Since the annular ligament is attached loosely to the neck of the radius, the lower part of the proximal radioulnar joint is weak. In addition to the extremely common ligament sprains that nearly everyone experiences at some point in his or her life, ligaments can also calcify later in life. Path: Anterolaterally (Fig. Home pennsylvania flooding map 2021 iliofemoral ligament origin and insertion. As a similar ligament is also present in turtles, he argued for a diapsid origin of this group. Action: adducts thigh. 6). This attachment is superior to the origins of adductor magnus muscle and lateral to the obturator externus muscle. The taxon Beloniformes represents a heterogeneous group of teleost fishes that show an extraordinary diversity of jaw morphology. Deep 1/4th -Gluteal tuberosity B.

The origin is the fixed attachment, while the insertion moves with contraction. Its borders are strengthened by fibers from the upper border of the annular ligament . • The lateral collateral ligament. The gluteal region, or buttock, is bounded superiorly by the iliac crest and inferiorly by the fold of the buttock, The region is largely made up of the gluteal muscles and a thick layer of superficial fascia.It is located posteriorly to the pelvic girdle, at the proximal end of the femur. Synonym: musculus quadratus lumborum, lumbar quadrate muscle, quadrate muscle of loins. . It is always taut when the forearm is supinating or pronating. In Desmogna-thus, Leurognathus, and probably Phaeognathus, the origin is also from the ventrolateral surface of the mandible just anterior to its articulation with the quadrate (Figs. • Origin: usually more proximal • Insertion: usually more distal • Contraction produces equal force on the two attachments . Upper half of posterior shaft of tibia and upper half of fibula between medial nerve crest and interosseous border, and interosseous membrane.

In other amniotes, this ligament is either detached from the quadrate in mammals (i.e. O: head of fibula, posterior proximal fibula, soleal line (tibia), I: calcaneus. The Quadratus Lumborum (QL) is the deepest back muscle and originates from the iliac crest and inserts on the transverse process of lumbar one through five and the lower part of the twelfth rib. The quadrate ligament is a fibrous band attached to the inferior border of the radial notch on the ulna and to the neck of the radius. [1, 2] As such, the UCL plays an important role in most throwing sports, including baseball and javelin, as well as racquet sports and ice hockey.Elbow injuries in young athletes are generally chronic, with persistent pain and instability from repetitive overhead .

The femur is the only bone in the upper leg. It arises dorsally and ventrally from the medial palpebral ligament and encircles the palpebral fissure. The coracobrachialis is generally pierced by the musculocutaneous nerve. It runs parallel to the tibia and plays a notable role in stabilizing the ankle joint and supporting the muscles of the lower leg. Insertion: Middle phalanges of digits 2-5. OBTURATOR INTERNUS Origin: Internal or pelvic surface of the obturator membrane and margin of the obturator foramen, pelvic surface of the ischium posterior and proximal to the obturator foramen, and to a slight extent, the obturator fascia. Side of coccyx 5. A reduction of the external jaw adductor (A1) and a changed morphology of the intramandibular musculature were found in many Beloniformes.
