Spinal Cord and brain

Description about How spinal cord and brain are connected

1. Spinal Cord and
Brain

2. Introduction
■The nervous system divide into two parts:
1.Central nervous system
2.Peripheral nervous system
■Central nervous system consists of brain and spinal cord.
■This complex system is part of everything we do.It controls
the thingslike walk and talk and the things our body does
automatically.
■The central nervous system is also involved with our
sensesas well as our emotions, thoughts, and memory.

3. Brain
■The brain is a soft, spongy mass of nerve cells and
supportive tissue.
■It has three major parts: Forebrain, Mid-brain , and Hind-
brain.
■Fore-Brain: It is the largest area of brain. Following
are the important parts of this region:
1.Thalamus
2.Hypothalamus
3.Cerebrum

4. Brain
Mid-Brain: It lies between hind-brain and fore-
brain and connect the two. It receive the information
and send it to appropriate part of fore-brain.
Hind-brain: It is the lower part of brainstem. It
consists of three major parts.
1.Medulla oblongata
2.Cerebellum
3.Pons

6. Spinal cord
The spinal cord is tubular bundle of nerves. It start
from brain stem and extends to lower back.
The outer region of spinal cord is made of white
matter.
The central region is butterfly shaped that surrounds
the central canal. It is made of grey matter.
Spinal nerve has two roots:
The dorsal root contains sensory axons and a
ganglion.

7. Spinal cord
The ventral root contains axons of motor neurons.
Spinal perform two main functions:
1.It serve as a link between body parts and brain.
2.Spinal cord also acts as a coordinator, responsible for
some simple reflexives.
Spinal cord is 40cm long and as wide as your thumb
for most of length.
