Classification of Central Transmitters | Pharmacology

The transmitters, central or peripheral, may be conveniently classified into two categories: 1. Non-peptide transmitter with molecular weight less than 200. These include amines and amino acids. The amines include acetylcholine (a tertiary amine) and biogenic amines e.g. dopamine, serotonin (5-HT), norepinephrine, epinephrine and histamine. The amino acids include glycine and GABA (monocarboxylic; inhibitory), and glutamate/aspartate (dicarboxylic; excitatory), and 2. [...]

Synthesis of Acetylcholine | Nervous System | Animals

After reading this article we will learn about the synthesis of Acetylcholine (Ach).   Acetylcholine (Ach) is the neurotransmitter at parasympathetic neuro-effector junctions, all autonomic ganglia, adrenal medulla, somatic neuromuscular junctions, and CNS. Synthesis, Storage and Release of Ach: Ach is synthesized in the cholinergic nerve endings. After a reaction among acetate, coenzyme A and ATP, acetyl CoA is formed within [...]

Autonomic and Somatic Efferent Pathways | Animals | Pharmacology

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 [...]
