Anterior pituitary

gland produces certain hormones such as adrenaline and the steroids aldosterone and cortisol. When cortisol concentrations in the blood are low the hypothalamus secretes corticotropin-releasing factor (CRF). CRF is released, stimulating the anterior pituitary to produce adrenocorticotropic hormone (ACTH) which, in turn, stimulates the adrenal cortex to release cortisol into circulation. When this happens, there is no homeostasis in the body, and sickness develops.…

Age of puberty attainment in beef cattle is an important aspect for producers. This is because age at puberty is a key factor for a heifer’s lifetime reproductive performance. Beef cattle management programs aim for heifers to conceive by two years of age, but this can be a challenge when producing Bos indicus cattle. Puberty attainment in Bos indicus cattle is considerably lengthier than Bos taurus cattle, with the age at first calving typically being 40 months or more (Nogueira, 2003).…

down to the spinal cord to the adrenal glands. This tells them to release the hormone called adrenaline. Once this adrenaline is released, it raises a person's blood pressure and increases your heart rate. The hypothalamus brings signals to the pituitary gland near the bottom of the brain. This tells the brain to release factors that have traveled through the bloodstream and stimulated the adrenal cortex to make a stress hormone called cortisol. Stress has many bad effects on the brain and its…

characteristics. Although the signs and symptoms of adolescents who have central precocious puberty develop not only due to an increase in androgens and estrogens, but also due to an increase in GnRH from the hypothalamus and LH and FSH from the anterior pituitary, and those who develop peripheral precocious puberty only reveal symptoms from an elevated secretion of androgens and estrogens, the physical clinical features are mostly identical. In females, common signs are early breast…

Thyroid Storm The hypothalamus, the anterior pituitary gland, and the thyroid gland all work together to regulate the thyroid hormones which in turn have a significant role in the regulation of the body’s metabolism and calcium balance (Pullen & Embrey, 2013, p. 14). When these components fail to maintain the appropriate balance of the thyroid hormones, the result can be either a hyperactive thyroid or a hypoactive thyroid. As a nurse, it is important to be able to identify patients who may be…

changes in behavior. There are a lot of cases of people who have become sociopathic because of pathological brain damage, for example a tumor. According to a report from 1992, a patient developed antisocial disorder after a surgery for removing a pituitary tumor. This harmed the orbitofrontal cortex (a component of the frontal lobe); however, neither neuropsychological nor personality tests showed particular mental default. Anna and Antonio Damasio, Portuguese neurologists, have announced in…

its release triggers the production of several other hormones that set ovulation in motion. Without this hormone, the ovulation process will not be triggered at all. GonaCon-B is a synthetic GnRH product that is too big to be diffused to the anterior pituitary, which is where the other hormones are triggered from, thus the product blocks ovulation. Having a single-dose vaccine that is effective over multiple years would reduce stress on the animals and cut down on the costs of multiple round-ups…

Compare and Contrast Diabetes There are many types of diabetes out there, we will specifically cover hypoglycemia, diabetic ketoacidosis, hyperglycemic, hyperosmolarity, and non-ketotic syndrome. First, let 's go over the endocrine system and why it is so important in controlling diabetes. The endocrine system helps your body maintain homeostasis, that is keeping your internal equilibrium at ease by adjusting continually to changing factors. Hormones helps regulate the internal environment by…

Section 1: Dr. E. Angela Murphy (Exercise, Nutrition and Immunity) Dr. Murphy’s current research focuses on 1) understanding how exercise stress affects immune functions and 2) understanding whether the use of proper nutrition can ameliorate the immune suppression caused by exercise stress. The overall goal of Dr. Murphy’s lecture was for students to gain an understanding of how exercise stress affects immune function, the mechanisms for these effects, and the benefits of proper nutrition on…
