What is the function of the endocrine system? - CORRECT ANSWER- Control functions of
other systems in the body to maintain physiologic homeostasis
How is the endocrine system controlled? - CORRECT ANSWER- By nerve impulses,
neurotransmitters, and the hormones produced by itself
Describe the overall steps of endocrine communication - CORRECT ANSWER- 1. Starts
w/stimulation -- usually a change in internal/external environment
2. Endocrine cells produce hormones
3. The signal (hormone) travels through blood circulation
4. The hormone reaches a target cell w/receptors for the hormone
5. Ligand binds to receptor
6. Creates a signal transduction
7. Signal transduction leads to a physiologic response
What can endocrine cells be stimulated by? - CORRECT ANSWER- Homeostatic changes
in biomolecules and minerals in the plasma (Na, K, Ca, GLU, etc)
,By other hormones (example hypothalamic hormones and pituitary hormones
By nerve impulses and neurotransmitters
By immune responses ---pro/anti inflammatory cytokines
What are the 3 functional anatomical elements of the endocrine system? - CORRECT
ANSWER- Primary Endocrine Glands
Accessory Endocrinocytes all over the body systems
Hormones
What is the difference between Endocrine and Exocrine glands? - CORRECT ANSWER-
Endocrine --closed--release hormones into the bloodstream
Exocrine--open--release hormones directly onto body surfaces/cavities
What are the main endocrine glands?
What is a defining feature of all these glands? - CORRECT ANSWER- Hypothalamus
Pituitary Gland
,Pineal Gland
They are neuroendocrine glands --contain both endocrine and nervous tissues
What are the secondary endocrine glands? Why are they called secondary? -
CORRECT ANSWER- Thyroid
Parathyroid
Thymus
Adrenals
Pancreas
Ovaries
Testis
These glands are controlled by the main glands. They produce the terminal
hormones
, What is an example of a mixed gland? - CORRECT ANSWER- Pancreas
Has both exocrine and endocrine functions
Describe neuroendocrine cells - CORRECT ANSWER- Relay information between the
endocrine system and the nervous system
Receive Neuronal Input from the ANS and release hormones into blood
Major center of neuroendocrine integration is the hypothalamus and the pituitary
gland
Example is the neuroendocrine glands of the adrenal medulla
What are the three classes of hormones? - CORRECT ANSWER- Peptide/Protein
Hormones
Amine Hormones
Steroid Hormones
Describe the process of biosynthesis of peptide/protein hormones - CORRECT ANSWER-
A stimulus interacts with a hormonal gene
