Vocab Chapter 7 #2 Flashcards
the largest part of the brain; consists of right and left cerebral hemispheres
cerebrum
an outward fold of the surface of the cerebral cortex
gyri
a groove or cleft, the deepest depression or inward folds on the brain
fissures
outer gray matter of the cerebrum
cerebral cortex
area of the cerebral cortex responsible for interpreting impulses from cutaneous sense organs and proprioceptors located in the post-central gyrus
primary somatic sensory area
pertaining to the area at the back of the head
occipital lobe
front of the head, location of auditory area
temporal lobe
area of the cerebral cortex responsible for voluntary movement; located in the precentral gyrus
primary motor area
a specialized cortical area that is very involved in our ability to speak
Broca’s area
areas involved in higher intellectual reasoning and socially acceptable behavior
Anterior association area
encompasses part of the posterior cortex
Posterior association area
allows for sound or words
Speech area
that part of the forebrain between the cerebral hemispheres and the midbrain including the thalamus, the third ventricle, and the hypothalamus; also called the interbrain
Diencephalon
a mass of gray matter in the diencephalon of the brain
thalamus
the region of the diencephalon forming the floor of the third ventricle of the brain
Hypothalamus
roof of the third ventricle; composed of the pineal gland and the choroid plexus of the third ventricle
Epithalamus
The portion of the brain consisting of the medulla, pons, and midbrain
brain stem
part of the brain stem containing reflex centers for vision and hearing and fiber tracts (cerebral peduncles) that convery ascending and descending impulses
midbrain
most inferior part of brain stem; involved in visceral control
medulla oblongata
a special group of reticular formation neurons; play a role in consciousnesses and the awake/sleep cycle
Reticular activating system
part of the hindbrain, involved in producing smoothly coordinated skeletal muscle activity
cerebellum
reflex centers involved in olfaction (sense of smell) bulge from the floor of the hypothalamus posterior to the pituitary gland
Mamillary bodies
part of the epithalamus, relates to endocrine system
Pineal gland
the membranes that cover the brain and spinal cord
Meninges
the outermost and toughest of the three membranes (meninges) covering the brain and spinal cord
Dura mater
middle layer of the meninges; has web-like extensions attach to the inner layer, the pia mater
Arachnoid mater
innermost meningeal layer; clings to the surface of the brain and spinal cord
Pia Mater
the fluid produced by choroid plexuses; fills the ventricles and surrounds the Central Nervous System
Cerebrospinal fluid
separate neurons from Bloodborne substances; composed of the least permeable capillaries in the whole body
Blood Brain Barrier
brain injury with reversible ddamage
concussion
