Three layers of connective tissue in which the brain and
Meninges
spinal cord are wrapped
Dura Mater Outermost layer of the meninges
Arachnoid Mater Middle layer of the meninges
Pia Mater Innermost layer of the meninges
Which layer of the meninges in immediately deep to the
Dura Mater
inner surface of cranial bone?
Four lobes: Frontal lobe, parietal lobe, occipital lobe, tem-
Lobes of the brain
poral lobe
The lobe at the front of the brain associated with move-

ment, speech, and impulsive behavior.
A region of the cerebral cortex whose functions include
Parietal Lobe
processing information about touch.
A region of the cerebral cortex responsible for hearing and
Temporal Lobe
language.
A region of the cerebral cortex that processes visual infor-
Occipital Lobe
mation
A thick band of axons that connects the two cerebral hemi-
Corpus Callosum
spheres and acts as a communication link between them.
How does the left and right hemispheres of the brain
Corpus Callosum
connect?
The endocrine system's most influential gland. Under the
Pituitary Gland influence of the hypothalamus, the pituitary regulates
growth and controls other endocrine glands.
A brain structure that relays information from the cerebel-
Pons
lum to the rest of the brain

, Part of the brainstem that controls vital life-sustaining
Medulla Oblongata functions such as heartbeat, breathing, blood pressure,
and digestion.
A large structure of the hindbrain that controls fine motor
Cerebellum
skills. (Balance and coordination)
Largest part of the brain; responsible for voluntary mus-
Cerebrum cular activity, vision, speech, taste, hearing, thought, and
memory.
The oldest part and central core of the brain, responsible
Brainstem
for automatic survival functions.
Major control center of the autonomic nervous system
and endocrine system that lies below the thalamus. It di-
rects several maintenance activities (eating, drinking, body
Hypothalamus temperature)
- Essential role in homeostatic regulation of all body sys-
tems.
