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. [...]

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 [...]
