What joints are biaxial hinge joints?
Biaxial joints allow for movement in two planes or axes. A common example of a biaxial joint is the wrist, which allow for movement side to side, and also allows for movement up and down. It can be difficult to determine whether a joint is biaxial or multiaxial, because when the biaxial joint moves in both directions at the same time, it appears to have the multiaxial quality of being able to move in any plane or axes.
What are joints characterized by?
Answermovementnot all joints allow for movement. some fibrous joints and some cartilaginous joints do not move. BUT the two fundamental functions of joints are to give our skeleton mobility, and to hold it together.They all hold the bones together!
What are the types of joints found in thumb?
The types of joints found in thumb are: 1. Caropometacarpal joint where the metacarpal bone of the thumb attaches to the trapezium bone of the wrist. This joint is a saddle joint that allows two planes of motion with a small amount or rotation. 2. Metacarpophalangeal joint is the joint between the metacarpal bone and the phalanges of the thumb. This joint is an ellipsoid joint that allows movement in two planes and is biaxial. 3. Interphalangeal joint is the joint between the two phalanges of the thumb. This joint is a hinge joint that allows movement in one plane and is also referred to as uniaxial.
How do joints allow movement?
The two main functions of joints are for support and movement. Joints allow you to move your body and to support it and hold the bones together.
What are the two jobs that joints provide for the skeletel system?
it provides shape for your body and movement

What is the name of a muscle that crosses two joints?
rectus femoris
What are the muscles called that cross two joints and act on both joints?
biarticulate or biaxial muscles
Demonstrate movement at two joints that are uniaxial?
Flexion ( is a typical of hinge joint ) bending the knee or elbow
What Two ways that joints are classified?
There are several ways in which joints are classified. The main classifications are in regard to how much they move. The classical terms are Synarthrotic, Amphiarthrotic, and Diarthrotic, where the Diarthrotic are the most movable. The diarthrotic joints are also called freely moving, or synovial joints. These can be classified by how they move. There are monoaxial joints, which move in one plane, or around a central axis. Then there are biaxial joints that move in two planes of movement. And, finally, there are the multiaxial (sometimes called triaxial) joints that move in more than two planes. The monoaxial joints can be subdivided into hinge and pivot joints. The biaxial joints can be subdivided into ellipsoidal and saddle. And, the multiaxial joints can be subdivided into gliding and ball-and-socket joints.
What motion occurs in the thumb?
This is a saddle joint which allows movement in two planes instead of one. It allows the thumb to cross the palm of the hand. This joint allows biaxial movement. This allows movement in the frontal and sagittal planes.

What are the optical character?
There are two types uniaxial or biaxial.

Which joint moves only by a uniaxial movement around its own axis?
the pivot and hinge joints. they can only move back and forth in one direction, as apposed the the biaxial joint, condyloid, and saddle which can move back and forth in 2 different directions and the multiaxial joint Ball and socket joint which can move in many directions.
What two joints does the gastrocenimicis act on?
The knee joint (flexion, movement of the leg) and the ankle joint (plantarflexion, movement of the foot)
