Detects and reacts to stimuli

What does the nervous system mean for humans?

It means that humans can react to their surroundings and coordinate their behaviour

What is the nervous system made up of?

-Central nervous system
-Receptors

-Sensory Neurones

-Effectors

-Motor Neurones

What does the central nervous system consist of?

The brain and spinal cord

What is the central nervous system connected to the body by?

Sensory neurones and motor neurones

What do the receptors do?

Receptors are the cells that detect stimulus

Different receptors detect different stimulus. Give an example of this.

Receptors in the ears detect sound

What do the sensory neurones do?

They carry information as electrical impulses from the receptors to the central nervous system

What do the effectors do?

Effectors respond to electrical impulses and bring out a change

What parts of the body are effectors?

Muscles and glands

How do muscles respond?

Muscles contract

How do glands respond?

Glands release hormones

What do the motor neurones do?

They carry electrical impulses from the central nervous system to the effectors

What does the central nervous system do?

It recieves information from the receptors and then coordinates a response

How does the nervous system work?

-The receptors detect a stimulus.
-Sensory neurones carry the information from the receptors to the central nervous system.

-The central nervous system then coordinates a response.

-The central nervous system sends information to the effectors along the motor neurones.

-The effectors then respond.
