Neurotransmitters. With the regard to the process of the neural transmission, a refractory period refers to the time in interval in which. the Positively charged sodium ions are to pumped back to outside a neural membrane.

Neurotransmitters are the chemical messengers that your body can't function without it. Their job is to carry out chemical signals (“messages”) from one of the neuron (nerve cell) to the next target cell. The next target of the cell can be another nerve cell, a muscle cell or the gland.

Fortunately, the seven “small molecule” are neurotransmitters (acetylcholine, dopamine, the gamma-aminobutyric acid (GABA), or glutamate, histamine, norepinephrine, and the serotonin) do the majority of the work.

What are the benefits of cell division in somatic cells?

AlexFokin [52]

Answer:

Somatic cells helps in healing and repairing damaged cells

Explanation:

Somatic cell division plays an important role in division of body cells. They help in healing and repairing the damaged cells. cell division is of two types, Mitosis and meiosis. Mitosis replicates and results in two identical daughter nuclei (genetically identical). Apart from these, they also act as adult stem cells which plays a major role in healing the damaged cells or repair the damaged cells. somatic cells are found all over your body except the germ cells.

Benefits of cell division in somatic cells:

If you get hurt and eventually your blood will stop oozing out and get healed by the mitotic cell division found in the somatic regions of your body.
Animals like lizards when get hurt, they get their cells automatically repaired by their somatic cells.

These are few important benefits other than the identical copies that are obtained by cell division.

<h3>What is the use of spines in animals?</h3>

Spines are hard, needle-like anatomical structures found in both vertebrate and invertebrate species.
The spines of most spiny mammals are modified hairs, with a spongy center covered in a thick, hard layer of keratin and a sharp tip.
Spines on an animal’s body help defend it.
They can be irritating or painful, or difficult to swallow.
Spines are also important tools for communication, shock absorption, and rain protection.
Animals like porcupine shoot their spines (quills) for defense. Some spines can also pass through gloves.
To prevent attacked by an animal with poisonous spines you must remain calm and observe your surroundings.
