What are male and female gonads? What do they produce?

Male gonads are the testes, which produce sperm and testosterone. Female gonads are the ovaries, which produce oocytes (eggs), estrogen, and progesterone.

Give an example of an accessory reproductive organ in men and women

Men: Prostate gland (or seminal vesicles, bulbourethral glands). Women: Uterus (or uterine tubes, vagina).

What hormones stimulate sexual maturity?

GnRH starts the signal from the hypothalamus. The anterior pituitary releases FSH and LH, which act on the gonads.

Explain autosomes vs sex chromosomes

Autosomes are the 22 pairs involved in many body traits and functions. Sex chromosomes are the remaining pair, typically XX or XY.

Give an overview of meiosis. What is produced at the end of each phase?

Meiosis I separates matching chromosome pairs, creating 2 cells. Meiosis II separates sister chromatids, resulting in 4 haploid cells in the standard process.

Be able to trace sperm cell lineage as they mature

Spermatogonia → primary spermatocytes → secondary spermatocytes → spermatids → spermatozoa.

What muscles aid in temperature regulation of the scrotum?

Dartos muscle and cremaster muscle.

Spermatozoa are found mainly where?

In the epididymis (where they are stored and complete maturation) and the seminiferous tubules of the testes.

The Vas deferens and seminal vesicles lead into the

Ejaculatory duct

Pre-ejaculate comes from which accessory gland?

Bulbourethral glands
