Hsci Human Anatomy Iii ( Hsci 107)

Course:Nursing Sciences

Institution: Kenya Methodist University question papers

Exam Year:2011

TIME : 3 HOURS

Instructions:
Answer ALL the questions in the booklet provided
SECTION A: Multiple choice questions, answer T or F and match correct response where appropriate

Question one
Match the following statement with original response in column B
Female or germ cell produced in the ovaries
Results form fusion of oocyte and sperm. It’s the beginning of new human being
Occurs 3-4days after fertilization just as the developing human enters the uterus
Fluid filled cavity with centrally located cells-inner cell mass
Refers to the developing human during its early stages of development
Column B
Oocyte
Embryo
Morula
Zygote
Blastocyst
Gastrula
Fetus

Question Two
The following are developmental stages
Childhood
Neonatology
Adulthood
Adolescence
Pediatrics

Question Three
Organs of reproduction include the following
Fallopian tubes
Uterus
Scrotum
Bladder
Testes

Question Four
Stages of embryology include the following
Ovulation
Fertilization
Implantation
Morula formation
Gastrulation

Question Five
In the ancient times as regards history of embryology, the founders were
Aristotle of Stagira
Hippocrates of cos
Claudius galen
Leonardo da vinci
Constantinus africanus of salerno

Question Six
As regards meiosis
There are two meiotic cell divisions
Anaphase and inter phase occur in second meiotic division
Diploid germ cells give rise to haploid gametes
There is a normal inter- phase between first division and second division of meiosis
In second meiotic division the haploid number of chromosomes is retained

Question Seven
About the female reproductive system
Uterus averages 7 to 8cm in length and 5 to 7cm in width at its superior part, 2 to 3cm in thickness
Hypothalamic stimulation results in release of hormones significant in menstruation
Pelvis is sometimes divided into true pelvis and false pelvis
True pelvis and false pelvis is separated by a pelvic inlet
The normal transverse diameter is 13.5cm and is wider than the anterior-posterior diameter which is 11cm

Question Eight
In females, oocytes are produced by
Ovaries
Uterine tubes
Testes
Pelvis
Uterus

Question Nine
Enzymes involved in fertilization include
Acrosin
Hyaluronidase
Esterase
Lipase
Polymerase

Question Ten
Following occur in the 1st week of embryonic development
Fusion of female and male gametes
Cleavage of the zygote
Morula formation
Blastogenesis
Neural tube formation

Question Eleven
Development of ovarian follicles is characterized by
Growth and differentiation of a primary oocyte
Proliferation of follicular cells
Formation of zona pellucida
Development of a connective tissue capsule, the theca folliculli
None of the above

Question Twelve
Regarding uterine tubes
Are 10 to 12cm long and 1cm in diameter, extend laterally from the horns of the uterus
Carry oocytes from the ovaries and sperms entering from the uterus to reach the fertilization site in the ampulla
Conveys the dividing zygote to the uterine cavity
Its finger like projections at the infindubulum known as fimbriae act by sweeping action to pass the mature ovum into the tube
None of the above

Question Thirteen
About ovulation
Occurs around midcycle 14th day of average 28day cycle
Occurs under the influence of FSH and LH
Is triggered by a surge of LH production following LH peak by 12-24hours
LH surge is elicited by high estrogen levels in blood
All above are TRUE

Question Fourteen
About menstrual cycle
Period during which oocytes matures, ovulated and enters the uterine tube
Also known as endometrial cycle
Normal endometrium is a mirror of the ovarian cycle due to response in consistency with fluctuating concentration of hormones
Average cycle is 28 days
90% of women, length of cycles ranges between 23 and 35 days

Question Fifteen
Concerning sperm transport
Sperms pass by the accessory glands
Accessory sex glands include seminal vesicles, bulbo-urethral glands and prostate gland
200-600 millions of sperms are deposited around the external Os of the cervix
Reflex ejaculation of sperms may be divided into emission and ejaculation
Ejaculate averages 3-5mls with a range of 2-3mls

Question Sixteen
Sperms move 2 to 3 per minute depending on pH
Sperms account for less than 10% of semen 60% of seminal,vesicles; 30% prostate gland;10% in bulbo-urethral glands
It is denoted by semen containing 20million sperms per ml or 50million in total specimen
40% of sperms should be motile after 2hours and others after 24hrs
Causes of infertility include: endocrine disorders; abnormal spermatogenesis or obstruction of genital ducts

Question seventeen
The following processes occur in second week of development
Rapid proliferation and differentiation of trophoblasts
Decidual reaction
Development of the yolk sac
Development of amniotic cavity
Development of primary endoderm

Question Eighteen
Development of an ovarian follicle is characterized by
Growth and differentiation of primary oocyte
Proliferation of follicular cells
Formation of zona pellucida
Development of a connective tissue capsule, the theca folliculli
All are false

Question Nineteen
Testosterone is produced by
Leydig cells
Sertoli cells
Somniferous tubules
Epididymis
Vas deferens

Question Twenty
Indicate true or false in the following statements
Syncytiotrophoblast of the chorion secretes HCG hormone
Corpus luteum secretes progesterone and estrogen only
Implantation occurs in the fallopian tubes
Normal endometrium is a mirror of the ovarian cycle
90% of women have a normal ovulatory cycle
