Endocrine

• Hormones secreted by the hypothalamus include oxytocin, antidiuretic hormone (ADH), growth-hormone releasing factor (GRF), corticotropin-releasing factor (CRF), thyrotropin-releasing hormone (TRH), dopamine, somatostatin, and melanocyte stimulating hormone (MSH).
• The adrenal glands produce hormones that help the body respond to stress and regulate blood pressure.
• Hormones secreted by the hypothalamus include oxytocin, antidiuretic hormone (ADH), growth-hormone releasing factor (GRF), corticotropin-releasing factor (CRF), thyrotropin-releasing hormone (TRH), dopamine, somatostatin, and melanocyte stimulating hormone (MSH).
• Posterior Pituitary Hormones: Oxytocin, Antidiuretic Hormone (ADH)
• Anterior Pituitary Hormones: Growth Hormone (GH), Prolactin (PRL), Adrenocorticotropic Hormone (ACTH), Thyroid Stimulating Hormone (TSH), Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH)
• The anterior pituitary gland is responsible for the secretion of growth hormone, thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, oxytocin, and melanocyte-stimulating hormone.
• Endocrine - a complex network of glands and organs
• Hormones - are chemical signals to control and coordinate body growth and development
• Glucagon - raises blood sugar levels
• Insulin - lowers blood sugar levels
• Hormone - chemical signals for body growth and development
• 2 types of glands: endocrine and exocrine
• endocrine - does not need a pathway; hormones are released into the bloodstream and travel to target organs
• exocrine - needs pathway for discharge (ex: semen to penis)
• Gonad - testis / ovary
• gametes - egg or sperm cells
• copulate -sexual intercourse
• inhibit - stop or slow down
• secrete - to produce or release
• stimulate - to instruct
• negative feedback - a system that responds to a change in the environment by returning the system to its original state
• positive feedback - a system that amplifies a change in a variable by returning it to the original value
• hypothalamus - HYPOGONADOX
• hypothalamus: gonadotropin releasing hormone (GnRH) - stimulate LH and FSH
• Luteneizing Hormone (LH) - helps regulate length and order of menstruation
• Follicle Stimulating Hormone - regualtes perbutal maturation
• hypothalamus: oxytocin - controls key aspects of reproductive system
• pituitary - master gland
• pituitary: growth releasing hormone (GHRH) - control growth and development of the body
• pituitary: prolactin - initiates milk production during pregnancy
• pituitary: melanocyte - stimulating hormone that increase melanin / pigment of skin
• pituitary: thyroid stimulating hormone - stimulate thyroid to produce thyoxin hormones
• pituitary: antidiuretic hormone (ADH) - stimulate kindey to absorb water
• pineal only produces: melatonin - regulate sleep cycle and body clock
• thyroid: wrapped around the trachea
• thyroid: thyroxine and triiodothyronine - regulates metabolism and mental health
• parathyroid: produces parathyroid hormones - regulates amount of calcium in blood levels
• high level of calcium: need calcitonin produced by: thyroid
• low level of calcium: need parathyroid hormones produced by: parathyroid
• thymus: mainly produces thymosin - immune system
