female genitals

Question 1

What is the widest and longest portion of the uterine tube where fertilization commonly occurs?

Answer 1

Ampulla of Uterine Tube

Fertilization typically occurs in this region.

Question 2

What is the funnel-shaped, open-ended portion of the uterine tube that captures the ovulated oocyte?

Answer 2

Infundibulum of Uterine Tube

This structure is located near the ovary.

Question 3

What are the finger-like projections at the infundibulum that help guide the oocyte into the uterine tube called?

Answer 3

Fimbriae of Uterine Tube

These projections play a crucial role in oocyte capture.

Question 4

What is the narrowest portion of the uterine tube that connects the ampulla to the uterine cavity?

Answer 4

Isthmus of Uterine Tube

It is the section closest to the uterus.

Question 5

What is the hollow space inside the uterus where implantation of the fertilized egg occurs?

Answer 5

Uterine Cavity

This area is essential for fetal development.

Question 6

What is the innermost layer of the uterus that undergoes cyclic changes during the menstrual cycle?

Answer 6

Endometrium

This layer supports implantation.

Question 7

What is the thick, muscular middle layer of the uterus responsible for contractions during labor?

Answer 7

Myometrium

It also plays a role during menstruation.

Question 8

What is the outermost serous layer of the uterus that provides structural support?

Answer 8

Perimetrium

This layer reduces friction with surrounding organs.

Question 9

What is the opening between the uterine cavity and the cervical canal called?

Answer 9

Internal Os

It regulates passage between the uterus and cervix.

Question 10

What is the lower, cylindrical portion of the uterus that connects to the vagina?

Answer 10

Cervix of Uterus

It secretes mucus to facilitate or block sperm entry.

Question 11

What is the passage within the cervix through which sperm travels to reach the uterus?

Answer 11

Cervical Canal

Menstrual blood and childbirth also occur through this canal.

Question 12

What is the opening of the cervix into the vagina called?

Answer 12

External Os

It controls the flow of materials in and out of the uterus.

Question 13

What is the narrow region of the uterus connecting the body of the uterus to the cervix?

Answer 13

Isthmus of Uterus

This region plays a role in labor contractions.

Question 14

What is the main central portion of the uterus where implantation and fetal development occur?

Answer 14

Body of the Uterus

This area is crucial for pregnancy.

Question 15

What is the dome-shaped, uppermost part of the uterus that serves as an important landmark in pregnancy?

Answer 15

Fundus of Uterus

It is involved in uterine contractions.

Question 16

What are the parts of the ovaries?

Answer 16

Ovarian cortex, ovarian medulla, ovarian follicles, corpus luteum

Each part has specific functions in reproduction.

Question 17

What are the functions of the ovaries?

Answer 17

• Produce and release oocytes through ovulation
• Secrete hormones such as estrogen, progesterone, inhibin, and relaxin

These hormones regulate the menstrual cycle and secondary sexual characteristics.

Question 18

What are the parts of the uterine (fallopian) tubes?

Answer 18

Infundibulum, fimbriae, ampulla, isthmus

Each part plays a role in the transport of the oocyte.

Question 19

What are the functions of the uterine (fallopian) tubes?

Answer 19

• Capture the ovulated oocyte and transport it toward the uterus
• Provide the site for fertilization
• Use cilia and peristaltic contractions to move the oocyte or fertilized egg

Fertilization typically occurs in the ampulla.

Question 20

What are the parts of the uterus?

Answer 20

Fundus, body, isthmus, cervix (includes internal os, cervical canal, external os)

Each part has distinct roles in reproduction.

Question 21

What are the functions of the uterus?

Answer 21

• Site for implantation of the fertilized egg and fetal development
• Provides structural support during pregnancy
• Contracts to expel the fetus during labor
• The endometrium undergoes cyclic changes to prepare for pregnancy

If fertilization does not occur, the endometrium is shed during menstruation.

Question 22

What are the parts of the cervix?

Answer 22

Internal os, cervical canal, external os

Each part contributes to the cervix’s functions.

Question 23

What are the functions of the cervix?

Answer 23

• Produces cervical mucus
• Acts as a protective barrier against infections
• Dilates during labor

The consistency of cervical mucus changes to facilitate or prevent sperm entry.

Question 24

What are the parts of the vagina?

Answer 24

Vaginal canal, vaginal orifice, hymen

Each part plays a role in the reproductive system.

Question 25

What are the functions of the vagina?

Answer 25

* Passageway for menstrual flow, intercourse, and childbirth * Contains an acidic environment that protects against infections * Expands to accommodate childbirth ## Footnote This structure is crucial for female reproductive health.

Question 26

What are the parts of the external genitalia (vulva)?

Answer 26

Mons pubis, labia majora, labia minora, clitoris, vestibule, vaginal orifice, urethral orifice, greater vestibular glands ## Footnote Each part has specific functions related to protection and stimulation.

Question 27

What are the functions of the external genitalia (vulva)?

Answer 27

* Protects the internal reproductive organs * Plays a role in sexual stimulation and arousal * Lubricates the vaginal opening ## Footnote The clitoris is particularly important for sexual arousal.

Question 28

What are the parts of the mammary glands?

Answer 28

Lobes, lobules, alveoli, lactiferous ducts, nipple, areola ## Footnote These structures are essential for lactation.

Question 29

What are the functions of the mammary glands?

Answer 29

* Produce and secrete milk for infant nourishment * Respond to hormonal regulation ## Footnote Hormones involved include prolactin and oxytocin.
