Endocrine System Flashcards
Organs and tissues and the hormones they produce
What is the second major control system of the body
Endocrine system
What is the difference between the endocrine system and nervous system?
Endocrine system uses chemical impulses, hormones
arouses the body tissue and cells by stimulating changes in their metabolic activity. This includes growth, development, and physiological homeostasis
Hormones
can be steriods or amino acid based molecules
hormones
How does a hormone travel?
Through the blood
Cells within an organ that respond to a certain hormone
Target cells
Two functional lobes of the pituitary
adenohypophysis and neurohypophysis
anterior pituitary
adenohypophysis
stalk attaching the pituitary to the hypothalamus
neurohypophhysis
Which part of the pituitary secretes the 4 tropic hormones?
Anterior pituitary
Hormones that have other endocrine glands as their target
Tropic hormones
Is the posterior pituitary an endocrine gland?
No
Why is the posterior pituitary not considered an endocrine gland?
- It does not synthesize the hormones it releases. 2. it acts as a storage area for two neurohormones transpported to it
What are the tropic hormones of the pituitary gland?
- Thyroid stimulating hormone (tsh). 2. follicle stimulating hormone ( FSH). 3. Luetenizing hormone (LH) 4. Adrenocorticotropic hormone (ACTH)
TSH target gland
Thyroid gland
TSH effects
Stimulation of thyroid hormones
Target of follicle stimulating hormone
Ovaries and testes
Effects of FSH
Ovaries- stimulates ovarian follicle maturation and estrogen production. Testes- Stimulates sperm production
Target cell of LH
Ovaries and testes
Effects of LH
Stimulates ovulation and triggers ovarian production of estrogen and progesterone. Males- Stimulates testosterone production
