Most reflex arcs are:
Correct answer: B. Polysynaptic reflex
- A. Monosynaptic reflex
- B. Polysynaptic reflex
- C. Hemi Synaptic Reflex
- D. None of these
Explanation
Most reflex arcs are "b) Polysynaptic reflex." A polysynaptic reflex involves multiple synapses and interneurons between the sensory neuron and the motor neuron in the reflex arc. In this type of reflex, sensory information from the sensory neuron is transmitted to interneurons in the spinal cord or brainstem before reaching the motor neurons that initiate the appropriate response.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
