The nervous system function is one complex and tremendously organized body system. It coordinates the action and sensory information. This information is received from different organs and is transmitted via nerves through the spinal cord. It is then processed by the brain and the nervous system structure is spread around the whole body to function suitably. This system directs the body’s function and controls our reaction to the outside world. It’s like a hyperactive connection that sends signals, electrical and chemical in lighting speed between cells. One should consult a famous neurologist in Patna in case any damage is caused to the nervous system.
Given below are some interesting nervous system facts and functions.
Nervous system facts A-Z:
The two main nervous systems
The nervous system includes the brain and spinal cord as the central nervous system. The peripheral nervous system includes nerves and sensory organs. Together with the help of CNS and PNS, it transfers sensory information, and along with that, it coordinates body functions. Sensory organs send data to the brain and spinal cord (CNS) from the nerves throughout the body. The CNS is the control center that processes this information and sends the command back. The nerves carry out the signals that are outgoing and incoming. Any damage to these nervous systems may require the help of a brain doctor in Patna for a quick recovery.
The Neurotransmitter effect
A neurotransmitter is a chemical that is released when signals reach the end of the neuron. The message passes through neurons as electrical signals, and they facilitate the release of this chemical. It travels between neuron spaces and even other body tissues or cells. It has two types: excitatory and inhibitory. Excitatory neurotransmitters enable the electrical signal in neurons that encourage responses from body cells. On the other hand, an inhibitory transmitter discourages these signals and cellular responses. These chemicals assist in controlling the activities of muscles, glands, and nerve pathways. If you suspect any malfunction of the muscles or other body parts, consult the best neurologist in Saket.
The nerve branches of the nervous system
The nervous tissue from the brain to the spinal cord and further nerve trunk includes cells called neurons. Neurons are charged cells as they conduct electrical signals to pass information throughout the body. A basic neuron consists of a dendrite, axon, and axon terminal. Body tissues or neurons pass signals to dendrite, and it is transmitted into the cell body. An outgoing signal is zipped in the axon and passed ahead through the axon terminal to the targeted cell. It has a huge capacity to send a signal from the nerve pathway and via the central nervous system too. One should consult the best neurologist in Gwalior or the famous neurologist in Gwalior, Dr. Chandril Chugh for proper treatment of damaged nerves. You can also find him as a neurologist in Punjab, the best neurologist in Faridabad or brain specialist doctor in Faridabad, a top neurologist in Jaipur or neurologist doctor in Jaipur, the best neurologist in Saket, best neurologist in South delhi, neurologist in Agra, mind doctor in Delhi, top neuro physician in Patna and a top neurologist in Gwalior or neurologist doctor in Gwalior. He is also amongst the top 5 neurologist in Patna. You can also go for neurologist online chat or online neurologist consultation.
The roadway of nerves
The spinal cord is covered up by connective tissues and bones. It’s made up of neuron cells and a stack of axons. The brain’s medulla oblongata is connected down to the vertebral column. It’s a super track and part of the CNS. It enhances the nervous system factors of sensory information that motors command up and down to and from the brain. These signals speed in and out via spinal nerves. The spinal cord can pass on a reflex command without including the brain responses.
The brain- the engine of the body
This Nervous system organ connects perceptions and memory. Passing information might be the basic process command of the nervous system, but when you smell a familiar perfume do you feel nostalgic? It happens because of the limbic system that forms two rings paired within the brain. It consists of the amygdala, the hippocampus, the cingulate gyrus, and the dentate gyrus. The limbic system is involved in different nervous system function that helps our memory, olfaction (Our sense of smell) and even our range of emotions. The aroma that makes you happy and you reach out to the meal is the collective work of the limbic system.
Neurons can look different
While one may assume that all neurons look the same, it’s not true. Neurons have different sizes and shapes depends upon their location in the body and their functionality. Sensory neurons are connected by a long axon with dendrites on both ends and a cell body in middle. Whereas, motor neurons have a long axon in the middle. A cell body and dendrites on each end.
Two types of the nervous system
The voluntary and non-voluntary nervous system exists in the body along with PNS and CNS. The voluntary system controls action that a human being is aware of and even control consciously, like moving head, legs, arms, and different body parts. The other system controls the processes that the body can’t control consciously. The system is always active and governs an individual’s breathing, heartbeat rate, metabolism, and other critical body processes. One may get an online neurologist consultation if they experience any trouble in their routine bodily processes.
A nervous system prepares the body for action
The sympathetic nervous system notifies the body to get active for physical and any mental activities to face them. When the body is active, it makes breathing easy, and the heartbeat faster. Even the digestion in the body is temporarily stopped due to this system and activeness load. Seek guidance from a neurologist in south Delhi for the treatment of neurological disorders.
Controlling the body at rest
The sympathetic nervous system facts were referring to activating the body for work. On the other hand, the parasympathetic nervous system restraint body function when it is at rest. It includes activating metabolism, stimulating digestion, and settling the body in a relaxed state.
The handler of bowel movement
The bowel movements in our body are controlled by the enteric nervous system. It automatically regulates bowel movements as a part of digestion. Consult the top best neurologist in Jaipur if you face troubles with passing bowels
The different types of neurons
Neurons have four types:
- Motor: Motor neurons are the ones that carry signals from the central nervous system to the outside parts of the body.
- Sensory: Sensory neurons carry the signals into the central nervous system from the outer part of the body – the glands, muscles, and skin.
- Receptors: Receptors sense the surrounding environment like light, sound, touch, and chemicals around you. Further, it converts into electrochemical energy and is sent by sensory neurons.
- Interneurons: This neuron is promised to send messages from one neuron to another one.
The loss of neurons
Neurons too have a lifespan. We start losing our neurons at around 20 years of age and till we reach the age of 75, 1/10 of our neurons are gone by the age of 75.
