2. The place at which two things, or separate parts of one thing, are joined or united, either rigidly or in such a way as to permit motion; a juncture.
3. Done or produced together with others; such as, a joint investment.
4. To plane and to shape the edge of a board so that it fits with another edge to form a joint.

joint, joints (medical applications)
1. An articulation or the point of connection between two bones or elements of a skeleton; especially, if the articulation allows motion.

An area where two bones are attached for the purpose of the movements of certain body parts and such a joint is usually formed with fibrous connective tissue and cartilage.

2. The point, or points, of a juncture between two bones which are classified according to either their construction or based on the degree of movements which they allow.

It is classified as being immovable (synarthrosis), slightly movable (amphiarthrosis), or freely movable (diarthrosis).

  • Synarthrosis is a joint in which the two bones are separated only by an intervening membrane; such as, the cranial sutures.
  • Amphiarthrosis is a joint that has a fibrocartilaginous disk between the bony surfaces (symphysis); such as, the symphysis pubis; or one with a ligament uniting the two bones (syndesmosis); such as, the tibiofibular articulation.
  • Diarthrosis is a joint in which the adjoining bone ends are covered with a thin cartilaginous sheet and joined by a ligament lined by a synovial membrane, which secretes a lubricant.

Joints are also grouped according to motion:

  • Ball and socket (enarthrosis, a joint in which the rounded head of one bone is received into a socket, or rounded cavity, in another bone that allows motion in any direction).
  • Hinge (ginglymus, a hinge joint which is an articulation, allowing flexion and extension, or motion in just two directions like a door hinge; for example, the elbows and the ankles).
  • Condyloid (a reference to a round bump, or articular surface, on a bone where it forms a joint with another bone).
  • Pivot (trochoid, that which is capable of rotating aroung a central axis; resembling or functioning in the body like a pivot or pulley).
  • Gliding joint (arthrodia, where the joint surfaces are flat and only allow a gliding motion; such as, some wrist and ankle articulations).
  • Saddle joint (two saddle-shaped joints at right angles to each other or they permit movements of all kinds except for rotations).

facet joint (s) (noun), facet joints (pl)

Each vertebra has two sets of facet joints in which one pair faces upward (superior articular facets) and one pair faces downward (inferior articular facets).

Facet joints are synovial in that each joint is surrounded by a capsule of connective tissue which produces a fluid to lubricate all of them so they can move or slide (articulate) with each other.

A medical process that destroys the small nerve branches that send pain signals from the facet joint: Facet-joint coagulations are performed with the patient lying on his or her stomach.

A mobile X-ray unit is used to determine the optimal localization for the coagulation needle in the facet-joint coagulation procedure.

During the treatment of the facet-joint coagulation, the selected nerve is destroyed by heat that lasts for a few seconds; but because of the anesthesia, it should not be felt by the patient.

knee joint (s) (noun), knee joints (pl)
The point at which two bones meet between the femur (thigh bone) and the tibia (shin): The knee joint is a modified hinge or junction that is capable of slight rotation in a bent position.

Each of these wedge-shaped crescents of knee joints have shock absorbers that resist impacts when running, jumping, etc.

Violent rotational movements of the thighs or legs while the knee joints are flexed; as in, football, soccer, skiing, or other sports, can severely damage the menisci or cartilage disks when they are squeezed between the bones of the knee joints.

sutural joint (s) (noun), sutural joints (pl)
An articulation between two bones; that is, the point of connection between two bones or elements of a skeleton; especially, if the articulation allows motion.

An area where two bones are attached for the purpose of moving body parts.

An articulation, or joint, is usually formed of fibrous connective tissue and cartilage and the joints are grouped according to their motion:

  • A ball and socket joint.
  • A hinge joint.
  • A condyloid joint (a joint that permits all forms of angular movement except axial rotation).
  • A pivot joint.
  • A gliding joint.
  • A saddle joint
  • Joints can move in four and only four ways:

  • Gliding, one bony surface that glides on another without angular or rotatory movement.
  • Angular, occurs only between long bones, increasing or decreasing the angle between the bones.
  • Circumduction, occurs in joints composed of the head of a bone and an articular cavity, the long bone describing a series of circles, the whole forming a cone.
  • Rotation, a bone that moves around a central axis without moving from this axis.

synovial joint (s) (noun), synovial joints (pl)
Joints where two bones articulate (come together) to allow a variety of motions where the union of the bony elements are surrounded by an articular capsule enclosing a cavity lined by a synovial membrane.

These joints include "ball and socket joints"; such as, the hips and shoulders that permit a wide range of movements in several directions; and the "hinge joints"; such as, the knees and elbows which allow movements primarily in one direction or plane.

Synovial joints consist of several components which make complex movements possible

  • Synovial capsule, the outermost layer of strong fibrous tissue which resembles a sleeve as it surrounds the joint.
  • Synovial membrane which lines the capsule and secretes synovial fluid.
  • Synovial fluid, which flows within the synovial cavity, acts as a lubricant to make the smooth movement of the joint possible.
  • Ligaments, bands of fibrous tissue that form joints by connecting one bone to another bone, or joining a bone to cartilage and complex hinge joints; such as, the knee, are made up of a series of ligaments which permit movements in different directions.
  • Bursa (s), bursae (pl), a fibrous sac which acts as a cushion to ease movement in areas that are subject to friction; such as, in the shoulder, elbow, and knee joints; where a tendon passes over a bone.

temporomandibular joint syndrome
A disorder of the temporomandibular joint that causes pain, usually in front of the ear or ears, sometimes in the form of a headache.

Pain in the temporomandibular joint can be caused by trauma; such as, a blow to the face, inflammatory or degenerative arthritis; or poor dental work or structural defects that push the mandible back toward the ears whenever the patient chews or swallows. Grinding or clenching the teeth is a frequent cause.

Sometimes muscles around the temporomandibular joint that are used for chewing can go into spasms, causing head and neck pain, as well as difficulty opening the mouth normally.

The kind of medical treatment depends on the cause and severity of the problem and can range from use of a mouth guard or medication to prevent night time tooth grinding to surgery.

joint (s), joints (pl)
Smoothly curved fracture, or fractures, in a rock.

Joints can be small or up to thousands of feet long. Hundreds of joints may appear in a single outcropping of rock.

A joint system consists of two or more sets of joints that are arranged in characteristic patterns; such as, concentric, radial, etc.

The jointing of rock formations is a major factor of geological changes resulting from weathering and erosion.

The movement of the rock at right angles to this fracture can produce an open joint, or fissure. If the movement of the rocks of a joint is parallel to the surface of the fractures, the resulting break is classified as a fault.
