NERVE AND MUSCLE CELLS

Question 1

NERVE CELLS what are they ?

Answer 1

nerve cells are specialised to transmit electrical impulses around the body AND synapses are the gaps between the nerve cells
EUKARYOTIC CELSS

Question 2

key parts of the nerve cells are ?

Answer 2

axon- part of the cell that electrical signals travel along
have long nerve cells to increase the distance that the electrical signals travel

myelin sheath-surrounds the nerve cell. stops electrical nerve signals leaking out of the nerve cell which increases the speed of transimissions of elecrical signals

dendrites-branches of a nerve cell
several dendrites spread outwards of the cell body to transfer electrical messages to other neurones

Question 3

MUSCLE CELLS what are they and what do they contain

Answer 3

Produce motion and force
protein fibres- within the cell can contract to make the muscles move
mitochondria-generate a lot of energy for motion
