The nervous system, neurons and synapses

Question 1

The role of the nervous system

Answer 1

Nervous system acts as bodies control centre . It interprets the sensory information which enters the body via senses like touch and taste and sends information to glands and muscles

Question 2

What is the CNS and peripheral nervous system ?

Answer 2

consists of brain and spinal cord

peripheral nervous system = consist of nerves that branch out from brain and spinal cord throughout your body

Question 3

What is the nervous system made up of ?

Answer 3

neurons

Question 4

Neuron parts and function

Answer 4

Cell body covered in dendrites and an axon.
Dendrites receive information from other neurons and transmit this information via electrical impulse to cell body. Impulse then transmitted to other neurons by axon.

Question 5

What’s a synapse ?

Answer 5

located at the end of an axon . Electrical impulse travel along axon and trigger release of neurotransmitters which are chemical messengers to be diffused across synapses - gap between two neurons

When they reach the other side, the neurotransmitters bind with receptors on next neuron. There are different kinds of receptors and the neurotransmitters will only bind with the receptors that are designed to specifically receive them. message then passed along neuron to next one in same way.
