Reproduction Flashcards
Connects the ovaries to the uterus
Ovarian ligament
Connects The ovaries to the fallopian tubes and the body wall
Suspensory ligament
Attaches to the uterus and the fallopian tube
Broad ligament
Matures to form the ovum
Oocytes
Inner fibrous connective tissue closest to the ovary
Tunica Albuginea
Outer layer with Cuboidal cells that are continuous with the parietal peritoneum
Germinal epithelium
Microscopically the ovaries are composed of many sac-like structures that consist of immature eggs called an oocytes
Ovarian follicles
Transport ova from the ovaries to the uterus… Example oviducts or Fallopian tube… It takes 3 to 6 days for the egg to travel the length of the tube
Uterine tubes
Part of the uterine tube that is the site for fertilization of the egg
Ampulla
Part of the uterine tube which attaches to the curve like structure ampulla serves as a normal site of fertilization of the egg
Infundibulum
Fingerlike projections which posses many cilia and are located at the ends of the uterine tube and partially surround the ovary to receive the egg during ovulation… attaches to the infundibulum
Fimbriae
As the egg reaches the end of the uterine tube it must pass through a narrow region called the?
Isthmus
Paired almond shaped gonads of the female located on each side of the uterus,they produce immature eggs called oocytes, they are covered by two layers of tissue, and are the primary site for egg production, and production of estrogen,progesterone, and inhibin
Ovaries
The uterus consist of three regions… The rounded upper is called?
Funded
The uterus consist of three regions… the major portion of the uterus is called?
The body
The uterus consist of three regions… The narrow neck and mouth of the uterus is called?
The cervix
The cervix poses a passageway that is connected on both ends of the cervical os called?
Implantation in this area causes dilation in the later stages of childbirth and can lead to complications
Cervical canal
The uterine wall is composed of three layers the thick innermost mucous lining where the fertilized egg will penetrate is called the?
This layer is two layers thick… Contains the stratum functionalis and the Stratum basalis
Endometrium
The uterine wall is composed of three layers the muscular middle layer made of smooth muscle for stretch is called the?
Myometrium
The uterine wall is composed of three layers the outermost serous layer is called the?
Perimetrium
The endometrium has two chief strata… The functional zone where spiral arteries deliver nutrient rich blood to this zone is called?
Stratum functionalis
The endometrium has two chief strata… The innermost composed of rapidly dividing cells forms a new functional layer each month… Nourished by straight arteries which delivers blood to the functional zone
Stratum Basalis
A thin walled muscular tube extending from the cervix to the vestibule, functions as the birth canal, possesses Numerous rugae for stretch… is lined with stratified squamous epithelium to protect against abrasions
Vagina
The upper portion of the vagina surrounds the cervix creating in anterior and posterior arch- like passageway
Fornix
An incomplete partition located at the distal end of the vaginal orifice and is often ruptured during the first coitus
Hymen
Also called the vulva or pudenum
External genitalia
Homologous to the bulbourethral glands in the male… Produce secretions during arousal
Vestibular glands
The soft tissue between the vaginal region and the anus, often cut during childbirth in a procedure called episiotomy
Perineum
One function of the male reproductive system is to manufacture ? and to deliver them to the female reproductive track where fertilization can occur
Gametes (sperm)
Produce the gametes and hormones, testes of the male, and ovaries of the female
Gonads
Begin during puberty in males and continues throughout life, occurs in the seminiferous tubules of the testes and generally takes nine weeks
Spermatogenesis
Differentiation of immature male gametes into physical mature sperm called ?
Spermiogenesis
Reference to Each division of a diploid spermatogonium produces 2 daughter cells, one is a spermatogonium that remains in contact with the basil lamina of the tubule and the other is a primary spermatocytes that is pushed towards the lumen of the tubule
Mitosis of spermatogonia
Beginning with each primary spermatocytes containing 46 individual chromosomes at the in the daughter cells are usually called secondary spermatocytes, each secondary spermatocyte contains 23 chromosomes each of which consists of a pair of duplicate chromatids
Meiosis I
The secondary spermatocytes soon enter this phase which use for haploid spermatids each containing 23 chromosomes, for each primary spermatocyte that enters Meiosis, four spermatids are produced
Meiosis II
The spermatids undergo physical maturation to form the spermatozoa, a process which takes approximately 24 days
Spermiogenesis
