what are the chemical messengers for the nervous system?
479979
Neurotransmitters are often referred to as the body's chemical messengers. They are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles.

The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. ... The central nervous system (CNS) includes the nerves in the brain and spinal cord.

what are 2 advantages of having a nervous system? Nervous system helps our various body parts to communicate with each other. It enable us to quickly detect a stimulus and then communicate and co ordinate accordingly with external as well as with internal environment to make an appropriate response.

Neurotransmitters are messengers, such as dopamine.

Humans have two types of communication systems. These are the nervous system and the endocrine (hormone) system. These systems regulate body processes through chemical and electrical signals that pass between cells. The pathways for this communication are different for each system.

There are many major and minor signalling chemicals in the brain. The major neurotransmitters in your brain include glutamate and GABA, the main excitatory and inhibitory neurotransmitters respectively, as well as neuromodulators including chemicals such as dopamine, serotonin, norepinephrine and acetylcholine.

The nervous system uses blood-borne chemical messengers called hormones. The nervous system controls immediate, short-term processes, whereas the endocrine system controls daily maintenance of processes that go on for long periods of time.

The nervous system includes the brain, nerves and spinal cord. It is the communication center for the body, sending and receiving messages, regulating body functions and serving as the control center for the five senses and for emotions, speech, coordination, balance, and learning.

Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system.

There are two broad classes of cells in the nervous system: neurons, which process information, and glia, which provide the neurons with mechanical and metabolic support. Three general categories of neurons are commonly recognized (Peters, Palay, & Webster, 1976).

At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body. It does this by extracting information from the environment using sensory receptors. This sensory input is sent to the central nervous system, which determines an appropriate response.

What are the General Functions of the Nervous System? To maintain body homeostasis with electrical signals, provide for sensation, higher mental functioning, and emotion response, and activate muscles and glands. Central nervous system and Peripheral nervous system.

['Receive signals: Nerves receive signals because they are irritable, meaning that they can respond to a stimulus. ... ', 'Transmit nerve impulses: Nerves are able to transmit impulses along the length of the nerve cell in the form of an electrical signal (like power lines).']

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.
