primary ovarian follicle

(2) granulosa cell layer only 1-2 cells thick

secondary ovarian follicle

(2) contains small accumulations of fluid in the intracellular space

tertiary ovarian follicle/Graffian follicle

Contains maturing ovum and ruptures during ovulation

secondary oocyte

A haploid cell resulting from meiosis I in oogenesis, which will become an ovum after meiosis II.

zona pellucida

A thick, transpartent coating/lining rich in glycoproteins that surrounds an oocyte.

follicular antrum

-large cavity between layers of granulosa cells

-contains follicular fluid

fimbriae (of uterine tube)

Egg Release:

Ovary -> ____________ -> Uterine Tube -> Uterus -> Cervix -> Vagina

ampulla (of uterine tube)

(2)

isthmus (of uterine tube)

fundus (of uterus)

body of uterus

major portion of uterus

isthmus (of uterus)

narrowed inferior region

cervix (of uterus)

narrow neck which projects into the vagina inferiorly

internal orifice/internal os

cervical canal

external orifice/external os

urogenital vestibule

located just ventral to the anus

labia majora

the larger outer folds of the vulva

labia minora

the smaller inner folds of the vulva.

mons pubis

a mound of fatty tissue covering the pubic area in women

clitoris

organ of sensitive erectile tissue anterior to the opening of the female urethra

seminiferous tubules/testes

highly coiled

produce sperm

head of epididymis

contains efferent ductules and is located on superior aspect of testis

body of epididymis

(K) coiled tubes pass through the body

tail of epididymis

(I) tubes begin to uncoil to become a single tube called the ductus deferens

vas deferens/ductus deferens

the duct that conveys sperm from the testicle to the urethra

ejaculatory duct

small duct that connects the vas deferens to the urethra

seminal vesicle/seminal gland

-each of a pair of glands that open into the vas deferens near its junction with the urethra

-secrete prostaglandins

prostate gland

adds a chemical fluid to the semen

bulbourethral glands

-a pair of exocrine glands near the male urethra

-secrete a thick, alkaline mucus important in neutralizing acids into the urethra

spermatic cord

extends upward from the epididymis and is attached to each testicle

pampiniform plexus

a network of testicular veins that drain the testes and absorb body heat from the testes and scrotum

inguinal ligament

-anatomical structure forming the base of the femoral triangle

-extends from the anterior superior iliac spine to the pubic tubercle

superficial inguinal rings

triangular openings in the external oblique aponeurosis

deep inguinal rings

-interior openings of the inguinal canals

bulb of penis

the expanded end of the spongy body

HeAd

glans penis

the conical mass of erectile tissue that forms the head of the penis

prepuce

foreskin; loose casing that covers the glans penis; removed by circumcision

corpus spongiosum

(2) surrounds urethra and expands to form glans and bulb

corpora cavernosa

(1) either of two masses of erectile tissue forming the bulk of the penis and the clitoris

primary spermatocytes

(A/B) Diploid cells that undergo meiosis I to form two haploid secondary spermatocytes.

secondary spermatocytes

-haploid cells resulting from the first meiotic division of spermatogenesis

-ready to enter meiosis II

spermatids

(4) four haploid cells that are formed when a diploid reproductive cell divides meiotically

dartos muscle

cremaster muscle

(C, D) the 2 muscles that help to elevate or lower scrotum and testes to ensure sperm survival

tunica vaginalis

The tunica albuginea is covered by a delicate serous membrane called the ___________________.

vulva

external female genitalia; includes the labia, hymen, clitoris, and vaginal orifice
