Gamates | sex cells; sperm or ova |
Gonads | primary sex organs, produce gamates |
Meiosis | cell division in which gamates are produced |
Glans penis | distal portion of penis; high density of nerve endings and area of highest sensitivity in the penis. |
Prepuce (foreskin) | skin covering the glans penis |
Dartos muscle | helps adjust the position of the testes relative to the body to keep the temperature about 2-4 degrees lower than normal body temperature |
Seminiferous tubules | functional unit of the testes; long tubes that produce sperm cells. |
Epididymis | long flattened tubule attached to the superior portion of the testis; functions as a holding area for sperm to mature, transports sperm to ductus deferens |
Spermatic cord | cord connected to the testes; made up of ductus deferens, testicular blood vessels, nerves, cremaster muscle, and lymph vessels. |
Ductus deferens | ciliated tube that conducts sperm from the epididymis to the ejaculatory duct. |
Seminal vesicles | glands located posterior and inferior to the urinary bladder, produce and secrete and alkaline fluid that makes up about 60% of the total volume of semen |
Ejaculatory duct | small duct formed after the union of the ductus deferens and the duct from the seminal vesicle; carries semen to urethra |
Prostate gland | contracts to force semen out during ejaculation; produces alkaline fluid that makes up about 35% of semen volume |
Bulbourethral gland | pea sized; below prostate gland; produces lubricating fluid released on excitation to clear out urine residue, about 3% of semen volume |
Follicle | small cavity in the ovary that stores the ovum; stimulates ovum to mature in response to certain hormones |
Uterine tubes (fallopian tubes) | ciliated tubes that transport ova from the ovaries to the uterus; most common site for fertilization |
Fimbriae | fingerlike projections of the uterine tubes that surround the ovaries; sweep ovum into the open end of the uterine tube. |
Perimetrium (metra=uterus) | outer serosal tissue surrounding the uterus |
Myometrium | middle smooth muscle layer of the uterus |
Endometrium | inner mucosal layers of the uterus; one of these layers, the stratum functionale, is shed every month and becomes the menses |
Fundus of the uterus | bulge at the top of the uterus |
Cervix | inferior portion of the uterus that protrudes down into the vagina |
Cervical canal | opening in the cervix through which sperm travels to fertilize the egg. |
Vestibule | area between the to labia minora where the urethral and vaginal orifices are found |
