brain locations
Brain stem:midbrain
-relays ascending senroy impulse and descending motor impulses
-reflex center for visual activity and startle reflex
Brainstem:pons
-relays ascending sensory impulses and desending motor impulses
-has vital centres to assist in control of breathing
Brainstem: Medulla oblongata
-contains vital centeres
-cardiovascular centre(regulates rate and force of heartbeat and blood pressure)
-respiratory centres( controls rate and depth of breathing)
none vital centres
.vomitting
.coughing
Brainstem: Reticular activating system
-Scattered through brainstem to reach cerebral cortex
-Maintains consciousness and controls sleep/wake cycle
Diencephalon: Thalamus
relay station for sensory impulse from brain stem into the cerebral cortex
Diencephalon:Hypothalamus
-Regulates homeostasis
-control ANS
-Regulates body temperature
Diencephalon: Epithalamus
Contains the pineal gland which produces melatonin to induce sleep
Cerebellum: Cerebellum
-Regulates posture and balance
-Helps to co-ordinate complex squences of skeletal muscles contraction
Cerebrum: Cerebrum
-Conscious thought,memory logic,interpretation of sensory information
initiation of voluntary movement
Cerebrum:Limbic system
-A ring of structures which includes the hypothalamus
-controls emotional responces,memory processing
Cerebrum:ventricles
4 cavities(2 lateral,a 3rd & 4th) each contain a choroid plexus that forms CSF
Cerebrum: Basal nuclei
ajust and refine outgoing movements
Cerebrum:Cerebral Cortex
stores memories
Cerebrum: Corpus Callosum
Where 2 hemispheres are linked
