What are the applications of human nervous cells?
Andreyy89

The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process. The human brain has approximately 86 billion neurons. To learn how neurons carry messages, read about the action potential.

Neurons come in many different shapes and sizes. Some of the smallest neurons have cell bodies that are only 4 microns wide. Some of the biggest neurons have cell bodies that are 100 microns wide. (Remember that 1 micron is equal to one thousandth of a millimeter!).

Neurons are similar to other cells in the body because:

Neurons are surrounded by a cell membrane.

Neurons have a nucleus that contains genes.

Neurons contain cytoplasm, mitochondria and other organelles.

Neurons carry out basic cellular processes such as protein synthesis and energy production.

However, neurons differ from other cells in the body because:

Neurons have specialize cell parts called dendrites and axons. Dendrites bring electrical signals to the cell body and axons take information away from the cell body.

Neurons communicate with each other through an electrochemical process.

Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters).

The Neuron

neuron

One way to classify neurons is by the number of extensions that extend from the neuron's cell body (soma).

bipolar neuron

Bipolar neurons have two processes extending from the cell body (examples: retinal cells, olfactory epithelium cells).

Pseudounipolar cells (example: dorsal root ganglion cells). Actually, these cells have 2 axons rather than an axon and dendrite. One axon extends centrally toward the spinal cord, the other axon extends toward the skin or muscle.

Multipolar neurons have many processes that extend from the cell body. However, each neuron has only one axon (examples: spinal motor neurons, pyramidal neurons, Purkinje cells).

Neurons can also be classified by the direction that they send information.

Sensory (or afferent) neurons: send information from sensory receptors (e.g., in skin, eyes, nose, tongue, ears) TOWARD the central nervous system.

Motor (or efferent) neurons: send information AWAY from the central nervous system to muscles or glands.

Interneurons: send information between sensory neurons and motor neurons. Most interneurons are located in the central nervous system.

Check out the Gallery of Neurons to see some pictures of real neurons or "Sidewalk Cells" to see photographs of neurons on the street.

"Neuron" | "Axon" | "Dendrite" |

"Nissl" | "Mitochondria" | "Endoplasmic reticulum"

There are several differences between axons and dendrites:

Which of the following materials is not part of every chemical reaction?
Sladkaya [172]

Answer:

The correct answer is C. gases.

Chemical reaction is the process by which one or more substances are converted into different substance or substances.

The substances which undergo chemical reaction are called as reactants while the substances which are produced by the reaction are called as products. During chemical reaction, chemical bonds of substrates undergo breaking and formation process to form an entire new product which may have same or different physical and chemical properties as compared to substrates.

Energy is either used or released during the chemical reaction. When the energy is used, it is termed as endothermic reaction but when the energy is produced by the reaction, it is termed as exothermic reaction.

Lastly, gases may or may not participate in a chemical reaction.
