Chapter16-Endocrine Flashcards
Which 2 hormones are found in the posterior pituitary (Neurohypophysis) ?
- oxytocin
- antidouretic hormone (ADH)/(Vasopressin)
Which 6 hormones are found in the anterior pituitary?
- Growth hormone (GH)
- Thyroid stimulating hormone (TSH)
- Adrenocorticotropic hormone(ACTH)
- Prolactin (PRL)
- -Gonadotropins (FSH/LH):
- Follicle stimulating hormone
- Luteinizing hormone
Growth hormone?
GH
- generalized
- metabolizes fat to use for energy
- stimulates liver to release glucose
Thyroid Stimulating Hormone (TSH) ?
- Targets Thyroid gland
- release of thyroid hormone
Adrenocorticotropic Hormone (ACTH) ?
- targets adrenal cortex
- release of cortisol -glucocorticoid
- growth and development of adrenal cortex
Prolactin (PRL) ?
- targets breasts
- lactation (milk production )
What are the two Gonadotropins ?
Follicle stimulating hormone (FSH)
And
Luteinizing Hormone (LH)
Follicle Stimulating Hormone (FSH) ?
- targets ovaries and testes
- follicle maturation and egg production
- sperm production
Luteinizing Hormone (LH) ?
- targets ovaries and testes
- ovulation: release of an egg
- progesterone production
Oxytocin ?
- targets uterus and breasts
- uterine contraction
- milk ejection
Antidouretic Hormone (ADH) ?
-targets kidneys
- water reabsorption
- elevates blood pressure
What 3 hormones are found in thyroid gland?
- Thyroxine (t4)
- Triiodothyronine (T3)
- Calcitonin
Thyroxine (T4) ?
- target generalized
- increases metabolic rate
- enhances protein synthesis
Triiodothyronine (T3) ?
- targets generalized
- increases metabolic rate
- enhances protein synthesis
Calcitonin is produced by what cells?
Parafollicular cells
Calcitonin?
-targets osseous tissue
- inhibits osteoclasts activity
- stimulates osteoblasts: lowers blood Ca
What hormones are in the parathyroid glands?
-parathyroid hormone (PTH)
Parathormone
-parathyroid hormone (PTH)?
- targets kidneys
- activation of vitamin D
What 3 hormones are in the adrenal cortex?
- aldosterone (zona glomerulosa)
- cortisol (zona fasciculata)
- androgens (zona reticularis)
Aldosterone ?
- targets kidneys
- increases sodium levels in blood
Cortisol?
- targets generalized
- depresses inflammatory and immune response
Androgens ?
- target males and females
- increases sexual drive
What two hormones are found in the adrenal medulla?
- epinephrine
- norepinephrine
Epinephrine ?
- targets cardiovascular system
- increased heart rate
Norepinephrine ?
- targets cardiovascular system
- vasoconstriction increases blood pressure
What 2 hormones are found in the pancreas ?
- glucagon
- insulin
Glucagon?
- targets liver
- breakdown of glycogen
Insulin?
- targets liver
- inhibits glycogen breakdown
What 2 hormones are found in the ovaries?
- estrogen
- progesterone
Estrogen?
Maturation of reproductive system
Progesterone?
Stimulates increase in thickness of uterine lining
What hormone is found in the testes?
Testosterone
What does testosterone do?
Maturation of reproductive system
What hormone is found in the pineal gland?
Melatonin
What is melatonin?
Hormone that
- targets brain
- stimulates sleep at night
Which hormones are found in the thymus?
Thymopoitins, Thymosins
Thymopoitins, Thymosins?
Development of T cells
What hormone is found in the placenta?
- human chorionic gonadotropin
Human chorionic gonadotropin?
-maintains the corpus luteum during pregnancy
What hormone is found in the heart?
Atrial Natriuretic Hormone
Atrial Natriuretic Hormone (ANH or ANP)?
- targets kidneys
- lowers blood pressure
