TSH
31
More potent thyroid hormone
T3
32
More numerous thyroid hormone
T4
33
Releasing hormones are controlled by the _____ to stimulate cells of Adenohypophysis to secrete hormones
Hypothalamus –– releasing hormones
34
Release of GH
Somatocrinin (go for this✨) or Growth hormone releasing hormone
35
Inhibits release of GH
Somatostatin "SomatoSTOPin"
36
Release of Prolactin
PRH
37
Inhibits prolactin release
Prolactin inhibiting hormone / Dopamine
38
Release of FSH / LH
Gonadotropin releasing hormone
39
Release of ACTH
Corticotropin releasing hormone
40
Release of TSH
Thyrotropin releasing hormone
41
Excessive hormones in the bloodstream will have a _____ on the hypothalamus to prevent disease –– Hypothalamus detects concentration of hormones in the blood to know if it will increase or decrease it
Negative feedback
42
Excessive cortisol
Cushing's syndrome
43
🔹Moon face + Buffalo hump | 🔹Excessive cortisol
Cushing's syndrome
44
Deficient cortisol
Addison's disease
45
What is seen in Addison's disease = deficient cortisol levels
Hyperpigmentations
46
Excessive thyroid hormones
Hyperthyroidism
47
Deficient thyroid hormones
Hypothyroidism
48
Hormone secreted by the hypothalamus neurosecretory cells during puberty
GnRH: Gonadotropin releasing hormone
49
Male GnRH stimulates Adenohypophysis to secrete:
FSH and LH (sa male, sabay yung dalawa)
50
Male: Target cells of FSH - what is produced
FSH - Sertoli cells - ABP
51
Male: | Target cells of LH - what is produced
LH - Leydig cells - Testosterone
52
When testosterone binds to ABP = formation of sperm called
Spermatogenesis
53
Responsible for SECONDARY male characteristics
Tes2sterone
54
Increase levels of testosterone has a negative feedback on what hormones (3)
GnRH LH FSH
55
In females: Menstrual cycle.. Hypo GnRH stimulates Adenohypophysis to secrete what?
FSH
56
How many days is menstrual cycle
28 days
57
Target site of FSH in females
Granulsa cells of Primordial follicle
58
2 parts of Primordial follicle
Oocyte | Granulosa cells
59
Granulosa cells with FSH =
Production of Estrogen
60
Production of Estrogen results to
🔹Primary follicle development 🔹Secondary female charac 🔹Slight thickening of endometrial lining 🔹decline in FSH (negative feedback)
61
2 hormones responsible for Primordial follicle maturation
FSH | Estrogen
62
Mature Primordial follicle
Graafian follicle
63
High ESTROGEN stimulates _____
LH secretion ⬆️E = ⬇️FSH = ⬆️LH
64
LH peak results to _____
Ovulation
65
What day is ovulation4
Day 14
66
Release of egg cell towards falloping tube
Ovulation (bec of LH peak)
67
Ovulation allows maturation of graafian follicle into
Corpus luteum
68
What is produced by corpus luteum
PIE Progesterone Inhibin Estrogen
69
🔹Inhibits FSH 🔹thickens endo lining 🔹stimulates PRH secretion
Progesterone and estrogen
70
Main hormone of corpus luteum for inhibiting FSH
Inhibin
71
Site where zygote is implanted
Endometrial lining
72
Progesterone and Estrogen stimulates PRH secretion to Ant pituitary gland to secrete _____
Prolactin: breasts enlargement = milk production | Increase estrogen and progesterone of corpus luteum = prolactin
73
If fertilization occurs: corpus luteum is
Corpus luteum is maintained
74
After how many days will the embryo be implanted in the endometrial lining
