ligament

a capsule of elastic CONNECTIVE TISSUE that joins bones. Ligaments are composed of tightly packed elastic fibres which surround a joint. They prevent dislocation of joints, support bones, and hold the skeleton together, and are ideally suited to withstanding sudden stresses applied to the joints.

Ligament

Ligaments are structures that hold bones together and prevent excessive movement of the joint. They are tough, fibrous bands of tissue.

ligament

a strong band of fibrous connective tissue, which binds bones together. Ligaments may form part of the capsule around a joint or be within the joint itself, such as the cruciate ligaments of the knee. Ligaments need to be flexible, to facilitate joint movement, but relatively non-elastic to provide strength and stability and to limit the range and direction of movements at a joint.

ligament

band or sheet of fibrous tissue linking two or more bones, cartilages or other structures, or serving as fascial or muscle support (see collateral ligament)

ligament,

n strong connective tissue that binds the bones of the skeleton together at the joints.

ligament

A tough, flexible band of white fibrous tissue that connects the articular extremities of bones, or supports an organ in place.
check ligament A strong band of connective tissue which leaves the surface of the sheath of the extraocular muscles and attaches to the surrounding tissues, so as to limit the action of the muscle. The medial rectus is attached to the lacrimal bone (medial check ligament) and the lateral rectus to the zygomatic bone (lateral check ligament). There are also check ligaments restricting the vertical movements but the expansions of these muscles are thinner and less distinct than those of the horizontal recti muscles.
hyaloideocapsular ligament See ligament of Wieger.
ligament of Lockwood The lower part of the capsule of Tenon's capsule and parts of the tendons of the inferior rectus and oblique muscles which are thickened to form a hammock-like structure on which the eyeball rests.
palpebral ligament Strong connective tissue attaching the extremities of the tarsal plates of the upper and lower eyelids to the orbital margin. There are two sets: (1) the lateral palpebral ligament (lateral canthal tendon) about 7 mm long and 2.5 mm wide which constitutes the deeper portion of the lateral palpebral raphe of the orbicularis muscle and attaches the tarsal plates to the lateral orbital tubercle (Whitnall's tubercle) on the zygomatic bone and (2) the medial palpebral ligament (medial canthal tendon) which attaches the medial ends of the tarsal plates to the frontal process of the maxilla and another insertion into the posterior lacrimal crest. It lies anterior to the canaliculi and the lacrimal sac.
suspensory ligament A ligament whose principal function is to support another structure, e.g. ligament of Lockwood, the zonule of Zinn.
ligament of Wieger An attachment of the anterior surface of the vitreous humour to the posterior lens capsule in the shape of a ring about 8-9 mm in diameter. It forms a line called Egger's line. This adherence is strong in youth but weakens with age enabling intracapsular cataract extraction without pulling the vitreous. Syn. hyaloideocapsular ligament.

(lig'ă-mĕnt) [TA]
1. Band or sheet of fibrous tissue connecting two or more bones, cartilages, or other structures, or serving as support for fasciae or muscles.
2. Fold of peritoneum supporting any of the abdominal viscera.
3. Any structure resembling a ligament without such function.
Synonym(s): ligamentum.
[L. ligamentum, a band, bandage]

ligament (lig´əment),

n the principal fibers of periodontal ligament, made up of five groups: alveolar crest, horizontal, oblique, apical, and interradicular (if multirooted).
ligament, biologic width of periodontal,
n the width of the periodontal ligament in normal, functioning teeth. It varies with the age of the individual and the functional demands made on the tooth. In health, the periodontal ligament is about 0.25 and 0.1 mm in width, narrowest at the center of the alveolus and widest at the margin and apex.
ligament, periodontal (PDL),
n the method of attachment of the tooth to the alveolus. The ligament consists of numerous bundles of collagenous tissue (principal fibers) arranged in groups, between which is loose connective tissue, together with blood vessels, lymph vessels, and nerves. It functions as the investing and supportive mechanism for the tooth. Older term:
periodontal membrane.

Patient discussion about ligament

Q. Is ligament heating better than an arthroscopic surgery? I have a partial tear in my left knee (acl) and they wanna operate on me. I heard heating it can solve the problem. is it true?

A. i never heard of "ligament heating" from what i know- ligament has limited ability to regenerate. if partially torn it may need only physiotherapy and care. but if it's torn more then it can heal by itself- you need surgery. this is why there's orthopedics- to evaluate the situation, give you a diagnosis and the recommended treatment. it's always good to second guess because they are only human. you can ask other orthopedics and see what they say.

Q. I did a bad movement with my knee during a ball game. How can I know if I damaged the knee ligaments? 4 hours ago I played basketball. I did a great jump but when I landed I felt a very sharp knee pain? How can I know if I damaged the ligaments there?

A. The only way to know for sure is to check! Can estimate the severity of the problem. Is your knee red? Is it hot? Is it swollen? Does the pain have the same severity or does the pain increase with time? If you answered one of those questions with a 'yes' several hours after the injury, you should probably talk to your GP
