Which atmospheric layer gets warmer as altitude increases?

lesya692 [45]

Answer:

Muscles contract through a chain process of electrochemical signalling between the nervous system and muscles.

Explanation:

The muscle contraction is initiated by the nervous system by sending a signal. This signal also referred to as action potential travel through the motor neuron. This motor neuron releases a chemical signal to muscle when the electrical signal carried by it reaches the neuromuscular junction (a junction where motor neuron meets the muscles).

The chemical message referred to as neurotransmitter binds to the receptors present on the muscle fibers. These receptors causes the influx of sodium ion which in turn trigger the release of calcium ion thereby initiating the contraction of muscles.

Answer:

I am a basophil.

Further information:

Basophil:

Basophils are a type of white blood cell. Basophils are the smallest common of the granulocytes, representing about 0.5 to 1% of circulating white blood cells. Yet, they are the major type of granulocyte.

Function of basophil:

They are accountable for inflammatory reactions during immune response, as well as in the development of acute and chronic allergic diseases, including anaphylaxis, asthma, atopic dermatitis and hay fever. They also yield compounds those co-ordinate immune responses, including histamine and serotonin that induce inflammation, heparin that stops blood clotting, although there are less than that found in mast cell granules.

Basophils may present in many specific types of inflammatory reactions, specially those that cause allergic symptoms. Basophils have anticoagulant heparin, which prevents blood from clotting too rapidly. They also have the vasodilator histamine, which promotes blood flow to tissues.

Structure of Basophil:

Basophils comprise large cytoplasmic granules which vague the cell nucleus under the microscope when stained. However, when unspotted, the nucleus is visible and it usually has two lobes. The Mast cell which is another granulocyte has very like in appearance and function. Both cell types store histamine, a chemical that is secreted by the cells when inspired. However, they arise from different branches of hematopoiesis, and mast cells usually do not circulate in the blood stream, but instead are located in connective tissue. Similar to all circulating granulocytes, basophils can be carried out of the blood into a tissue when we need it.
