Study Notes

Mitosis and Meiosis

Chromatids separate, and each is now called a chromosome.
New nuclei form around the chromosomes, and the cells divide to form four daughter cells with half as many chromosomes as the parent cell.

Male Reproductive System

The dartos and cremaster muscles help regulate testes temperature.
The response of the dartos and cremaster is important in regulating the temperature in testes.
Testes or male gonads are oval organs within the scrotum.
Key functions of testes: produce sperm and produce male sex hormones.
The testes are divided into lobules.
Epididymis is a tightly coiled series of threadlike tubules that form a comma-shaped structure on the posterior side of the testes.

Penis

The attached portion of the penis to the body is known as the root.
The freer moving part is called the shaft or the body.
The penis is usually flaccid and hangs down, but during sexual excitation, it becomes erect, swollen, and gorged with blood.

Uterus

The uterine wall is composed of perimetrium (serous), myometrium (muscular), and endometrium (functional).
The perimetrium is a serous membrane that envelops the uterus and provides support to the uterus.
The myometrium is composed of smooth muscle and allows the uterus to stretch during pregnancy and childbirth.

Fallopian Tubes

The fallopian tubes are a passageway for the excretion of urine as well as the ejaculation of semen.
Fertilization of the ovum by the sperm usually occurs in the fallopian tube.

Ovaries

The term adnexa is used collectively when discussing the fallopian tubes, ovaries, and supporting tissues.
The ovaries are oval organs located within the pelvis.

Female Reproductive System

The vulva is the external female sex organ that receives the penis during sexual intercourse.
The vagina is a tubular fibromuscular structure approximately 8-10 cm in length that extends from the uterus to the exterior.
The vagina is also an organ of sexual response and allows passage of menstrual flow and birth of a baby.
The labia majora are larger, outer folds of skin equivalent to the male scrotum.
The labia minora are thin, inner folds of skin located between the clitoris and the base of the vagina.
The clitoris is a small erectile structure located in the vestibule, equivalent to the male penis.

Mammary Glands

Structurally related to the skin, but functionally related to the reproductive system because they produce milk for nourishment.
Enclosed within the breasts, situated anterior to the pectoralis, the major muscles of the chest.
Each adult female breast contains mammary glands, consisting of usually 15 to 20 granular lobes that are surrounded by adipose tissue.
