Q

Nerve tissue consists of 2 main cell kinds?

A

Neurons - cell, axon and dentrites
Neuroglia (‘Glue’ cells) supports connective tissue that forms myelin sheath to protect, repair and supply nutrients to the neuron.

Q

Dentrites

A

Impulse to cell
Branched protoplasm is extension of nerve cell
Receptors - neurone receives its information - signal travels down ‘axon’

Q

Synapses

A

Electrical stimulation is transmitted onto dentrites via synapses

Synapse - point which impulse travels from one neurone to another .. axon .. to the next dentrite…
