Exercise 42: Anatomy of the Reproductive System
front 1 LIST THE TWO PRINCIPAL FUNCTIONS OF THE TESTIS. | back 1 1. PRODUCE SPERM
|
front 2  | back 2  |
front 3 A COMMON PART OF ANY PHYSICAL EXAMINATION OF THE MALE IS PALPATION OF THE PROSTATE. HOW IS THIS ACCOMPLISHED? (THINK!) | back 3 PHYSICIAN GENTLY INSERTS FINGER THROUGH THE ANTERIOR WALL OF THE RECTUM. |
front 4 HOW MIGHT ENLARGEMENT OF THE PROSTATE INTERFERE WITH URINATION OR THE REPRODUCTIVE ABILITY OF THE MALE? | back 4 AT IT ENLARGES, LAYERS OF TISSUE SURROUNDING IT STOPS IT FROM EXPANDING CAUSING THE GLAND TO PRESS AGAINST THE URETHRA. THIS CONSTRICTION OF THE URETHRA MAY LEAD TO NON PASSAGE OF URINE OR SPERM. |
front 5 WHY ARE THE TESTES LOCATED IN THE SCROTUM RATHER THAN INSIDE THE VENTRAL BODY CAVITY. | back 5 THE SCROTUM PROVIDES A SLIGHTLY COOLER TEMPERATURE FOR OPTIMAL SPERM PRODUCTION. |
front 6 COPULATORY ORGAN/PENETRATING DEVICE | back 6 E. PENIS |
front 7 MUSCULAR PASSAGEWAY CONVEYING SPERM TO THE EJACULATORY DUCT; IN THE SPERMATIC CORD | back 7 B. DUCTUS (VAS) DEFERENS |
front 8 TRANSPORTS BOTH SPERM AND URINE | back 8 K. SPONGY URETHRA |
front 9 SPERM MATURATION SITE | back 9 C. EPIDIDYMIS |
front 10 LOCATION OF THE TESTIS IN ADULT MALES | back 10 I. SCROTUM |
front 11 LOOSE FOLD OF SKIN ENCIRCLING THE GLANS PENIS | back 11 F. PREPUCE |
front 12 PORTION OF THE URETHRA BETWEEN THE PROSTATE AND THE PENIS | back 12 D. MEMBRANOUS URETHRA |
front 13 EMPTIES A SECRETION INTO THE PROSTATIC URETHRA | back 13 G. PROSTATE |
front 14 EMPTIES A SECRETION INTO THE MEMBRANOUS URETHRA | back 14 A. BULBOURETHRAL GLANDS |
front 15 DESCRIBE THE COMPOSITION OF SEMEN, AND NAME ALL STRUCTURES CONTRIBUTING TO ITS FORMATION. | back 15 SPERM AND THE ALKALINE SECRETIONS OF THE PROSTATE, SEMINAL VESICLES (ALSO CONTAINING FRUCTOSE) AND THE BULBOURETHRAL GLANDS. |
front 16 OF WHAT IMPORTANCE IS THE FACT THAT SEMINAL FLUID IS ALKALINE? | back 16 IT HELPS BUFFER THE SPERM AGAINST THE ACID ENVIRONMENT OF THE FEMALE REPRODUCTIVE TRACT. |
front 17 WHAT STRUCTURES COMPOSE THE SPERMATIC CORD? | back 17 CONNECTIVE TISSUE SHEATH (EXTENSION OF THE ABDOMINAL FASCIA), DUCTUS DEFERENS, BLOOD VESSELS, AND LYMPHATIC VESSELS. |
front 18 WHERE IS IT LOCATED? (SPERMATIC CORD) | back 18 PASSES FROM SCROTAL SAC THROUGH THE INGUINAL CANAL INTO THE ABDOMINAL CAVITY. |
front 19 TRACE THE PATHWAY OF SPERM FROM THE TESTS TO THE URETHRA | back 19 SEMINIFEROUS TUBULE -> RETE TESTIS -> EPIDIDYMIS -> DUCTUS DEFERENS |
front 20 NAME THE STRUCTURES COMPOSING THE EXTERNAL GENITALIA, OR VULVA, OF THE FEMALE. | back 20 MONS PUBIS, LABIA MAJORA, LABIA MINORA, CLITORIS, URETHRA AND VEGINAL ORIFICES, HYMEN AND GREATER VESTIBULAR GLANDS. |
front 21  | back 21  |
front 22 SITE OF FETAL DEVELOPMENT | back 22 UTERUS |
front 23 COPULATORY CANAL | back 23 VAGINA |
front 24 EGG TYPICALLY FERTILIZED HERE | back 24 UTERINE (FALLOPIAN) TUBE |
front 25 BECOMES ERECT DURING SEXUAL EXCITEMENT | back 25 CLITORIS |
front 26 DUCT EXTENDING SUPEROLATERALLY FROM THE UTERUS | back 26 HYMEN |
front 27 PRODUCES OOCYTES, ESTROGENS, AND PROGESTERONE | back 27 OVARIES |
front 28 FINGERLIKE ENDS OF THE UTERINE TUBE | back 28 FIMBRIAE |
front 29 DO ANY SPERM ENTER THE PELVIC CAVITY OF THE FEMALE? WHY OR WHY NOT? | back 29 YES, BECAUSE THERE IS NO ANATOMIC CONTINUITY BETWEEN THE OVARY AND THE FIRST PART OF THE DUCT SYSTEM (UTERINE TUBE) |
front 30 WHAT IS AN ECTOPIC PREGNANCY, AND HOW CAN IT HAPPEN? | back 30 IT IS WHEN AN EMBRYO IMPLANTS IN A SITE OTHER THEN THE UTERUS. IT MAY OCCUR WHEN THE UTERINE (FALLOPIAN) TUBES ARE BLOCKED (PREVENTS PASSAGE) OR WHEN THE EGG IS LOST IN THE PERITONEAL CAVITY AND FERTILIZATION OCCURS THERE. |
front 31 PUT THE FOLLOWING VESTIBULAR PERINEAL STRUCTURES IN THEIR PROPER ORDER FROM THE ANTERIOR TO THE POSTERIOR ASPECT: VAGINAL ORIFICE, ANUS, URETHRAL OPENING, AND CLITORIS. | back 31 ANTERIOR LIMIT: CLITORIS -> URETHRAL OPENING -> ANUS. |
front 32 ASSUME A COUPLE HAS JUST CONSUMMATED THE SEX ACT AND THE SPERM HAVE BEEN DEPOSITED IN THE VAGINA. TRACE THE PATHWAY OF THE SPERM THROUGH THE FEMALE REPRODUCTIVE TRACT. | back 32 VAGINA -> CERVIX -> UTERUS -> UTERINE TUBE -> PERITONEAL CAVITY. |
front 33 DEFINE OVULATION. | back 33 EJECTION OF AN IMMATURE EGG (OOCYTE) FROM THE OVARY. |
front 34 THE TESTIS IS DIVIDED INTO A NUMBER OF LOBES BY CONNECTIVE TISSUE. EACH OF THESE LOBES CONTAINS ONE TO FOUR _____1________, WHICH CONVERGE TO EMPTY SPERM INTO ANOTHER SET OF TUBULES CALLED THE _____2_________. | back 34 1. SEMINIFEROUS TUBULES
|
front 35 WHAT IS THE FUNCTION OF THE CAVERNOUS BODIES SEEN IN THE PENIS? | back 35 THE TISSUE CAN BECOME ENGORGED WITH BLOOD, THIS MAKING THE PENIS STIFF AND MORE EFFECTIVE AS A PENETRATING DEVICE. |
front 36 NAME THE THREE LAYERS OF THE UTERINE WALL FROM THE INSIDE OUT. | back 36 ENDOMETRIUM, MYOMETRIUM, PERIMETRIUM (SEROSA) |
front 37 WHICH OF THESE IS SLOUGHED DURING MENSES? | back 37 ENDOMETRIUM |
front 38 WHICH CONTRACTS DURING CHILDBIRTH? | back 38 MYOMETRIUM |
front 39 WHAT IS THE FUNCTION OF THE STEREOCILIA EXHIBITED BY THE EPITHELIAL CELLS OF THE MUCOUS OF THE EPIDIDYMIS? | back 39 TO ABSORB EXCESS FLUID AND PROVIDE NUTRIENTS TO THE MATURING SPERM. |
front 40  | back 40  |
