How Much Do You Know About Embryology? Trivia Quiz
How much do you know about embryology? Do you suppose you know enough to pass this quiz? Embryology is the study of the formation and development of an embryo and fetus. It is the ball of splitting cells that results after fertilization is labeled an embryo for eight weeks and from nine weeks after conception. It is the term used as a “fetus. ” This quiz will determine whether or not you know about embryology.

Triploblastic
- A.
A condition of the blastula in which there are three primary germ layers: the ectoderm, mesoderm, and endoderm. The germ layers form during gastrulation of the blastula.
- B.
A technique that is used to show how a cell or tissue moves and what it will become during normal development. Was developed by Walter Vogt as a means by which to trace the development of specific regions of the early embryo.
- C.
Refers to the initiation or cause of a change or process, such as the production of a specific morphogenetic effect in the developing embryo.
- D.
(a kind of sustentacular cell) is a 'nurse' cell of the testes that is part of a seminiferous tubule. They nurture the developing sperm cells during spermatogenesis. It is activated by follicle-stimulating hormone and has FSH-receptor on its membranes
- E.
A 7 hr period after sperm is ejaculated into the vagina, a glycoprotein coat and seminal proteins are removed from the surface of the acrosome; this makes them more active; occurs in the uterus or uterine tubes by secreted substances by female genital track.
Correct Answer
A. A condition of the blastula in which there are three primary germ layers: the ectoderm, mesoderm, and endoderm. The germ layers form during gastrulation of the blastula.Explanation
Triploblastic refers to the condition of the blastula where there are three primary germ layers - the ectoderm, mesoderm, and endoderm. These germ layers are formed during gastrulation of the blastula. Gastrulation is a critical stage in embryonic development where the cells rearrange and differentiate to form the three germ layers, which eventually give rise to different tissues and organs in the body.Rate this question:

Refers to the initiation or cause of a change or process, such as the production of a specific morphogenetic effect in the developing embryo.
Correct Answer
B. A 7 hr period after sperm is ejaculated into the vagina, a glycoprotein coat and seminal proteins are removed from the surface of the acrosome; this makes them more active; occurs in the uterus or uterine tubes by secreted substances by female genital track.Explanation
Capacitation refers to the process in which the glycoprotein coat and seminal proteins are removed from the surface of the acrosome of sperm cells, making them more active. This process occurs approximately 7 hours after sperm is ejaculated into the vagina and takes place in the uterus or uterine tubes. It is facilitated by secreted substances from the female genital tract.Rate this question:

Correct Answer
A. Refers to the initiation or cause of a change or process, such as the production of a specific morphogenetic effect in the developing embryo.Explanation
Induction refers to the initiation or cause of a change or process, such as the production of a specific morphogenetic effect in the developing embryo. This means that induction is responsible for triggering a specific effect or change in the embryo's development. It is a crucial process in embryology and plays a significant role in shaping the structure and function of organisms during their early stages of growth.Rate this question:

Correct Answer
E. (a kind of sustentacular cell) is a 'nurse' cell of the testes that is part of a seminiferous tubule. They nurture the developing sperm cells during spermatogenesis. It is activated by follicle-stimulating hormone and has FSH-receptor on its membranesExplanation
Sertoli cells are sustentacular cells in the testes that provide support and nourishment to developing sperm cells during spermatogenesis. They are activated by follicle-stimulating hormone (FSH) and have FSH receptors on their membranes. This means that when FSH binds to these receptors, it triggers the activation of Sertoli cells, allowing them to nurture and support the developing sperm cells.Rate this question:

Correct Answer
C. A technique that is used to show how a cell or tissue moves and what it will become during normal development. Was developed by Walter Vogt as a means by which to trace the development of specific regions of the early embryo.Explanation
The correct answer refers to a technique called fate mapping, which was developed by Walter Vogt. This technique is used to track the movement and development of cells or tissues during normal embryonic development. It allows researchers to determine what specific regions of the early embryo will become in the fully developed organism. Fate mapping helps in understanding the process of morphogenesis and the initiation of different developmental changes in the embryo.Rate this question:

____________ is the basic unit of female reproductive biology and is composed of roughly spherical aggregations of cells found in the ovary. They contain a single oocyte. These structures are periodically initiated to grow and develop, culminating in ovulation of usually a single competent oocyte. These eggs/ova are only developed once every menstrual cycle.
Correct Answer
Follicle cellExplanation
Follicle cells are the basic unit of female reproductive biology and are composed of roughly spherical aggregations of cells found in the ovary. They contain a single oocyte. These structures are periodically initiated to grow and develop, culminating in ovulation of usually a single competent oocyte. These eggs/ova are only developed once every menstrual cycle. Therefore, follicle cells play a crucial role in the process of female reproduction.Rate this question:

In the uterus are the tube-like ____________, lined by ciliated columnar epithelium. They are of small size in the unimpregnated uterus, but shortly after impregnation become enlarged and elongated, presenting a contorted or waved appearance.
Correct Answer
Uterine glandsExplanation
The correct answer is "Uterine glands". In the uterus, there are tube-like structures called uterine glands. These glands are lined by ciliated columnar epithelium. They are normally small in size in the unimpregnated uterus. However, shortly after impregnation, they become enlarged and elongated, and they appear contorted or waved.Rate this question:

_______________ is any mesoderm in the uterus that is not involved with the embryo itself. Included are mesoderms in the amnion, chorion, yolk sac, and connecting stalk.
Correct Answer
Extraembryonic mesodermExplanation
The extraembryonic mesoderm refers to any mesoderm in the uterus that is not directly involved with the embryo itself. This includes the mesoderms in the amnion, chorion, yolk sac, and connecting stalk. These structures provide support and nourishment to the developing embryo, but are not part of the embryo itself.Rate this question:

_______________ is a rod-shaped cord of cells on the dorsal aspect of an embryo, defining the primitive axis of the body and serving as the center of development of the axial skeleton; it is the common factor of all chordates.
Correct Answer
NotochordExplanation
The notochord is a rod-shaped cord of cells on the dorsal aspect of an embryo. It defines the primitive axis of the body and serves as the center of development of the axial skeleton. The notochord is the common factor of all chordates, which are a group of animals that includes vertebrates.Rate this question:

______________ is the thickened plate of ectoderm in the embryo that develops into the neural tube.
Correct Answer
Neural plateExplanation
The neural plate is the thickened plate of ectoderm in the embryo that develops into the neural tube. This process is known as neurulation, and it is a critical step in the formation of the central nervous system. The neural plate eventually folds in on itself to form the neural tube, which gives rise to the brain and spinal cord. This transformation from neural plate to neural tube is essential for the proper development and functioning of the nervous system.Rate this question:
