Coracoacromial Ligament
Location: clavicular articulating surface of the acromion
Function: forms the coracoacromial arch over the head of the humerus
Coracoclavicular Ligament
Location: clavicular articulating surface of the acromion
Function: attach the clavicle to the coracoid process of the scapula
: Coracohumeral Ligament
Location: superficial to the glenohumeral ligaments
Function: Part of the ligament integrates with the superior glenohumeral ligament inferiorly, while another portion covers the biceps tendon anterior to the joint.
Superior Glenohumeral Ligament
Location: extends from supraglenoid tubercule of scapula to the proximal aspect of the lesser tubercle of humerus
Function: supports the rotator interval and prevents inferior translation of the humeral head,
Inferior Glenohumeral Ligament
Location: extends between glenoid labrum and inferomedial part of humeral neck.
Function: Both bands stabilize the humeral head abducted above 90°.
Lateral collateral Ligament
Location: It extends from the anterior aspect of the malleolus to the lateral surface of the talar neck
Function: connects the talus with the lateral malleolus of the fibula
Acromioclavicular Ligament
Location: which attaches to the acromion process at one end and the clavicle at the other
Function: Supports the acromioclavicular joint
Middle Glenohumeral Ligament
Location: attaches along the anterior glenoid margin of the scapula,
Function: It stabilizes the anterior capsule, limiting external rotation,
Medial Collateral Ligament
Location: attaches to the medial malleolus proximally and to the calcaneus,
Function:
Annular Ligament
Location: The radius
Function: Support to the proximal radioulnar joint
Iliofemoral Ligament
Location: lies on the anterior and superior aspects of the hip joint,
Function: to prevent hyperextension of the hip joint when standing.
Pubofemoral Ligament
Location: It arises from the iliopubic ramus, the superior pubic ramus and the obturator crest of the pubic bone
Function: reinforces the anterior and inferior aspects of the joint capsule
Ischiofemoral Ligament
Location: It is attached medially to the ischial bone below the acetabulum.
Function: strengthens the posterior aspect of the joint capsule
Ligamentum teres
Location: Its apex attaches to the fovea capitis while its base attaches to the acetabular notch
Function: carries a small branch of the obturator artery, the artery to the head of the femur for blood supply
Anterior Collateral
Ligament
Location: knee
Function: it essentially acts to prevent too much forward movement
Medial Collateral Ligament
Location: supporting structure on the medial part of the knee joint
Function: Its primary function is to resist valgus (twisting outwards away from the mid-line)
Anterior talofibular
ligament
Location: attaches to the neck of the talus
Function: to resist inversion and plantar flexion of the ankle joint.[
Posterior Collateral
Ligament
Location: . They attach the tibia to the femur
Function: Prevents anterior displacement of the femur on tibia
Lateral Collateral Ligament
Location: ligament that originates from the lateral epicondyle of the femur
Function: the ligament splits the tendon of biceps femoris muscle in two.
Calcaneofibular Ligament
location: , it extends from the depression located anterior to the apex of the lateral malleolus of the fibula
function: Stabilize the ankle joint.
Posterior Collateral
Ligament
Location: arises from the posterior intercondylar area of the tibia
Function: prevents anterior rolling and displacement of the femoral condyle during extension
Ligamentum nuchae
Location: back of the neck that extends between the base of the skull and C7 in the midline
Function: to support the head
Supraspinous ligament
Location: ns along and connects the tips of the spinous processes from vertebra C7 to the sacrum
Function: This ligament prevents separation of spinous processes during flexion
Anterior longitudinal
ligament
Location: This ligament attaches superiorly to the occipital bone, anterior to the foramen magnum
Function: prevents hyperextension of the spine.
Posterior longitudinal
ligament
Location: runs along the posterior surfaces of the vertebral bodies within the vertebral canal.
Function: It resists hyperflexion of the vertebral column and helps prevent posterior herniation of the nucleus pulposus of an IV disc.
Interspinous Ligament
Location: attaches from the base to the apex of each spinous process,
Function: The interspinous ligaments connect adjacent vertebral spinous processes
Intertransverse Ligament
Location: They extend from the upper border of the transverse process of one vertebra to the lower border of the transverse process
Function: The main function of these ligaments is to limit lateral flexion of the vertebral column.
Ligamentum Flavum
Location: Each ligament runs almost vertically from the anterior surface of the lamina above to the posterior surface of the lamina
Function: to resist separation of the laminae during flexion
