The nervous system controls all the organ systems of the body and consists of the brain, spinal cord, and nerves. The brain is the control center located in the skull and made up of the cerebrum, cerebellum, and brain stem. The cerebrum controls thinking and reasoning. The cerebellum controls balance and movement. The brain stem connects to the spinal cord and controls vital functions. The spinal cord transfers messages between the brain and body through nerves. There are sensory, motor, and mixed nerves that carry messages to and from the brain for voluntary and involuntary body actions like reflexes.
Nervous system consists of highly complex structure co-ordinates and controls the body along with the endocrine system.

an overview of the ascending tract of the spinal cord....an anatomical approach to understand the somato-sensory pathway.
Prepared as a class presentation .
Ascending tracts
They are located in the white matter
Conduct afferent information (May or may not reach consciousness)
There are 2 types of information
Exteroceptive : Originates from outside the body (Pain, temperature & touch)
Proprioceptive : Originates from inside the body (From muscles & joints)
Normally there are 3 neurons in an ascending pathway
1st order neuron : Cell body is in the posterior root ganglion
2nd order neuron : Decussates (Crosses to the opposite side) & ascends to a higher level of the CNS
3rd neuron : Located in the thalamus & passes to a sensory region of the cortex

The system that enables the body to coordinate bodily activities is the nervous system. The nervous system is referred to as the control unit of the body. The main function of the nervous system is to integrate and coordinate bodily activities. It also acts as a storehouse of information. All information outside and inside the body are processed and interpreted by the nervous system.
The basic unit of the nervous system is the nerve cell or the neuron. Its main function is to deliver messages. The nervous system is composed of billions of neurons. Some parts of the body have more neurons than the other parts. Extending from the cell body (nucleus) are filaments called nerve fibers. These include one long fiber, the axon, and many shorter fibers called the dendrites.
The neuron has three main parts, the cell body, dendrite, and axon. They all work together to deliver the message from the sense organ to the brain and then back to the organ which does the action.
The fibers of a neuron are covered with a layer of fatty substances called myelin. This layer acts as an insulator. It is also important in speeding up the rate at which nerve impulses are transmitted.
The cell body is the main component of a neuron. It maintains the health of the neuron.
The dendrites are the short fibers around the cell body, Dendrites carry messages into the nerve cell. Thus, they are the receivers. The axons carry messages away from the nerves. Thus, they are the transmitters.
The long fiber of the neuron is the axon. It carries the message from the cell body to the other neurons.
The central nervous system is composed of the brainand the spinal cord.
The brain is the master control of the nervous system that sends messages to the organism so it can respond properly to different stimuli in the environment. It is protected by a bony structure called skullor cranium.
The brain has three main parts: cerebrum, cerebellum and the brain stem. The cerebrum is responsible for controlling speech, memory and intelligence. The cerebellum controls movement and balance. The brain stem connects the brain to the spinal cord and maintains vital automatic functions that include circulations and breathing.

Brain stem
The spinal cord is a cord-like material in the backbone. It extends downward from the medulla oblongata through four fifth of the spinal column. It is protected and encased within a spinal fluid-filled vertebral column/backbone. Like the brain, the spinal cord is a delicate organ. Injuries can cause paralysis or loss of control over voluntary movements.

2. Nervous System
Nervous
System
The Nervous System controls the activities of all the other organ systems of our body.
This system consists of the brain, spinal cord and nerves.
3. Brain
Nervous
System
The brain is the control centre of the body. It controls all body parts and their
activities. The brain coordinates and controls body processes like breathing, digestion
of food, etc. It controls the movement of the body and its various parts.
6. Cerebrum
Nervous
System
The cerebrum is the largest part of the brain. It is responsible for thinking and
reasoning. It controls our thoughts, memory, intelligence, learning and
our sense organs.
7. Cerebellum
Nervous
System
The cerebellum is situated at the back of the brain, below the cerebrum. It controls
balance, movement and muscle coordination. It is because of cerebellum only that we
can stand upright, move around and maintain our balance.
8. Brain Stem
Nervous
System
The brain stem, also known as the medulla, lies beneath the cerebellum. It connects the
rest of the brain to the spinal cord. It controls the vital activities like breathing, digestion
and blood circulation. All information to and from our body passes through the medulla on
the way to and from the brain.
9. Spinal Cord
Nervous
System
The spinal cord is a long, thick bundle of nerves that extends from the medulla. It is
surrounded and protected by the bony vertebral column. However, the length of the spinal
cord is much shorter than the length of the vertebral column. It transfers information
between the brain and the rest of our body through nerves.
10. Nerves
Nervous
System
Nerves form a network of pathways for conducting information throughout the body.
They transfer messages to and from the brain so that it can function efficiently. There
are three kinds of nerves – sensory, motor and mixed.
13. Actions of the body
Nervous
System
In daily life, our body performs many different actions. These can be categorised as –
voluntary actions and involuntary actions.
16. Reflex Action
Nervous
System
A reflex action is also an involuntary action. It is nearly instantaneous (very quick)
movement in response to a stimulus. Its is an automatic action. For example, you sneeze
when dust particles or some other articles enter your nose. Reflex actions are the result of
messages sent to and by the spinal cord.
