Endocrine System Flashcards
Responsible for the secretion of hormones in the development of organisms
Endocrine System
______(Duct gland)
Secretion______
Method of Transport_____
Target_______
Exocrine(Duct gland)
Secretion : Enzymes
Method of Transport : Duct
Target : Organ near gland
______(Ductless gland)
Secretion______
Method of Transport_____
Target_______
Endocrine (Ductless gland)
Secretion : Hormones
Method of Transport : Bloodstream
Target : Organ distant from gland
Stimulates development of male sex organs and secondary sex characteristics
Testosterone
Stimulates development of female sex organs and secondary sex characteristics, maturation follicles, formation and maintenance of bone tissue and contraction of uterine muscles
Estrogens
- Estradiol
- Estrone
- Estriol
Stimulates secretion of substance from the lining of the uterus (endometrium) in preparation for egg implantation in the uterine wall
Progesterone
Stimulate cellular metabolism, lipid production, carbohydrate utilization, and CNS and ANS activation
Thyroxine (T4)
Triiodothyronine (T3)
C- Cells of thyroid gland which decrease calcium levels in the blood
Calcitonin
Secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and then onto a bodily surface or into the lumen.
-No part of the cell is lost (Only Secretes enzymes)
Merocrine
Ex. Salivary Glands
Bud their secretions off through the plasma membrane producing extracellular membrane-bound vesicles.
-Some parts of the cells are long along with secretions
Apocrine
Ex. Mammary Glands
Secretions are produced in the cytoplasm of the cell and released by the rupture of the plasma membrane, which destroys the cell and results in the secretion of the product into the lumen.
-The whole cell detaches with secretion
Halocrine
Ex. Sweat Glands/Sebaceous Glands
- Long Distance chemical signals
- Travel via blood and lymph
Hormones
Process of maintaining physiological balance
Homeostasis
Stimulates “fight of flight” response, increases heart rate, dilates blood vessels, increase blood glucose
Epinephrine (Adrenaline)
Stimulates “fight of flight” response, increases heart rate, dilates blood vessels, increase blood glucose
Norepinephrine (noradrenaline)
