What are the two long ‘arms’ of a sensory neurone called?
axon and drendron
tron and bogon
dendrite and cell body
In what order does an impulse travel through a sensory neurone?
dendrite, dendron, axon, axon terminal
dendron, dendrite, axon terminal, axon
axon terminal, axon, dendron, dendrite
Why are sensory neurones so long?
to carry impulses quickly over long distances
they grow really fast
there would be too many cells if they were short
What is the name of the fatty sheath that can surround dendrons and axons?
myelin sheath
fatty cells
nodes of ranvier
What does the myelin sheath do?
makes the impulses travel faster
makes the impulses travel slower
protects the neurone
