GENERAL HISTOLOGY

Detailed explanation-1: -Sensory receptors detect changes in the internal as well as external environment. Sensory receptors comprise specialised cells close to neurons or neuron endings, which are a part of the afferent neurons and send signals to the central nervous system and brain for processing and integration.

Detailed explanation-2: -A sensory neuron (sometimes referred to as an afferent neuron) is a nerve cell that detects and responds to external signals. Sensory neurons receive information via their receptors, which are part of the peripheral nervous system, and convert this information into electrical impulses.
