Neurones Flashcards
1
Q
neurone
A
cells that transmit information from receptors to effectors
2
Q
sensory neurone
A
carry impulses from receptors to effectors
3
Q
motor neurone
A
carry impulses from the CNS to effector organs
4
Q
relay neurone
A
receive impulses from a sensory neurone and relay them to motor neurones
5
Q
dendrites
A
carry nervous impulses towards a cell body
6
Q
axons
A
carry nervous impulses away from the cell body
7
Q
Schwann cells
A
responsible for forming the the myelin sheath around the neurone.
8
Q
Schwann cells location
A
wrapped around the axon of the neurone
9
Q
nodes of ranvier
A
gaps between adjacent Schwann cells
10
Q
myelin sheath
A
insulate neurones which increases the speed of impulse transmission
11
Q
difference between myelinated and non-myelinated neurones.
A
- does not contain a myelin sheath
- conduct impulses slower
- found in the autonomic nervous system (supplies internal organs like stomach )
