|
The endocrine system consists of? |
A group of glands that produce regulatory chemicals called hormones. |
|
The endocrine system specialize |
in hormone secretion |
|
The nervous system is fast acting using |
Electrical signals |
|
The endocrine system is is slow or fast? |
Slow, and uses chemical messengers called hormones. |
|
Hormones |
Chemical messengers with regulatory effects on cells or organs. They are released into tissue fluids, not through ducts. The cells that make up these tissues have receptors on the membranes that they attach to |
|
Some hormones affect many tissues like |
Growth hormone Thyroid hormone Insulin |
|
Some affect a specific tissue |
(TSH) Thyroid-stimulating hormone (ACTH) Adrenocorticotropic hormone |
|
Hormone chemistry |
Amino acid compounds Proteins or related compounds All hormones except steroids Lipids-Steroids, Fatty acids, derived from the steroid cholesterol.... Produced in the adrenal cortex and sex glands... Prostaglandins are also lipids |
|
Negative feedback |
Endocrine gland over secretes hormone Tissue becomes too active Action negatively affects gland to decrease secretion |
|
Positive feedback |
Hormone response produces more hormone, needs a break- example child birth |
|
Rhythmic pattern |
pineal gland |
|
The pituitary gland is called the? |
Master gland and releases hormones that affect working of other endocrine glands. |
|
The pituitary gland is located where |
At the base of the brain, just below the hyopthalamus, to which it is attached via nerve fibers. It is the size of a pea It produces critical hormones, which are chemical substances that control various bodily functions. |
|
Pituitary structure Anterior lobe |
produces and release hormones |
|
Pituitary structure posterior lobe |
Anti diuretic hormone (ADH) and oxytocin stored here |
|
Pituitary structure |
infundibulum- the hollow stalk that connects the hypothalamus and the posterior pituitary gland |
