| Cushing's syndrome | a long-term excess of glucocorticiods, many symptoms: depression, fatigue, hirsutism, various autonomic symptoms, and psychosis
🗑
|
||||
| Islets of Langerhans | are clusters of cells through out the pancreas that secrete hormones directly into the bloodstream- hormones secreted include insulin and glucagon
🗑
|
||||
| Melatonin | is an amine hormone released by the pineal, plays a role in biological rythms, especially the timing of sleep onset
🗑
|
||||
| Pineal gland | sits atop the brainstem and in mammals is overlaid by the cerebral hemispheres. It is a signal structure
🗑
|
||||
| Gonadotopin-inhibiting hormone | hypothalamic peptide that inhibits gonadotropins
🗑
|
||||
| Ovaries | paired female gonads
🗑
|
||||
| Estrogen and Progestin | two major classes of steroid hormones that the ovary produce
🗑
|
||||
| Testes | are sperm producing sertoli cells and leydig cells, which produce and secrete the sex steroid testosterone and androgens
🗑
|
||||
| Gonads | consis of two different subcompartments-one to produce hormones and another to produce gametes
🗑
|
||||
| cretinism-congenital hypothyroidism | thyroid deficiency early in life can cause marded reduction in brain size and branching of axons and dentrites
🗑
|
||||
| goiter | thyroid hormones are dependent on the supply of iodine-hyperthyroidism-driven by higher and higher TSH levels. the thyroid gland swells in its attempt to produce more thyroid hormones
🗑
|
||||
| Thyrotropin-releasing hormone TRH | stimilates the release of TSH form the pituitary
🗑
|
||||
| thyroid gland | gland that produces and secretes several hormones, two are, thyroxine and triiodothyronine
🗑
|
||||
| Androstenedione | contributes to the adultpattern of body hair in men and women
🗑
|
||||
| Mineralocorticoids | have effects on minerals such as sodium and potassium.
🗑
|
||||
| Aldosterone | the primary mineralocorticiod, acts on the kidneys to retain sodium and thus reduces and amount of urine produced, conserving water.
🗑
|
||||
| Cortisol | increases the level of blood glucose and accelerate the breakdown of carbohydrates, including glucose.
🗑
|
||||
| Adrenocorticoids | a variety of steroid hormones that are produced and secreted from the adrenal cortex
🗑
|
||||
| Glucocorticoids | hormones that have effects on the metabolism of carbohydrates, including glucose
🗑
|
||||
| Epinephrine & Norephinephrine | released by the adrenal medulla, amine hormones that are under the control of the sympathetic nervous system
🗑
|
||||
| Adrenal Medulla | 20% of the adrenal gland, really a protion of the sympathetic nervous system because it is richly supplied with autononmic nerves
🗑
|
||||
| Adrenal Cortex | 80% of the adrenal gland, is composed of distinct layers of cells, each producing different steroid hormones
🗑
|
||||
| Adrenal Gland | rests on top of each kidney, it secretes a large variety of hormones in mammals, it is divided into two major portions
🗑
|
||||
| Prolactin | it stimulates lactation in female mammals. has a number of roles in addition to its actions on breast tissue. it is closely involved in teh parental behavior of a wide variety of vertebrate species
🗑
|
||||
| Milk letdown reflex | triggered by oxytocin, the contraction of mammary gland cells that ejects mild into the breast ducts-exemplifies the relationship between behavioral and hormone release
🗑
|
||||
| Posterior pituitary gland | secretes two principal hormones, oxytocin and arginine vasopressin
🗑
