How do tendons and ligaments help us move?
Our bones, muscles and joints work together in a coordinated way to move our body and give it stability. Tendons and ligaments play an important role here, too: Tendons connect muscles to bones, allowing us to move, and ligaments help to hold things in place.
What are the ligaments of the elbow joint?
The two main ligaments connecting the humerus and ulna are: ulnar-collateral ligament, also called the medial collateral ligament, which runs along the inside of the elbow. lateral collateral ligament, also called the radial collateral ligament, which runs along the outside of the elbow.
Which ligaments stabilize the medial and lateral surfaces of the elbow joint?
The medial elbow is supported by the ulnar collateral ligament and the radial collateral ligament supports the lateral side. These ligaments prevent side-to-side movements and resist hyperextension of the elbow.
How do ligaments allow movement?
Ligaments are tough fibrous cords composed of connective tissue that contains both collagen and elastic fibers. The elastic fibers allow the ligaments to stretch to some extent. Ligaments surround joints and bind them together. They help strengthen and stabilize joints, permitting movement only in certain directions.
How do ligaments help movement?
Ligaments surround joints and bind them together. They help strengthen and stabilize joints, permitting movement only in certain directions. Ligaments also connect one bone to another (such as inside the knee).
What is the role of ligaments in the elbow joint?
Ligaments are strong rope like tissue that connects bones to other bones and help hold tendons in place providing stability to joints. Ligaments around the elbow join to form a watertight sac called a joint capsule. This capsule surrounds the elbow joint and contains lubricating fluid called synovial fluid.
What ligaments stabilize the elbow?
The important ligaments of the elbow are the medial collateral ligament (on the inside of the elbow) and the lateral collateral ligament (on the outside of the elbow.) Together these ligaments provide the main source of stability for the elbow, holding the humerus and the ulna tightly together.
What are the ligaments and tendons in the elbow?

Ligaments around the elbow join to form a watertight sac called a joint capsule. This capsule surrounds the elbow joint and contains lubricating fluid called synovial fluid.
How are the bones of the elbow held together?
The Anatomy of the Elbow. The elbow is a hinged joint made up of three bones, the humerus, ulna, and radius. The ends of the bones are covered with cartilage. Cartilage has a rubbery consistency that allows the joints to slide easily against one another and absorb shock. The bones are held together with ligaments that form the joint capsule.
How does the elbow joint work with the wrist joint?
The joints also work together with the wrist joint to allow us to turn our hand palm up (supination) and palm down (pronation). The three bones that make up the elbow joint are the humerus (upper arm,) and the two bones of the forearm, the radius and ulna.
Are there two muscles that produce flexion at the elbow joint?
There are two muscles in this compartment that produce flexion at the elbow joint: Movements at a hinge joint. Biceps Brachii originates as two heads. Brachialis originates from the distal half of the anterior surface of the humerus, as well as from the intermuscular septa on either side of the anterior compartment.
