Chapter 25

Erection is caused by

erectile bodies filling with blood

The opening of the oviduct is surrounded by these structures.

fimbriae

Type of cell in the testes that produces testosterone.

interstitial

Mesometrium :

region of the broad ligament proximal to the uterus; encompasses greatest surface area

Fundus :

rounded region of the uterus, superior to the entry of the uterine tubes

The epithelium lining the vagina is

stratified squamous.

The deep inguinal ring is an opening in the fascia deep to which abdominal muscle?

transversus abdominis

Stratum functionalis :

undergoes cyclical changes in response to varying levels of hormones in the blood; shed during menstruation

The most common site of ectopic pregnancy is the

uterine tube

Fertilization of the ovum normally occurs in this region of the oviduct.

ampulla

Round ligaments :

anchor the uterus to the anterior body wall

The seminal vesicles

are glands that secrete most of the volume of the semen.

The largest macroscopic region of the uterus is its

body

Fingerlike placental structures where oxygen and nutrients from the maternal blood supply diffuse into the embryonic blood.

chorionic villi

Cervical canal :

contains glands that secrete mucus, which can block bacteria from vagina or block entry of sperm

Endometrium :

contains uterine glands that change in length as the endometrium thins and thickens

Involuntary contraction of this smooth muscle layer wrinkles and thickens the walls of the scrotum to prevent heat loss.

dartos muscle

The secretion of the seminal vesicles makes up about __________% of the volume of semen, and the secretion contains __________.

60 / fructose, prostaglandins, substances that enhance sperm motility

The central tendon or perineal body of the female perineum is the insertion point of most muscles that support the pelvic floor. During childbirth, this structure is sometimes torn by the infant's head. Which of the following statements is correct?

Damage to the central tendon can result in wreaking of the pelvic floor muscles, allowing the pelvic organs to sink inferiorly and the uterus to prolapse.

Which of the following statements regarding endometriosis is correct?

Endometrial cysts in the pelvic cavity lead to severe pain during menstruation.

John Frances works for the Acme Moving company. Recently he complained of a sharp pain in groin region especially when lifting heavy objects. What clinical condition does he have?

He has an inguinal hernia; there is a weakening in the abdominal wall and abdominal contents such as coils of intestine protrude into the inguinal canal.

What is benign prostatic hyperplasia?

It can lead to urinary retention, continual dribbling of urine, and urinary tract infections.

Which of the following statements about pelvic inflammatory disease is incorrect?

It inhibits ovulation.

Which of the following statements about pelvic inflammatory disease is correct?

Symptoms include tenderness of the lower abdomen, fever and vaginal discharge. A single episode of this condition can result in infertility due to scarring of the uterine tubes. It involves spread of infection, such as chlamydia or gonorrhea, that originates in the vagina and spreads to the uterus, uterine tubes, ovaries and eventually to the pelvic peritoneum.

Which of these statements concerning the cervix is FALSE?

The cervical mucus is the thickest at the midpoint of the menstrual cycle (Day 14).

During menstruation, fragments of endometrium can reflux into the uterine tubes and eventually end up in the pelvic cavity. How do the endometrial cells move from the uterine tubes into the pelvic cavity?

The endometrial cells enter the pelvic cavity because the uterine tubes open into the pelvic cavity near the ovary.

How is an ovulated oocyte directed into the uterine tube?

The infundibulum covers the ovary and the fimbriae cilia, generate currents in the pelvic cavity fluid that move the oocyte into the uterine tube.

In an adult woman who has never been pregnant, the breasts have poorly developed or no

lobules of acini/alveoli.

All of the following are located within the spermatic cord except the

superficial inguinal ring.
