Peripheral nervous system | sympathetic and parasympathetic nervous system | Class 12 Biology

About This Video ........................ In This Video Lecture You Will Learn Basic Concept Of Peripheral Nervous System It comprises of sensory neurons and motor neurons, which may form ganglia and the nerves. upon the direction of impulse they conduct. In humans, there are 12 pairs of nerves, which arise these nerves are sensory, some motor, and are mixed. From the spinal cord 31 pairs of spinal nerves arise or lead to spinal cord. All these nerves are mixed having fibres of both sensory and dendrites, bounded by connective tissue. They may be sensory motor or mixed nerves depending Ganglia are the concentrations of cell bodies of neurons. The nerves are the bundles of axons or from the brain, or lead to the brain. These nerves are called cerebral or cranial nerves. Some of motor neurons. Motor neurons form somatic nervous system, which controls voluntary movements, which are under the conscious control of the body, involving skeletal muscles. Motor neurons also form and smooth muscles. The autonomic nervous system is further divided into sympathetic nervous autonomic nervous system, which controls involuntary responses by inluencing organs, glands system and para sympathetic nervous system. About This Channel..................... I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources. One-stop destination for all biology lectures. _ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial _ The videos are categories under various heading to make the students life simplified Visit My Other Channel Playlist .....................
