EXAM 2: Endocrine Overview 1 Flashcards
The endocrine system is made of:
Ductless glands that produce hormones
The endocrine system works in tandem with:
Nervous system
What do hormones act as?
Acts as a chemical agent transported by the bloodstream to target tissues, where it regulates/modifies activity of the target cell
How do endocrine responses compare to neural ones?
- slower to respond
- takes longer to act
The endocrine system works in tandem with the nervous system to regulate:
- metabolism
- internal environment
- BP
- stress response
- sexual reproduction
- Stimulation of sequential growth and development during childhood and adolescence
How does the endocrine system help control sexual reproduction?
- Differentiation of the reproductive system of developing fetus
- Coordination of both male and female reproductive systems
Overall, how does endocrine pathology develop?
As a result of dysfunction of different types of hormones
- releasing
- tropic (stimulating)
- effector hormones
OR
- defects in target tissue
Primary endocrine dysfunction
Dysfunction of the gland itself
Secondary endocrine dysfunction
- Caused by an external stimulus to the gland
- May be iatrogenic
Secondary endocrine dysfunction: iatrogenic
- surgical removal
- chemo
- etc
Endocrine dysfunction results in
Over- or underproduction of hormones
What are the glands of the endocrine system?
- hypothalamus
- pituitary
- thyroid
- parathyroid
- adrenals
- testes
- ovaries
- pancreas
- pineal
Parts of the adrenals
- cortex
- medulla
Parts of the pituitary
- anterior lobe
- posterior lobe
Pituitary aka
Hypophysis
