Ricky Garcia P.7 Endocrine system
Compare and Contrast Steroid and Non-Steroid Hormone's
Steroid hormones: Lipid Soluble, Have the Ability to move through cell membranes
Non-Steroid Hormones: Combine with receptors In the targeted cell membrane instead of passing through them.
Negative and Positive Feedback.
Positive Feedback: positive feedback is used when level's in the body become abnormal and is used as a Re-stabilization Method.
Negative feedback: Negative feedback is necessary when hormone production needs to be decreased or stopped. When a hormone level drops below its needed amount, the negative feedback lock is broken therefore resuming hormone production.
Hormone's and the Target Cells.
Pituitary Gland
Growth Hormone: Increases Body size
prolactin: Sustains milk production for Babies after birth.
Thyroid Stimulating Hormone: Controls secretion of Hormone's from Thyroid Gland.
Adrenocorticotropic
hormone: controls secretions from Adrenal cortex.
Follicle Stimulating Hormone: In females- responsible for development of Egg's
Male- Development of Sperm cells.
Oxytocin: contracts smooth muscle in the Uterine walls
Thyroid Gland
Thyroxin: Increases rate of energy release from carbohydrates
Necessary for Normal Nervous system Maturation
Calcitonin: Lowers blood calcium and phosphate Ion concentrations.
Triiodothyronine: Does the Same as Thyroxin but 5 times more potent
Pancreatic
Glucagon: Increases Blood Glucose levels by stimulating breakdown of glycogen. Low Blood glucose levels stimulate the secretion of of glucagon.
Insulin: Decreases blood glucose level by stimulating the liver.
High blood glucose stimulates the release of insulin.
Diseases associated with Endocrine system
Section 1
Thyroidism
Hyperthyroidism: When the thyroid is overworked and has difficulties producing hormone's In the correct quantity. This leads to overproduction of thyroid hormones.
Hypothyroidism: When the Thyroid is underworked meaning it does not produce the required amount of hormone's needed leading to difficulties in some bodily functions.
Diabetes
Type 1: An autoimmune disorder when beta cells are destroyed and insulin production is stopped
Type 2: When insulin is produced but the body can't recognize it. Also known as the body being (Non Insulin dependent)
Major Endocrine Glands/organs and their Function
Pituitary Gland: Secrets Growth Hormones,Prolactin, and thyroid stimulating hormones, ACTH,FSH,LH,and Oxytocin.
pineal Gland: Secretes melatonin which helps the body sleep. Is released at night and surpassed during the day.
Thyroid Gland: contains 2 hormones that help calorie intake and the regulation of blood calcium levels and bone growth.
Reproductive glands: Responsible for the production of Estrogen and progesterone as well as estrogen.
Parathyroid Gland: Secrets a hormone (PTH) increases blood calcium ion concentration,stimulates bone resorption by osteoclasts, stimulates kidneys, causes activation of Vitamin D
Kidneys: Secrete erythropoietin for blood cell production.
Adrenal Glands: Releases Epinephrine and norepinephrine which are triggered during fight or flight responses.
Thymus Gland: Secretes thymosins which affects the T lymphocytes (White blood cells). These are important to Immunity
Pancreas: Secretes hormones as an endocrine gland and digestive juice into the stomach as an exocrine gland. Pancreatic hormones are released to control the level's of blood glucose.
The pancreas also releases Glucagon and Insulin.
Heart: Secretes atrial natriuretic peptide which affects sodium and water excretion in Kidneys.
Major Functions of the Endocrine system
The Endocrine system is a structure in the Body that is made up of Tissue, Organs, and Glands.
The Endocrine system works with the Nervous system to maintain Homeostasis in the body through the use of the Glands by secreting hormone's needed for our everyday life.
