ANATOMY

Detailed explanation-1: -Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded potentials. This process is called sensory transduction.

Detailed explanation-2: -Sensory receptors. Sensory receptors have specialized functions, and respond to environmental changes in stimuli. Usually, activation of these receptors by stimuli causes graded potentials triggering nerve impulses along the afferent PNS fibers reaching the CNS.

Detailed explanation-3: -Sensory neurons are the afferent limb of somatosensory neural pathways. The neuron consists of a cell body, axon, and dendrites. Dendrites are finger-like projections that receive sensory input and transmit the signal through the axon to the cell body.

Detailed explanation-4: -Sensory receptors are either specialized cells associated with sensory neurons or the specialized ends of sensory neurons that are a part of the peripheral nervous system, and they are used to receive information about the environment (internal or external).
