Sensory receptor
In a sensory system, a sensory receptor is a sensory nerve ending that responds to a stimulus in the internal or external environment of an organism. In response to stimuli, the sensory receptor initi...

Stanford Engineers Create Artificial Skin That Can Send Pressure Sensation To Brain Cell
Stanford engineers have created a plastic "skin" that can detect how hard it is being pressed and generate an electric signal to deliver this sensory input directly to a living brain cell. Zhenan Bao,...

Stimulus (physiology)
In physiology, a stimulus (plural stimuli) is a detectable change in the internal or external environment. The ability of an organism or organ to respond to external stimuli is called sensitivity. Whe...
Transduction (physiology)
In physiology, sensory transduction is the conversion of a sensory stimulus from one form to another.Transduction in the nervous system typically refers to stimulus alerting events wherein a physical ...
Stimulus modality
Stimulus modality, also called sensory modality, is one aspect of a stimulus or what we perceive after a stimulus. For example the temperature modality is registered after heat or cold stimulate a rec...

Chemoreceptor
A chemoreceptor, also known as chemosensor, is a sensory receptor that transduces a chemical signal into an action potential. In more general terms, a chemosensor detects certain chemical stimuli in t...
Electroreception
Electroreception is the biological ability to perceive natural electrical stimuli. It has been observed almost exclusively in aquatic or amphibious animals, since water is a much better conductor than...

Mechanoreceptor
A mechanoreceptor is a sensory receptor that responds to mechanical pressure or distortion. Normally there are four main types in glabrous skin: Pacinian corpuscles, Meissner's corpuscles, Merkel's di...
Nociceptor
A nociceptor is a receptor of a sensory neuron (nerve cell) that responds to potentially damaging stimuli by sending signals to the spinal cord and brain. This process, called nociception, usually ca...
Olfactory receptor
Olfactory receptors expressed in the cell membranes of olfactory receptor neurons are responsible for the detection of odor molecules. Activated olfactory receptors are the initial player in a signal...
Osmoreceptor
An osmoreceptor is a sensory receptor primarily found in the hypothalamus of most homeothermic organisms that detects changes in osmotic pressure. Osmoreceptors can be found in several structures, inc...
Photoreceptor cell
A photoreceptor cell is a specialized type of neuron found in the retina that is capable of phototransduction. The great biological importance of photoreceptors is that they convert light (visible ele...

Proprioception
Proprioception (/ˌproʊpri.ɵˈsɛpʃən/ PRO-pree-o-SEP-shən), from Latin proprius, meaning "one's own", "individual," and perception, is the sense of the relative position of neighbouring parts of the bod...

Thermoreceptor
A thermoreceptor is a sensory receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range. In ...
Cutaneous receptor
A cutaneous receptor is a type of sensory receptor found in the dermis or epidermis. They are a part of the somatosensory system. Cutaneous receptors include e.g. cutaneous mechanoreceptors, nocicepto...
Hair cell
Hair cells are the sensory receptors of both the auditory system and the vestibular system in all vertebrates. Through mechanotransduction, hair cells detect movement in their environment. In mammals,...

Sensory neuron
Sensory neurons are nerve cells that transmit sensory information (sight, sound, feeling, etc.). They are activated by sensory input, and send projections to other elements of the nervous system, ul...
Sensory nerve
A sensory nerve is an enclosed, cable-like bundle of sensory nerve fibers in the peripheral nervous system.
