2. • Master controlling and communicating
system of the body
• Controls and coordinates all essential
functions of the human body
• Receives sensory input, makes decisions,
and then orders body responses

4. • SENSORY FUNCTION: Nervous system
uses its millions of sensory receptors to
monitor changes occurring both inside
and outside of the body. Those changes
are called STIMULI, and the gathered
information is called Sensory Input.

5. • INTEGRATIVE FUNCTION : The Nervous
System process and interprets the sensory
input ad makes decisions about what should
be done at each moment—a process called
Integration.

6. • MOTOR FUNCTION: The Nervous System
then sends information to muscles, glands,
and organs (effectors) so they can respond
correctly, such as muscular contraction or
glandular secretions.

8. • Consists of the brain and the spinal cord, which act as
the integrating & command centers of the nervous
system
• Interpret incoming sensory information and issue
instructions based on past experience and current
conditions.

9. • Located within the cranial cavity of
the skull and consists of different
hemispheres
• Center for all thoughts, memories,
judgements and emotions

10. • Reflex center and conduction
pathway which is found in the
vertebral column.

11. • It is the part of the nervous system outside the CNS.
• They link all parts of the body by carrying impulses from
the sensory receptors to the CNS and from the CNS to
the appropriate glands or muscles.
• It consists mainly of the nerves that extend from the
brain and spinal cord.
• Cranial nerves – carry impulses to and from the brain.
• Spinal nerves – carry impulses to and from the spinal
cord.

13. • Voluntary motor commands – such as moving muscles
to walk or talk, are controlled by the somatic nervous
system
• Involuntary motor commands – such as digestion and
heartbeat, are controlled by the autonomic nervous
system.
 Sympathetic Nervous System – “fight or flight” system
 Parasympathetic Nervous System – “rest & repose” system

14. • Frontal Lobe – reasoning, planning, parts of speech,
movement, emotions, and problem solving
• Parietal Lobe – movement, orientation, recognition,
perception of stimuli such as touch
• Occipital Lobe – visual processing
• Temporal Lobe – perception and recognition of
auditory stimuli, smell and memory

15. • Largest part of the human brain
• Associated with higher brain function such as thought
and action
• Cerebral cortex - exterior surface of the cerebrum, is
convoluted or folded grayish layer of cell bodies known
as GRAY MATTER.
- controls perception, memory, and all
higher cognitive functions, including the ability to
concentrate, reason and think in abstract form.
