Q

cells of sertoli
(nurse cells)

A

contain glycogen for the nourishment of sperms

Q

nurse cells functions

A
  1. maintain blood-testis barrier
    blood-testis barrier
    isolates seminiferous
    tubules
  2. support mitosis and meiosis
    stimulated by: follicle
    stimulating hormone
    testosterone
  3. support of spermiogenesis
    surround and enfold
    supplements
  4. secrete inhibin
    depresses: pituitary
    production of FSH
    hypthalamic
    secrention of GnRH
    regulation of FSH and
    GnRH
  5. secretion of androgen-binding protein (ABP)
    binds androgens
    production of ABP
    is stimulated by FSH
  6. secretion of Mullerian-inhibiting factos (MIF)
    causes regression of
    fetal mullerian ducts
