Answer:

The correct option is A. Polycythemia Vera

Explanation:

Polycythemia vera is a myeloproliferative disorder of bone marrow hematopoietic cells that causes excessive production of all types of blood cells.

Primary erythrocytosis occurs as a result of polycythemia vera, in this myeloproliferative disorder the bone marrow produces too many red blood cells along with excessive amounts of white blood cells and platelets. Bone marrow under normal conditions produces blood cells and contains the precursor cells of the three series: red blood cells, white blood cells or leukocytes and platelets or thrombocytes, this disorder is characterized by excessive or uncontrolled proliferation or growth of these cells. The increased production of red blood cells or erythrocytes is called erythrocytosis.

Answer:

A) Polycythemia Vera

Explanation:

Erythrocytosis refers to a condition of the blood in which the count of the Red blood cell in the blood increases due to abnormal proliferation of the red blood cells.

The main cause of the primary erythrocytosis is caused by a disease called polycythemia Vera in which the stem cell starts producing a large number of a red blood cell.

The increased number of the red blood cell leads to the thickening of the blood which lowers the flow of the blood in the body and the formation of blood clots.

Thus, Option-A is the correct answer.

The vibrations are sent to the bones of the MIDDLE EAR where they are amplified, and passed to a structure called COCHLEA in the INNER EAR.

Finally, it reaches the sensory cells that passes it to the auditory nerve that transmit the sound to the brain as electrical signals (neural messages) for proper interpretation.

So, it is True because from OUTER EAR to MIDDLE EAR, to INNER EAR.

Ahat [919]

Answer:d) contracting her pupils and increasing secretion of stress hormones.

Explanation:

Peripheral nervous system consists of 3 major neuronal levels: vegetative (reticular formation and brain stem), limbic system and neocortical level. The RAS is the link between the brain and the spinal cord.

Brain stem consists of pons, medulla oblongata and mesencephalon. Brain stem is responsible for involuntary functions such as heart beat, respiration and vasomotor activity. Limbic system represents the emotional control center. It consists of thalamus, hypothalamus and pituitary gland and maintains homeostasis. Neocortical part processes sensory information and regulates emotional responses.

Autonomic nervous system (ANS) regulates visceral activities and organs (circulation, digestion, respiration and temperature). ANS has two divisions: sympathetic and parasympathetic nervous system.Parasympathetic nervous system regulates homeostasis via the release of acetylcholine (Ach). Parasympathetic nervous system is responsible for energy conservation and relaxation.

There are three stages in the stress response: immediate effects of stress, intermediate effects of stress and prolonged effects of stress.
