Our nervous system is mainly divided into two divisions: the Centeral nervous system and peripheral nervous system. The central nervous system or CNS include Brain and spinal cord, while the peripheral nervous system or PNS is further divided into the somatic and autonomic nervous system or ANS. Autonomic nervous system or ANS controls all the involuntary functions of our body and concerned with the functions of visceral body parts and innervate smooth muscles, cardiac muscles and glands. This system act autonomously and continuously without the conscious control. For example this division controls Heart activities, GIT motility and secretions, Glands secretions, pupil size, energy metabolism, lungs airways diameter, etc. Covered Topics In this video we have generally discussed the autonomic nervous system, their pathway, autonomic Centers, divisions of ANS that is sympathetic nervous system and parasympathetic nervous system, neurons of ANS that is preganglionic neurons and postganglionic neurons and lastly the organs that are innervated by the autonomic nervous system for example Heart, stomach, GIT, liver, eyes, smooth muscles, pancreas, blood vessels, sweat gland, hair follicles, urinary bladder, spleen, etc

Classification of neurons | Nervous system This video is all about the classification of neurons. The neuron is the structural and functional unit of the nervous system. Neurons greatly vary structurally but all have some structures in common, that is the soma or cell body, dendrites and axon. neurons can be divided based on structure, function, and myelin sheath. based on structure, we have multipolar, unipolar, and bipolar neurons. while functionally neurons are divided as sensory neurons. association or interneurons, and motor neurons. while another classification is based on myelin sheath and we have myelinated and unmyelinated neurons under this heading. besides, most of the neurons supplying specific organs or tissues are named differently. for example, motor neurons to the skeletal muscles are called somatic while neurons innervating the internal visceral organs are called visceral motor neurons and form the autonomic division.
