Male Reproductive System Flashcards
propagate germ cells by development of haploid spermatozoa in the testes and delivery of the spermatozoa to the female reproductive tract
male reproductive system
The male reproductive tract consists of
the gonads (testes), the tubular genitalia (epididymis, ductus deferens and urethra) and the external genitalia (penis and scrotum).
The main functions of the male reproductive system;
to produce spermatozoa, androgens (sex hormones - principally testosterone) and to facilitate fertilisation, by introducing spermatozoa into the femal genital tract (copulation).
The male reproductive system includes
the testis, genital ducts, accessory sex glands and penis.
glands that provide secretions that form the seminal plasma.
accessory sex glands
Long conduit that conveys spermatozoa to the urethra
ductus deferens
Tubules that connect the efferent ductules to the epididymis
efferent ductules
The coiled network of tubules that are responsible for sperm storage prior to ejaculation
epididymis
Cells within the interstitium between seminiferous tubules that produce testosterone.
leydig cells
Embryonic precursors to the male tubular genitalia
mesonephric ducts
Embryonic precursors to the female tubular genitalia
paramesonephric duct
The tubular structures in which spermatogenesis takes place
seminiferous tubules
Cells within the seminiferous tubule that support spermatogenesis and form the blood-testes barrier
Sertoli cells
the process in which immature germ cells turn into spermatozoa.
spermatogenesis
the process in which a spermatid is converted into a spermatozoa.
spermiogenesis
