Cells of the nervous system -Neurons

Function of neurons

Conduct nerve impulses around the body

Function of the glial cells

Produce the myelin sheath

And supports neurons

Which part of the neuron contains the nucleus

Cell body

what is the dendrite

Part of neuron

Function of the dendrite

Branched nerve fibres which receive nerve impulses and pass them towards a cell body

Function of the axon

A single nerve fibre that carries nerve impulses away from a cell body -insulated by a fatty sheath

Function of the myelin sheath

Insulates the axon and increases the speed of impulse conduction

Definition of myelination

Process that develops the layer of insulation, myelin around axon fibres, which continues from birth to adolescence

Reason for responses to stimuli during first two years not being as rapid or co-ordinated as in older people.

Myelination continues from birth to adolescence

Where are neurotransmitters stored?
