Endocrine Glands & Hormones Flashcards
1
Q
Growth hormone (GH)
A
- Anterior pituitary
- Non-tropic
- Stimulates growth in long bones and skeletal muscles
2
Q
Prolactin (PRL)
A
- Anterior pituitary
- Non-tropic
- Stimulates milk production in breast tissue after childbirth
3
Q
Adrinocorticotropic Hormone (ACTH)
A
- Anterior pituitary
- Tropic
- Stimulates adrenal cortex to secrete glucocorticoids
4
Q
Thyroid-Stimulating Hormone (TSH)
A
- Anterior pituitary
- Tropic
- Stimulates the thyroid gland’s growth and activity
5
Q
Follicle-Stimulating Hormone (FSH)
A
- Anterior pituitary
- Tropic
- Stimulates production of ova and sperm in the ovaries and testes
6
Q
Luteinizing Hormone (LH)
A
- Anterior pituitary
- Tropic
- Triggers ovulation in females, stimulates testosterone production in males
7
Q
Oxytocin
A
- Posterior pituitary
- Causes contraction of uterus and milk ejection, breast “let-down” reflex
8
Q
Antidiuretic Hormone (ADH)
A
- Posterior pituitary
- promotes water reabsorption and retention by the kidneys
- inhibits urine production
9
Q
Calcitonin
A
- Thyroid
- Reduces blood calcium levels
10
Q
Thyroid Hormone (T3 and T4)
A
- Thyroid
- Stimulates metabolism
11
Q
Parathyroid Hormone (PTH)
A
- Parathyroid
- Raises blood calcium levels
12
Q
Epinephrine (adrenaline) & Norepinephrine (noradrenaline)
A
- Adrenal medulla
- Raises blood glucose levels, increases rate of metabolism, constricts some blood vessels
- Response to short-term stressors (fight or flight)
13
Q
Mineralocorticoids
A
- Adrenal cortex, zona glomerulosa (outer layer)
- E.g., Aldosterone
- Targets the kidneys to bring salt in (and therefore water)
14
Q
Glucocorticoids
A
- Adrenal cortex, zona fasiculata (middle layer)
- E.g., cortisol, cortisone
- Promotes normal cell metabolism, increase blood glucose levels
- Reduces long-term stressors
- Released in response to increased blood levels of ACTH
15
Q
Gonadocorticoids (sex hormones)
A
- Adrenal cortex, zona reticularis (inner layer)
- Mainly androgens produced but some estrogens too
- Small amounts made throughout life
