What is the role of the neurons in transmitting electrochemical impulses?

Is an inter neuron the same as an association neuron?

Yes, an interneuron and an association neuron refer to the same type of neuron. Interneurons are responsible for transmitting information between sensory neurons and motor neurons, or between other interneurons in the central nervous system. They play a crucial role in integrating and processing information within the nervous system.

What is the role of a dendrite in the neuron?

It receives impulses from other neurons, and then sends those nerve impulses to the body of the cell, where they are added together at the axon hillock, and if they provide a sufficient strength (voltage, potential), an action potential will fire in the output of the neuron, the axon.

What is the relationship between a stimulus and a nerve impulse?

The neuron is the functional portion of the central nervous system, carrying impulses to the designated location. Neurons also have the role of interpreting an impulse, and waiting for a response. Neurons fall under the category of sensory neurons, interneurons and motor neurons.

What is a Short branched extensions that carry impulses to the nerve cell body are called?

Short branched extensions that carry impulses towards the nerve cell body are called dendrites. Dendrites receive incoming signals and transmit them to the cell body, where the information is integrated before being passed on to other neurons. They play a critical role in the communication between neurons within the nervous system.

What is the role of the myelin sheath?

its the movement of neurons in the body that helps ur digestive system

What plays a critical role as a functional junction between neurons?

SYNAPSE

What is most likely to imitate calcium's role in the function of neurons?

Sodium

What is the role of sensory neurons in the breakdown of food?

Beyond being involved in the taste of food, sensory neurons do not have much of a role in breaking down food. The teeth do the grinding and the stomach is where most of the mixing takes place.

What is the role of the neuron?

Neurons are like they brains messengers. The brain figures out what needs to be done and the neurons tell they body to do it.

Which element is most likely to imitate calciums role in the function of neutrons?

There is no real elemental role in the function of neutrons. Did you mean neurons?

What are the parts and functions of a neuron?

A cell that supports the functions of the nervous system by reacting to stimuli and transmitting nerve impulses. A neuron, or nerve cell, is highly specialized and amitotic. The term "amitotic" means that if a neuron is destroyed it cannot be replaced, because neurons do not undergo mitosis. Each neuron consists of three basic parts: a cell body (soma) that contains the nucleus; one or more dendrites, which are short branches off the body that receive incoming impulses; and a single, long axon that carries impulses away from the body and to the next neuron. Nerves consist of bundles of neurons. Cell body In many ways, the cell body is similar to other types of cells. It has a nucleus with at least one nucleolus and contains many of the typical cytoplasmic organelles. It lacks centrioles, however. Because centrioles function in cell division, the fact that neurons lack these organelles is consistent with the amitotic nature of the cell. Dendrites Dendrites and axons are cytoplasmic extensions, or processes, which project from the cell body. They are sometimes referred to as fibers. Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons. The number of dendrites on a neuron varies. They are called afferent processes because they transmit impulses to the neuron cell body. There is only one axon that projects from each cell body. It is usually elongated and because it carries impulses away from the cell body, it is called an efferent process. Axon An axon may have infrequent branches called axon collaterals. Axons and axon collaterals terminate in many short branches or telodendria. The distal ends of the telodendria are slightly enlarged to form synaptic bulbs. Many axons are surrounded by a segmented, white, fatty substance called myelin or the myelin sheath. Myelinated fibers make up the white matter in the central nervous system (CNS), while cell bodies and unmyelinated fibers make the gray matter. The unmyelinated regions between the myelin segments are called the nodes of Ranvier. In the peripheral nervous system, the myelin is produced by Schwann cells. The cytoplasm, nucleus, and outer cell membrane of the Schwann cell form a tight covering around the myelin and around the axon itself at the nodes of Ranvier. This covering is the neurilemma, which plays an important role in the regeneration of nerve fibers. In the central nervous system (CNS), oligodendrocytes produce myelin, but there is no neurilemma, which is why fibers within the CNS do not regenerate. Functionally, neurons are classified as afferent, efferent, or interneurons (association neurons) according to the direction in which they transmit impulses relative to the central nervous system. Afferent, or sensory, neurons carry impulses from peripheral sense receptors to the CNS (see sensory nerve). They usually have long dendrites and relatively short axons. Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands (see motor neuron). Efferent neurons usually have short dendrites and long axons. Interneurons, or association neurons, are located entirely within the CNS in which they form the connecting link between the afferent and efferent neurons. They have short dendrites and may have either a short or long axon. Glial cells Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system. The other type of cell is the glial cell, or neuroglia. The word "neuroglia" means "nerve glue." Neuroglia cells do not conduct nerve impulses, but instead, they support, nourish, and protect the neurons. They are a special type of connective tissue for the nervous system. Glial cells are far more numerous than neurons and, unlike neurons, are capable of mitosis.

What is the electrolyte that plays an important role in the generation of nerve impulses?

Sodium, potassium, and calcium are the important electrolytes involved in nerve impulses
