_____________ _____________ is a congenital deformity in which there is an opening in the roof of the mouth.
Correct Answer
cleft palateExplanation
Cleft palate is a congenital deformity characterized by an opening in the roof of the mouth. This condition occurs during fetal development when the tissues that form the roof of the mouth do not fuse together properly. As a result, a gap or split is formed, causing communication between the oral and nasal cavities. Cleft palate can vary in severity, ranging from a small opening at the back of the mouth to a complete separation of the roof of the mouth. This condition can lead to difficulties with feeding, speech, and dental health if left untreated.Rate this question:

Excessive mechanical stress on bone is capable of causing a ______________.
Correct Answer
fracture
breakExplanation
Excessive mechanical stress on bone can lead to a fracture or break. When the bone is subjected to a force that exceeds its strength, it can cause the bone to crack or break. This can occur due to trauma, such as a fall or direct impact, or repetitive stress over time, such as in the case of overuse injuries. Fractures or breaks can vary in severity, ranging from hairline fractures to complete breaks where the bone is separated into two or more pieces.Rate this question:
- 18.
This type of bone fracture is a simple fracture with no open wound.
- A.
Closed Fracture
- B.
Comminuted Fracture
- C.
Spiral Fracture
- D.
Greenstick Fracture
Correct Answer
A. Closed FractureExplanation
A closed fracture refers to a type of bone fracture where the bone breaks but does not puncture the skin, resulting in no open wound. This means that the fractured bone remains within the body, causing pain and swelling, but without any external exposure. In contrast, other types of fractures like comminuted, spiral, or greenstick fractures may involve open wounds or more complex patterns of bone breakage. Therefore, the correct answer is closed fracture.Rate this question:

In this type of fracture, the bone has been twisted apart.
- A.
Impacted Fracture
- B.
Open Fracture
- C.
Closed Fracture
- D.
Spiral Fracture
Correct Answer
D. Spiral FractureExplanation
A spiral fracture occurs when a bone is twisted apart. This type of fracture is characterized by a spiral-shaped break in the bone, usually caused by a twisting force applied to the bone. It is commonly seen in sports-related injuries or accidents where a rotational force is applied to the bone. In a spiral fracture, the bone is twisted apart, resulting in a distinctive fracture pattern.Rate this question:

This fracture is when the broken ends of the bone are jammed into each other.
- A.
Comminuted Fracture
- B.
Impacted Fracture
- C.
Open Fracture
- D.
Spiral Fracture
Correct Answer
B. Impacted FractureExplanation
An impacted fracture occurs when the broken ends of the bone are jammed into each other. This can happen when a bone is subjected to a great amount of force or pressure, causing the fractured ends to become wedged or impacted together. This type of fracture typically results in a stable and immobile bone, as the impacted ends provide support and stability to the fracture site.Rate this question:

One side of the bone is broken and the other is bent with this type of fracture.
- A.
Greenstick Fracture
- B.
Closed Fracture
- C.
Spiral Fracture
- D.
Open Fracture
Correct Answer
A. Greenstick FractureExplanation
A greenstick fracture occurs when one side of a bone is broken and the other side is bent. This type of fracture is commonly seen in children, as their bones are more flexible and have a higher tendency to bend rather than break completely. The term "greenstick" refers to the analogy of a green tree branch that is bent but not completely snapped. Unlike a closed fracture where the broken bone does not penetrate the skin or an open fracture where the bone breaks and protrudes through the skin, a greenstick fracture is a closed fracture where the skin remains intact.Rate this question:
-

Name the type of bone fracture:There is more than one fracture line and the bone is splintered or crushed.
- A.
Open Fracture
- B.
Spiral Fracture
- C.
Greenstick Fracture
- D.
Comminuted Fracture
Correct Answer
D. Comminuted FractureExplanation
A comminuted fracture occurs when there is more than one fracture line and the bone is splintered or crushed. This type of fracture usually happens due to high impact injuries or significant trauma. The bone breaks into multiple fragments, making it difficult to align and stabilize for proper healing. Treatment for a comminuted fracture often involves surgery to remove any bone fragments and realign the bone with the help of plates, screws, or rods.Rate this question:
-
- 23.
Name the type of bone fracture described:A broken bone protrudes through the skin or an external wound leads to a broken bone.
- A.
Open Fracture
- B.
Impacted Fracture
- C.
Comminuted Fracture
- D.
Spiral Fracture
Correct Answer
A. Open FractureExplanation
An open fracture is a type of bone fracture where the broken bone protrudes through the skin or an external wound leads to a broken bone. In this type of fracture, the bone is exposed to the external environment, increasing the risk of infection and complicating the healing process. Prompt medical attention is necessary to clean the wound, stabilize the fracture, and prevent further complications.Rate this question:
