Central nervous system (CNS)
-Consists of the brain and the spinal cord
-Responsible for control of cognitive function &: Both voluntary & involuntary actions
Peripheral nervous system (PNS) includes:
-Cranial nerves & spinal nerves
•They work together to receive an impulse, interpret it, & initiate a response, enabling the
individual to maintain high level of adaptation & homeostasis
The factors that influence neurological health are:
-Diet
-Alcohol intake
-Smoking & other health practices
The cerebral cortex enables the individual to...
-perceive

-emotions
-intellectual activities

Responsible for conscious awareness of sensation & somatosensory stimuli:
Temp., pain, shapes, two-point discrimination and stereognosis testing).
Occipital lobe
-Visual cortex- Receives stimuli from the retina & interprets the visual stimuli in relation to past
, experiences
Temporal lobe
Interprets auditory stimuli
Cerebral Cortex
-Composed of gray matter
-Responsible for all conscious behavior
-Enables the individual to perceive, remember, communicate & initiate voluntary movement

Brain stem consists of
midbrain, pons, medulla oblongata
brain stem function
1. control heartbeat
2.breathing
3.blood preasure
Reflexes are
