Here are a few simple questions that relate to your BGD practical, this page is not a part of today's Practical class. You should try in your own time after completing the Practical today.Take the quiz and see what you know, if you get some wrong, try working through through the BGDB Practical - Sexual Differentiation.

Take the Quiz



Sex determination occurs initially through the SRY transcription factor acting on:

primordial germ cells
anterior pituitary
testes support cells
ovary support cells
mesonephric duct cells


The lower end of the mesonephric duct branches to form the:

ureteric bud
uterus bud
urethral bud
gonadal bud
none of the above


The sequential development of the renal structures within intermediate mesoderm can best be described as:

pronephros, mesonephros, metanephros
pronephros, metanephros, mesonephros
mesonephric duct, metanephros, mesonephros
mesonephric duct, paramesonephric duct, metanephros
uteric bud, ureter, urinary bladder


The sequential development of the genital system can best be described as:

internal and external genital tract dependent upon primordial germ cell hormone secretion
gonadal differentiation and hormone secretion determining internal then external tract development
mesonephric duct hormone secretion forming genital ridge then internal and external tract development
internal tract determining gonadal then hormone secretion for external tract development
paramesonephric duct forming genital ridge then hormone secretion for internal and external tract development


The allantois, cloaca, hindgut and yolk sac are all lined with endoderm



The cells in the adult male and female gonad forming from equivalent primordial cells in each sex are:

Sertoli cells and thecal cells
Leydig cells and interstitial cells
primordial germ cells and oocytes
thecal cells and interstitial cells
ductus deferens and mesonephric ducts


Select the correct options below for the embryonic contribution to the female uterus and vagina

Wolffian duct
Utereric duct
Mullerian duct
paramesonephric duct
urogenital sinus


The relative movement of organs with the peritoneal cavity can best be described as:

descent of the adrenal glands and gonads
ascent of the adrenal glands and genital tubercle
ascent of the kidneys and descent of the gonads
descent of the kidneys and adrenal glands
none of the above


The genital tubercle and inner genital folds form the same adult structures in both sexes.



Select the correct options below describing aspects of gonad development

testis cortical and ovary medullary
ovary cortical and testis medullary
prenatal meiosis in the ovary germ cells
prenatal meiosis in the testis germ cells
prenatal mitosis in the ovary germ cells
