What are the joints of the wrist and hand?
Joints of the Wrist and Hand
| Joint | Proximal articulation | Type |
|---|---|---|
| Radiocarpal joint | Radius and articular disc/ concave | Ellipsoid |
| Midcarpal joint | Scaphoid. Lunate, Triquetrum | Gliding |
| Carpometacarpal joint (thumb) | trapezium | Saddle |
| Carpometacarpal joint (fingers) | trapezoid, trapezium capitate capitate, hamate hamate | Ellipsoidal |
What type of joint movement is the wrist?
The wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.
What are the 3 major types of joints and how movable are they?
There are three types of joints in the functional classification: immovable, partly movable, and movable joints.
- Immovable joints allow little or no movement at the joint. Most immovable joints are fibrous joints.
- Partly movable joints permit slight movement.
- Movable joints allow bones to move freely.
What are the 3 wrist joints?
There are three joints in the wrist:
- Radiocarpal joint: This joint is where the radius, one of the forearm bones, joins with the first row of wrist bones (scaphoid, lunate, and triquetrum).
- Ulnocarpal joint: This joint is where the ulna, one of the forearm bones, joins with the lunate and triquetrum wrist bones.
What are the wrist movements?
Collectively called a condyloid joint, the many connection points of the wrist allow for the movements of flexion and extension, supination and pronation, as well as ulnar deviation and radial deviation, which is the hand-waving motion of lateral flexion.
What kind of joints are in the hand?
The joints in the hand are joints found at the distal end of the upper limb. The joints are: In the wrist there is the radiocarpal joint between the radius and carpus. Between the carpal bones are the intercarpal articulations and the midcarpal joint….Joints of hand.

What are joints explain different types of joints?
Joints aka articular surface can be defined as a point where two or more bones are connected in a human skeletal system. Cartilage is a type of tissue which keeps two adjacent bones to come in contact (or articulate) with each other. 3 Types of joints are Synovial Joints, Fibrous Joints, and Cartilaginous Joints.
How do the different joints differ from each other?
Fibrous joints contain fibrous connective tissue and cannot move; fibrous joints include sutures, syndesmoses, and gomphoses. Cartilaginous joints contain cartilage and allow very little movement; there are two types of cartilaginous joints: synchondroses and symphyses.
What are the different types of wrist movements?
The wrist is a complex series of joints that are formed around the carpal bones and the radius and ulna (forearm bones). The wrist is capable of three sets of distinct movements. Flexion and extension. Supination and pronation. Ulnar deviation (ulnar flexion) and radial deviation (radial flexion)

What are the different types of movement in synovial joints?
The wide range of movement allowed by synovial joints produces different types of movements. The movement of synovial joints can be classified as one of four different types: gliding, angular, rotational, or special movement.
Which is type of joint allows movement along two axes?
Condyloid joints consist of an oval-shaped end of one bone fitting into a similarly oval-shaped hollow of another bone. This is also sometimes called an ellipsoidal joint. This type of joint allows angular movement along two axes, as seen in the joints of the wrist and fingers, which can move both side to side and up and down.
