Sensory neurone
Explanation
Sensory neurones are responsible for transmitting impulses from the receptor to the central nervous system in a reflex arc.
Common mistake
Misidentifying Neurones
Students often confuse the roles of sensory, relay, and motor neurones when interpreting a reflex arc diagram.
To fix this, students should review the functions of each type of neurone: sensory neurones carry impulses from receptors to the CNS, relay neurones connect sensory and motor neurones within the CNS, and motor neurones transmit impulses from the CNS to effectors.
