17
Q

Gyri

A

elevated ridges of tissue (hills)

18
Q

Sulci

A

shallow grooves (valleys)

19
Q

Fissures

A

DEEP grooves that separate parts of the brain

20
Q

Longitudinal fissure

A

divides the cerebral hemispheres sagitally

21
Q

Corpus callosum

A
  • white fiber tract
  • highway for impulses, connects the left and right side of the brain
22
Q

Precentral gyrus

A

before the central sulcus, in the frontal lobe

23
Q

Postcentral gyrus

A

after the central sulcus, in the parietal lobe

23
Q

Central sulcus

A

acts as the dividing line between the frontal and parietal lobe

24
Q

Corticospinal tract

A

collection of axons that carry movement related info from the cerebral cortex to the spinal cord

25
Q

Basal nuclei

A
  • islands of gray matter w/i the white matter
  • regulates voluntary motor movement
26
Q

White matter

A

deeper layer of the cerebrum, clusters of axons: tracts

27
Q

Gray Matter

A

outermost surface of the cerebrum, clusters of cell bodies: nuclei

28
Q

Diencephalon

A
  • contains the: epithalamus, thalamus, hypothalamus
29
Q

What structure is within the epithalamus? What does it do?

A
  • Choroid plexus
  • knots of capillaries, form cerebrospinal fluid
30
Q

What does the thalamus do? Where is it located?

A
  • relay station for sensory impulses going to the sensory cortex
  • diencephalon
31
Q

What does the hypothalamus do? Where is it located?

A
  • 4F: fighting, fleeing, feeding, fornicating –> basic biological needs
  • diencephalon
32
Q

Limbic System

A

an emotional control center consisting of the amygdala, hippocampus, hypothalamus

33
Q

Brainstem

A

consists of the midbrain, pons, and medulla

34
Q

What does the cerebral aqueduct do? Where is it located?

A
  • canal that connects the third and fourth ventricles
  • midbrain
35
Q

What do the cerebral peduncles do? Where are they found?

A
  • convey ascending and descending impulses
  • midbrain
36
Q

What do the corpora quadrigemina do? Where are they found?

A
  • reflex centers involved in vision and hearing
  • midbrain
37
Q

What does the pons do? Where is it located?

A
  • breathing rhythm/control
  • brain stem
38
Q

What does the medulla oblongata do? Where is it found?

A
  • regulates vital activities: heart rate, blood pressure, breathing, swallowing, vomiting
  • brainstem
39
Q

Cerebellum

A
  • controls balance
  • maintains smooth, coordinate skeletal movements
