  • testes

    -produce male sex androgens, mainly testosterone.

  • internal accessory organs

    -produce the fluid constituents of semen & aids in the storage and transport of spermatozoa

  • septa; lobules

    _______ form 200-300 compartments called _______.

  • sperm forming cells, sertoli, leydig

    What are the cells located in the Seminiferous Tubules? (3)

  • form blood-testis barrier, support developing sperm cells, produce fluid, control sperm release, secrete inhibin

    What are the functions of the Sertoli Cells? (5)

  • sertoli function, sperm number, spermatogenic status

    Inhibin B is positively correlated with? (3)

  • FSH

    Inhibin B is negatively correlated with _____.

  • fructose

    -provides energy for the sperm

  • prostaglandins

    -contributes to the mobility and viability of the sperm

  • fructose, prostaglandins, coagulating proteins

    The fluid from the seminal vescicles is viscous and contains: (3)

  • numerous short ducts; prostatic urethra

    ________ from the substances of the prostate gland empty in the ______.

  • bulbourethral

    -a short duct that enters the proximal end of the penile urethra.

  • b

    Secretes alkaline mucus-like fluid .

    a) prostate gland

    b) bulbourethral gland

  • a

    Secretes thin, milky colored alkaline fluid.

    a) prostate gland

    b) bulbourethral gland

  • a

    Secretions from this gland enhance the motility of sperm

    a) prostate gland

    b) bulbourethral gland

  • b

    Secretions of this gland neutralize acidity of vagina & provide lubrication during sex.

    a) prostate gland

    b) bulbourethral gland

  • fsh; sertoli

    For spermatogenesis to occur, ____ must bind to certain receptors on _______ cells.

  • in embryonic development primordial germ cells enter the testes and differente into spermatogonia where they remain dormant until puberty

    Explain Spermatogenesis before puberty.

  • hormones stimulate spermatogonia to divide by mitosis creating daughter cells that are called primary spermatocytes; each primary divides into two secondary spermatocytes with 23 chromosomes; after meiosis 2, each secondary spermatid produces 2 spermatids; 4 total

    Explain Spermatogeneis at puberty.

  • 46

    How many chromosomes are in a primary spermatocyte?

  • 23

    How many chromosomes are in a secondary spermatocyte?

  • f; some remain as spermatogonia

    All spermatogonia go on to become primary spermatocytes. T/F?

  • spermatogenesis, androgen-binding protein, plasminogen activator, inhibin

    FSH stimulates what? (4)

  • lutenizing; leydig

    _______ hormone stimulates the production of testosterone by acting on ______ cells.

  • a

    Which form of Hypogonadism is characterized by testicular failure?

    a) primary

    b) secondary

    c) tertiary

  • b

    Which form of Hypogonadism is caused by failure to stimulate the testes via gonadotropins?

    a) primary

    b) secondary

    c) tertiary

  • c

    Which form of Hypogonadism is caused by a lack of stimulus to secrete gonadotropins?

    a) primary

    b) secondary

    c) tertiary

  • afferent; pudendal; ascending; sacral

    ________ impulses from sensory receptors in the glans penis pass through the _______ nerve to _______ fibers in the spinal cord by way of the ______ plexus.

  • shunting; corpus cavernosum

    Erection involves the ______ of blood into the ______.

  • f; sympathetic

    Ejaculation is controlled by the parasympathetic nervous system. T/F?
