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 musÂcles 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 [...]
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 [...]
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.
