Answer 1

• how neurons send message to another
• 6.ANSWER-There are messages which are carried in the form of electrical impulses to and from brain and other parts through cells called as neurons.A neuron has a cell body which directs all the activities of the neuron,Dendrites which receive messages from the other nerve cells and an axon which is a long single fiber that sends messages from the cell body to the dendrites of the other neurons,or muscles.Myelin sheath which insulates the axon,covers most neurons and helps in sending nerve signals faster.
• The messages from one neuron to another neuron takes places viz the release of a chemical substance in the space between axon and dendrites.These chemical substances are called neurotransmitters released into the synapse,and the process is called neurotransmission.
• When neurons communicate,an electrical impluse tends to trigger th release of the neurotransmitters from the axon into the synapse,and these neurotransmitters cross the synpase and bind to special molecules on the other side,which is called receptors.Receptors are present on the dendrites and the receive the message.
