A receptor is generally a recognition molecule situated on the surface of a cell. A receptor is a molecule that is sensitive to a particular signal and is also able to transmit information to the nucleus in order to control gene regulation. In order for a receptor to function, it must first be activated. The binding of a ligand to the receptor places the receptor in the activated state. Once the receptor is activated, it is now able to transmit signal to the interior of the cell.
Sensory receptors detect changes in the environment known as stimuli. These receptors are specialized cells that send signals to the brain or spinal cord in response to specific types of stimuli such as light, sound, pressure, or chemical signals.
Phasic sensory receptors are specialized nerve endings that rapidly adapt to a constant stimulus, such as the touch receptors in the skin. Tonic sensory receptors, on the other hand, do not adapt as quickly and provide continuous information about a stimulus, like the proprioceptors that sense body position.
The skin is a primary site where you can find many sensory receptors. It contains various types of receptors that respond to touch, pressure, temperature, and pain. These receptors enable the body to perceive and interact with its environment, playing a crucial role in sensory perception. Other areas with sensory receptors include the eyes, ears, and taste buds, which are specialized for vision, hearing, and taste, respectively.
Sensory impulses at receptors are typically stimulated by specific environmental stimuli such as light, sound, touch, temperature, or chemicals. These stimuli activate specialized receptors on sensory neurons, which then generate neural signals that are transmitted to the brain for further processing and interpretation.
Vestibulocochlear is the term for the nerve that carries sound and balance information to the brain from the ear.
The sensory receptors for smell are referred to as olfactory receptors.
somatic receptors and special receptors
The dermis layer of the skin is composed of thousands of sensory receptors, including touch receptors, temperature receptors, and pain receptors. These receptors help you to feel sensations and respond to your environment.
Sensory receptors enable you to respond to stimuli in the environment of an organism. Some sensory receptors respond to taste and smell while others respond to physical stimuli.
The eyes, nose, skin and tongue HAVE sensory receptors.
It transmit electrical signals from sensory receptors and to effectors which control their activity.
It all depends on the sensory receptors affected by continuous stimulus applied. It can cause complete damage to the receptors and or prevent them from receiving the correct signals.
The sensory receptors for the eyes are the optic nerve and the retina. The sensory receptor for the nose are the olfactory nerves.

Adaptation of sensory receptors refers to the way in which our senses changed under different circumstances and stimuli.
Sensory receptors that respond to heavy pressure are called Pacinian corpuscles.
The Dermis layer contains the sensory nerve fiber, so it is the Dermis layer that contains sensory receptors for touch.
