REPRODUCTIVE SYSTEM
| Question | Answer |
|---|---|
| THE DARTOS AND CREMASTER MUSCLES ARE IMPORTANT TO THE INTEGRITY OF THE MALE REPRODUCTIVE SYSTEM. WHAT IS TRUE ABOUT THE ROLE THEY PLAY | THEY REGULATE THE TEMPERATURE OF THE TESTES |
| THE ABILITY OF SPERM CELLS TO MOVE ALONG THE DUCTUS DEFERENS IS DUE TO | PERISTALTIC CONTRACTIONS |
| THE ABILITY OF A MALE TO EJACULATE IS DUE TO THE ACTION OF | THE BULBOSPONGIOSUS MUSCLES |
| THE MOST IMPORTANT RISK FOR TESTICULAR CANCER IN YOUNG MALES IS | NONDESCENT OF THE TESTES |
| WHAT GLANDS ARE RESPONSIBLE FOR 60% OF THE SYNTHESIS OF SEMEN | THE SEMINAL VESICLES |
| WHAT HORMONES CONTROL THE RELEASE OF ANTERIOR PITUITARY GONADOTROPINS | GnRH |
| DEVELOPMENT OF MALE REPRODUCTIVE STRUCTURES DEPENDS ON WHICH OF THE FOLLOWING EVENTS | SECRETION OF MALE HORMONES PRENATALLY AND LASTING INTO THE FIRST FEW MONTHS AFTER BIRTH |
| THE PRIMARY FUNCTION OF THE UTERUS IS TO | RECEIVE, RETAIN, AND NOURISH A FERTILIZED OVUM |
| WHY IS THE BLOOD TESTIS BARRIER IMPORTANT | .BECAUSE SPERMATOZOA AND DEVELOPING CELLS PRODUCE SURFACE ANTIGENS THAT ARE RECOGNIZED AS FOREIGN BY THE IMMUNE SYSTEM |
| THE STRUCTURES THAT RECEIVE THE OVULATED OOCYTE PROVIDING A SITE FOR FERTILIZATION ARE CALLED THE | FALLOPIAN TUBES |
| IF GAMETES WERE DIPLOID LIKE SOMATIC CELLS HOW MANY CHROMOSOMES WOULD THE ZYGOTE CONTAIN | TWICE THE DIPLOID NUMBER, AND WITH EVERY SUCCEEDING GENERATION THE CHROMOSOMES NUMBER WOULD CONTINUE TO DOUBLE AND NORMAL DEVELOPMENT COULD NOT OCCUR |
| HUMAN EGG AND SPERM ARE SIMILAR IN THAT | THEY HAVE THE SAME NUMBER OF CHROMOSOMES |
| THE CONSTANCY OF THE CHROMOSOME NUMBER FROM ONE CELL GENERATION TO THE NEXT IS MAINTAINED THROUGH | MEIOSIS |
| FERTILIZATION GENERALLY OCCURS IN THE | FALLOPIAN TUBES |
| SPERMIOGENESIS INVOLVES THE | FORMATION OF A FUNCTIONAL SPERM BY THE STRIPPING AWAY OF SUPERFLUOUS CYTOPLASM |
| ALL OF THE FOLLOWING CAN BE CONSIDERED MALE SECONDARY SEX CHARACTERISTICS EXCEPT THE | DEVELOPMENT OF TESTES AS OPPOSED TO OVARIES |
| IN HUMANS SEPARATION OF THE CELLS AT THE TWO CELL STATE FOLLOWING FERTILIZATION MAY LEAD TO THE PRODUCTION OF TWINS WHICH IN THIS CASE WOULD BE | IDENTICAL |
| CHARACTERISTICS OF THE MATURE SPERM INCLUDE | PRESCENCE OF Y CHROMOSOMES IN APPOXIMATELY HALF THE SPERM |
| HOW DO THE TESTES RESPOND TO EXPOSURE TO EXCESSIVE BODY WARMTH | THEY MOVE AWAY FROM PELVIC ACTIVITY |
| EFFECTS OF ESTROGEN INCLUDE | GROWTH OF THE BREASTS AT PUBERTY |
| SECRETION OF PROGESTERONE STIMULATES | PREPARATION OF MAMMARY GLANDS FOR LACTATION |
| WHAT STATEMENT ABOUT SPERM IS NOT TRUE | THE SPERM MIDPIECE CONSISTS OF MITOCHONDRIA SPIRALED TIGHTLY AROUND CONTRACTILE FILAMENTS OF THE TAIL |
| THE CELLS THAT PRODUCE TESTOSTERONE IN THE TESTIS ARE CALLED | INTERSTITIAL CELLS |
| THE TESTICULAR CELLS THAT CONSTRUCT THE BLOOD TESTIS BARRIER ARE THE | SUSTENCULAR CELLS |
| WHAT OCCURS AS A RESULT OF UNDESCENDED TESTES | INADEQUATE OR NONVIABLE SPERM WILL BE PRODUCED |
| ERECTION OF THE PENIS RESULTS FROM | A PARASYMPATHETIC REFLEX |
| WHAT IS NOT PART OF THE PROLIFERATIVE PHASE OF THE FEMALE MENSTRUAL CYCLE | CORPUS LUTEUM |
| WHAT IS NOT A FUNCTION OF THE VAGINA | SERVES AS A PASSAGEWAY FOR THE PRIMARY ZYGOTE |
| WHAT IS A CORRECT STATEMENT ABOUT MALE SEXUAL RESPONSE | ERECTION IS THE RESULT OF VASCULAR SPACES IN THE ERECTILE TISSUES FILLING WITH BLOOD. |
| WHAT IS NOT A FUNCTION OF TESTOSTERONE | STIMULATES MAMMARY GLAND DEVELOPMENT |
| WHICH MALE HORMONE INHIBITS THE SECRETION OF FSH | INHIBIN |
| DURING SECRETORY PHASE OF THE MENSTRUAL CYCLE_______ | PROGESTERONE LEVELS ARE AT THEIR HIGHEST |
| WHAT IS A CORRECT STATEMENT ABOUT THE UTERINE CYCLE | IF FERTILIZATION OCCURS THE CORPUS LUTEUM IS MAINTAINED BY A HORMONE SECRETED BY THE DEVELOPING EMBRYO |
| WHAT IS NOT PART OF THE BRAIN TESTICULAR AXIS | TESTES |
| WHAT IS A TRUE STATEMENT ABOUT MAMMARY GLANDS OF BOTH MALES AND FEMALES | THE MAMMARY GLANDS ARE MODIFIED SWEAT GLANDS THAT ARE ACTUALLY PART OF THE INEGUMENTARY SYSTEM |
| NORMALLY MENSTRUATION OCCURS WHEN | BLOOD LEVELS OF ESTROGEN AND PROGESTERONE DECREASE |
| THE BASIC DIFFERENCE BETWEEN SPERMATOGENESIS AND OOGENESIS IS THAT | IN OOGENESIS ONE MATURE OVUM IS PRODUCED AND IN SPERMATOGENESIS FOUR MATURE SPERM ARE PRODUCED FROM THE PARENT CELL |
| OCCASIONALLY THREE POLAR BODIES FOUND CLINGING TO THE MATURE OVUM ONE CAME FROM UNEQUAL DIVISION OF THE OVUM BUT FROM WHERE DID THE OTHER TWO ARISE | .THE FIRST POLAR BODY HAS ALSO DIVIDED TO PRODUCE TWO POLAR BODIES |
| WHAT WILL OCCUR AFTER OVULATION | THE ENDOMETRIUM ENTERS ITS SECRETORY PHASE |
| WHY DOESNT SEMEN ENTER THE URINARY BLADDER DURING EJACULATION | THE SMOOTH MUSCLE SPHINCTER AT THE BASE OF THE URINARY BLADDER CLOSES |
| SPERMATOGENESIS________ | INVOLVES A KIND OF CELL DIVISION LIMITED TO THE GAMETES |
| WHICH HORMONE IS ABSOLUTELY NECESSARY FOR OVULATION TO OCCUR | LH |
| THE BRAIN TESTICULAR AXIS______ | INOLVES FSH AND LH RELEASE |
| WHAT IS A CORRECT STATEMENT ABOUT TESTOSTERONE CONTROL | GnRH FROM THE HYPOTHALMUS CAUSES FSH AND LH RELEASE FROM THE ANTERIOR PITUITARY |
| WHAT IS A CORRECT STATEMENT ABOUT UTERINE TUBES | THE INFUNDIBULUM IS THE FUNNEL SHAPED REGION NEAR THE OVARY |
| WHAT IS A CORRECT STATEMENT ABOUT HORMONAL EVENTS OF THE OVARIAN CYCLE | HIGH ESTROGEN LEVELS RESULT IN A SURGE OF LH RELEASE |
| WHAT IS A FALSE STATEMENT ABOUT SEXUALLY TRANSMITTED INFECTIONS | SYPHILIS IS CAUSED BY A VIRUS THAT MAY LEAD TO DEATH IF UNTREATED |
| IS THE FOLLOWING STATEMENT ABOUT SPERMATOGENISIS TRUE OR FALSE | EACH SPERMATID FORMS TWO SPERM |
| A BOY WHO HAS NOT PASSED THROUGH PUBERTY SUSTAINS AN INJURY TO HIS ANTERIOR PITUITARY SUCH THAT FSH IS NO LONGER RELEASED, BUT LH IS NORMAL. AFTER HE GROWS TO MATURITY ONE WOULD EXPECT THAT HE WOULD____ | BE STERILE |
| WHAT IS NOT A TRUE STATEMENT ABOUT THE FEMALE REPRODUCTIVE PROCESS | REBUILDING THE ENDOMETRIUM IS UNDER THE CONTROL OF PROLACTIN |
| A LOW SECRETION OF LUTEINIZING HORMONE (LH) IS THE NORMAL MALE ADULT WOULD CAUSE | DECREASED TESTOSTERONE SECRETION |
| THE ____ PLEXUS OF TESTICULAR VEINS ASSISTS IN THE COOLING OF THE TESTIS | PAMPINIFORM |
| SURGICAL CUTTING OF THE DUCTUS DEFERENS AS A FORM OF BIRTH CONTROL IS CALLED A | VASECTOMY |
| THE MIDPIECE OF THE SPERM TAIL CONTAINS MOSTLY | MITOCHONDRIA |
| THE _____ CELLS OF THE TESTIS NOURISH THE NEWLY FORMED SPERM CELLS | SUSTENTACULAR |
| THE SUSPENSORY LIGAMENT AND MESOVARIUM ARE PART OF THE____LIGAMENT | BROAD |
| A FOLLICLE WITH ONLY A SMALL ANTRUM IN IT WOULD BE CLASSIFIED AS A______FOLLICLE | SECONDARY |
| THE SMALL OPENING OF THE UTERUS THAT SPERM WOULD FIRST ENTER IS CALLED THE | EXTERNAL OS |
| THE PORTION OF THE UTERINE ENDOMETRIUM THAT IS NOT SLOUGHED OFF EVERY MONTH IS CALLED THE | STRATUM BASALIS |
| _____ IS CAUSED BY TREPONEMA PALLIDUM | SYPHILIS |
