Whats wrong with timothy a case study on the endocrine system answers?

1. Timothy's symptoms are loss of coordination and stamina, sudden increase in growth rate, painful joints, nausea, worse school performance (probably cognitive decline) and changes in personality, such as depressive mood, introversion, anxiety and tension. The organ system which could be implicated in these deficits is the thyroid gland, an important part of the human endocrine system

2. The thyroid gland is an endocrine gland located in the neck, behind Adam's apple. It produces two thyroid hormones, thyroxine and triiodothyronine, and calcitonin. The thyroid gland is a very important regulator of metabolism, protein synthesis and development. In particular, thyroid hormones regulate the body's metabolism, by controlling the way the cells produce and consume energy.

3. Hyperthyroidism is an endocrine condition in which the thyroid gland produces an excessive amount of thyroid hormones. It is the case of an overactive thyroid and its main symptom is the acceleration of the metabolism. Timothy's symptoms that could suggest hyperthyroidism are his sudden increase of growth rate and inability to gain weight, his nervousness and mood changes, and his fatigue or loss of energy.

4. Cortisol is a steroid hormone that is produced by the adrenal gland. It is considered the body's stress hormone, as it is released in response to a stressor. It is also produced in response to low blood-glucose concentration. Some of its functions are the increase of blood sugar and the suppression of the immune system and bone formation. Cortisol is also involved in the metabolism of macronutrients.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
