What is the name for the place on the neuron where a signal is transmitted to the next neuron
axon terminal
Oops!
Okay!
What does a sensory neuron do?
transmits nerve impulses away from receptor cells when a stimulus is detected
Oops!
Okay!
What is the function of the myelin sheath?
it makes the nerve impulses travel faster

Okay!
What does the CNS stand for and what makes it up?
Central nervous system is made up of the brain and spinal cord

Describe the pathway for a reflex arc
receptor → sensory neurone → relay neurone → motor neurone → effector
Oops!
Okay!
How do sensory and relay neurons differ in structure?
Sensory neurons are longer as they have to transmit messages from distant parts of the body to the CNS; relay neurons have a short axon
Oops!
Okay!
What does a relay neuron do?
