Слайд 2It consists of the brain, the spinal cord, which runs

from the brain and down through your backbone, and a

gigantic network of nerves

It consists of the brain, the spinal cord, which runs from the brain and down through your

Слайд 3The brain is like the central computer for the nervous

system. It receives messages from different parts of the body,

and then tells the body how to react.

The brain is like the central computer for the nervous system. It receives messages from different parts

Слайд 4If you touch a hot pan by accident, for example,

the nerves in your skin form a message of pain.

The message gets passed on through the nerves in the spinal cord to the nerves in the brain. The brain takes this message, translates it, then sends a message back telling the muscles to pull your hand away from the heat. This all happens in less than a second!

If you touch a hot pan by accident, for example, the nerves in your skin form a

Слайд 5The brain is a very complex organ with many different

parts.

Слайд 6 The biggest part is the cerebrum, responsible for intelligence,

memory, personality, emotion, speech and the ability to feel and

move.

Слайд 7Next is the smaller cerebellum, controlling balance, movement and coordination,

and the brain stem. This is responsible for taking in,

sending out and coordinating all of the brain's messages - just like a secretary! It also controls many automatic body functions such as breathing, heart rate and digestion.

Next is the smaller cerebellum, controlling balance, movement and coordination, and the brain stem. This is responsible

Слайд 8The thalamus carries messages from the sensory organs like the

eyes, ears, nose and fingers to the cerebrum, and the

hypothalamus controls other automatic processes such as body temperature and appetite.

The thalamus carries messages from the sensory organs like the eyes, ears, nose and fingers to the

Слайд 9Lastly, there is the tiny pituitary gland, which produces and

releases hormones to control growth, metabolism, our response to stress,

and many other things.

Lastly, there is the tiny pituitary gland, which produces and releases hormones to control growth, metabolism, our

Слайд 10Nerve cells, or neurons, are like long, thin threads with

fingers, called dendrites, at each end. The dendrites of one

neuron almost touch the dendrites of the next neuron.

Nerve cells, or neurons, are like long, thin threads with fingers, called dendrites, at each end. The

Слайд 11When a neuron is stimulated, by heat, touch or sound,

for example, or by some other message, it actually generates

a tiny electrical signal.

This releases chemicals that enable the signal to be passed on from the dendrites of one neuron to the next, until the message reaches the brain.

When a neuron is stimulated, by heat, touch or sound, for example, or by some other message,

Слайд 12The brain alone contains around 100 billion neurons!
