Question 2

Ventricles definition

Answer 2

Interconnected, hollow cavities that house cerebrospinal fluid

Question 3

Choroid Plexus definition

Answer 3

Structure that produces CSF and releases it into the ventricle system

Question 4

Lateral ventricles

Answer 4

In the cerebral hemisphere, separated by the very thin septum pellucidum

Question 5

Third Ventricle

Answer 5

Surrounded by the thalamus

Question 6

Fourth ventricle

Answer 6

Surrounded by the pons and cerebellum

Question 7

Order of scalp-brain layers

Answer 7

Scalp, skull, dura mater, arachnoid mater, subarachnoid space, pia mater, cerebral cortex.

Question 8

Purpose of cerebrum folds?

Answer 8

Increases surface area for neural activity to support and expansive network of synapses

Question 9

Sulcus (pl sulci) definition

Answer 9

Valley or groove separating large parts of the brain

Question 10

Gyrus

Answer 10

Ridge of fold within a lobe

Question 11

Frontal lobe:

Answer 11

“In the front”. Primary motor cortex.

Question 12

Temporal lobe

Answer 12

“By your temples” primary auditory cortex (audio processing), primary olfactory cortex (smell processing)

Question 13

Parietal lobe

Answer 13

“Parents pat top of head” primary somatosensory cortex and gustatory cortex (Taste)

Question 14

Precentral gyrus

Answer 14

Primary motor cortex, the line/gyrus bordering the side of the central sulcus closer to your eyes

Question 14

Postcentral gyrus

Answer 14

Primary somatosensory cortex. After central sulcus.

Question 14

Occipital

Answer 14

“Eyes on back of head” primary visual cortex

Question 14

Answer 14

Connects right and left sides of the brain

Question 15

Projection tracts

Answer 15

Connects higher and lower regions of the central nervous system

Question 16

Association tracts

Answer 16

Connects one part of the cortex to adjacent regions in the same hemisphere
