Practice questions on Reflex Arc
Reflex arc:
- Is composed of receptors, afferent and efferent neurones only.
- Always involves a monosynaptic pathway.
- Is the functional unit of nervous system.
- Depends on a center inside CNS.
- Is the structural unit of the nervous system. ✅ Answer: D
Answer: A. A reflex arc typically includes an integration center, which for most reflexes is located within the central nervous system (CNS).
Which of the following structures is a component of a reflex arc?
- Cerebral cortex
- Motor neuron
- Association neuron
- Sensory receptor
Answer: D. A reflex arc typically includes a sensory receptor, an afferent (sensory) neuron, one or more interneurons (association neurons) in the CNS, an efferent (motor) neuron, and an effector (muscle or gland). While not all reflexes involve all these components explicitly (e.g., monosynaptic reflexes omit interneurons, and the brain might not be directly involved in simple reflexes), these are the typical components.
