Anatomical Classification – |
A nervous system division which includes all the nervous system organs
|
|
|
Functional Classification |
A nervous system division which includes its activities |
|
|
a. Brain b. Spinal Cord |
Central Nervous System (CNS) consists of |
|
|
Brain |
which occupy the dorsal cavity |
|
|
Spinal Cord |
act as the integrating and command centers of the nervous system |
|
|
Spinal Cord |
interpret incoming sensory information- |
|
|
Spinal Cord |
issue instructions based on past experiences and current Conditions |
|
|
Peripheral Nervous System (PNS) |
the part of the nervous system outside of the CNS |
|
|
Peripheral Nervous System (PNS) |
consists of the nerves that extend from the brain and spinal cord. |
|
|
Spinal Nerves |
31 pairs |
|
|
Spinal Nerves |
nerves that extend from the spinal cord |
|
|
Spinal Nerves & Cranial Nerves |
carry impulses to and from the spinal cord |
|
|
Cranial Nerves |
12 pairs of nerves |
|
|
Cranial Nerves |
nerves that extend from the brain |
|
|
communication lines and they link all parts of the body |
These nerves(cranial & spinal nerves) serve as _________, by carrying impulses from the sensory receptors to the CNS and from the CNS to the appropriate glands or muscles |
|
|
FUNCTIONAL CLASSIFICATION
|
Concerned only with PNS structures |
|
|
FUNCTIONAL CLASSIFICATION |
It is subdivided into Sensory or Afferent Division & Motor or Efferent Division |
|
|
Sensory or Afferent Division |
consists of nerve fibers that convey impulses to the CNS from the sensory receptors located in the various parts of the body |
|
|
Sensory or Afferent Division |
keeps the CNS constantly informed of events going on both inside and outside of the body. |
|
|
Motor or Efferent Division – |
carries impulses from the CNS to effector organs, the muscles and glands; that is, they effect a motor response. |
|
|
Voluntary Nervous System or Somatic Nervous System |
allows us to consciously or voluntarily control our skeletal muscles |
|
|
Involuntary Nervous System or Autonomic Nervous System |
regulates events that are automatic or involuntary, such as the activity of the smooth and cardiac muscles and glands. |
|
|
Sympathetic Nervous System Parasympathetic Nervous System
|
2 subdivisions of Involuntary Nervous System or Autonomic Nervous System |
|
|
Voluntary Nervous System or Somatic Nervous System
Involuntary Nervous System or Autonomic Nervous System
|
2 subdivisions of Motor or Efferent Division |
|
|
Sensory input |
Functions of the Nervous System which is responsible of gathering informationto monitor changes occurring inside and outside the body
|
|
|
Changes = stimuli |
Changes =_____ |
|
|
Motor output
|
A response to integrated stimuli
|
|
|
Motor output |
The response activates muscles or glands |
|
|
BRAIN |
technically called ENCEPHALON |
