Overview

The endocrine system is a radio. It is slower,
but it gets out to more people. The chemical
messages get to more cells.

Endocrine- secretes hormones in to blood
stream and extracellular fluid

Exocrine-secretes substance directly at the
target (Not important yet)
Endocrine Glands








Pineal Gland
Hypothalamus
Pituitary
Thyroid/Parathyroid
Thymus
Adrenal Glands
Pancreas
Gonads (Ovaries and Testes)
pineal and hypothalamus


Pineal- releases melatonin which
helps to regulate the biological
clock
Hypothalamus- regulates
pituitary gland. It makes the
hormones that are stored in the
pituitary gland
pituitary and thyroid/parathyroid


Pituitary- Produces hormones
that regulate many other
endocrine glands.
Thyroid/Parathyroid- The thyroid
regulates metabolism. The
parathyroid regulates the amount
of sodium in the blood.
thymus and adrenal


Thymus- During childhood, the
thymus stimulates T-cell
development
Adrenal- stimulates the
production of epinephrine and
norepinephrine to aid the body in
fight, flight, or, fright situations.
Pancreas

Pancreas- it produces insulin and
glucagon.
Gonads (and strife)
Ovaries- produce estrogen and
progesterone (in females).
Responsible for secondary sexual
development.
Testes- produce testosterone (in
males). Responsible for sperm
production and secondary sexual
development.
How the Hormones Work




Most hormones work by binding to
receptors on the target cells.
Steroid hormones can enter a cell and alter
DNA sequences.
Non-Steroid hormones CAN’T enter a cell,
so they have to bind to receptors and use a
secondary messenger.
Hormones are secreted into extracellular
fluid, or directly into the blood stream.
