Sensory nerve of a reflex arc carries information from the receptor cells to the ______.
पर्याय
spinal cord
brain
muscles of the effector organ
bones of the receptor organ
उत्तर
Sensory nerve of a reflex arc carries information from the receptor cells to the spinal cord.
Explanation:
A reflex action, or reflex, is an automatic reaction to a stimulus that is not under conscious control. A reflex arc is a neural pathway that mediates a reflex action. The Central Nervous System (CNS), which is composed of the brain and spinal cord, receives data from the receptor cell via the sensory nerve of a reflex arc. The sensory nerve fibres in the body terminate in the spinal cord, where motor neurons that control the effector organ share synapses with interneurons to transmit information.
