| Term | Definition |
| Male Internal Reproductive Organs | Testes
Epididymis
Vas Deferens
Seminal Vesicle
Ejaculatory Duct
Prostate Gland
Bulbourethral Gland |
| Testes: Structure | Paired, bilateral ovoid shaped
suspended by the spermatic cord, contained within scrotum |
| Testes: Function | Produce sperm
Produce testosterone |
| Epididymis: Stucture | Tightly coiled tube that emerges from top of each testis, leads into vas deferens |
| Epididymis: Function | Stores sperm cells until they mature |
| Vas Deferens: Structure | Muscular tube passes along the medial side of the testis into abdominal cavity
makes up the spermatic cord
ends behind urinary bladder |
| Vas Deferens: Function | Transports sperm |
| Seminal Vesicle: Structure | Convoluted, sac-like structure, 5cm long attached to each vas deferens at base of the bladder |
| Seminal Vesicle: Function | secretes slightly alkaline fluid consisting of fructose and other nutrients for sperm cells. Produces 60% of the volume of semen. |
| Ejaculatory Duct: Structure | Short tube (1 inch) beginning at seminal vesicle and ending in the prostate gland |
| Ejaculatory Duct: Function | Transport sperm and seminal fluid to urethra |
| Prostate Gland: Structure | Firm structure the size of a chestnut composed of muscular glandular tissue |
| Prostate Gland: Function | Secretes thin, milky, alkaline fluid which contributes to the motility of sperm |
| Cowper's Glands: Structure | 2 pea-sized glands under the male urethra |
| Cowper's Glands: Function | Provide lubrication during sexual intercourse |
| What is the function of the Vas Deferens? | To transport sperm |
| What is the function of the Epididymis? | Stores sperm cells until they mature. |
| Scrotum: Structure | Sac like structure
2 separate chambers
each chamber encloses a testis |
| Scrotum: Function | Provides a cooler home for the testes |
| Penis: Structure | Shaft is composed of 3 columns of erectile tissue:
(2) Corpora Cavernosa
(1) Corpora Spongiosum |
| Penis: Function | Specialized to become erect for insertion into the vagina during sexual intercourse |
| Ovaries: Structure | Solid, ovoid shaped structures
subdivided into 2 sections
-medulla
-Cortex |
| Ovaries: Location | Lie bilateral to the uterus inferior to fallopian tubes |
| Ovaries: Function | At puberty, they release progesterone and produce the female sex hormone estrogen.
It releases a mature egg cell during the menstrual cycle. |
| Fallopian Tubes (Oviducts): Structure | Pair of ducts
Forms a funnel shaped region near the ovary called the infundibulum.
Infundibulum is surrounded by fringe of finger-like projections called fimbrae. |
| Fallopian Tubes (Oviducts): Function | Cilia along with peristaltic contractions of its wall move the egg cell on to the uterus. |
| Uterus: Structure | Muscular, hollow, shaped like an inverted pear. |
| Layers of the uterine wall | Endometrium
Myometrium
Perimetrium |
| Uterus: Function | Receives and sustains developing fetus.
Capable of enlarging up to 500 times. |
| Vagina: Structure | Thin walled muscular tube-like structure
Lined with mucous membranes |
| Vagina: Function | Receives the erect penis during intercourse
Conveys uterine secretions
Transports offspring during birth |
| What are the 2 sections the ovaries are subdivided into? | Medulla
Cortex |
| Labia Majora: Structure | Large fold of fatty tissue extending from the mons pubis to the perinial floor |
| Labia Majora: Function | Protects inner structures
Contains sensory nerve endings, sebaceous and sudoriferous glands |
| Labia Minora: Structure | Smaller folds, devoid of hair that emerge anteriorly to form the prepuce of the clitoris |
| Labia Minora: Function | Protect the openings of the vagina and urethra. |
| Clitoris: Structure | Composed of erectile tissue |
| Clitoris: Function | Sexual arousal |
| Vestibule: Structure | Space enclosing the structures beneath labia minora |
| Vestibule: Function | Contains the clitoris, urethra, hymen and vaginal opening |
| Accessory Glands | Paraurethral or Skene's Glands
Bartholin's Glands or Vestibular |
| Paraurethral or Skeen's Glands | Responsible for secretion of mucus and are similar to the male prostate gland |
| Bartholin's Glands or Vestibular | Lubricates the vagina for sexual intercourse |
| Perineum | A diamond shaped area from the symphysis pubis and extends to the anus.
Region that contains the reproductive structures. |
| What is the function of the clitoris? | Sexual Arousal |
| What is the function of the Labia Majora? | Enclose and protect other external organs. |
| Mammary Glands: Structure | located in the subcutaneous tissue of the anterior thorax.
Composed of about 15-20 lobes.
Nipple surrounded by the areola |
| Mammary Glands: Function | Specialized to secrete millk following pregnancy.
Under the influence of prolactin, milk is formed.
Oxytocin allows the milk to be released. |
| What is the function of the mammary glands? | To secrete milk following pregnancy |
| T pigment around the nipple is called? | The areola. |
| what is the difference between the peritoneum and the perineum? | One it tis, and one it Taint! |
