The word "socket joint" is spelled with the IPA /ˈsɒk.ɪt dʒɔɪnt/. In this phonetic transcription, the first syllable "sock" sounds like "sahk", and the second syllable "et" sounds like "it". The phonetic transcription of "joint" is /dʒɔɪnt/, with the first syllable "joi" sounding like "joy". A socket joint, also known as a ball and socket joint, is a type of joint in which one bone has a spherical head that fits into a concave socket of another bone, allowing for a wide range of movement.
A socket joint, also referred to as a ball and socket joint, is a type of joint in the human body or a mechanical device that enables movement in various directions. This joint consists of a spherical-shaped head and a concave socket or cup-like structure that holds and allows rotation of the ball-like end.
In the human body, socket joints are commonly found in the hips and shoulders, where they provide a high degree of mobility and stability. These joints allow movement in multiple planes, such as flexion, extension, abduction, adduction, and rotation. The spherical head of the bone fits snugly into the socket, forming a pivot point that allows smooth movement.
In mechanical devices, socket joints are utilized to create connections that allow rotation and movement along multiple axes. They are commonly found in machinery and tools, such as ball and socket joint adapters, hinges, and universal joints. These joints offer flexibility and versatility in movement, enabling the objects or components to adjust to different angles and positions.
Socket joints require proper lubrication to ensure smooth movement and reduce friction between the ball and socket surfaces. This lubrication is often provided by synovial fluid in the human body or lubricants in machinery and devices.
Overall, socket joints are essential components in both the human body and various mechanical systems, enabling a wide range of movements and providing stability and flexibility.

The word "socket" derives from the Old French word "soquet", which means "shoe" or "sleeve". It is related to the Latin word "soccus", meaning "slipper" or "light shoe".
The term "joint" comes from the Old French word "joint", derived from the Latin word "junctus", which means "joined" or "connected".
Combining both words, "socket joint" refers to a type of joint where one bone fits into a cup-shaped cavity or socket in another bone, allowing movement and flexibility between the two.
