9.3 Kahoot - exam Flashcards
What is the major endocrine gland invoved in stress?
Adrenal Gland
The two layers of the adrenal glands are the:
medulla and cortex
Which is the INNER portion of the adrenal gland ?
Medulla
What hormones are secreted by the adrenal medulla?
norepinephrine and epinephrine
How is the adrenal medulla stimulated to release hormones?
Sympathetic nerves
responses by the body to the release of epinephrine?
- decreased digestive activity
- faster heart rate
- incerased blood glucose
What type of stress does the adrenal medulla respond to?
short term
What is anaphylaxis?
severe, immediate allergic reaction
How do EpiPens help treat anaphylaxis?
they dialate the bronchioles
Which is the OUTER portion of the adrenal gland ?
cortex
What stimulates the release of hormones from the adrenal cortex?
Adrenocorticotropic hormone (ACTH)
What hormones are secreted by the Adrenal Cortex?
- androgens
- glucocorticoids
- mineralocorticoids
the adrenal cortex responds to what type of stress?
long term
What gland releases adrenocorticotropic hormone (ACTH)?
Anterior pituitary gland
The release of adrenocorticotropic hormone (ACTH) from the pituitary is stimulated by:
Corticotropin releasing hormone from the hypothalamus
Negative feedback controlling cortisol levels occurs where?
Hypothalamus and Anterior Pituitary
People with chronic stress have high levels of cortisol
True
What effect can high levels of cortisol have on the body?
decreased immune function
Aldosterone mainly effects the cells of what organ?
kidney
What physiological change occurs when aldosterone is released?
Higher blood pressure
Addison’s Disease is caused by decreased hormone levels by what gland?
adrenal cortex
Where is the pancreas found?
By the stomach
What 2 pancreatic hormones are involved in blood sugar homeostasis?
insulin and glucagon
