    HGH secretion in response to TRH was studied in patients with cerebrovascular disease in order to elucidate an influence of cerebrovascular lesions on the hypothalamus-anterior pituitary function. Blood specimens were obtained before and at the time of 10, 20, 30, 40, 60, 90 and 120 minutes after the intraveneous administration of 200 microgram of TRH in 17 patients with cerebral hemorrhage and in 8 patients with cerebral infarction. With regards to the natural fluctuations of serum HGH caused by cerebrovascular disease, the blood specimens were obrained at the time of 0, 30, 60, 90 and 120 minutes without the administration of TRH in 4 patients with cerebral hemorrhage and in 4 patients with cerebral infarction. Serum HGH was measured using the RIA method and the following results were obtained: 1) An increase in serum HGH was observed in 1 patient with cerebral hemorrhage out of 8 patients with cerebrovascular disease without TRH administration. 2) In 5 out of 17 patients with cerebral hemorrhage, an increase in serum HGH was observed following TRH administration. Three out of these 5 patients were included in the group of non-coma, and 4 out of the 5 patients were female. 3) In 2 out of 8 patients with cerebral infarction, an increase in serum HGH was observed following TRH administration.

    Regulation of Hormone Secretion01:19

    Regulation of Hormone Secretion

    Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.

    The Pituitary Gland01:17

    The Pituitary Gland

    The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.

    Hormones of the Pituitary Gland

    The small, pea-sized pituitary gland is located at the base of the brain. It is crucial in regulating various bodily functions, from growth to reproduction. The gland is divided into the anterior lobe and the posterior lobe. The secretory cell clusters in the pars distalis of the anterior pituitary lobe are controlled by hypothalamic regulators and synthesize six primary hormones.
    The most abundantly secreted hormone from the anterior lobe is the growth hormone, which controls overall growth by...
    Synthesis and Regulation of Thyroid Hormones01:20

    Synthesis and Regulation of Thyroid Hormones

    Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
    Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

    Functions of Thyroid Hormones

    The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
    TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

    Major Hormones and Their Functions

    Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
    Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.
