|
central Nervous sysytem
|
consist of the brain, cerebrum, diencephalon, pituitary gland, brain stem and cerebellum
|
|
|
|
cerebrum
|
functionis for higher brain functions suchas reasonin, sensory perception, emotions, willed, movements, memory and conciousness as well as controlling learned behavior
|
covers and surrounds the thalamuslargest and uppermost division 2 halves right and left hemisphere
|
|
|
2 hemispheres of cerebrum
|
cerebral cortex and an inner cerebral medulla
|
|
|
|
cerebral medulla
|
function is to conduct nerve impulses to andfrom differentarea of the nervous system
|
inner portion of cerebrum composed of myelinated axons contains the basal ganglia aka extra pyramidal system ; injury or destruction of basl ganglia may result in motor disorders(parkinson's and hunington disease)
|
|
|
Cerebral Cortex
|
function is to control body activities sucha as voluntary movement vision hearing and speech and itellectual abilities
|
outer portion of cerebrum contains cell body of neurons aka gray matter
|
|
|
EEG electroencephlagram
|
recording of electrical activity of cortex(brain)
|
|
|
|
cerebellum
|
coordinate muscular movements and posture as well as help maintain balance
|
lies behind brain stem and below the cerebrum butterfly shaped structure which is divided into hemispheres where each hemisphere is encased surrounding a cortex
|
|
|
diencephalon
|
contains thalamus and hypothalamus loocated superior to medulla oblongata
|
|
|
|
Thalamus
|
relays impulses from sensory organs to the brain and associates those sensations as pleasant or impleasant
|
locted in center mass of brain
|
|
|
hypothalamus
|
regulates the pituitary glands ;controls involuntary bodily process such as metabolism, water& electrolye balance and body temp appetite thirst pleasure
|
|
|
|
pituitary gland
|
regulates function of many other endocrine gands which produce and secrete hormones into the blood or lymph nodes
|
located in center brain and attached to hypothalamus
|
|
|
master gland
|
pituitary gland named b/c it controls nearly all major body functions secreting hormones and relaying nerve impulse
|
|
|
|
Brain stem
|
controls many of the body functions that are not under concious control including, heartbeat breathing and blood pressure
|
runs continuos with spinal cord and extends up to the cerebrum; the relay between the brain and spinal cord
|
|
|
vital system
|
brain stem
|
|
|
|
3 divisions of brain stem
|
midbrain pons and medulla
|
midbrain and pons located just superiorto medulla oblongata
|
|
|
medulla oblongata
|
injury could result in death; controls respiration, heart rate, dilation and constriction of blood vessels and vomitting
|
most inferior portion of brain stem above spinal cord
|
|
|
cerebrospinal fluid
|
acts as cushion and brings nutrients to the brain and spinal cord; removes waste from spinal system
|
|
