I would say it would respond w/ it hurting and your gasping for air because when you run for a long periods of time u get a pain that hurt from running so much and because your dehydrated and ran out of breath

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.

There are several differences between axons and dendrites:

How is the process of photosynthesis taking place thru Calvin Cycle?
Juli2301 [7.4K]

This is the ideal question! Thanks for asking!

Before we start, let's go through a mini-review.

Photosynthesis:

The complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.

Calvin Cycle:

A series of biochemical reactions that take place in the stroma of chloroplast in photosynthetic organisms.

Now that we have gone through what these two terms are and their definitions, let's head onto the actual questions.

So the question asks, how is the process of photosynthesis taking place through Calvin Cycle?

In plants, carbon dioxide (CO2CO2CO2​C, O, start subscript, 2, end subscript)  enters the interior of a leaf via pores called stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions, where sugar is synthesized. Because they are not primarily fueled by light, these reactions are often known as the "light-independent reactions."

Carbon atoms from CO2 CO2 CO2 C, O, start subscript, 2, and end subscript are fixed (incorporated into organic molecules) and utilized to create three-carbon sugars in the Calvin cycle. ATP and NADPH produced by the light reactions are used to power and support this activity. Calvin cycle reactions occur in the stroma, as opposed to light reactions, which occur in the thylakoid membrane (the inner space of chloroplasts).

That's about it! If you'd like, check out the attachment for a visual!

Thank you,
