Which of the following is the correct route of transmission of impulses along a reflex arc?
Answer Details
The correct route of transmission of impulses along a reflex arc is:
"Receptor → sensory neurone → synapse → intermediate neurone → synapse → motor neurone → effector"
A reflex arc is a neural pathway that controls reflex actions, and it involves a series of neurons that work together to produce a quick, automatic response to a stimulus. The pathway starts with a receptor, which detects the stimulus and sends a signal to a sensory neuron. The sensory neuron then carries the signal to the spinal cord or brainstem, where it synapses with an intermediate neuron. The intermediate neuron, in turn, synapses with a motor neuron, which carries the signal to the effector, which is the muscle or gland that produces the response.
The correct option describes this pathway in the correct order: from the receptor, to the sensory neuron, to the intermediate neuron, to the motor neuron, and finally to the effector.
