A&P BIOD Module 6: Problem Set
1. Does the nervous system or the endocrine system react faster to external/
internal stimuli?
1. The nervous system
2. What are the two major groups of hormones and what are their derivatives?
2. 1- Peptide (derived from proteins and catecholamines)
2- Steroids (derived from cholesterol)
5. True or false: Endocrine glands contain ducts and secrete their contents directly
into an epithelial lining.
False
primary endocrine organs
Primary Endocrine Organs thru the body
Posterior view of the thyroid gland
, Secondary endocrine organs
9. Name three secondary endocrine organs.
heart, thymus, kidney, gonads
10. Describe homeostasis in the body.
10. (set-point) is a range in which the body acts to maintain all its levels for
function.
11. During negative feedback a hormone level is high. What happens to hormone
production?
11. The brain detects the hormone level is too high and hormone production is
shut off.
12. The action of oxytocin works through positive or negative feedback?
12. Positive feedback.
19. Fill in the chart, below with the purpose and target of each of the anterior
pituitary hormones:
Hormone Target Action GH All body cells Growth of body (height)
Promotion of cell division
Protein synthesis
Bone growth- stimulation of osteoblasts TSH Thyroid gland Thyroid gland (to
produce T3, T4) Gonadotropic hormones (FSH, LH) Gonads(Testes, ovaries)
