Definitions &Translations In the central nervous system, the analogous structures are known as tracts. Neurons are sometimes called nerve cells, though this term is potentially misleading since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.Each nerve is a cordlike structure that contains many axons.ithin a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium. The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium.

Physiological Psych 2200 This nervous system is composed of billions of cells, the most essential being the nerve cells or neurons. There are estimated to be as many as 100 billion neurons in our nervous system! A typical neuron has all the parts that any cell would have, and a few specialized structures that set it apart. The main portion of the cell is called the soma or cell body. It contains the nucleus, which in turn contains the genetic material in the form of chromosomes. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body.

Neurons and Nerve Impulses Nerve Cells. Nerve cells or neurons are the basic unit of the nervous system. Nerves send signals among the brain, spinal cord, and other body organs via nerve impulses. A neuron consists of two major parts: a cell body and nerve processes.

- For other uses, see A band. A sarcomere (Greek sarx flesh, meros part) is the basic unit of striated muscle tissue. Skeletal muscles are composed of tubular muscle cells (myocytes called muscle fibers) which are formed in a process known as myogenesis.Muscle fibers are composed of tubular myofibrils.ctin molecules are bound to the Z line, which forms the borders of the sarcomere. Other bands appear when the sarcomere is relaxed. A muscle fiber from a biceps muscle may contain 100,000 sarcomeres.

Neurons, Hormones, and the Brain 1 The single long fiber that extends from the neuron is called an axon. Axons send information to other neurons, to muscle cells, or to gland cells. What we call nerves are bundles of axons coming from many neurons.  Some of these axons have a coating called the myelin sheath.

- 1 Each neuron has a soma, or cell body, which is the central area of the neuron. 2  It contains the nucleus and other structures common to all cells in the body, such as mitochondria.3  The highly branched fibers that reach out from the neuron are called dendritic trees. 4  Each branch is called a dendrite. Each branch is called a dendrite. 2  Dendrites receive information from other neurons or from sense organs. 3  The single long fiber that extends from the neuron is called an axon. 4  Axons send information to other neurons, to muscle cells, or to gland cells. 5  What we call nerves are bundles of axons coming from many neurons.

- One motor neuron (nerve cell) may stimulate a few muscle cells or hundreds of them, depending on the. particular muscle and the work it does. One neuron and all the skeletal muscle cells it stimulates are a. motor unit. When a long threadlike extension of the neuron, called the nerve fiber or axon, reaches the. muscle, it branches into a number of axon terminals, each of which forms junctions with the. sarcolemma of a different muscle cell. These junctions are called neuromuscular (literally, “nerve-. muscle”) junctions.

- Science Videos. Science Main Index. A nerve or neuron is a specialized cell in the body for transmitting nerve impulses. The peripheral nervous system consists of over 100 billion nerve cells. These nerve cells run throughout the body to connect the brain and spinal cord to all other parts of the body. Nerve cells impulses or signals are used to control body muscles and organ, or to sense information from the body. Read on to learn more about nerves, and what they do in your body.

Neuron A neuron (also known as a neurone or nerve cell) is a cell that carries electrical impulses. Neurons are the basic units of the nervous system and its most important part is the brain. Every neuron is made of a cell body (also called a soma), dendrites and an axon. Dendrites and axons are nerve fibres. There are about 86 billion neurons in the human brain, which comprises roughly 10% of all brain cells.

Neurons and Nerve Impulses 1 Neurons contain the same cellular components as other body cells. 2  The central cell body is the largest part of a neuron and contains the neuron's nucleus, associated cytoplasm, and other cell structures. neuron consists of two major parts: Axons and dendrites are bundled together into what are called nerves. These nerves send signals between the brain, spinal cord, and other body organs via nerve impulses. Nerve impulses are received at the neuronal dendrites and are carried along the axon to the terminal branches.

- Nerves use electrical impulses to transmit signals to the brain. The gaps between the nerve endings are called synapses. Edit. Share to: 1  Brain Regeneration: The Holy Grail of Medicine The regeneration of brain cells in brains damaged by disease or injury has long been an elusive goal. neuron is a nerve cell in which, are circular cells that are bundled together known as ganglion. A actual nerve is attached to the nerve cell. There are two types of nerves … ones that travel messages from the brain or to the brain.

- A group of cells working together is called a tissue. Here are some examples of nervous tissue: 1  Gray matter-cells without insulation, tightly packed in your brain and in the inner part of your spinal cord. 2  Gray matter is like an integrated circuit, connecting and processing information.he nervous system is not just built from neurons. There are also cells that don't communicate, but wrap around the neurons to nourish and protect them, called Schwann cells. The organs of the nervous system work together to coordinate body processes.

- A typical neuron has all the parts that any cell would have, and a few specialized structures that set it apart. The main portion of the cell is called the soma or cell body. It contains the nucleus, which in turn contains the genetic material in the form of chromosomes. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons. One extension is different from all the others, and is called the axon. Although in some neurons, it is hard to distinguish from the dendrites, in others it is easily distinguished by its length. The purpose of the axon is to transmit an electro-chemical signal to other neurons, sometimes over a considerable distance.
