Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following structures are part of a reflex arc?
A
2 motor neurons
B
a motor neuron, a sensory neuron and an interneuron
C
only a motor neuron and sensory neuron
D
only a sensory neuron and interneuron
Explanation: 

Detailed explanation-1: -Thus, the correct sequence is a sensory receptor, sensory neuron, interneuron, motor neuron and effector.

Detailed explanation-2: -The reflex arc is a special type of neural circuit that begins with a sensory neuron at a receptor (e.g., a pain receptor in the fingertip) and ends with a motor neuron at an effector (e.g., a skeletal muscle).

Detailed explanation-3: -What components of the nervous system are involved in a reflex arc? A reflex arc involved an afferent or sensory neuron, an interneuron, and an efferent or motor neuron.
