has no thyroid gland? Rat A (1 pts) 2. Justify your answer. (what data convinced you of your answer) (1 pts) T3 and T4 regulate the metabolism‚ so when more is available it increases the baseline metabolic rate. TSH causes the release of T3 and T4‚ so if the rat is injected with TSH‚ in theory we would suggest that the levels of T3 and T4 are also higher than the baseline metabolic rate. 3. In a further experiment‚ all 3 rats were given a drug that inhibits the production of thyroid hormone

help the body carry out many of its functions. This system regulates our mood‚ growth‚ metabolism‚ tissue development‚ sexual functions and reproductive process. The endocrine system is made of a series of glands that produce chemicals called hormones. Like many medical terms‚ it originates from the Greek words "endo" meaning inside‚ within‚ and "crinis" for secrete. The endocrine system is an information signal system similar to the nervous system‚ yet its effects and mechanisms are different

The most common conditions that an endocrinologist treats would be menopause‚ diabetes‚ thyroid diseases‚ metabolic disorders‚ lack of growth‚ over-or under-production of hormones‚ osteoporosis‚ cancers of the endocrine glands‚ cholesterol disorders‚ hypertension‚ and infertility. They do a variety of research to find more improved ways to treat abnormal hormonal imbalances. To become

many effects on the tissues and organs. The thyroid gland‚ which is a part of the endocrine system‚ releases a hormone that maintains metabolism. This hormone is thyroxine. Thyroxine production is controlled by thyroid stimulating hormone‚ which is released by the pituitary gland. TSH stimulates the thyroid gland to produce thyroxine. In this experiment‚ the effects of TSH and thyoxine on metabolic rate are investigated. Estrogen is a hormone produced by the ovaries that helps the uterus

To familiarize the student with histological identification of various endocrine glands Background The endocrine system consists of cells and tissues that secrete chemical messengers‚ called hormones‚ into the blood. The hormones are transported in the blood‚ via the circulatory system‚ to target cells. Once the hormone reaches the target cells and binds to a specific receptor

Luteinizing hormone is created by the pituitary gland and it is very important in the reproductive process as it allows ovulation to take place‚ alongside follicle stimulating hormones. The intermediate pineal is responsible for the production of melatonin which is considered to regulate the biological clock in humans‚ as it helps the brain to synchronise to daylight. The parathyroid gland is an extension of the thyroid gland‚ though this produced a separate hormone named parathormone.
