The movements of bones are limited by the morphology of the joints which connect them. Some joints allow movement in only one plane; these joints are uniaxial. One common uniaxial joint is the hinge joint.
Which type of joint allows for only uniaxial movement?
This type of joint allows only for bending and straightening motions along a single axis, and thus hinge joints are functionally classified as uniaxial joints. A good example is the elbow joint, with the articulation between the trochlea of the humerus and the trochlear notch of the ulna.
What are non axial joints?
What is a non axial joint? Joints, such as the intertarsal joints, which allow only a very limited movement (e.g. side to side, or back and forth). From: non-axial joints in The Oxford Dictionary of Sports Science & Medicine » Subjects: Medicine and health — Clinical Medicine.
Is the atlantoaxial joint uniaxial?
The pivot joint is another type of synovial uniaxial joint. A pivot joint allows only rotation (pivot) motions in the transverse plane around a vertical axis. The atlantoaxial joint of the spine is a classic example of a uniaxial pivot joint ( Figure 2-5 on page 45 ).

What joints are biaxial?
There are three types of biaxial joint: condyloid, ellipsoid and saddle.
What are the 2 uniaxial synovial joints?
There are two types of synovial uniaxial joints: (1) hinge and (2) pivot. Hinge joints act similar to the hinge of a door. One surface is concave and the other is shaped similar to a spool. Flexion and extension are allowed in the sagittal plane around a mediolateral axis.
Are hinge joints uniaxial or biaxial?
uniaxialHinge joints: These joints only permit flexion and extension and are also uniaxial. An example of this type of joint is the elbow joint. Saddle joints: These joints are as the name suggests shaped like a saddle, and permit movement in two separate planes and are termed biaxial joints.
Which joints are Nonaxial?
Examples are the gliding joints introduced earlier—the intercarpal and intertarsal joints, and the joints between vertebral articular processes. Gliding does not involve rotation around any axis, and gliding joints are the only examples of nonaxial plane joints.
Is the shoulder joint uniaxial?
The shoulder and hip joints are multiaxial joints. They allow the upper or lower limb to move in an anterior-posterior direction and a medial-lateral direction.
Is a pivot joint uniaxial?
Pivot (a.k.a. trochoidal) joints are also uniaxial joints. They allow rotary movement around one axis that is longitudinal through the bone.
Is knee joint biaxial joint?
The knee joint, also known as the tibiofemoral joint, is a synovial joint. More specifically, it is a biaxial, modified hinge joint.
Is the wrist joint biaxial?
The wrist joint proper is a biaxial, ellipsoid joint between the distal end of the radius and the articular disc, and the proximal row of carpal bones.
Are Condyloid joints uniaxial?
Functionally, condyloid joints are biaxial joints that allow for two planes of movement.
Is the elbow joint uniaxial or biaxial?
Synovial: Hinge This type of joint is uniaxial because it only permits movement in one axis. In the body, this axis of movement is usually bending and straightening, or flexion and extension. Examples include the elbow, knee, ankle, and interphalangeal joints.
Is a gliding joint uniaxial or biaxial?
Nonaxial (gliding): Found between the proximal ends of the ulna and radius. Monoaxial (uniaxial): Movement occurs in one plane. An example is the elbow joint. Biaxial: Movement can occur in two planes.
Is the plane joint Nonaxial?
Yes, plane joints are nonaxial. This is because the bones that form the joint do not create an angle when they move in relation to each other in the way we see with joints like the elbow.
Are Condyloid joints uniaxial?
Functionally, condyloid joints are biaxial joints that allow for two planes of movement.
What is meant by uniaxial biaxial and multiaxial?
Monoaxial (uniaxial): Movement occurs in one plane. An example is the elbow joint. Biaxial: Movement can occur in two planes. An example is the wrist. Multiaxial: Includes the ball and socket joints.
What are ball and socket joints?
ball-and-socket joint, also called spheroidal joint, in vertebrate anatomy, a joint in which the rounded surface of a bone moves within a depression on another bone, allowing greater freedom of movement than any other kind of joint.
Is knee joint biaxial joint?
The knee joint, also known as the tibiofemoral joint, is a synovial joint. More specifically, it is a biaxial, modified hinge joint.
What is the classification of a joint?
The functional classification of joints is determined by the amount of mobility found between the adjacent bones. Joints are thus functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, which is a freely moveable joint (arthroun = “to fasten by a joint”). Depending on their location, fibrous joints may be functionally classified as a synarthrosis (immobile joint) or an amphiarthrosis (slightly mobile joint). Cartilaginous joints are also functionally classified as either a synarthrosis or an amphiarthrosis joint. All synovial joints are functionally classified as a diarthrosis joint.
What is a freely mobile joint?
A freely mobile joint is classified as a diarthrosis. These types of joints include all synovial joints of the body, which provide the majority of body movements. Most diarthrotic joints are found in the appendicular skeleton and thus give the limbs a wide range of motion. These joints are divided into three categories, based on the number of axes of motion provided by each. An axis in anatomy is described as the movements in reference to the three anatomical planes: transverse, frontal, and sagittal. Thus, diarthroses are classified as uniaxial (for movement in one plane), biaxial (for movement in two planes), or multiaxial joints (for movement in all three anatomical planes).
What is an amphiarthrosis joint?
An amphiarthrosis is a joint that has limited mobility. An example of this type of joint is the cartilaginous joint that unites the bodies of adjacent vertebrae. Filling the gap between the vertebrae is a thick pad of fibrocartilage called an intervertebral disc ( [link] ). Each intervertebral disc strongly unites the vertebrae but still allows for a limited amount of movement between them. However, the small movements available between adjacent vertebrae can sum together along the length of the vertebral column to provide for large ranges of body movements.
