The penile urethra is derived from which portion of the urogenital sinus?
a cell containing 2 sets of chromosomes are known as _____.
the vesicle of the urogenital sinus develops into what in males and females?
the pelvic portion of the urogenital sinus in females becomes what structure?
the phallic portion of the urogenital sinus becomes what structure in females?
Which duct in the female regresses?
urethral folds become the _____ in females
Testosterone is made by the ____ cells
the genital tubercle becomes the _____ in males
True or False: only one X chromosome is needed for development of a normal ovary
urethral folds become the _____ in males
This hormone causes the development of the testes, conversion of the mesonephric tubule to the efferent ductule, wolffian duct differentiation and also testicular descent
can arise from the pluripotent germ cells that do not migrate properly to the gonadal ridges
the labioscrotal swellings becomes the ____ in males
the presence or absence of what chromosome determines sex
True or False: A deletion of SRY can lead to an XY female.
The presence of what hormone in males leads to the regression of the mullerian duct?
Which hormone causes the formation of the epididymis, vas deferens, seminal vesicles, and ejaculatory ducts?
What regulates the transcription of AMH?
Which internal genitalia duct regresses in the male?
The follicles of the ovary develops from the _____ sex cords.
QuestionAnswer
determination of the gonads occurs during weeks _____ of development
this condition occurs when the urogenital folds fail to fuse properly. causes the urethral opening to be at the tip but located ventrally on the penis
primordial germ cells initially migrate to the _____ ridges
concept held by an individual that the individual is male, female, or ambivalent
the pelvic portion of the urogenital sinus in males becomes the ____ urethra
transcription factor that is important for development of the testes
At _____ of embryonic development, the testes begin making androgens and AMH.
catalyzes the conversion of testosterone to DHT
condition in which an X chromosome is missing producing ovarian dysgenesis with vestigial streak gonads
sex cell
absence of AMH causes development of the _____ into fimbria, fallopian tubes, uterus, the cervix, and upper 3rd of the vagina.
the genital tubercle becomes the _____ in females
What connects the testes to the labioscrotal swellings?
this structure hollows out to form the seminiferous tubules
This hormone causes the conversion of the urogenital sinus into the prostatic and initial phallic urethra, development of prostate and bulbourethral glands, and also causes the dev
Which duct regresses spontaneously in the absence of testosterone?
the labioscrotal swellings becomes the ____ in females
AMH is located on which chromosome?
gene on the Y chromosome that makes TDF (testes determining factor) transcription factor
disparity between genotype and phenotypic sex, as in XX male or XY female
SRY translocation to X chromosome leads to a _____.
Anti mullerian hormone is made by the ____ cells.
True or False: Cryptorchism is incomplete testicular descent
