Question

Answer 1

A- Hinge

The hinge joints allow movement in one plane resembling that of a door hinge.

Answer 2

A) hinge

Step-by-step explanation:

A hinge joint refers to a bone joint that the way its articular surfaces are molded allows only one plane motion. Hinge joints are uniaxial because they have just only one degree of freedom or movement of the bones can only occur along one axis to flex or extend, and their formations occur among two or more bones.

Examples of hinge joint which is a common type of synovial joint are the elbow, knee, interphalangeal and ankle joints.

The interphalangeal joint which is between the phalanges of the fingers and toes is regarded as the simplest hinge joints because the bones can flex to reduce the angle between them.

The elbow joint on the other hand is considered as a complex hinge joint due to the fact the forces it experiences are much stronger that what knuckles of the fingers and toes experience.
