the cortex

what happens to the endometrium during the menstral phase? This occurs due to what?

the surface layer of the endometrium - statum functionale is peeling off from the stratum basale. This phase is due to the decline of both estrogen and progesterone

ciliated: wave towards the uterus; nonciliated (peg cells): secrete fluid for the ovum

during pregnancy what does estrogen, progesterone sitmulate? E-LD vs PA think about females breast during pregnancy

estrogen stimulates growth of lactiferous duct progesterone stimulates growth of alveoli

what are the contents of the secretions of the prostate

fibrinolysin, citric acid, serine protease (prostate-specific antigen, PSA) and acid phosphate

what are the concentration of the semen of fluid? and sperm?

functional and basal layer functional layer changes helicine {coiled} arteries

where are prostatic concretions frequently found

in the lumen of the prostate

what are the histological difference in an inactive vs active mammy gland

inactive= more connective tissue, less lobules,epithelial cells of ducts are columnar, visible lymphocytes and myoepithelial cells active=less connective tissue, more lobules, secretory alveolar cells are cuboidal, visible myoepithelial cells and plasma cells

what is the function of prolactin

induces leydig to express LH receptors

what muscles of the ductus deferens is responsibile for ejaculation "IOC"

inner longitudial muscle outer longitudial muscle circular muscle

what is another name for leydig cells

interstitial cells

what happens to the corpus luteum when egg doesnt implant

it becomes corpus albicans

what is a secondary follicular cell

it has the following: - granulosa cells {GC}; - antrum {A}; - theca interna {TI}; - theca externa {TE}

what are the bulbourethral gland "cowpers gland" made of? what does it secrete?

-compound tubuloalveolar gland -simple columnar mucus secreting cells -secretes preseminal fluid

what part of the ductus deferens join with the seminal vesicle

ampulla

what is the epithelium that covers the tunica albuginea of the ovary? what is it histological make up?

-germinal epithelium -simple squamous to cuboidal

why is panpanicolau "pap"smear performed and what is done/evaluated?

-performed as part of routine gynecological examination to examine stained exfoliative cells of the lining of the cervix and vagina

what are the three layers of the uterine tubes and describe each?

-serous {peritoneum} -muscularis {inner circular & outer longitudinal smooth muscles} -mucosus {folds with simple columnar epithelium w/o cilia}

what is the clinical correlation of benign prostatic hypertrophy?

-urethral lumen constricted due to the proliferation of the glandular epithelial cells -proliferation is related to the action of dihydrotestosterone (DHT)

what are the functions of sertoli cell

- nourish the developing sperm cells through the stages of spermatogenesis - act as phagocytes, consuming the residual cytoplasm during spermatogenesis.

describe the 4 points of spermatid phase "G-CAM"

-Golgi phase: form acrosomal vesicle; -Cap phase: form acrosomal cap; -Acrosome phase: form manchette; -Maturation phase: Sertoli cells phagocytose excess cytoplasm and release sperm cells.

describe the 4 points of spermatogonial phase

-Stem cells divide to keep population (mitosis); -Type A dark (Ad): stem cells; -Type A pale (Ap): after mitotic divisions; -Type B: ready to be the primary spermatocyte after another mitotic division.

what are the 3 phases of spermatogenesis "I'm gonna, I see it my sights, I did it kid"

1)Spermatogonial phase {mitosis} 2)Spermatocyte phase {meiosis} 3)Spermatid phase {spermiogenesis}

what substance does sertoli secrete and describe

1)anti-Müllerian hormone (AMH) - secreted during the early stages of fetal life to develop male characteristics. 2)inhibin secreted after puberty, and work together to inhibit FSH secretion 3)androgen binding protein (also called testosterone binding globulin) - maintain the level of testosterone and dihydrotestosterone concentration in the seminiferous tubules to stimulate spermatogenesis

Secreted by growing oocyte;Rich in glycosaminoglycons and glycoprotens;

what cells of the testis seminiferous epithelium goes through mitosis to form the primary spermatocytes

Type B

what hormone is being secreted during the secretory phase what is happening to the endometrium and what structure is causing this?

progesterone The endometrium becomes more than twice as thick as in the follicular phase.The uterine glands (arrow) increase in length and become tortuous and sacculated. corpus leuteum is secreting the hormone

what hormone regulats the proliferative stage? secretory phase? what is the menstrual phase?

proliferative=estrogen {days 5-14} secretory=progesterone (days 14-28} menstral phase becomes ischemic due to decline in progesterone and estrogen {days 1-5}

what contained in semen may influence sperm transit and implantation of a fertilized ovum

prostaglandins

what type of epilthelium does the ductus deferens have? how many smooth muscle layers " ducts walk in a column"

pseudostratified columnar epithelium 3 smooth muscle layers

pseudostratified columnar with sterocilia -sperm cells in the middle, the "dark points" are the head, the "strings" are the stereocilia

what is the histological make up of the epididymis epithelium

pseudostratified stereociliated epithelium

what cells in the males are considered true epithelium? false epithelium

sertoli cells {sustentacular cells} sperm cells

what forms the blood testis barrier

what is the epithelium of the uterus made of

simple columnar

what is the epithelium of the cervix made of

simple columnar {SCE} and stratified squamous {SSE}
