E) a graafian follicle 10)

Answer 1

6.C. The sperm pathway from seminiferous tubule to the urethra: from the seminiferous tubule, sperm enters into the straight tubule, then from the straight tubule to rete testis, then from the rete testis to efferent ducts, then from efferent ducts to the ductus epididymis, then from the ductus epididymis to vas deferens. Then to the ampulla, ejaculatory duct and finally to the urethra.

7.D. Once GnRH is released from the hypothalamus and enters the hypothalamohypophysial portal system, FSH and LH secretion will occur.

8.B. The ovaries and uterus are held in position within the pelvis by bands of tissue called ligaments.  

9.B. Of the two million primary oocytes in the ovaries at birth, only about 400 are ovulated.

10.A. A primary oocyte with a single layer of granulosa cells is most appropriately called a primordial follicle.
