brodmann areas

Answer 3

50 different areas defined in terms of function

Question 4

Frontal lobe

Answer 4

Separated from parietal lobe by the central sulcus, with the motor cortex in precentral gyrus in front of it and the sensory cortex behind it

Question 5

Temporal lobe

Answer 5

Separated from frontal lobe by lateral or sylvian fissure. Conserned with auditory info, high order visual, object and categorisation.

Question 6

Insular cortex

Answer 6

Underneath frontal and temporal lobes and concerned with autonomic functions, motivation and emotional states

Question 7

Parietal lobe

Answer 7

Located behind central sulcus and above lateral fissure. Contains somatosensory cortex which is part of the postcentral gyrus. Involved with sensory info

Question 8

Occipital lobe

Answer 8

Separated from the parietal lobe by fine line from the perieto-occipital sulcus to the pre-occipital notch. Concerned with initial processing of visual info

Question 9

Olfactory tracts

Answer 9

Located in the frontal lobe, arise from olfactory bulbs. Receive info from the nerve in the nasal cavity

Question 10

Parahippocampal gyrus

Answer 10

Located in temporal lobe, covers the hippocampus which is involved with memory.
