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 [...]

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 [...]

Autonomic Nervous System (ANS)

After reading this article you will learn about the anatomy and physiology of Autonomic Nervous System (ANS). Various body activities are controlled by the nervous system. This is achieved by controlling the contraction of skeletal muscles throughout the body, contraction of smooth muscles in the organs, and secretion of both exocrine and endocrine glands in many parts of the body. [...]
