Concepts of Biology 2013-04-25T00:00:00Z The peptide hormones include molecules that are short polypeptide chains, such as antidiuretic hormone and oxytocin produced in the brain and released into the blood in the posterior pituitary gland. Biology for AP Courses 2022-06-09T00:00:00Z When blood volume drops 5–10 percent, causing a decrease in blood pressure, there is a rapid and significant increase in ADH release from the posterior pituitary. Anatomy and Physiology 2013-06-19T00:00:00Z As this rise of blood pressure is probably controlled by the posterior pituitary, we have a clue to the reason for the rhythmic variations in the rate of production of its secretion by the ovary. The Glands Regulating Personality A positive feedback relay occurs between the uterus, hypothalamus, and the posterior pituitary to assure an adequate supply of oxytocin. Biology for AP Courses 2022-06-09T00:00:00Z This causes the cervix to stretch and nerve impulses are sent to the hypothalamus, which signals the release of oxytocin from the posterior pituitary. Concepts of Biology 2013-04-25T00:00:00Z Oxytocin release is stimulated by the suckling of an infant, which triggers the synthesis of oxytocin in the hypothalamus and its release into circulation at the posterior pituitary. Biology for AP Courses 2022-06-09T00:00:00Z The posterior pituitary gland does not produce hormones, but rather stores and secretes hormones produced by the hypothalamus. Anatomy and Physiology 2013-06-19T00:00:00Z While the ovary, stimulated by the thyroid and the adrenal medulla, is the chief determinant of the sex instinct, to the posterior pituitary must be credited the chief hormone of the maternal instinct. The Glands Regulating Personality A feedback relay occurs between the uterus, hypothalamus, and posterior pituitary to assure an adequate supply of oxytocin, which causes the contraction of smooth muscles of the uterus, leading to the birth of the baby. Biology for AP Courses 2022-06-09T00:00:00Z The posterior pituitary continuously produces oxytocin, which is sufficient for muscular contraction in the uterus, thereby causing the birth of the baby. Biology for AP Courses 2022-06-09T00:00:00Z It is a part of the brain, extending down from the hypothalamus, and contains mostly nerve fibers and neuroglial cells, which support axons that extend from the hypothalamus to the posterior pituitary. Biology for AP Courses 2022-06-09T00:00:00Z Recall that the posterior pituitary does not synthesize hormones, but merely stores them. Anatomy and Physiology 2013-06-19T00:00:00Z For normally, with feminine puberty, there is an increased activity of the thyroid, the posterior pituitary and the adrenal medulla. The Glands Regulating Personality The posterior pituitary is an extension of the hypothalamus. Biology for AP Courses 2022-06-09T00:00:00Z If the posterior pituitary does not release enough ADH, water cannot be retained by the kidneys and is lost as urine. Biology for AP Courses 2022-06-09T00:00:00Z The posterior pituitary and the infundibulum together are referred to as the neurohypophysis. Biology for AP Courses 2022-06-09T00:00:00Z These hormones travel along the axons into storage sites in the axon terminals of the posterior pituitary. Anatomy and Physiology 2013-06-19T00:00:00Z Ovary and adrenal medulla and posterior pituitary and thyroid predominance constitute the feminine formula. The Glands Regulating Personality The hypothalamus acts as an endocrine organ, synthesizing hormones and transporting them along axons to the posterior pituitary gland. Biology for AP Courses 2022-06-09T00:00:00Z The anterior portion of the pituitary gland is regulated by releasing or release-inhibiting hormones produced by the hypothalamus, and the posterior pituitary receives signals via neurosecretory cells to release hormones produced by the hypothalamus. Biology for AP Courses 2022-06-09T00:00:00Z The posterior pituitary itself does not produce hormones, but instead stores hormones produced by the hypothalamus and releases them into the blood stream. Biology for AP Courses 2022-06-09T00:00:00Z There are three regions: the pars distalis is the most anterior, the pars intermedia is adjacent to the posterior pituitary, and the pars tuberalis is a slender “tube” that wraps the infundibulum. Anatomy and Physiology 2013-06-19T00:00:00Z When the posterior pituitary begins to secrete more in her its stimulation of the thyroid is enough to tip it over the normal line. The Glands Regulating Personality The pituitary has two distinct regions—the anterior pituitary and the posterior pituitary—which between them secrete nine different peptide or protein hormones. Biology for AP Courses 2022-06-09T00:00:00Z Alcohol increases GFR by inhibiting ADH release from the posterior pituitary, resulting in less water recovery by the collecting duct. Anatomy and Physiology 2013-06-19T00:00:00Z It is formed by the hypothalamus and is stored and released from the posterior pituitary. Biology for AP Courses 2022-06-09T00:00:00Z Each collecting duct collects forming urine from several nephrons and responds to the posterior pituitary hormone ADH by inserting aquaporin water channels into the cell membrane to fine tune water recovery. Anatomy and Physiology 2013-06-19T00:00:00Z The interactions of the two glands, the ovary and the posterior pituitary, modified by accessory influences, determine the relative intensity of the two instincts. The Glands Regulating Personality ADH, a 9-amino acid peptide released by the posterior pituitary, works to do the exact opposite. Anatomy and Physiology 2013-06-19T00:00:00Z Or the uterus may not have received enough posterior pituitary or thyroid to make it fit soil for the ovum to plant itself in. The Glands Regulating Personality This causes the cervix to stretch and nerve impulses are sent to the hypothalamus, which signals for the release of oxytocin from the posterior pituitary. Biology for AP Courses 2022-06-09T00:00:00Z When the osmoreceptors in the hypothalamus detect an increase in the concentration of blood plasma, the hypothalamus signals the release of ADH from the posterior pituitary into the blood. Anatomy and Physiology 2013-06-19T00:00:00Z The female's various emulsions of coyness and display are motivated by posterior pituitary and gonad hormones in alliance.
