Your body needs to coordinate its actions and respond to the world around it. This is the job of the nervous system, which uses specialised cells called neurones to send information rapidly around the body as electrical impulses.
Quiz#2
What type of signal is transmitted along a neurone?
an electrical impulse
Lesson#3
The nervous system has two main parts. The Central Nervous System, or CNS, consists of the brain and spinal cord. The Peripheral Nervous System, or PNS, is made up of all the nerves that connect the rest of the body to the CNS.
Quiz#4
What are the two components of the central nervous system?
the brain and the spinal cord
Quiz#5
What does the peripheral nervous system consist of?
nerves outside the brain and spinal cord
Lesson#6
There are three types of neurone you need to know. Sensory neurones carry impulses from sense organs, or receptors, to the CNS. Motor neurones carry impulses from the CNS to muscles or glands, called effectors. Relay neurones are found inside the CNS and connect other neurones.
