neurons Flashcards
1
Q
what do neuron structures consist of
A
Dendrites
Axon
Axon terminal
Cell body
Myelin sheath
Node of ranvier
2
Q
what happens when signals are transferred through a neuron
A
the neuron receives a signal via dendrites that cause the action potential to travel down the axon to the axon terminal
3
Q
what’re the 3 neurons
A
Motor, Relay, Sensory
4
Q
what is the motor neuron
A
Located in the CNS, releases neurotransmitters that bind to muscle receptors, triggering responses
5
Q
what are sensory neurons
A
Located in receptor cells (such as eyes, skin), carries impulses to the CNS which are then translated into sensations (eg vision, touch)
6
Q
what is the relay neuron
A
between sensory and motor neurons in the CNS, allows sensory and motor neurons to communicate
