Objective:
Students will be able to compare and
contrast the nervous and endocrine
systems.

Objective:
Students will be able to distinguish
between steroid and nonsteroid hormones
and explain how each affects target cells.
Steroid
Form from Cholesterol
Examples: estrogen,
testosterone, aldosterone,
cortisol
Goes into nucleus and binds to DNA to
turn on genes.
Non-steroid
Form from other biomolecules:
primarily amino acids
Examples: amines
(norepinephrine, epinephrine),
peptides (antidiuretic hormone,
oxytocin), proteins (parathyroid
hormone, growth hormone)
Some form from glycoproteins--a
combination of protein and
carbohydrate
Examples: FSH, Luteinizing
hormone, thyroid-stimulating
hormone
Binds to membrane and triggers a
cascade in the cell.

Endocrine System and Nervous System
Similarities
• Both systems oversee cell-to-cell
communication using chemical signals
that bind to receptor molecules.
• Both regulate body processes to
maintain homeostasis.
• Both integrate other systems in
response to stimuli.

Objective:
Students will be able to discuss how
negative feedback mechanisms regulate
hormonal secretions.
Control of the Endocrine System
1. The hypothalamus and anterior pituitary
stimulate other endocrine glands
2. The nervous system stimulates a gland
directly
3. Changes in the internal environment
stimulate glands directly
All of the above involve negative feedback
mechanisms
see p. 295:
• Use fig. 11.17 to explain how blood
glucose concentration is maintained.
• Which of the 3 types of control are
involved?
