Sympathetic nervous system | Autonomic nervous system | Nervous system - pharmacology This video is all about the sympathetic nervous system. the sympathetic nervous system along with the parasympathetic nervous system is divisions of the autonomic nervous system. the autonomic nervous system and somatic nervous system mutually are called the peripheral nervous system. and this peripheral nervous system is the division of our nervous system along with the central nervous system. the sympathetic nervous system prepares us for energy expending, stressful and emergency situations as well as prepares us for doing exercise. the sympathetic division is also known as "the fight or flight response" and "thoracolumbar division" the sympathetic nervous system innervates many organs of our body like eyes, salivary glands, heart, lungs, spleen, stomach, small and large intestines, kidneys, adrenal gland, urinary bladder, and reproductive organs. the sympathetic may activate or inhibit the functions of the organs depending upon the organ and the receptors on that organ. COVERED TOPICS 1. Autonomic nervous system 1.1 Sympathetic nervous system aka thoracolumbar division & fight or flight response 1.2.1 Organs innervated by the sympathetic nervous system discussed in this video are 1.2.1 eye 1.2.2 salivary glands 1.2.3 heart 1.2.4 lungs 1.2.5 spleen 1.2.6 stomach 1.2.7 small and large intestines 1.2.8 kidneys 1.2.9 adrenal gland 1.2.10 urinary bladder 1.2.12 reproductive organs 1.3 how these above organs respond when are get sympathetic impulses 1.4 general discussion on the preganglionic and postganglionic fibres of sympathetic division.

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.

Nervous system | Neuron Structure This video is all about the neuron. 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. Soma is the biosynthetic centre and contains the neuroplasm and other important organelles require for normal functioning of the neuron, while the dendrites and axon also contain some organelles like the soma and these structures are involved in the transmission of the impulses. Sometimes the axon has a protective cover called the Myelin sheath, produced by the Schwann cells.

keywords: nervous system, cerebrum, lobes, hemispheres, functional regions, motor area, sulcus, gyrus, The nervous system is the control centre of all the functions either voluntary or involuntary, of our body. it has two main divisions the central nervous system and the peripheral nervous system. the central nervous system is composed of the brain and spinal cord, while the peripheral nervous system consists of neurons located outside the central nervous system. the cerebrum is the largest part of the brain and controls most of the voluntary movements with addition to the sensor and association functions. This video is all about the anatomical and physiological divisions of the cerebrum, hemispheres of the cerebrum, lobes of the cerebrum like frontal, parietal, temporal and occipital lobes. the cerebrum also consists of grey matter and white matter which is all discussed in the video. the cerebrum is also divided on the basis of its functional divisions as sensory areas, association areas, and motor areas. and these areas are scattered throughout the cerebral cortex.

This video is all about the nervous system’s divisions. The nervous system is the control centre of our body and it controls the function either voluntary or involuntary. The nervous system can be divided and subdivided into many divisions on the basis of anatomy or physiology. The nervous system is divided into two main divisions: the central nervous system and peripheral nervous system. The central nervous system is further divided into the brain and the spinal cord.

The main part of the nervous system is the brain which is the control centre of the nervous system. The brain has many divisions for example the forebrain, the midbrain, and the hindbrain while further each of them is subdivided into different parts and division. At the lower level, we have different parts of the brain for example cerebrum (which is further divided into various lobes like frontal lobe, parietal lobe, temporal lobe, and occipital lobe), cerebellum, midbrain, pons, and medulla oblongata. While the midbrain, pons, and medulla oblongata is collectively called the brain stem. The spinal cord is also a part of the central nervous system and helps in the communication between the brain and the peripheral nervous system.

The peripheral nervous system comprised of neurons that are outside of the central nervous system and transfer the signals from the central nervous system to the periphery or vice versa. The peripheral nervous system is further divided into two main divisions that are somatic nervous system and autonomic nervous system.
