where are nicotinic receptors found facts, news, stories and more



Nicotinic receptors are a type of neurotransmitter receptor that are activated by the neurotransmitter acetylcholine. These receptors are found in a variety of different locations in the body, including the central nervous system and the peripheral nervous system.In the central nervous system, nicotinic receptors are found in several different brain regions, including the brainstem, thalamus, and cerebellum. They are also found in the spinal cord and are involved in regulating muscle movement and reflexes.In the peripheral nervous system, nicotinic receptors are found in both the sympathetic and parasympathetic nervous systems. In the sympathetic nervous system, they are found in ganglia, which are clusters of nerve cells that are located outside of the brain and spinal cord. In the parasympathetic nervous system, they are found in the terminations of nerve fibers that innervate organs and glands.Nicotinic receptors are also found in the neuromuscular junction, which is the point of communication between nerve cells and muscle cells. These receptors play a crucial role in muscle contraction by transmitting signals from the nerve to the muscle.In addition to the nervous system, nicotinic receptors are also found in other parts of the body, such as the heart, lungs, and blood vessels. They play a role in regulating heart rate, blood pressure, and lung function.Nicotinic receptors have a wide range of physiological effects, including muscle contraction, memory, pain sensation, and addiction. They are also involved in the development of certain neurological and psychiatric disorders, such as Alzheimer's disease, schizophrenia, and nicotine addiction.In conclusion, Nicotinic receptors are a type of neurotransmitter receptor that are activated by the neurotransmitter acetylcholine. They are found in a variety of different locations in the body, including the central nervous system, peripheral nervous system, neuromuscular junction, and other parts of the body such as the heart, lungs and blood vessels.
