1.
Bone fragments into three or more pieces; common in the elderly
Correct Answer
C. Comminuted
Explanation
Comminuted fractures occur when a bone breaks into three or more pieces. This type of fracture is common in the elderly, as their bones tend to be more brittle and prone to breaking. In a comminuted fracture, the bone fragments are usually displaced and may require surgery to realign and stabilize the bone. This type of fracture can take longer to heal and may have a higher risk of complications compared to other types of fractures.
2.
Incomplete fracture where one side of the bone breaks and the other side bends; occurs only in children
Correct Answer
D. Greenstick
Explanation
A greenstick fracture is a type of incomplete fracture that occurs in children. In this type of fracture, one side of the bone breaks while the other side bends. It is called "greenstick" because it is similar to what happens when a green stick is bent - it may break on one side but not completely on the other side. This type of fracture is common in children because their bones are more flexible and less brittle than adult bones.
3.
One end of the fractured bone is force-fully driven in to the interior of the other.
Correct Answer
B. Impacted fracture
Explanation
The type of fracture described, where one end of the fractured bone is forcefully driven into the interior of the other, is commonly referred to as an "impacted fracture." In an impacted fracture, the ends of the broken bone are jammed together due to a compressive force, causing one fragment to be wedged into the other. Impacted fractures often occur in long bones, such as the femur or tibia, and can result from significant trauma or injury. They are typically stable fractures, and treatment may involve realigning and immobilizing the bone for proper healing.
4.
Fracture of the distal end of fibula
Correct Answer
D. Pott's fracture
Explanation
Pott's fracture refers to a fracture of the distal end of the fibula, along with a dislocation of the ankle joint. This type of fracture typically occurs as a result of an external rotation force applied to the foot, causing the fibula to break and the ankle to dislocate. The term "Pott's fracture" is named after Sir Percivall Pott, an 18th-century surgeon who first described this specific type of fracture.
5.
Fracture of the distal end of radius
Correct Answer
A. Colles' fracture
Explanation
Colles' fracture is a specific type of fracture that occurs at the distal end of the radius bone in the forearm. It is characterized by the displacement of the fractured bone fragment in a backward and outward direction, resulting in a characteristic deformity of the wrist. This fracture is commonly caused by a fall onto an outstretched hand, with the impact being transmitted to the radius bone. The name "Colles' fracture" is derived from the Irish surgeon Abraham Colles, who first described this type of fracture in the early 19th century.
6.
The study of bones is called?
Correct Answer
A. Osteology
Explanation
Osteology is the study of bones. It involves examining the structure, development, and function of bones, as well as the diseases and conditions that affect them. This field of study is important in various disciplines, including anthropology, archaeology, and medicine. By studying bones, researchers can gain insights into human evolution, identify ancient human remains, and diagnose and treat bone-related disorders and injuries. Myology is the study of muscles, mycology is the study of fungi, and cardiology is the study of the heart.
7.
What is the largest bone in the human body?
Correct Answer
A. Femur
Explanation
The femur is the largest bone in the human body. It is located in the thigh and is responsible for supporting the weight of the body and facilitating movement. The femur is a long, strong bone that connects the hip joint to the knee joint. It is essential for activities such as walking, running, and jumping. The patella, also known as the kneecap, is a smaller bone that protects the knee joint. The stapes is one of the three small bones in the middle ear. Therefore, the correct answer is femur.
8.
The knee cap bone is called?
Correct Answer
B. Patella
Explanation
The knee cap bone is called the patella. It is a small, triangular bone located in front of the knee joint. The patella acts as a protective shield for the knee joint and helps to increase the leverage of the thigh muscles. It also assists in the smooth movement of the knee joint during activities such as walking, running, and jumping. The fibula, femur, and tarsal are all other bones in the human body, but they are not specifically referred to as the knee cap bone.
9.
What is the smallest bone in the human body?
Correct Answer
A. Stapes
Explanation
The stapes is the smallest bone in the human body. It is one of the three bones in the middle ear and is commonly referred to as the stirrup bone. Its small size and shape allow it to transmit sound vibrations from the eardrum to the inner ear, contributing to our sense of hearing. The femur is the longest bone in the body, the carpal bones are found in the wrist, and the phalanges are the bones in the fingers and toes.
10.
Two bones are joined together by?
Correct Answer
A. Ligament
Explanation
Ligaments are the correct answer because they are tough, fibrous connective tissues that connect bones to other bones, providing stability and support to joints. Muscles are responsible for movement and are not directly involved in joining bones together. Tendons, on the other hand, connect muscles to bones, not bones to bones. Therefore, the correct answer is ligament.
