Section 14.1 Biology (30) Quiz

Most of the structures are located inside the body, for example uterus, ovaries, oviduct, and the fimbrae are all located inside the body.

At its base the uterus forms a narrow opening called the cervix.

Female gametes can also be referred to as eggs.

The endometrium is richly supplied with blood vessels to provide nutrients for the fetus.

The given statement is false. Primary sex characteristics of a female include the presence of ovaries, fallopian tubes, uterus, and vagina, which are internal reproductive organs. The external characteristics, such as rounded shoulders, wider hips, and a deeper voice, are considered secondary sex characteristics. These characteristics develop during puberty due to hormonal changes and are not directly related to the reproductive organs.

The ovum is approximately 0.1 mm in diameter which is over 20 times larger than the head of a sperm.

Sperm move out of the epididymis through the ductus deferens.

The uterus is normally about the size and shape of a pear but can expand to many times its size as the fetus develops.

The correct answer is ovaries. The female gonads are called ovaries. They are responsible for producing eggs, as well as the hormones estrogen and progesterone. The term "ovary" refers to a single female gonad, while "ovaries" is the plural form, referring to both gonads.

The two oviducts are commonly referred to as Fallopian tubes.

The term fimbrae comes from a Latin word that means "threads" or "fringes".

The gonads are testis (in males) and ovaries (in females).

The fertilized egg becomes a fetus after it has been implanted in the endometrium for approximately eight weeks.

The vulva includes the labia majora and labia minora.

Sertoli cells are located within the seminiferous tubules of the testes. These cells play a crucial role in spermatogenesis, the process of sperm development. They provide structural support, nourishment, and protection to the developing sperm cells, ensuring their proper maturation.  Sources and related content

The structures that are not directly related to reproductive function are called secondary sex characteristics. These are physical features that develop during puberty under the influence of sex hormones but are not directly involved in reproduction itself. Examples include breast development in females and facial hair growth in males.

If a living sperm encounters the egg in the oviduct, fertilization may take place.

In the follicles the above process is called ovulation.

The endometrium lines the uterus which can also be referred to as the "womb".

The egg is not motile, the have no structures to propel themselves, the beating cilia in the oviduct create a current that moves the ovum toward the uterus.

Sex hormones are produced by the gonads, for example testosterone is produced by the testes by the interstitial cells.

Sperm are transported from each testis to the epididymis, where they undergo maturation and become motile. The epididymis is a coiled tube located behind each testis, serving as a storage and maturation site for sperm. It provides an optimal environment for sperm to gain the ability to swim and fertilize an egg. This process takes place over several weeks as the sperm pass through the epididymis, acquiring the necessary motility and ability to survive in the female reproductive tract.

While Sertoli cells are crucial for sperm development, they do not secrete testosterone. This is the primary function of the Leydig cells, also known as interstitial cells, which are located in the connective tissue between the seminiferous tubules within the testes. The Sertoli cells are responsible for providing nutrients and protection to the developing sperm, forming the blood-testis barrier, and phagocytosing the residual cytoplasm shed by the sperm during maturation.
