an·te·ri·or cru·ci·ate lig·a·ment

the ligament that extends from the anterior intercondylar area of the tibia to the posterior part of the medial surface of the lateral condyle of the femur.

anterior cruciate ligament (ACL)

a strong band that arises from the posterior middle part of the lateral condyle of the femur, passes anteriorly and inferiorly between the condyles, and is attached to the depression in front of the intercondylar eminence of the tibia. The ACL is often injured in athletic activity and is the main control for rotation of the knee.

(an-tēr'ē-ŏr krū'shē-ăt lig'ă-mĕnt) [TA]
The ligament that extends from the anterior intercondylar area of the tibia to the posterior part of the medial surface of the lateral condyle of the femur.
Synonym(s): ligamentum cruciatum anterius [TA] .


situated at or directed toward the front; opposite of posterior. In quadrupeds the use of the term is limited to parts of the head but is often used to mean cranially. In bipeds such as humans it is synonymous with ventral.

anterior abdomen pain
elicited pain in the anterior abdomen caused, in cattle, by reticulitis, hepatic or splenic abscess, abomasal ulcer and intestinal obstruction.
anterior chamber
the part of the eyeball between the cornea and the iris, filled with aqueous humor.
anterior chamber angle
see iridocorneal angle.
anterior compartment
chamber of the eye bounded by the iris and cornea; contains the aqueous humor as it moves to the filtration angle; called also anterior chamber.
anterior cruciate ligament
see cranial (anterior) cruciate ligament.
anterior (cranial) drawer sign
cranial, nonrotary movement of the proximal tibia in relation to the distal femur. Normally restricted by the cranial (anterior) cruciate ligament and used as a diagnostic test for rupture of that structure.
anterior epithelial layer
of the cornea is a noncornified, stratified, squamous epithelium, continuous with the bulbar conjunctival epithelium.
anterior functional stenosis
achalasia of the reticulo-omasal sphincter causing ingesta to accumulate in the reticulorumen.
anterior limiting membrane
of the cornea is a combination of the basement membrane, a felted layer of fine collagen fibers; substantial only in primates.
anterior pituitary
anterior pituitary hormones
anterior station trypanosomes
a section of the genus Trypanosoma in which the infectious stages accumulate in the mouthparts and salivary glands of the intermediate host so that the parasite is transmitted when the insect vector takes a blood meal. Called also Salivaria. See also posterior station trypanosomes.

Prior to this study, it had been presumed that a bone bruise seen with MRI at the time of an acute anterior cruciate ligament (ACL) injury might lead to later degenerative changes because bruising can be associated with necrosis of osteocytes and subchondral bone.
