Dopaminergic

Back 5

Releasing dopamime as a neurotransmitter

releasing or involving dopamine as a neurotransmitter. Drugs with this effect are used in the treatment of Parkinson's disease and some psychiatric disorders; some are subject to abuse.

Front 6

sympathomimetic drugs

Back 6

(it both raises blood pressure and dilates bronchi)

Front 7

Sympathetic agonist

(S)

Back 7

The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine), which function as both neurotransmitters and hormones.

Front 8

Fight-or-flight response(S)

Back 8

also called hyperarousal, or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. It was first described by Walter Bradford Cannon.

Back 10

It consists of nerves arising from the brain and the lower end of the spinal cord and supplying the internal organs, blood vessels, and glands.

Front 11

Acetylcholines

Back 11

neurotransmitter used at the neuromuscular junction—in other words, it is the chemical that motor neurons of the nervous system release in order to activate muscles. This property means that drugs that affect cholinergic systems can have very dangerous effects ranging from paralysis to convulsions.

Front 12

nicotinic receptor(P)

Back 12

The nicotinic receptor is a channel protein that, upon binding by acetylcholine, opens to allow diffusion of cations. The muscarinic receptor, on the other hand, is a membrane protein; upon stimulation by neurotransmitter, it causes the opening of ion channels indirectly, through a second messenger.

methacholine chloride. Clinical Pharmacology: Mechanism of Action: A cholinergic, parasympathomimetic, synthetic analog of acetylcholine that stimulates muscarinic, postganglionic parasympathetic receptors. Therapeutic Effect: Results in smooth muscle contraction of the airways and increased tracheobronchial secretions ...

block is essentially a unilateral block of the spinal nerve, including the dorsal and ventral rami, as well as the sympathetic chain ganglion. These blocks can be performed at any vertebral level. However, they are most commonly performed at the thoracic level because of anatomic considerations.
