10. What is the name of the
male's sex hormone?
__________________.
Explanation
Testosterone is the name of the male sex hormone. It is primarily produced in the testicles and is responsible for the development of male reproductive tissues and secondary sexual characteristics, such as muscle mass and facial hair. Testosterone plays a crucial role in regulating sex drive, sperm production, and overall male fertility. It also has an impact on mood, energy levels, and bone density.

3. The ________________ provides
the passageway for childbirth and menstrual flow.
Explanation
The vagina is a muscular canal that serves as the passageway for childbirth and the flow of menstrual blood. It connects the uterus to the external genitalia and is responsible for receiving the penis during sexual intercourse. The vagina also plays a crucial role in sexual pleasure and lubrication.

2. The _______________ is
suspended by broad ligaments and is located between the urinary bladder and the
rectum.
Explanation
The uterus is suspended by broad ligaments and is located between the urinary bladder and the rectum.

7. ___________________
works with estrogen to produce a normal menstrual cycle
Explanation
Progesterone works with estrogen to produce a normal menstrual cycle. This hormone is responsible for preparing the uterus for pregnancy by thickening the lining of the uterus. It also helps regulate the menstrual cycle by controlling the release of eggs from the ovaries and maintaining the uterine lining. Without adequate levels of progesterone, the menstrual cycle may become irregular or absent, and it may be difficult to conceive or maintain a pregnancy.

9. Days 6-14 of the hormonal
interaction of the female cycle is known as the
__________________ phase.
Explanation
Days 6-14 of the hormonal interaction of the female cycle is known as the proliferative phase. During this phase, the levels of estrogen increase, causing the endometrium to thicken and prepare for potential fertilization. The proliferative phase is characterized by the growth and development of the ovarian follicles, leading to the release of a mature egg during ovulation. This phase is crucial for fertility as it provides an optimal environment for the fertilized egg to implant in the uterus.

1. List the female's internal
reproductive organs.
________________________.
_______________________.
________________________. _______________________.
Explanation
The correct answer includes the internal reproductive organs of a female, which are the uterus, vagina, fallopian tubes, and ovaries. These organs are essential for reproduction and play a crucial role in the menstrual cycle, fertilization, and pregnancy. The uterus is where a fertilized egg implants and develops into a fetus. The vagina is the birth canal and also serves as the opening for menstrual flow. The fallopian tubes transport eggs from the ovaries to the uterus, and the ovaries produce eggs and hormones.
8.
14. The _______________ is
anterior to the head of the mature sperm.
Explanation
The acrosome is located anterior to the head of the mature sperm. The acrosome is a cap-like structure that covers the anterior portion of the sperm head. It contains enzymes that are essential for fertilization. These enzymes help the sperm penetrate the outer layers of the egg during fertilization. Therefore, the acrosome plays a crucial role in the process of fertilization by allowing the sperm to fuse with the egg and initiate the development of an embryo.

11. What male reproductive organ
is suspended in the scrotal sac outside of the abdominopelvic cavity?
__________________
Explanation
The testes are the male reproductive organs that are suspended in the scrotal sac outside of the abdominopelvic cavity. The scrotal sac provides a cooler environment for the testes, which is necessary for sperm production. This positioning also helps protect the testes from potential damage and allows for easier regulation of temperature.
10.
6. ______________ are for the
production of oogenesis and hormones.
Explanation
The ovaries are responsible for the production of oogenesis, which is the development of eggs, and hormones such as estrogen and progesterone. These hormones play a crucial role in the regulation of the female reproductive system, including the menstrual cycle and pregnancy. Therefore, the ovaries are essential for female fertility and the overall functioning of the reproductive system.
11.
5. Which of the female
reproductive organs has finger-like projections that partially surround each
ovary?
_______________________________________________.
Explanation
The fallopian tubes have finger-like projections called fimbriae that partially surround each ovary. These fimbriae help to capture the released egg from the ovary and guide it into the fallopian tube for fertilization.
12.
8. Vaginal introitus is known as
the _________________________.
Explanation
The correct answer is "vaginal entrance." The vaginal introitus refers to the opening of the vagina, which is also known as the vaginal entrance. This is where penetration occurs during sexual intercourse and where menstrual blood exits the body.
13.
12. The __________________ caps
the superior part of the testes and runs down its posterior side.
Explanation
The epididymis is a structure that covers the superior part of the testes and extends down its posterior side. It is responsible for storing and maturing sperm before they are released during ejaculation.
14.
15. The male's interstitial
cells are activated during puberty by two hormones,
__________ and ___________.
Explanation
During puberty, the male's interstitial cells are activated by two hormones, FSH (follicle-stimulating hormone) and LH (luteinizing hormone). FSH stimulates the production of sperm in the testes, while LH stimulates the production of testosterone by the interstitial cells. These hormones work together to initiate and regulate the development of secondary sexual characteristics in males during puberty.
15.
13. The male's accessory
glandular structure includes:
________________________.
_______________________.
________________________.
_______________________.
Explanation
The male's accessory glandular structure includes seminal vesicles, prostate gland, Cowper's gland, and penis. These structures play important roles in the reproductive system. The seminal vesicles produce and store seminal fluid, which nourishes and protects sperm. The prostate gland produces a milky fluid that helps in the movement of sperm. Cowper's gland produces a clear fluid that lubricates the urethra. The penis is the male reproductive organ responsible for sexual intercourse and the release of sperm.
