Flashcards in Endocrine anatomy (chiro essentials pg29-31) Deck (41):
1

What gland is considered the master endocrine gland

Pituitary gland

2

What are the embryological origins of the pituitary gland

Rathke's pouch
part of the Hypothalamus

3

Where can you find the pituitary gland

In the sella tursica of the sphenoid bone

4

What covers the pituitary gland

a fold of dura called Diaphragm sellae

5

what does the anterior portion of the pituitary gland produce

FSH
LH
ACTH
TSH
prolactin
GH

6

What influences the release/inhibition of hormones from the anterior pituitary (all except prolactin)

Hypothalamus

7

What influences the release/inhibition of prolacin from the anterior pituitary

Prolactin inhibiting factor (dopamine)

8

What does the posterior pituitary do

Stores hormones (oxytocin + ADH)

9

What produces Oxytocin

Paraventricular nuclei of hypothalamus

10

What produces ADH

Supraoptic nuclei of the hypothalamus

11

What links the two lobes of the thalmus

isthmus

12

What gives blood supply to the thyroid gland

Superior thyroid artery
Inferior thyroid artery
Thyroid ima

13

what types of cells secrete T3 (thyroxin) in the thalamus

Cuboidal cell-lined follicles

14

What cells produce calcitonin in the thalamus

Parafollicular cells

15

What gives blood supply to the parathyroid gland

Inferior thyroid artery

16

What are the two types of cells of the parathyroid gland

Chief cells
Oxyphils

17

What cells secrete PTH

Chief cells

18

What does PTH do

Takes calcium out of bone and into the blood stream

19

Wha organ is both an exocrine and endocrine gland

Pancreas

20

What is the pancreas derived from

Ventral and dorsal endodermal buds from the foregut

21

What cells are found in the pancreas

Alpha 20%
Beta 75%
Delta 5%

22

What pancreatic cells secrete insulin

Beta cells

23

alpha cells

24

What pancreatic cells secrete somatostatin

Delta cells

25

what are the parts of the pancreas

Head
neck
body
tail

26

Which pancreatic duct carries exocrine juices from the tail body and neck of the pancreas

Main pancreatic duct

27

what does the main pancreatic duct join up with

Common bile duct

28

What does the main pancreatic duct and the common bile duct open into

Ampulla of vater

29

Where is the ampulla of vater

The duodenum

30

What pancreatic duct drains the head

accessory pancreatic duct

31

What gives blood supply to the pancreas

Superior pancreaticoduodinal artery
inferior pancreaticoduodinal artery
great pancreatic artery

32

What are the adrenal glands derived from

Cortex (outter) = mesoderm
Medulla (inner) = Neural crest cells

33

Which adreanl gland is larger

The right one, it is also triangle shaped

34

What are the three structural zones in the cortex of the adreanal glands

Glomerulosa
Fasciculata
Reticularis

35

What does the Glomerulosa of the adreanal gland secrete

Aldosterone (under renin control)

36

What does the Glucocorticoids of the adreanal gland cortex secrete

Glucocorticoids (under ATCH control)

37

What does the Reticularis of the adrenal gland cortex secrete

40

What drains the left adrenal gland

Left renal vein

41

What drains the right adrenal gland

Inferior vena cava
