Neuron Nerve Tissue - Connective tissue 5

Question 1

Specialised for ..?

Answer 1

Conduction of electrical impulses from one region of the body to another

Question 2

Grouped into?

Answer 2

Central Nervous System and Spinal cord
Peripheral Nervous system

Question 3

Nerve tissue consists of 2 main cell kinds?

Answer 3

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

Question 4

What do neurones consist of?

Answer 4

Cell body
1 axon - impulse away from cell
Many dentrites - impulse to cell

Question 5

Dentrites

Answer 5

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

Question 6

Cell body

Answer 6

Contains nucleus, mitochondria, ribosomes and other organelles and inclusions

Question 7

Axon

Answer 7

Conducts nerve impulse towards synaptic terminals

Question 8

Synapses

Answer 8

Electrical stimulation is transmitted onto dentrites via synapses

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