ligament (redirected from ligament arteriosum)

ligament (lĭg`əmənt), strong band of white fibrous connective tissue that joins bones to other bones or to cartilage in the joint areas. The bundles of collagenous fibers that form ligaments tend to be pliable but not elastic. They therefore permit freedom of movement within a certain limited range while holding the attached bones firmly in place. For example, the ligaments at the knee limit the movement of the lower leg to a certain range. Other types of ligaments form fibrous sheets that support such internal organs as the kidneys and the spleen.

ligament

Tough fibrous band of connective tissue that supports internal organs and holds bones together properly in joints. It is composed of dense bundles of fibres and spindle-shaped cells (fibroblasts and fibrocytes), with little ground substance. White ligament is rich in sturdy, inelastic collagen fibres; yellow ligament is rich in tough elastic fibres, which allow more movement. See also tendon.

Ligament

A strong, flexible connective tissue band usually found between two bony prominences. Most ligaments are composed of dense fibrous tissue formed by parallel bundles of collagen fibers. They have a shining white appearance and are pliable, strong, and noncompliant. A second kind of ligament, composed either partly or almost entirely of yellow elastic fibers, is extensible or compliant, thereby allowing the connected bones to move apart.
