Cholinergic receptors | Muscarinic and Nicotinic receptors - Pharmacology

Cholinergic receptors | Muscarinic and Nicotinic receptors - Pharmacology This video is all about the Cholinergic receptors ( Cholinoceptors ) and their subtypes. cholinergic receptors are those receptors to which neurotransmitter acetylcholine binds and show its pharmacological action. these cholinergic receptors are found mainly in the Nervous system but also present throughout the body and they are concerned with different functions in our body, which is all discussed in this video. cholinergic receptor ( cholinoceptors ) are mainly divided into two classes is the muscarinic receptors and nicotinic receptors, based on their affinity for different agonists to which these receptors respond. for example, the muscarinic receptors have a high affinity for muscarine beside acetylcholine while the nicotinic receptors have a high affinity for nicotine beside acetylcholine. nicotine is an alkaloid of tobacco. muscarine also binds to nicotinic but have a low affinity and same is the case with nicotine which can also bind to muscarinic receptors but have a low affinity for it. The muscarinic receptors are further divided into the M1 ( neuronal muscarinic receptors ), M2 ( cardiac muscarinic receptors ), M3 ( smooth and glandular muscarinic receptors ), M4 and M5 receptors. The nicotinic receptors are also divided into neuronal nicotinic or Nn receptors and Neuromuscular nicotinic or Nm receptors. COVERED TOPICS: 1.

Sympathetic nervous system vs parasympathetic nervous system | Autonomic nervous system - Pharmacology In this video lecture we have discussed the main differences between the sympathetic nervous system and the parasympathetic nervous system. the sympathetic nervous system and the parasympathetic nervous system are two main divisions of the autonomic nervous system. the sympathetic system is also known as the fight or flight response and prepare us for stressful and emergency situations, as well as for exercise. in contrast, the parasympathetic nervous system is known as the rest and digest response. parasympathetic response predominate the sympathetic nervous system in situation like when we are eating or lying down. For more knowledge about the sympathetic, parasympathetic and autonomic nervous system watch our previous videos on these nervous system divisions.

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

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.
