Innehållsförteckning
Vilka olika sinnesceller har vi i huden?
Känselkroppar registrerar känsel Du känner beröring, tryck, värme och kyla med hjälp av så kallade känselkroppar. Varje känselkropp tar bara emot information om en slags känselupplevelse, till exempel kyla eller tryck. Det finns känselkroppar i huden, innanför det yttersta hudlagret.

What are receptors?
Receptor may refer to: Sensory receptor, in physiology, any structure which, on receiving environmental stimuli, produces an informative nerve impulse Cell surface receptor, a receptor on the outer surface of a cell membrane, that takes part in communication between the cell and the outside world
What are the receptors of the adrenergic system?
adrenergic r’s receptors for epinephrine or norepinephrine, such as those on effector organs innervated by postganglionic adrenergic fibers of the sympathetic nervous system. There are two types, alpha-adrenergic receptors and beta-adrenergic receptors.
What are alpha and beta adrenergic receptors?
α-r’s (α-adrenergic r’s) alpha-adrenergic receptors. adrenergic r’s receptors for epinephrine or norepinephrine, such as those on effector organs innervated by postganglionic adrenergic fibers of the sympathetic nervous system. There are two types, alpha-adrenergic receptors and beta-adrenergic receptors.
What are the receptors of the cholinergic receptors?
cell-surface receptor membrane receptor. cholinergic r’s membrane receptors on cells of effector organs, innervated by cholinergic nerve fibers and responsive to the acetylcholine secreted by these fibers. There are two types, muscarinic receptors and nicotinic receptors.
