anterior pituitary

Question 1

anterior pituitary hormones (6)
tropic hormones (4)

Answer 1

follicle stimulating hormone (FSH)

luteinizing hormone (LH)

adrenocorticotropic hormone (ACTH)

thyroid stimulating hormone (TSH)

FLAT = tropic

+

prolactin (PRL)

growth hormone (GH)

Question 2

all anterior pituitary hormones are

Answer 2

protein hormones

Question 3

function of FSH (follicle stimulating hormone)

Answer 3

stimulates gamete production (egg and sperm) by stimulating granulosa cells (female) and sertoli cells (male)

Question 4

function of LSH (luteinizing hormone)

Answer 4

promoted production of gonadal hormones
theca cells
granulosa cells
leydig cells

Question 5

in LH what cells are women

Answer 5

theca and granulosa

Question 6

in LH what cells are male

Answer 6

leydig and sertoli

Question 7

theca cells make what

Answer 7

androgens

Question 8

granulosa cells concert androgens to

Answer 8

estrogen

Question 9

leydig cells make

Answer 9

testosterone

Question 10

function of ACTH (adrenocortitropic hormone)

Answer 10

stimulates adrenal cortex to release cortisol (helps the body to resist stress)

Question 11

regulation of ACTH release

Answer 11

triggered by a faulty rhythm of CRH

internal and external factors including stressors can alter release of CRH

Question 12

function of TSH (thyroid stimulating hormone)

Answer 12

stimulates normal development and secretory activity of thyroid gland

Question 13

what are the thyroid hormones

Answer 13

triiodothyronine T3

thyroxine T4

Question 14

what is the function of PRL (prolactin)

Answer 14

stimulates milk production

Question 15

regulation or PRL

Answer 15

controlled by prolactin inhibiting hormone PIH aka dopamine

Question 16

hypersecretion of prolactin inhibits what

Answer 16

release of gonadotropin releasing hormone (GnRH)

considered natural birth control

Question 17

growth hormone functions
direct actions on metabolism
1. encouraged use of __ for fuel
2. promotes __ synthesis
3. decreases rate of __ storage
4. promotes __ breakdown

Answer 17

1. fat
2. protein
3. glucose
4. glycogen

Question 18

growth hormone
indirect actions on growth
1. mediates growth via growth promoting proteins such as ___

Answer 18

insulin-like growth factors (IGF)

Question 19

growth hormone and insulin-like growth factor promote
1. uptake of nutrients —> __ and ___
2. builds __ and deposits __ matrix
3. major targets - __ and __ muscle

Answer 19

1. dna and proteins
2. collagen and bone
3. bone and skeletal muscle

Question 20

growth hormone hyper secretion results in

Answer 20

gigantism = in children (GH is overly secreted)

acromegaly = in adults (over production of hands and feet)

Question 21

growth hormone hypo secretion results in

Answer 21

pituitary dwarfism - in children

not enough GH to produce body features

lack of GH but body is still proportional
