Question
The diagram below shows three different types of neurons along a reflex.
(a) Identify the neuron labeled 1, 2 and 3
(b) Using arrow show the direction of impulse transmission on the diagram.
(c) Name the part of the spinal cord where the cell bodies of neuron 2 and 3 are located
(d) Describe the transmission impulses across the part labeled P.

(c) Name the part of the spinal cord where the cell bodies of neuron 2 and 3 are located
(d) Describe the transmission impulses across the part labeled P.
Answer
(a)
1. Sensory /Afferent Neuron
2. Relay/intermediate Neuron
3. Motor/Efferent Neuron
(b)
(c) Grey matter
(d) Impulse reaching the dendrite end of relay neuron causes the synaptic vesicle to release a acetylcholine, (transmitter substance) that diffuse across the cliff and causes the depolarization of the motor neuron.
