Question 1

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

Shoulder abduction occurs in the frontal plane and moves through a sagittal axis. This is because in anatomical terms, movements in the frontal plane (dividing the body into front and back) occur around a sagittal axis (running from front to back).

Question 2

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 in the midline of the abdomen. Elastic cartilage is a type of cartilage found in the ear and nose, and the labrum is a piece of cartilage in the shoulder joint.

Question 3

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 4

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 because it can move in two directions: flexion-extension and abduction-adduction. It does not allow for rotation, which would be required for it to be a triaxial joint. It also does not operate in a single plane, which would make it a uniaxial joint.

Question 5

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 movement in both flexion/extension and abduction/adduction.

Question 6

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 all three functions listed: bearing weight and providing stability, allowing motion, and containing fluid that lubricates and nourishes the cartilage.

Question 7

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.

Question 8

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 ball-and-socket joint, which is a type of triaxial joint allowing for movement in multiple planes of motion.

Question 9

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 joints where two bones are held together by dense connective tissue, such as collagen. Gomphosis, synarthrosis, and syndesmosis are all examples of fibrous joints. Synovial joints, on the other hand, are joints where the bones are separated by a cavity filled with synovial fluid and surrounded by a capsule. Therefore, choice C, synovial joint, is not a fibrous joint.

Question 10

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 bursa is a fluid-filled sac that acts as a cushion between tendons, ligaments or muscles and the bone, reducing friction and allowing smooth movement.

Question 11

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

The answer of The two bones of a joint are...

Question 12

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...
