Endocrine Systematics
Barrett PetersBiomedical Research
Function and Format
Made up of all glands and hormones of the body
Stimulated by nervous system, chemical receptors, and other hormones.
Glands secrete hormones Regulates homeostasis
Organs/Peripherals
Adrenal gland Hypothalamus Pancreas Ovaries (f)/Testicles (m) Parathyroid gland Pineal gland Pituitary gland Thymus gland Thyroid gland
Adrenal Gland
Adrenal Cortex creates hormones to: -break down proteins-reduce inflammation-regulate mineral ions-regulate growth
Adrenal Medulla creates hormones to increase blood flow to brain and muscles during a “fight or flight” response
Hypothalamus
Part of the nervous system Specialized neurons influence hormone
production Controls other hormone producing
organs/glands by releasing stimulating hormones
Pancreas
Serves functions as endocrine organ and exocrine organ
Produces the hormone insulin to regulate blood sugar levels.
Ovaries/ Testicles
Ovaries create the female sex hormones
Estrogen develops female secondary sex characteristics and basic growth.
Progesterone maintains a suitable environment for an egg during ovulation.
Testicles produce male sex hormones. Testosterone induces growth and
development of male muscles, bones, and sex organs.
Parathyroid Gland
Located on the posterior side of the thyroid gland
Produces the hormone parathyroid hormone
Regulates calcium levels in blood, bones, and kidneys
Pineal Gland
Located near the thalamus in the brain. Produces melatonin to regulates
human circadian rhythm (sleep-wake cycle)
Triggered by photoreceptors to only produce Melatonin in low light conditions.
Pituitary Gland
Made up of 2 parts: -anterior -posterior Posterior section is part of Hypothalamus that regulates water levels in the body and aspects of pregnancy. Anterior region produces growth hormones and hormone stimulating hormones.
Thymus Gland
Prepares the body for growth during fetal development.
Helps defend the body from pathogens. Stops being active during puberty and
eventually gets replaced by adipose tissue.
Thyroid Gland
Located at base of neck around trachea. Produces three different hormones: Calcitonin,
T3, and T4 Regulates calcium levels if they get too high and
metabolic activities.
Relation to other systems
During a fight-or-flight response, blood flow from the cardiovascular system is increased to the muscular and nervous system.
Digestion and blood sugar levels are regulated by hormones produce by the endocrine system.
Calcium levels in bones and steady growth produced by the skeletal system are also regulated by hormone releasing gland.
Relation (cont.)
Reproductive organs and pregnancy are affected by glands in the endocrine system.
Aiding the immune and lymphatic systems that are fighting disease, the endocrine system reduces inflammation in parts of the body.
Diabetes
Diabetes is a disease related to the lack of production of insulin.
Without insulin, the body has no way to monitor and regulate blood sugar levels.
If not monitored, this disease could possibly be fatal by either having too high or too low blood sugar.
Fun Facts
The Hypothalamus is what makes you hungry and/or thirsty.
The endocrine system can directly affect human behavior.
There are a total of 30 different hormones in the human body.
GAMETIME!!!
Pick a partner One of you will be allowed to pick up
functions, the other will pick up organ names.
Coordinate with your partner to bring me the correct pairs first.
If you get one wrong you start all over.
