centralnervoussystemolareawadjouogoundele
Cerebrum
lobes
:-1
Frontal
lobe:plan and initiate voluntary movements, -2
Parietal
lobe: awareness of general somatic sensation, -3
Temporal
lobe: language comprehension, -4
Occipital
lobe: location of visual cortex
type of gyri
1- precentral gyrus : control motor cortex, 2- postcentral gyrus: controls the motorsensory cortex
areas
: 1-
Broca
area : control the movement ofspeech , 2-
wernicke
area: control the comprehension of language
three white matter tracts
: 1-
Association
tract: connect same hemisphere, 2-
Commissural
tract : connect one hemisphere to another, 3-
Projection
tract : connect one hemisphere from the peripheral descending
Diencephalon
Thalamus
: controls our motor movements
Hypothalamus
controls our visceral movements
Epithalamus
constutue of pineal gland that secrete melatonin that controls out sleep
Brain stem
midbrain
contain the peduncles
Pons
connect the cerebellum to the cerebral cortex
Medulla oblongata
controls the hypothalamus ,and involved in automatic behavior
Spinal cord
conus medullaris
: cone pf the spinal cord , and located in the first and second lumbar vertebrae
Cauda Equina
: end of the vertebrae canal
Filum terminale
: end of the filament , which attaches to the coccyx inferiorly
Anterior roots
extension of the spinal cord from the anterior part
Posterior roots
: extension of the spinal cord form the dorsal, and surround the ganglion
CNS protection
meninges
1- dura mater: next to the bone, 2- arachnoid : composed of the subarachnoid space, 3- pia matter : very vascular filled with cappillary
subarachnoid space
: space filled with spinal fluid , and blood verssels
Epidural space
: space filled with adipose tissues
Dural sinuses
: space filled with oxygen poor blood.
Cerebellum
:smooth ,and coordinate body movements.
three parts of cerebellar peduncles
Superior peduncles
: connect the midbrain to the cerebellum
Inferior peduncles
: connect the medulla oblongata to the cerebellum
Middle peduncles
: connect the pons to the cerebellum
