Receptors receive information from envirement and convey to N.S.
Sensory receptors that respond to stimuli from outside the body are known as exteroceptors. These receptors detect environmental stimuli such as light, sound, taste, touch, and temperature. Common types of exteroceptors include photoreceptors in the eyes, mechanoreceptors in the skin, and chemoreceptors in the nose and mouth. They play a crucial role in helping organisms perceive and interact with their surroundings.
Phasic receptors
Atropine does not only block nicotinic receptors but also acetylcholine at muscarinic receptors
Tonic receptors have little to no adaptation while phasic receptors adapt fast!
False. While beta-adrenergic receptors are commonly found in the heart, there are also other types of receptors present, such as alpha-adrenergic receptors and muscarinic receptors, that play a role in regulating heart function.
Almost everything with a structural function, enzymes, pores in the cell membrane to pump ions, receptors, etc.
somatic receptors and special receptors
Olfactory receptors
There are more cold receptors in the skin than warm receptors.
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.

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.
More cool receptors than warm receptors in the skin.
The sensory receptors for smell are referred to as olfactory receptors.
Olfactory receptors are G protein-coupled receptors (GPCRs). These receptors are located in the olfactory epithelium of the nasal cavity and are responsible for detecting odor molecules.
Phasic receptors
Organisms gather information about their environment through sensory receptors that detect stimuli such as light, sound, chemicals, and touch. They also use behaviors like foraging, searching, and exploring to gather information from their surroundings.
