Question 3

Lifting up a glass to take a drink involves the elbow joint.Which of the following correctly characterizes that joint?
A) cartilaginous
B) pivot
C) diarthrotic
D) biaxial

Accepted Answer

The elbow joint is a diarthrotic joint, also known as a synovial joint. This means it is a freely moving joint that is surrounded by a joint capsule containing synovial fluid. The elbow joint allows for flexion and extension, as well as some rotation. It is not cartilaginous, as this type of joint is made up of cartilage rather than bone. It is not pivot, as a pivot joint is a type of synovial joint that only allows for rotation. It is not biaxial, as this type of joint allows for movement in two distinct directions, and the elbow joint primarily allows for movement in only one plane.

Question 5

Which joints are correctly matched?
A) interphalangeal; plane
B) ankle; hinge
C) elbow; pivot
D) wrist; saddle

Accepted Answer

The ankle joint is a hinge joint that allows movement in only one plane (dorsiflexion and plantarflexion). The interphalangeal joint is also a hinge joint, but it allows movement in only one plane (flexion and extension of the digits) and not between digits. The elbow joint is a hinge joint, but it allows movement in two planes (flexion and extension, as well as pronation and supination). The wrist joint is a condyloid joint, and the saddle joint is found in the thumb.
