Nervous system receptors


There are two receptors in the entire nervous system (both autonomic and somatic)

There are two types of cholinergic receptors

Muscarinic receptors are found in postganglionic cholinergic neurons of sympathetic and parasympathetic systems

Nicotinic receptors are found in autonomic ganglia between preganglionic and postganglionic neurons of both sympathetic and parasympathetic neurons

Adrenergic receptors are two

  • α

  • β receptors

Norepinephrine excites mainly alpha receptors but also beta receptors to a lesser extent as well. Epinephrine excites α and β receptors equally

Isopropyl norepinephine a synthetic hormone chemically similar to epinephrine and norepinephine with strong action on β receptors but none on α.
