Human Anatomy Prep Quiz
When you grow attached to something for your entire life, it can be very easy to take it for granted without learning about all of the work being done to keep it going – your body is the prime example of that. What functions, organs and other features of the human anatomy allow us to live our daily lives without a hitch? Take the following quiz to see if you know enough about your body!

Which process would be stopped if a poison interefred with ATP production?
- A.
Osmosis
- B.
Lysosomes
- C.
Anaphase
- D.
Active transport
- E.
All are correct
Correct Answer
D. Active transportExplanation
If a poison interferes with ATP production, it would affect the process of active transport. Active transport is an energy-dependent process that requires ATP to move substances across a cell membrane against their concentration gradient. Without ATP, active transport cannot occur, leading to disruption in the movement of ions and molecules across the membrane. Osmosis, lysosomes, and anaphase are not directly dependent on ATP production, so they would not be affected by the poison. Therefore, the correct answer is active transport.Rate this question:

In the plasma membrane of the cell, cholestorol acts to
- A.
Form receptor molecules
- B.
Increase the fluidity of the membrane
- C.
Make the membrane more resistant to freezing
- D.
Restrict the energy of most molecules
Correct Answer
B. Increase the fluidity of the membraneExplanation
Cholesterol acts to increase the fluidity of the plasma membrane. It does so by inserting itself between the phospholipid molecules in the membrane, preventing them from packing too closely together. This helps to maintain the proper balance of rigidity and flexibility in the membrane, allowing it to function properly.Rate this question:

Which organelle is most active aptosis(programmed cell death)? This organelle is also found in large amounts in white blood cells.
- A.
Nucleaus
- B.
Lysosomes
- C.
Aptopic
- D.
Mitochondria
- E.
Endoplasmic reticulum
Correct Answer
D. MitochondriaExplanation
Mitochondria is the correct answer because it is the organelle most active in apoptosis, which is programmed cell death. Additionally, mitochondria are found in large amounts in white blood cells.Rate this question:

In the cell life cycle, DNA is replicated during
- A.
G1
- B.
Anaphase
- C.
G2
- D.
S
Correct Answer
D. SExplanation
In the cell life cycle, DNA is replicated during the S phase. This phase occurs after the G1 phase and before the G2 phase. During the S phase, the cell's DNA is duplicated, resulting in two identical copies of each chromosome. This ensures that each daughter cell formed during cell division will receive a complete set of genetic material. The G1 and G2 phases are important for cell growth and preparation for cell division, but DNA replication specifically occurs during the S phase.Rate this question:

Which kind of tissue would you expect to find in an area of the body that experiences friction and wear and tear
- A.
Simple couboidal tissue
- B.
Simple columnar epithelial tissue
- C.
Stratified squamous epithelial tissue
- D.
Pseudostratified ciliated columanar epithelial tissue
Correct Answer
C. Stratified squamous epithelial tissueExplanation
Stratified squamous epithelial tissue is the correct answer because it is designed to withstand friction and wear and tear. This type of tissue consists of multiple layers of flat cells that provide protection to underlying tissues. It is commonly found in areas of the body that experience constant abrasion, such as the skin, mouth, and esophagus. The stratified nature of this tissue allows for durability and regeneration, making it well-suited for areas that are subjected to mechanical stress.Rate this question:

Which of the following is not part of the preembryonic stage of development?
- A.
Cleavage
- B.
Formation of the three primary germ layers
- C.
Implantation
- D.
Appearance of organs and organ systems
Correct Answer
D. Appearance of organs and organ systemsExplanation
The preembryonic stage of development refers to the initial stages of embryonic development, before the formation of organs and organ systems. During this stage, the zygote undergoes cleavage, where it divides into multiple cells. It also goes through the process of implantation, where it attaches to the uterine wall. Additionally, the formation of the three primary germ layers, which give rise to different tissues and organs, occurs during this stage. Therefore, the appearance of organs and organ systems is not part of the preembryonic stage of development.Rate this question:

The release of an egg from the ovary is called
- A.
Thelarchle
- B.
Muscular tissue
- C.
Ovulation
- D.
Puperty
Correct Answer
C. OvulationExplanation
Ovulation is the correct answer because it refers to the release of an egg from the ovary. During ovulation, a mature egg is released from the ovary and travels down the fallopian tube, where it may be fertilized by sperm. This process is a crucial part of the menstrual cycle and is necessary for reproduction. The other options, thelarchle, muscular tissue, and puberty, do not accurately describe the release of an egg from the ovary.Rate this question:

What structure caps the head of a mature sperm and enables the sperm to penetrate an egg?
- A.
Mitochondria
- B.
Acrosome
- C.
Flagellum
- D.
Nucleaus
Correct Answer
B. AcrosomeExplanation
The acrosome is a structure that caps the head of a mature sperm. It contains enzymes that help the sperm penetrate the protective layers of the egg during fertilization. The mitochondria, flagellum, and nucleus are also important structures in a sperm, but they do not directly enable the sperm to penetrate an egg.Rate this question:

Where in the female's reproductive tract does fertalization usually occur?
- A.
The utuerus
- B.
The vagina
- C.
The ovary
- D.
The cervix
Correct Answer
C. The ovaryExplanation
Fertilization usually occurs in the fallopian tubes, not in the ovary itself. After ovulation, the egg is released from the ovary and travels through the fallopian tubes towards the uterus. If sperm is present in the fallopian tubes, fertilization can occur there. The fertilized egg then implants itself in the uterus for further development.Rate this question:

Which of the following lists the stages of prenatal development in the correct order?
- A.
Zygote, embryo, morula, cleavage, trophoblasts, fetus
- B.
Zygote, cleavage, morula, trophoblasts, embryo, fetus
- C.
Zygote, morula, clevage. trophoblasts, fetus, embryo
Correct Answer
B. Zygote, cleavage, morula, tropHoblasts, embryo, fetusExplanation
The correct answer is zygote, cleavage, morula, trophoblasts, embryo, fetus. This is the correct order of prenatal development stages. The zygote is formed when the sperm fertilizes the egg. Cleavage is the rapid division of the zygote into smaller cells. The morula is a solid ball of cells formed after several rounds of cleavage. Trophoblasts are cells that form the outer layer of the morula and eventually develop into the placenta. The embryo is formed when the inner cells of the morula differentiate into different cell types. Finally, the fetus is the stage of development after the embryo, where the organs and systems continue to grow and mature.Rate this question:
