Question 1

Joints serve which of the following functions?&#10;A) Bear weight and provide stability&#10;B) Allow motion&#10;C) Contain fluid that lubricates and nourishes the cartilage&#10;D) All of the above

Accepted Answer

Joints serve multiple functions such as bearing weight and providing stability, allowing motion, and containing fluid that lubricates and nourishes the cartilage. Therefore, option D "All of the above" is the correct choice.

Question 2

What type of structure is located where tendons pass over a bone or joint and serves to decrease friction?&#10;A) Cartilage&#10;B) Fat pad&#10;C) Bursa&#10;D) Fibrocartilage

Accepted Answer

A structure that serves to decrease friction where tendons pass over a bone or joint is called a bursa. Bursae are fluid-filled sacs that are located near areas of friction, such as between tendons, ligaments, or bones. They serve to reduce friction and cushion the area. Other structures listed, such as cartilage, fat pad, and fibrocartilage, may also be located near tendons or joints, but they do not specifically serve to decrease friction.

Question 3

The two bones of a joint are held together and supported by which of the following structures?&#10;A) Tendon&#10;B) Bursa&#10;C) Ligament&#10;D) Fibrocartilage

Accepted Answer

Ligaments are dense connective tissue structures that connect bone to bone and provide stability to joints by holding the bones together. Tendons attach muscle to bone and transmit forces generated by the muscle to move the bone. Bursae are small fluid-filled sacs that reduce friction between different tissues, such as between a tendon and a bone. Fibrocartilage is a type of cartilage that provides cushioning and support to some joints, such as the knee joint. However, it does not directly hold the bones of a joint together. Therefore, the best choice is C) Ligament.

Question 4

Which of the following statements is true of a ligament?&#10;A) They provide support to a joint.&#10;B) They can serve as an attachment for cartilage.&#10;C) They can serve as an attachment for fascia.&#10;D) All of the above are true of a ligament.

Accepted Answer

Ligaments provide support to joints, can serve as attachments for cartilage, and can also serve as attachments for fascia, making all the provided statements true of ligaments.

Question 5

Hip medial rotation occurs in which plane and around which axis?&#10;A) Transverse plane through a vertical axis&#10;B) Sagittal plane through a frontal axis&#10;C) Frontal plane through a sagittal axis&#10;D) None of the above

Accepted Answer

Hip medial rotation occurs around a vertical axis in the transverse plane, as the femur rotates medially within the acetabulum. Choice B is incorrect because sagittal planes are perpendicular to frontal axes, so medial rotation cannot occur around a frontal axis in the sagittal plane. Choice C is incorrect because frontal planes are perpendicular to sagittal axes, so medial rotation cannot occur around a sagittal axis in the frontal plane. Choice D is incorrect because one of the other choices must be correct.

Question 6

Which of the following types of joints is NOT a fibrous joint?&#10;A) Gomphosis&#10;B) Synarthrosis&#10;C) Synovial joint&#10;D) Syndesmosis

Accepted Answer

Fibrous joints are classified as those where the bones are connected by collagen fibers, which makes them immovable or slightly movable. Gomphosis (teeth in sockets), synarthrosis (immoveable joints), and syndesmosis (joints connected by ligaments) are all examples of fibrous joints. Synovial joints are characterized by the presence of a joint cavity filled with synovial fluid, which allows for a wide range of movement, and are not fibrous joints.

Question 7

The wrist is an example of which type of joint?&#10;A) Nonaxial&#10;B) Uniaxial&#10;C) Biaxial&#10;D) Triaxial

Accepted Answer

The wrist joint is an example of a biaxial joint as it allows for movements in two planes: flexion/extension and abduction/adduction.

Question 8

A biaxial joint allows motion in how many directions?&#10;A) One&#10;B) Two&#10;C) Three&#10;D) None of the above

Accepted Answer

A biaxial joint allows motion in two directions, such as the wrist joint which allows motion in the sagittal and frontal planes. Therefore, the correct choice is B.

Question 9

A broad,flat tendinous sheet is called&#10;A) linea alba.&#10;B) aponeurosis.&#10;C) elastic cartilage.&#10;D) labrum.

Accepted Answer

A broad, flat tendinous sheet is called an aponeurosis. The linea alba is a specific aponeurosis that runs down the middle of the abdominal muscles. Elastic cartilage is a type of cartilage found in the ear and nose. The labrum is a ring of fibrocartilage found in the shoulder and hip joints.

Question 10

The hip is an example of which type of joint?&#10;A) Nonaxial&#10;B) Uniaxial&#10;C) Biaxial&#10;D) Triaxial

Accepted Answer

The hip joint is a triaxial joint, allowing movement in three planes: flexion/extension, abduction/adduction, and internal/external rotation.

Question 11

Forearm pronation occurs in which plane and around which axis?&#10;A) Transverse plane through a transverse axis&#10;B) Transverse plane through a vertical axis&#10;C) Sagittal plane through a frontal axis&#10;D) Frontal plane through a sagittal axis

Accepted Answer

The answer of Forearm pronation occurs in which plane and...

Question 12

Shoulder abduction occurs in which plane and around which axis?&#10;A) Frontal plane through a sagittal axis&#10;B) Frontal plane through a frontal axis&#10;C) Transverse plane through a vertical axis&#10;D) Sagittal plane through a frontal axis

Accepted Answer

The answer of Shoulder abduction occurs in which plane and...
