Flashcards in 3. Pituitary gland Deck (23):
1

anterior pituitary ( adenohypophysis) is derived from

oral ectoderm ( Rathke pouch)

2

anterior pituitary ( adenohypophysis( secretes

1. FSH
2. LH
3. TSH
4. hCG
β subunit determines their hormone specificity

3

posterior pituitary ( neurohypophysis ) secretes

1. vasopressin ( ADH)
2. oxytocin

4

vasopressin and oxytocin are made in .... (exactly )

hypothalamus:
vasopressin --> supraoptic nuclei of hypothalamus
oxytocin ---> paraventricular nuclei of hypothalamus

5

vasopressin and oxytocin production and secretion ( where and transportation )

made in hypothalamus ( supraoptic and paraventricular nuclei ) and transported to posterio pituitary via neurophysis

6

hornone made in paraventricular nuclei of hypothalamus

oxytocin

7

vasopressin is made in

supraoptic nuclei of hypothalamus

8

oxytocin is made in

paraventricular nuclei of hypothalamus

9

foramen cecum is

normal remnant of thyroglossal duct

10

pyraidal love of thyroid

persistent thyroglossal duct

11

Melanotropin ( MSH ) is secreted by

intermediate lobe of thyroid

12

lingual thyroid - management

may result in hypothyroidism if it is the only thyroid tissue present

13

ACTH and MSH are derivatives of

propiomelanocortin

14

adenohypophysis cells are divided to ...- what the secrete

basophils : 1. FSH 2. LH 3. ACTH 4. TSH
acidophils : 1. GH 2. PRL

15

16

pituitary - embryology

adenohypophysis --> oral ectoderm ( Ratgke pouch)
neurohypophysis --> neuroectoderm

17

Name the embryologic origins of the anterior and posterior pituitary.

Oral ectoderm (Rathke pouch) and neuroectoderm, respectively

18

• What hormones does the posterior pituitary secrete? Where are these hormones made, and how are they transported?

Vasopressin (antidiuretic hormone) and oxytocin; made in hypothalamus; shipped to posterior pituitary via carrier proteins (neurophysins)

19

• Which pituitary hormones have a common α subunit? What is the significance of the β subunit?

Thyroid-stimulating, luteinizing, follicle-stimulating, human chorionic gonadotropin hormones; determines hormone specificity

20

• Your patient has a tumor in his anterior pituitary gland that affects all hormones produced there. Which hormones would be affected?

Follicle-stimulating (FSH), luteinizing (LH), ACTH, thyroid-stimulating (TSH), Prolactin, growth hormone (GH) (FLAT PiG)

21

• Which anterior pituitary hormones are secreted from acidophilic cells? Which are secreted from basophilic cells?

Acidophils secrete GH and prolactin; Basophils secrete FSH, LH, ACTH, and TSH (B-FLAT)

22

• A woman sustains a traumatic brain injury. MRI shows anterior pituitary damage in the intermediate lobe. What hormone dysfunction may occur?

Melanotropin (MSH) is secreted from here, and the patient may have problems with skin pigmentation in the future

23

• Before being transported to the posterior pituitary, oxytocin is made in the ____ and vasopressin in the ____.

Paraventricular nucleus of the hypothalamus; supraoptic nucleus of the hypothalamus
