The sexual response cycle has four phases: excitement, plateau, orgasm, and resolution. Both men and women experience these phases, although the timing usually is different.
32. ANS: E. Only a & b.
Plateau phase in females:
The plateau stage in females is basically a continuation of the same changes evident in the excitement stage. The clitori.s becomes extremely sensitive and withdraws slightly and the bartholin glands produce further lubrication. The tissues of the outer third of the vagin.a swell, and the pubococcygeus muscle tightens, reducing the diameter of the opening of the vagin.a. Masters and Johnson refer to the changes that take place during the plateau stage as the orgasmic platform. For those who never achieve orgasm, this is the peak of sexual excitement.
33. ANS: E. 1, 2, 3, 4, 5, 6.
34. ANS: E. 1, 2, 3, 4, 5, 6.
A Sertoli cell is a "nurse"cell of the testicles that is part of a seminiferous tubule and helps in the process of spermatogenesis; that is, the production of sperm. The function of the supporting cells (Sertoli) is controlled by the FSH pituitary hormone. Sertoli cells synthetize 60 various proteins that are connected with reproduction. The most important are inhibin, androgen-binding-protein (ABP) and the antimüllerian hormone (AMH). Sertoli cells also act as phagocytes, consuming the residual cytoplasm during spermatogenesis.
35. ANS: D. all the above.
