NERVOUS SYSTEM
The complete network of
neurons that regulates
bodily processes and is
ultimately responsible for
all aspects of conscious
experience.
DIVISIONS OF NERVOUS SYSTEM
Nervous system is divided into two parts:
 CENTRAL NERVOUS SYSTEM
 PERIPHERAL NERVOUS SYSTEM
CENTRAL NERVOUS SYSTEM
Central nervous system occupies the
central position in the body. Central Nervous
System is divided into two parts:
1. BRAIN
2. SPINAL CORD
1. BRAIN:
Brain interprets and stores information
and sends orders to muscles, glands and
organs. Brain is divided into:
a). Fore Brain
b). Mid Brain
c). Hind brain
2. SPINAL CORD:
Spinal cord is the pathway
connecting brain and the Peripheral Nervous
System.
PERIPHERAL NERVOUS SYSTEM
The portion of the nervous system that
connects internal organs, glands and
voluntary and involuntary muscles to the
Central Nervous System.
Peripheral Nervous System is divided
into two parts:
A. SOMATIC NERVOUS SYSTEM
B. AUTONOMIC NERVOUS SYSTEM
A. Somatic Nervous System:
The portion of the peripheral nervous
system that connects the brain and the
spinal cord (central nervous system) to
voluntary muscles. Somatic Nervous
System is divided into:
a). Cranial nerves
b). Spinal nerves
B. Autonomic Nervous System:
The portion of the Peripheral Nervous
System that connects the brain and spinal
cord (central nervous system) to internal
organs, glands and involuntary muscles.
Autonomic Nervous System is divided into:
a). Sympathetic Autonomic Nervous System
b). Parasympathetic Autonomic Nervous
System
