Endocrine and Respiratory Flashcards
Hypophysis or master gland
Pituitary gland
Two parts of the pituitary gland
Adenohypophysis
Neurohypophysis
The pituitary gland is connected to the hypothalamus by the..
Infundibular stalk
Secretion of the adenohypophysis
GPA: B FLAT Acidophiles: Growth hormone Prolactin Basophiles: Follicle Stimulating Hormone Luteinizing Hormone Adrenocorticotropic Hormone Thyroid-Stimulating Hormone
Chondrogenesis and protein anabolism
Growth Hormone/Somatotropin
Glycogenolysis and lipolysis
Growth Hormone/Somatotropin
Stimulates milk production in mammary gland
Prolactin
Srimulates Gametogenesis
Follicle Stimulating Hormone
Stimulates estrogen production
Follicle stimulating Hormone
Stimulates androgen-binding protein production in males
Follicle stimulating hormone
Stimulates Ovulation and formation of corpus luteum in females
Luteinizing hormone
Stimulates testosterone production in males
Luteinizing hormone
Stimulates zona fasciculata to produce cortisol
Adrenocorticotropic hormone/corticotropin
Stimulates thyroid to produce t3 and t4
Thyroid stimulating hormone
Hypothalamic hormone ehich inhibits release of growth hormone
Somatostatin
Hypothalamic hormone which inhibits prolactin release
Dopamine/prolactin-inhibiting hormone
Excessive cortisol will tesult to..
Cushings disease
Deficient cortisol will result to..
Addisons disease
Excessive thyroid hormone will result to..
Hyperthyroidism
Deficient thyroid hormones will tesult to..
Hypothyroidism
This is secreted by the hypothalamus neurosecretory fells during puberty..
Gonadotropin releasing hormone
Targets sertoli cells to produce androgen binding protein
Follicle stimulating hormone
Targets leydig cells to produce testosterone
Luteinizing hormone
Testosterone binds to Androgen binding protein
Spermatogenesis
Sertoli cells produce ___ when stimulated by follice stimulating hormone
Androgen binding protein
Leydig cells produce ___ when stimulated by luteinizing hormones
Testosterone (androgen)
Is responsible for the secondary male characteristics
Testosterone
Will increase the production of estrogen
Granulosa cells binds to follicle stimulating hormone
Responsibke for primordial follicle development, secondary female characteristics, slight thickening of the endometrial lining
Estrogen
Allows development of graafian follicles to corpus luteum
Ovulation
Corpus luteum produces
Prolactin
Inhibin
Estrogen
Main hormone for inhibiting follicle stimulating hormone
Inhibin
Inhibits folkicle stimulating hormone; thickens endometrial lining and stimulates Prolactin releasing hormone
Progesterone and Estrogen
Main hormone for pregnancy and menstruation
Progesterone
Hormonal pills are usullay taken for how many days?
21/28
Doesn’t secrete hormones but serve as storage for hornones secrered by the hypothalamus
Posterior Pituitary gland or Neurohypophysis
What are the two hypothalamic nuclei secretory cells
Paraventricular nuclei
Supraoptic Nuclei
Hormone secreted by the paraventricular nuclei
Oxytocin
Hormone released by the Supraoptic Nuclei
Antidiuretic hormone or vasopressin
Hormonefor uterine contractions
Oxytocin
Hormone for milk secretion
Oxytocin
Increases reabsorption of water in distal convoluted tubules and collecting ducts, constrics arterioles increasing blood pressure
Antidiuretic hormone or Vasopressin
Deficiency of anti diuretic hornone or vasopressi
Diabetes insipidus
Largest endocrine gland
Thyroid gland
Butterfly shape of H shape gland
Thyroid gland
Connects the right and left thyroid gland
Isthmus
Located below the thyroid cartilage just level of cricoid cartilage
Thyroid gland
Cells of the thyroid gland
Follicular cells
Parafollicular cells
Secretions of the follicular cells
Triiodothyronine
Thyroxine
Secretion of the parafollicular cells
Calcitonin
Increase metabolic functions of the body
T3 and T4
Decrease blood calcium
Calcitonin
Excessive metabolic function
Hyperthyroidism
Most common cause of hyperthyroidism is
Graves disease
Plumbers disease
Drugs contraindicated for hyperthyroidism
Epinephrine
Most common cause of hypothyroidism is
Hashimoto’s thyroiditis
Iodine deficiency
Hypothyroidism in children
Cretinism
Severe type of hypothyroidism
Myxedema
Drugs for Hypothyroidism
Synfhetic thyroxine
Found posterior to the thyroid gland; secretes parathyroid hormone
Parathyroid gland
Parathyroid hormones are produced by..
Chief cells of the Parathyroid gland
Increase blood calcium levels by bone resorption and increase reabsorption in DCT; increase calcitriol formation
Parathyroid hormone
Severe form of Hyperparathyroidism
Von-recklinghausens Disease
Features osteoporotic bone, absence of lamina dura and hypercalcemia
Hyperparathyroidism
Common features of hypoparathyroidism
Hypocalcemia
Tetany
Chvostek sign- hypersensitive facial nerve
Trosseous sign- brachial artery compression
Also called suprarenal glands
Adrenal glands
2 regions of the Adrenal glands
Adrenal cortex
Adrenal medullla
What are the zones of the Adrenal cortex
GFR
Zona Glomerulosa
Zona Fasiculata
Zona Reticulosa
Zona Glomerulosa secretion
Aldosterone
Zona fasciculata secretion
Glucocorticoids (cortisol)
Zona Reticulosa secretions
Androgens
