The nervous system has three main parts: the brain, spinal cord, and nerves. The brain receives information and sends messages to the body via the spinal cord and nerves. The brain is made up of the cerebrum, cerebellum, and brainstem. Neurons are the basic building blocks of the nervous system and are composed of axons, dendrites, and a cell body. The five senses - sight, hearing, touch, smell, and taste - allow us to perceive the world around us. Each sense has specialized sensory organs that detect stimuli and relay this information to the brain via nerves.

2. Wich organs make up the nervous
system?
 The nervous system have three parts :
 The Brain : recives the information and send a message
to a part of the body.
 The Spinal Cord : conect the brain to the rest ob the
body.
 The Nerves : Connect the spinal cord to our muscles,
joints and skin.
There are to types of nerves:
Motor nervs and Sensory nerves

3. What is the brain made up of ?
 The cerebrum : is the largest and most complex part of
the brain
 The cerebellum : is the responsible for balance,
movement and cordination.
 The brainstem : coordinates all the messages going in
and out of the brain to and from the spinal cord.
