NERVOUS SYSTEM IS THE BASE OF ALL ACTIVITIES EXIST IN HUMAN BODY.

2. STRUCTURE AND PROPERTIES OF
NEURON
• The primary components of
the neuron are the soma
(cell body), the axon (a long
slender projection that
conducts electrical impulses
away from the cell body),
dendrites (tree-
like structures that receive
messages from
other neurons), and
synapses (specialized
junctions
between neurons).

3. SUBDIVISION OF NERVOUS SYSTEM
AND THEIR FUNCTION
• Divisions of the Nervous System
• CENTRAL NERVOUS SYSTEM (CNS)
• PERIPHERAL NERVOUS SYSTEM (PNS)
• The CNS is comprised of the brain, cerebellum
and spinal cord. Remaining neurons, and
associated cells, distributed throughout the body
form the PNS.
• The nervous system has three broad functions:
sensory input, information processing, and motor
output.

4. SENSORY AND MOTOR NERVOUS
SYSTEM
• Peripheral neurons are of two types, sensory
and motor. Sensory (afferent) neurons bring
information about the world within and
around the body from sense organs to the
brain and spinal cord, while motor (efferent)
neurons carry messages from the brain and
spinal cord out to the muscles and glands.

7. HIGHER FUNCTIONS OF NERVOUS
SYSTEM
• The nervous system is involved in receiving
information about the environment around us
(sensation) and generating responses to that
information (motor responses). The nervous
system can be divided into regions that are
responsible for sensation (sensory functions)
and for the response (motor functions).

8. SYNAPSE
• In the nervous system,
a synapse is a structure
that permits a neuron
(or nerve cell) to pass
an electrical or chemical
signal to another
neuron or to the target
effectors cell.

9. REFLEXES CEREBROSPINAL FLUID
• Cerebrospinal fluid has
three main functions:
CSF protects brain and
spinal cord from
trauma. CSF
supplies nutrients to ne
rvous system tissue.
CSF removes waste
products from cerebral
metabolism.

10. BLOOD BRAIN AND BLOOD CSF
BARRIER
• Blood-CSF
barrier separates
the cerebrospinal
fluid and blood. ... 1)
Choroidal epithelial cells
interconnected by tight
junctions (which are more
permeable than the
junctions between the
endothelial cells
of brain capillaries) and
secreting
the cerebrospinal fluid.

11. TYPES OF GLAND
(ENDOCRINE/EXOCRINE)
• Examples of exocrine
(ductus) glands are sweat,
salivary, sebaceous,
mucous gland.
An endocrine
gland (ductless) is
a gland which secretes its
products directly into the
blood stream. Examples
of endocrine glands are
pituitary gland, ovaries,
testes, thyroid gland,
adrenal glands

12. IMP ENDOCRINE AND EXOCINAL GLAND AND
TYPES HORMONE AND THEIR FINCTION.
• Examples of exocrine (ductus)
glands are sweat, salivary,
sebaceous, mucous gland.
• There are glands that have
both exocrine and endocrine
functions. Pancreas, testes,
and ovaries perform
both exocrine and endocrine
functions. For
example, the pancreas acts as
an endocrine gland and
secretes insulin. It also acts as
an exocrine gland and
secretes pancreatic juice
into the pancreatic duct.
