Which synovial joints are found in the hand?
The six types of synovial joints are the pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints. Pivot joints are found in your neck vertebrae, while hinge joints are located in your elbows, fingers, and knees. Saddle and plane joints are found in your hands.
What are the two joint movements?
Hinge joints allow flexion and extension only. Flexion – bending a joint. This occurs when the angle of a joint decreases.
Which movement is possible at a synovial hinge joint?
flexion and extension
Hinge joints function by allowing flexion and extension in one plane with small degrees of motion in other planes. [4] The hinge joint is an essential component of the complex biomechanics of the human body. [1] The knee, elbow, and ankle can support large amounts of force and aid in the performance of work.
What type of synovial joint is the wrist?
condyloid synovial joint
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 movements of the wrist joint?
The primary movements of the radiocarpal joint are flexion, extension, abduction and adduction.
Are synovial joints freely movable?
Synovial joints are the most common type of joint in the body (see image 1). These joints are termed diarthroses, meaning they are freely mobile. A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity.
What are the 2 types of synovial joints?
Types of synovial joints
- Hinge – these can be found in the elbow, knee and ankle.
- Ball and socket – these types of joint can be found at the shoulder and hip and allow movement in almost every direction.
- Pivot – this joint can be found in the neck between the top two vertebrae.
What movement occurs at a pivot joint?
rotary movement
pivot joint, also called rotary joint, or trochoid joint, in vertebrate anatomy, a freely moveable joint (diarthrosis) that allows only rotary movement around a single axis. The moving bone rotates within a ring that is formed from a second bone and adjoining ligament.
What is the movement of wrist?
Technically, the radiocarpal joint is considered to be the only articular component of the wrist joint; many references, however, may also include adjacent joints, such as the carpal joints, in this definition….Radiocarpal joint.

Can the wrist joint rotate?
The axial rotation of the wrist also called the radiometacarpal rotation has been quantified but for its passive range which may never occur during the day-to-day routine activities. It is normally not possible for the wrist joint to rotate axially in an active manner.
