What type of receptor detects the stimulus?
Sensory receptors are specialized epidermal cells that respond to environmental stimuli and consist of structural and support cells that produce the outward form of the receptor, and the internal neural dendrites that respond to specific stimuli.
What is the stimulus it detects?
They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus….Receptors.

What type of stimuli do humans detect?
Some receptors can detect several different stimuli but they are usually specialised to detect one type of stimulus: light – photoreceptors in the eye. sound – vibration receptors in the ears. touch, pressure, pain and temperature – different receptors in the skin.
What type of stimulus is detected by the sensory receptors of the skin quizlet?
These receptors respond to touch, pressure, vibration, and stretch. These receptors respond to pain caused by external and internal stimuli. Which receptor in the integument detect deep pressure and vibration?
What are some different types of stimuli?
excited by three types of stimuli—mechanical, thermal, and chemical; some endings respond primarily to one type of stimulation, whereas other endings can detect all types.
What kind of stimuli do sensory receptors respond to?
Sensory receptors can be classified by the type of stimulus that generates a response in the receptor. Broadly, sensory receptors respond to one of four primary stimuli: Chemicals (chemoreceptors) Temperature (thermoreceptors) Pressure (mechanoreceptors) Light (photoreceptors)
How are photoreceptors used in the process of vision?
They are a specialised type of neuroepithelial cell that is capable of absorbing light and converting it into an electrical signal in the initial stages of the vision mechanism, a process known as phototransduction. Photoreceptors are packed tightly together, allowing a large volume of light to be absorbed across a small area on the retina.
What kind of neurotransmitter does the photoreceptor release?
Every rod or cone photoreceptor releases the same neurotransmitter, glutamate. However, the effect of glutamate differs in the bipolar cells, depending upon the type of receptor imbedded in that cell’s membrane.
How are rod and cone photoreceptors respond to light?
During vision, rod and cone photoreceptors respond to light intensity and color. During hearing, mechanoreceptors in hair cells of the inner ear detect vibrations conducted from the eardrum.
