Meneges
(3) layers of fibrous membranesthat cover the brain and spinal cord
Ventricle
Cavity or chamber;

one of the two chambers of the heart;

on of the four chambers in the brain in which cerebrospinal fluid is produced

ventricular
Gyrus
raised area of the cerebral cortex;

pleural - gyri
Cerebrum
largest part of the brain

composed of (2) cerebral hemispheres
Cerebellum
small section of the brain located under the cerebral hemispheres

functions in coordination, balance and muscle tone
Stroke
damage to the brain due to lack of oxygen

usually cause by a blood clot in the vessel (thrombus) or rupture in the vessel

cerebrovascular accident (CVA)
Thalmus
region of the brain located in the diencephelon

chief relay center for the sensory impulses traveling to the cerebral
Hypothalmus
region of the brain that controls the pitutary and maintains homeostasis
Succulus
shallow groove;

between the convulsions of the cerebral cortex
Cerebro Spinal Fluid (CSF)
fluid that circulates in and around the brain and spinal cord
aphasia
loss or defect in language communication

effective ephasia - loss of ability to speak or write

receptive ephasia - loss of
understanding of written or spoken language is
Midbrain
upper portion of the brainstem
Hematoma
tumor or swelling filled with blood
Brain Stem
portion of the brain that connects the cerebrum with the spinal cord;

contains the midbrain, pons, and medulla oblongata
Medulla oblongata
part of the brain stem that connects the brain to the spinal cord
Electroencephalograph (EEG)
an intrument used to study electrical activity of the brain

Electroencephalogram - the record made
Cerebral Cortex
a very thin outer layer of gray matter on the surface of the cerebral hamispheres
Pons
the area of the brain between the midbrain and the medulla

connects the cerebellum to the CNS
Diencephalon
area of the brain between the cerebral hemispheres and the midbrain

contains the thalmus, hypothalmus and the pitutary gland
Concussin
injury resulting from a violent blow or shock
Cerebrum
the largest part of the brain

divided into hemispheres (left/right) and lobes
Cerebrum is divided into:
right and left cerebral hemispheres

by the longitudinal fissure
Brain Stem:
Midbrain (superior)
Pons (inferior to the midbrain)
Medulla (inferior to the pons)
Cerebellum means:
little brain
Dura matter is the:
thickest, toughest and outermost layer of the meninges
Matter means:
mother
referring to the protective function
Dura:
hard
Meninges has (3) layers:
Dura mater (outermost)
Arachnoid mater (middle)
Pia mater (innermost)
Arachnoid mater is the:
loosely attached to the deepest of the meniges by weblike fibers

allows space for movement of CSF between layers
Pia mater is the:
innermost layer

attached to the nercous tissue of the brain/spinal cord
Lingitudinal fissure separates:
the left and right hemispheres of the brain (cerebrum)
Scull layers from the skin down:
1. skin
2. periosteum
3. skull
4. dura mater
5. arachnoid
6. pia mater (4-6 meninges)
7. gray matter
8. white matter (7-8 brain
tissue)
Corpus collosum
where the right brain says hello the left brain
Gyri
cortex folds
sulci
shallow grooves separating the gyri (cortex folds)
Frontal lobe:
primary motor area (control of skeletal area)
Parietal lobe:
Primary sensory area

Interprets:
- touch,
- pain,
- temperature

Estimates:
- distances
- size
- shapes
Temporal lobe:
Auditory area
- receiving/interpreting
impulses from the ear

Olfactory area:
- sense of smell
Occipital lobe:
Visual receiving/association area
- interprets impulses from
the eye (retina)
Communication areas:
Auditory receiving area

Auditory association area

Speech comphehension area (Wernicke area)

Motor Areas:
Motor speech area (Broca area)

Visual areas
Auditory receiving area:
detects sound impulses transmitted from the environment
Auditory association area:
interprets the sounds
Speech comprehension area
speech recognition and meaning of words
Motor areas:
spoken/written communication
Motor speech area (Broca area)
Speech muscles: tongue, soft palate and larynx are controlled here
Visual areas:
recieves visual immages and interprets them as words

the ability to read/understand is in this area



occipital cortex
Memory:
the mental faculty for recalling ideas
Medulla/pons controls:
the heart
Medulla oblongata controls:
- respiratory center
(muscles of respiration)
- cardiac center (rate/force
of heartbeat)
- vasomotor center (regulates contractions of smooth muscle)
(controls blood flow and blood pressure)
Contralateral control:
opposite side control
CEREBELLUM
- coordinates voluntary muscles
- maintain balance (standing,walking,sitting)
- maintains muscle tone (for quick response to change)
