SOSCI 3: MODULE 1

Testes

the gonads or reproductive glands of the male body, analogous to the female ovaries

Seminiferous tubules (parts of testes)

manufacture sperm cells (spermatogenesis)

Interstitial cells (parts of the testes)

produce sex hormones (testosterone)

Epididymis

Sperm are stored here in which they mature for as long as six weeks

Vas deferens

Upon ejaculation, the sperm pass from the epididymis into the vas deferens. The vas passes up and out of the scrotum and toward the prostate.

Seminal vesicles

are two saclike structures that lie above the prostate, behind the bladder, and in front of the rectum. They produce about 60 percent of the seminal fluid, or ejaculate

Prostate

The prostate secretes a milky alkaline fluid that is part of the ejaculate.

Glans

Tip of the penis

Urethral opening

The opening through which urine and semen pass

Corona

The raised ridge at the edge of the glans.

Corpora Cavernosa

The two spongy bodies lying on top of the penis

Corpus Spongiosum

The single spongy body lying on the bottom of the penis.

Ovaries

The ovaries are two organs about the size and shape of unshelled almonds; they lie on either side of the uterus.

2 functions of the ovaries

1. produce eggs (ova)

2. Manufacture sex hormones estrogen and progesterone

Fallopian tubes

• also called oviducts (“egg ducts”)

• narrow and lined with cilia

• pathway by which the egg travels toward the uterus and the sperm reach the egg.

Infundibulum

• Fertilization of the egg

• the section of the tube closest to the ovary; the fertilized egg then

  travels the rest of the way through the tube to the uterus.

Uterus (3 parts)

1. Fundus (top)

2. Main body

3. Cervix (bottom)

Uterus (3 layers)

1. Endometrium — contains glands and blood vessels

2. Myometrium — contains primarily of muscles

3. Perimetrium — outer cover

Vagina (“birth canal”)

The vagina is the tube-shaped organ into which the penis is inserted during coitus; it also receives the ejaculate.

Mons pubis

The mons pubis is the rounded, fatty pad of tissue, covered with pubic hair, at the front of the body. It is also called the mons or the mons veneris, for “mountain of Venus”.

parts of the Clitoris

1. Tip

2. Shaft

3. Two crura

Tip (glans)

a knob of tissue situated externally in front of the vaginal opening and the urethral opening;

Shaft (Clitoris)

consisting of two corpora cavernosa (spongy bodies similar to those in the male’s penis) that extends perhaps an inch into the body

Two crura (clitoris)

longer spongy bodies that lie deep in the body and run from the tip of the clitoris to either side of the vagina, under the major lips

Labia majora

The outer lips are rounded pads of fatty tissue lying along both sides of the vaginal opening; they are covered with pubic hair.

Labia minora

The inner lips are two hairless folds of skin lying between the outer lips and running right along the edge of the vaginal opening.

Mammary glands

Glands responsible for milk production and neonatal growth, each with a separate opening to the nipple, and of fatty and fibrous tissues that surround the clusters of these glands.

Lactiferous (Milk) Ducts

Assists in lactation by transporting milk from mammary glands to the nipple.

What do you collectively call the external female sexual organs?

Vulva

Skene’s gland

The Skene’s gland, or female prostate (also called the paraurethral gland), lies between the wall of the urethra and the wall of the vagina
