Receptors can be classified based on their location into two main categories: exteroceptors and interoceptors. Exteroceptors are located on the body's surface and respond to external stimuli, such as light, sound, and touch. In contrast, interoceptors are found within the body and monitor internal conditions, such as blood pressure, temperature, and the status of internal organs. This classification helps in understanding how organisms perceive and respond to their environment.
You can consider it as general.
There are two main types of receptors for acetylcholine: muscarinic receptors, which are G-protein coupled receptors, and nicotinic receptors, which are ligand-gated ion channels. Each type of receptor is further classified into different subtypes based on their structure and function.
The intracellular receptors differ from membrane receptors based on their location. Membrane receptors are usually on the plasma membrane but the intracellular receptors are found inside the cell.
Touch receptors detect mechanical stimuli such as pressure, vibration, and temperature. These specialized receptors are found in the skin and relay information to the brain about various sensations related to touch.
If there were a known number of stimuli, then this world that we live in would not have its awe of the unknown. Why would know want to know how many things there are that could possibly arouse any sort of emotion, it would be like we were a character in a video game, why keep playing if you have already beat the game... Anyways, by types of stimuli, you define the type of the stimuli by the emotion you interpret to arouse. Last time I checked there is no known list of emotions known and accepted by all psychologists, there are micro emotions and so forth.
Receptors for taste are classified as gustatory receptors, while receptors for olfaction are classified as olfactory receptors. Gustatory receptors are found on taste buds located on the tongue, while olfactory receptors are found in the nasal cavity.
somatic receptors and special receptors
Taste receptors are classified as chemoreceptors, specialized sensory receptors that respond to chemical stimuli in the form of tastes. Smell receptors are classified as olfactory receptors, which are designed to detect and respond to odor molecules in the environment.
Proprioceptors are classified by their location within the body and their function in providing feedback about body position, movement, and balance. They can be further categorized as muscle spindles, golgi tendon organs, and joint receptors.
thermoreceptor
Silent receptors are a proportion of total receptors that are to be occupied before there is any response. It is an model and these are not a distinct subgroup of receptors.
As chemical reacions
Taste and smell receptors are classified as chemoreceptors because they both respond to chemical stimuli. These receptors detect specific molecules in the environment and send signals to the brain, which are then interpreted as taste or smell.
You can consider it as general.
In the inner ear.
A stretch receptors is classified as a mechanoreceptor.
chemical stimuli in the environment. Taste receptors on the tongue detect chemicals in food, while smell receptors in the nose detect chemicals in the air. Both types of receptors send signals to the brain for interpretation.
