Which layer of the meninges in immediately deep to the inner surface of cranial bone? -
ANS Dura Mater
Lobes of the brain - ANS Four lobes: Frontal lobe, parietal lobe, occipital lobe, temporal lobe
Frontal Lobe - ANS The lobe at the front of the brain associated with movement, speech, and

, Temporal Lobe - ANS A region of the cerebral cortex responsible for hearing and language.
Occipital Lobe - ANS A region of the cerebral cortex that processes visual information
Corpus Callosum - ANS A thick band of axons that connects the two cerebral hemispheres
and acts as a communication link between them.
How does the left and right hemispheres of the brain connect? - ANS Corpus Callosum
Pituitary Gland - ANS The endocrine system's most influential gland. Under the influence of
the hypothalamus, the pituitary regulates growth and controls other endocrine glands.
Pons - ANS A brain structure that relays information from the cerebellum to the rest of the
brain
Medulla Oblongata - ANS Part of the brainstem that controls vital life-sustaining functions
such as heartbeat, breathing, blood pressure, and digestion.
Cerebellum - ANS A large structure of the hindbrain that controls fine motor skills. (Balance
and coordination)
Cerebrum - ANS Largest part of the brain; responsible for voluntary muscular activity, vision,
speech, taste, hearing, thought, and memory.
Brainstem - ANS The oldest part and central core of the brain, responsible for automatic
survival functions.
Hypothalamus - ANS Major control center of the autonomic nervous system and endocrine
system that lies below the thalamus. It directs several maintenance activities (eating, drinking,
body temperature)
