Which gland produces T3 and T4?
Leokris [45]

Answer:

<em>1. The gland that produces T3 and T4 is the </em><em>thyroid</em><em> (first option). </em>

<em>2. True. The </em><em>adrenal gland</em><em> produces and allows the secretion of the hormone involved in the fight and flight response. </em>

<em>3.The symptom that is not correctly matched with the organ system is joint pain, which is related to the joint system, not the skeletal system.</em>

<em>4. False. </em><em>Negative feedback loop</em><em> inhibits the production and release of hormones.The symptom that is not correctly matched with the organ system is Joint pain - skeletal system</em>

Explanation:

1. Thyroid gland is a small organ of no more than 30 grams found in the neck, in front of the trachea. This gland produces thyroglobulin, which when joined with iodine can synthesize triiodoythyronine (T3) or thyroxine (T4).

The main function of the thyroid gland is the regulation of organic metabolism, while it can also mediate the body's response to other hormones.

2. Adrenal gland is located in the upper pole of each kidney and is responsible for the secretion of several substances that help with the body's activity.

In the gland's marrow, a substance called adenaline is produced, with properties such as hormone and neurotransmitter, one of the main substances produced to deal with stress and the adaptation response called fight and flight.

The adrenaline produced in the adrenal medulla can strengthen muscles, increase heart rate and blood pressure, and increase the body's resistance to the presence of stressors or threats to physical integrity.

3. Joint pain is related to inflammation of the joint soft tissues, which belong to the joint system. Unlike joint pain, bone pain occurs as a result of injury to the periosteum -the thin membrane that covers the bones- which is related to the skeletal system.

Painful inflammation of the joints is called arthritis, and is one of the main causes of disability to perform normal body movements.

4. <u>Feedback is a control mechanism of the endocrine system</u>. Negative feedback loop occurs in response to a stimulus, resulting in the inhibition of mechanisms that promote the synthesis and release of substances.

An example of negative feedback is the sufficient production of thyroid hormones, which sends a signal to the hypothalamus, which in turn inhibits the production of TSH - thyroid stimulating hormone - at the level of the pituitary gland. If the pituitary does not release TSH, production of thyroid hormones ceases.
