Question

Ребят помогите пожалуйста... гипофиз и его влияние ​

Answer 1

Ответ:

Гипофиз.

Функции гипофиза:

-управление деятельностью эндокринной системы;

-контроль роста тела: вырабатывает гормон соматропин(гормон роста).

При избытке соматропина развиваются болезни акромегалия, гигантизм.

При недостатке соматропина развивается карликовость.

Объяснение:

Answer 2

Ответ:

Больше всего важных для здоровья гормонов вырабатывается в передней доле гипофиза. Гормоны аденогипофиза контролируют рост, деятельность щитовидной железы, надпочечников, половых желез. В промежуточной доле секретируется гормон, стимулирующий активность клеток, вырабатывающих меланин и отвечающих за пигментацию кожи.

Answer 3

The Hypothalamus and Its Influence

The hypothalamus is a small but crucial part of the brain that plays a significant role in regulating various bodily functions and maintaining homeostasis. It is located at the base of the brain, just above the pituitary gland. The hypothalamus acts as a link between the nervous system and the endocrine system, which is responsible for producing and releasing hormones into the bloodstream.

Functions of the Hypothalamus: 1. Regulation of Body Temperature: The hypothalamus helps regulate body temperature by monitoring the temperature of the blood and initiating appropriate responses to maintain a stable internal temperature. 2. Control of Hunger and Thirst: The hypothalamus plays a role in regulating appetite and thirst. It receives signals from the body indicating hunger or thirst and initiates appropriate responses to satisfy these needs. 3. Sleep-Wake Cycle: The hypothalamus helps regulate the sleep-wake cycle by influencing the production of melatonin, a hormone that promotes sleepiness. 4. Emotional Responses: The hypothalamus is involved in the regulation of emotions and emotional responses. It receives input from various parts of the brain and helps coordinate emotional and behavioral responses. 5. Control of the Autonomic Nervous System: The hypothalamus helps regulate the autonomic nervous system, which controls involuntary bodily functions such as heart rate, blood pressure, and digestion. 6. Hormone Regulation: The hypothalamus produces and releases various hormones that control the function of the pituitary gland, which is often referred to as the "master gland" because it regulates the activity of other endocrine glands in the body.

Influence of the Hypothalamus on the Pituitary Gland: The hypothalamus and the pituitary gland work together to regulate many bodily functions. The hypothalamus produces hormones that control the release of hormones from the pituitary gland. These hormones are known as releasing hormones or inhibiting hormones, depending on whether they stimulate or inhibit the release of specific pituitary hormones.

The hypothalamus produces several releasing hormones, including: - Gonadotropin-releasing hormone (GnRH): Stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland, which are involved in the regulation of reproductive functions. - Thyrotropin-releasing hormone (TRH): Stimulates the release of thyroid-stimulating hormone (TSH) from the pituitary gland, which regulates the function of the thyroid gland. - Corticotropin-releasing hormone (CRH): Stimulates the release of adrenocorticotropic hormone (ACTH) from the pituitary gland, which regulates the production of cortisol by the adrenal glands. - Prolactin-inhibiting hormone (PIH): Inhibits the release of prolactin from the pituitary gland, which is involved in milk production and breastfeeding.

In summary, the hypothalamus plays a crucial role in regulating various bodily functions and maintaining homeostasis. It influences the pituitary gland by producing hormones that control the release of other hormones throughout the body. This intricate relationship between the hypothalamus and the pituitary gland is essential for the proper functioning of the endocrine system.
