Endocrine system

The study of hormones

Affect many cells or tissues throughout the body (ex. HGH)

Affect only certain cells or tissues (ex. Adrenalin)

Glands that secrete substances anywhere else other than the blood stream (ex. Saliva)

Master gland because it exercises control over the other endocrine glands

Anterior- human growth hormone

Anterior- thyroid stimulating hormone

Anterior- adrenocorticotropic hormone ( adrenal)

Anterior- folical stimulating hormone, male- sperm production, female- egg maturing

Anterior- lutenizing hormone, male- testosterone, female- ovulation

Anterior- produce milk

Posterior- anti diuretic hormone, retain H2O

Posterior- releases milk, uterine contractions

• Natural (trampoline) • The drip • Gell on cervix • Break the water

Promotes the elongation of the skeleton

When too much HGH is released Acromegaly- bone plates do fuse Gigantism- bone plates don’t fuse

When too little HGH is released Dwarfism 1. Frolics- musproportioned 2. Primordial dwarfism

This hormone increases a persons metabolic rate ( rate they burn energy)

Calcium-in, helps regulate the amount of calcium in the blood. Let’s calcium into the cells, decreases blood calcium

Releases PTH, inhibits the release of calcitonin from the thyroid, increasing blood calcium

Exocrine and endocrine gland. Produces buffers in the digestive tract and regulates blood sugars

Produce hormones insulin and glucagon

In-cell-in, cause the muscles and liver to become more permeable to glucose, letting sugar into the cells, therefore reducing blood sugar levels

Glucose-be-gone, causes the liver to release glucose, therefore increasing blood sugar levels, necessary for needed energy in the cells
