how does the nervous system send and receive messages?
12126
When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side, called receptors. Receptors are located on the dendrites. Receptors receive and process the message.

The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. The nervous system includes both the Central nervous system and Peripheral nervous system.

Dendrites look like the branches of a tree and receive messages for the cell. Neurons communicate with each other by sending chemicals, called neurotransmitters, across a tiny space, called a synapse, between the axons and dendrites of adjacent neurons. The architecture of the neuron.

The nervous system is the body's main communication system; it gathers, synthesizes, and uses data from the environment. The most basic unit of the nervous system is the neuron, which serves as both a sensor and communicator of internal and external stimuli.

Functions of the nervous system are sensory input, integration, control of muscles and glands, homeostasis, and mental activity. Nerves carry the signals to the brain. Cells comprising the central nervous system and the peripheral nervous system are classified as neural tissue.

Dendrites extend out from the cell body and receive messages from other nerve cells. An axon is a long single fiber that transmits messages from the cell body to the dendrites of other neurons or to other body tissues, such as muscles. ... Myelin insulates the axon and helps nerve signals travel faster and farther.

The basic functions of a neuron These are to: Receive signals (or information). Integrate incoming signals (to determine whether or not the information should be passed along). Communicate signals to target cells (other neurons or muscles or glands).

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.

The nervous system plays a role in nearly every aspect of our health and well-being. It guides everyday activities such as waking up; automatic activities such as breathing; and complex processes such as thinking, reading, remembering, and feeling emotions. The nervous system controls: Brain growth and development.

Nerve Cells. Although the nervous system is very complex, nervous tissue consists of just two basic types of nerve cells: neurons and glial cells. Neurons are the structural and functional units of the nervous system. They transmit electrical signals, called nerve impulses.
1443169
Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuron—another cell. Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.

The neural or nervous system is a complex network of nerve cells or neurons. The nervous system is specialized to carry messages while the endocrine system provides chemical integration through hormones. To better understand the nervous system, one must realize the difference between a neuron and a nerve.

These nerves extend from the central nervous system to the outermost areas of the body. The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment.

The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are more short-lived. Signal transmission in the endocrine system is slow, since hormones must travel through the bloodstream, but the responses tend to last longer.

The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
849998
The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. ... The somatic system consists of nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin.

Neurons are the cells in the brain that send and receive electrical and chemical signals. They are building blocks of your brain, and transmit information to other neurons, muscles, and tissues throughout the body. They allow you to think, feel, move, and comprehend the world around you.
