reproductive system Flashcards
internal genitalia in men
testicles, excretory ducts and the annex glands
tubulus system of the internal genitalia in men
in the seminiferous tubes: spermatozoa -> efferent ducts -> epididymis -> vas deferents -> ecaculating canal (in which the seminal vesicle excretes a fluid) -> urethra (in which the prostate excretes their secrete)
vascularization of the testicle
by the testicular artery (branch of the abdominal aorta)
The 2 layers of the ovary
at the exterior a connective layer:
- coritcal area: ovary follicles
- medullar area: loose connective tissue with blood vessels and nerves
musculature of the uterus
strong musculature of smooth longitudinal, radial and spiraled fibers
cavity presents a mucosa
phases of the menstruation
menstrual stage (1-3d) - proliferative stage (4-14d) - secretory stage (15d-1)
2 functions of the testicles
produces the spermatozoids (spermatogenesis) and secretes androgen hormones
controlled by the gonadatropic hormones of the anterior pituitary
the ovule structure is
a vitelline membrane, cytoplasm and nucleus
corpus lutes produces
progesteron and estrogen
the estrogen hormones are synthesized by
follicular cells, or corpus luteum and placenta during pregancy
the progesterone is secreted by
corpus luteus, by the cortical adrenals and by placenta
the umbilical vessels consists of
two arteries and a vein (goes to the child)
Plazenta secrets which hormones
gonadotropins, prolactin and estrogen
vascularization of the fallopian tubes
ovarian artery and uterine artery
prostate adenoma
frequent urinations (mostly during the nights)
decrease of the urinary pressure
enlargement of the bladder due to urine retention
Vergrößerte Prostatadrüse
