Synthesis of Catecholamines | Nervous System |Animals

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 [...]

Classification of Antiadrenergic Drugs | Pharmacology | Animals

After reading this article we will learn about the classification of antiadrenergic drugs These are the drugs which antagonize the pharmacological action of sympathomimetic agents or alter the function of sympathetic nervous system inside the body. Classification: On the basis of mechanism of action. 1. α-Adrenoceptor Antagonists: Phenoxy-benzamine: (i) Phenoxy-benzamine is a halo-alkyl-amine. It binds covalently to the α receptors [...]

Sympathetic and Parasympathetic Nerve Fibres | Pharmacology

This article will help you to differentiate between sympathetic and parasympathetic nerve fibres. Difference # Sympathetic Nerve Fibre: 1. They arise from thoraco-lumber (T1 to L3) region of the spinal cord. 2. Ganglia are nearer to CNS. The ratio of pre and postganglionic fibres is generally 1: 20 or more. So, the post ganglionic fibers are longer. 3. Neurotransmitters are [...]
