Example Questions

Example Question #3 : Joints

Order the three main types of joints in descending order of mobility.

Possible Answers:

Amphiarthroses, synarthroses, diarthroses

Synarthroses, diarthroses, amphiarthroses

Diarthroses, amphiarthroses, synarthroses

None of these

Diarthroses, synarthroses, amphiarthroses

Correct answer:

Diarthroses, amphiarthroses, synarthroses

Explanation:

Diarthroses like the elbow and knee allow free movement. Amphiarthroses allow slight movement and are found in areas where flexibility is needed, but a lot of flexibility would be unwanted such as the vertebral joints. Synarthroses allow no movement. The sutures of the skull are an example.

Example Question #11 : Joints

The shoulder and the hip are considered what type of synovial joint?

Possible Answers:

Hinge joint

Ball-and-socket joint

Gliding joint

None of these

Pivot joint

Correct answer:

Ball-and-socket joint

Explanation:

The shoulder and the hip form the only ball-and-socket joints in the entire human body. Ball-and-socket joints give rise to multidirectional movement of all types except for gliding. Hinge joints, such as the elbow and knee, can only move in one plane. Pivot joints, such as the radioulnar joints allow rotation. Plane/gliding joints only allow gliding movements.

Example Question #12 : Joints

What type of structural joint contains a cavity filled with fluid?

Possible Answers:

Fibrous joint

All of these

None of these

Synovial joint

Cartilaginous joint

Correct answer:

Synovial joint

Explanation:

Synovial joints contain a synovial cavity that contains synovial fluid. This joint structure allows for many different types of movement. Neither cartilaginous nor fibrous joints contain fluid-filled cavities. 

Example Question #13 : Joints

Which of the following joints is not a diarthrosis?

Possible Answers:

Humero-ulnar joint

Distal tibofibular joint

Tibiofemoral joint

Glenohumeral joint

Correct answer:

Distal tibofibular joint

Explanation:

A diarthrosis is another name for a synovial joint. Synovial joints (diarthroses) allow more movment than synarthroses. The tibiofemoal joint (the knee), the humero-ulnar joint (one of the elbow joints), and the glenohumeral joint ("the shoulder") are all synovial joints. Although the proximal tibiofibular joint is a diarthrosis, the distal tibiofibular joint is not; it is a type of synarthrosis.

Example Question #14 : Joints

Which of the following joints does not have an intra-articular discs\?

Possible Answers:

Sternoclavicular (SC) joint

Acromioclavicular (AC) joint

Coxafemoral joint

Temperomandibular joint (TMJ)

Correct answer:

Coxafemoral joint

Explanation:

Intra-articular discs are structures made of fibrocartilage that increase joint congruency, and improve shock absorption. They can be found in the AC joint, the SC joint, the TMJ, and several other joints. Similarly, the acetabular labrum in the coxafemoral joint is comprised of fibrocartilage, and improves joint congruency. However, it is not an intra-articular disc.

Example Question #15 : Joints

Which type of joint contains a joint cavity?

Possible Answers:

Cartilaginous joint

Synovial joint

Synarthrotic joint

Fibrous joint

Correct answer:

Synovial joint

Explanation:

Fibrous joints, also known as synarthroses, are joined by fibrous tissue, have no joint cavity, and allow little movement. An example of this is a suture, which is found between the flat bones of the skull.  Cartilaginous joints are joined by cartilage, have no joint cavity, and allow little or no movement. An example of this is the epiphyseal plate. Synovial joints, in contrast, do contain a joint cavity and allow a great deal of free movement. An example of this is the hip joint.

Example Question #16 : Joints

The knee is what type of joint?

Possible Answers:

Ball in socket joint

Hinge joint

Plateau joint

Saddle joint

None of these

Correct answer:

Hinge joint

Explanation:

The knee is composed of the femur and the tibia, which creates a hinge joint. The ball in socket would be the shoulder or hip, composed of a ball like structure that rotates around a socket like bone. The saddle joint is a special joint located in the thumb and allows for multiple motions. A plateau joint does not exist in the body.

Example Question #17 : Joints

Which are the only two saddle joints of the body?

Possible Answers:

Carpometacarpal and sternoclavicular

Radioulnar and tibiofibular

None of these

Acromioclavicular and interphalangeal 

Sternoclavicular and trapeziometacarpal

Correct answer:

Sternoclavicular and trapeziometacarpal

Explanation:

The sternoclavicular and trapeziometacarpal (thumb) joints are unique in that the involved bones have both convex and concave portions that give their saddle shape.

Example Question #18 : Joints

The intercarpal joints are an example of __________ joints.

Possible Answers:

pivot

condylar

ball and socket

saddle

gliding

Correct answer:

gliding

Explanation:

Gliding joints, also called plane joints, have flat articular surfaces that allow movement in all different directions. (There are eight carpal bones in the wrist: scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, hamate.)

Example Question #19 : Joints

Which type of joint permits the movements of flexion, extension, adduction, abduction, and rotation?

Possible Answers:

Pivot

Gliding

Hinge

Ellipsoid

Ball and socket

Correct answer:

Ball and socket

Explanation:

Ball and socket joints, such as the glenohumeral joint in the shoulder and acetabulofemoral joint in the hip, allow for the widest range of movement.
