Get the answer of: What are Adrenergic Drugs? These are the drugs that mimic the actions of the sympathetic nervous system. Their effects are mediated by the adrenergic receptors on the effector cells, hence these are also called as adrenergic drugs. Classification of Adrenergic Drugs: (A) On the Basis of Mechanism of Action: Direct acting drugs act directly on adrenergic [...]
This article will help you to differentiate between autonomic and somatic efferent pathways. Difference # Autonomic: 1. Two neurons (pre and postganglionic) are arranged in series to supply smooth muscles and glands. 2. The autonomic nerves contain peripheral ganglia. 3. Preganglionic nerves are myelinated and postganglionic nerves are non-myelinated. 4. Some level of spontaneous activity of an organ is maintained [...]
After reading this article you will learn about the synthesis of catecholamines. Norepinephrine (NE) or noradrenaline (NA) is the main transmitter at sympathetic neuro-effector junctions (except sweat glands and hair follicles) and CNS. Other neurotransmitters related to adrenergic transmission are dopamine (predominant in brain) and epinephrine (secreted by adrenal medulla). They are commonly named as catecholamines due to presence of [...]
