Chapter 19-1 Flashcards
Endocrine system + Hormones
Functions of Hormones (4)
- Regulate composition and volume of fluids
- Regulate metabolism and energy production
- Regulate rate and timing of growth & development
- Control physical and mental stress
Examples of endocrine system organs that are associated with each of the following
components of the body below:
The Brain (3)
- Pineal gland
- Hypothalamus
- Pituitary gland
Examples of endocrine system organs that are associated with each of the following
components of the body below:
The Neck (2)
- Thyroid
- Parathyroid gland
Examples of endocrine system organs that are associated with each of the following
components of the body below:
The Thoracic Cavity
Heart
Examples of endocrine system organs that are associated with each of the following
components of the body below:
The Abdominal Cavity
- Stomach
- Pancreas
- Small Intestine
Examples of endocrine system organs that are associated with each of the following
components of the body below:

Distinguish between the following aspects of hormone physiology:
a. Secretory cells
b. Target cells
a. Secretory cells— synthesis, stores and releases hormones
b. Target cells— contains receptors for specific hotmomones
Regarding hormone classification: Secretory cells, Target cells and examples of:
Autocrine Hormone
Secretary Cells: Autocrine (same)
Target Cells: Autocrine (same)
Examples: Interlueken-1
Regarding hormone classification: Secretory cells, Target cells and examples of:
Paracrine Hormones
Secretary Cells: Paracrine Cell
Target Cells: Paracrine receptor
Examples: Gastrin
Regarding hormone classification: Secretory cells, Target cells and examples of:
Endocrine Hormones
Secretary Cells: Into blood stream
Target Cells:
Examples: Insulin
Regarding water soluble and lipid soluble hormones: Benefits / Costs
Water-soluble Hormones
Benefits: Easily transported through bloodstream w/o the need of a transport protein
Costs: Cannot cross cell membrane of target cell must bind to receptor on cell surface membrane requiring energy
Location of Hormone receptor: Cell membrane surface
Regarding water soluble and lipid soluble hormones: Benefits / Costs
Lipid-soluble Hormones
Benefits: Can easily bind / diffuse across cell membrane of target cell. No energy needed.
Costs: Insoluble in blood plasma must be attached to transport protein that makes them soluble
Location: in blood
Explain the difference between the anterior and posterior pituitary gland, regarding the secretion and storage of hormones
Anterior: synthesizes, stores, releases hormones
Posterior: stores and releases hormones
Hormones released from the anterior pituitary gland, identify the target organ/tissue and( brief function):
Human Growth Hormone
Target: skeletal muscle, bone , cartilage
Function: promotion of cell growth
Hormones released from the anterior pituitary gland, identify the target organ/tissue and( brief function):
Prolactin
Target: Mammary gland
Function: milk production, development of mammary glands
