Answer 4

Long distance chemical signal that travels in blood/lymph

Question 5

Act locally, but affect different cel types

Question 7

3 type of endocrine glans stimuli

Answer 7

• Neuro
• Altered level of ion/nutrient
• Hormone

Question 8

Cell respons depends

Answer 8

• Heeft de cell de receptor?
• Concentratie
• Aantal receptoren
• Affiniteit

Question 9

Verschillen vet/water oplosbaar

Answer 9

Vet:
- Steroids & throid
- No vesicles
- Bound to plasma protein in blood
- Long half-life in blood
- Receptor in cel
- Activate genes > synthesis proteins

Water:
- Aminozuur (behalve thyroid)
- Vesicles
- vrij in bloed
- Short half-life in blood
- Receptor in membraan
- Activate second messenger system

Question 10

Permissiveness

Answer 10

Interaction
Hormoon kan effect niet compleet uitvoeren zonder bijzijn van ander soort hormoon

Question 11

ADH

Question 14

Anterior pituitary gland

Answer 14

Hypothalamic hormone stimuli
Growth hormone
Thyroid-stimulating hormone
Adrenocorticotopic hormone
Follicle-stimulating hormone
Luteinizing hormone
Prolactin

Question 15

Oxytocin

Answer 15

Posterior pituitary
Stimulated by hypothalamus in respons to stretching of uterine cervix or suckling on breast
inhibited by lack of stimuli

Question 16

Antidurectic hormone (ADH)

Answer 16

Posterior pituitary
Stimulated by impluses hypothalamus in respons to increased concentration in blood/decreased blood volume. Or pain, low bloodpressure
Inhibited by good hydration (or alcohol)
stimlates the kidneys to resorb water back into blood

Question 17

Thyroid-stimulating hormone (TSH)

Answer 17

Anterior pituitary
Stimulated by Thyrotropin-releasing hormone
Inhibited by feedback inhibition & Growth hormone-inhibiting hormone
Stimulates thyroid glands to release thyroid hormones

Question 18

ADrenocorticotropic hormone (ACTH)

Answer 18

Stimulated by corticotropin-releasing hormone (fever, hypoglymia)
inhibited by feedback inhibition by glucocorticoids
Stimulates release of glucocorticoids and androgens

Question 19

Follicle stimulating hormone (FSH)

Answer 19

Stimulated by Gonadotropin-releasing hormone
inhibited by inhibin & estrogens/testosterone
Stimulates follicle maturation, production estrogens & sperm production

Question 20

Luteinizing hormone (LH)

Answer 20

Stimulated by Gonadotropin-releasing hormone
Inhibited by feedback from estrogens & progesteron / testosterone
Stimulates ovulation, estrogen production & testosterone production

Question 21

Prolactin (PRL)

Answer 21

Stimulated by decreased prolactin-inhibiting hormone, release of estrogens, breast-feeding
inhibited by prolactin-inhibiting hormone (PIH) (dopamine)
Stimulates lactation
