Terms in this set (32)

arachnoid mater
middle layer of the meninges
arbor vitae
white matter of the cerebellum
tree of life
brain stem parts
midbrain, pons, medulla oblongata
Cerebellum
A large structure of the hindbrain that controls fine motor skills, balance and coordination
corpus callosum
a broad band of nerve fibers joining the two hemispheres of the brain.
Diencephalon
Contains thalamus and hypothalamus
dura mater
thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord
fornix
arch of neural tissue that separates the lateral ventricles from the third ventricle
frontal lobe
The lobe at the front of the brain associated with movement, speech, and impulsive behavior.
hemisphere
one half of the brain
Hippocampus
A neural center located in the limbic system that helps process explicit memories for storage.
Hypothalamus
a neural structure lying below the thalamus; directs eating, drinking, body temperature; helps govern the endocrine system via the pituitary gland, and is linked to emotion
Medulla
the base of the brainstem; controls heartbeat and breathing
Meninges
three protective membranes that surround the brain and spinal cord
Midbrain
A small part of the brain above the pons that integrates sensory information and relays it upward.
occipital lobe
A region of the cerebral cortex that processes visual information
olfactory bulb
the brain center for smell, located below the frontal lobes
optic chiasm
point at which optic nerve fibers cross in the brain
parietal lobe
portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position
pia mater
thin, delicate inner membrane of the meninges
pineal gland
secretes melatonin
Pons
A brain structure that relays information from the cerebellum to the rest of the brain
spinal cord
a major part of the central nervous system which conducts sensory and motor nerve impulses to and from the brain
temporal lobe
A region of the cerebral cortex responsible for hearing and language.
Thalamus
whitthe brain's sensory control center, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
white matter
myelinated axons
gray matter
unmyelinated neural tissue
gyrus (gyri)
ridges
Sulci (sulcus)
shallow grooves
ventricles of the brain
canals in the brain that contain CSF
Cerebrum
largest part of the brain
fissure
deep groove in the brain
