An acute strain of the muscle or tendon structure happens at the connection where the muscle is becoming a tendon. These strains occur when a muscle is stretched or suddenly is contracted (Sutton, n.d). 3. What are the four major ligaments of the knee along with their individual function in respect to the femur? (1 point) The medial Collateral Ligament also known as the MCL is a band that runs in between the inner surfaces of the femur and the tibia.
Joints are where two or more bones meet. They allow the rigid skeleton to move, surrounding soft tissues hold each joint together. Muscles lie over one or more joints at the lower back and extend upwards to the trunk and downwards to the pelvis. At both ends the muscle changes into a tendon by which it attaches itself to different
In the periosteum it surrounds the bone surface wherever it is not covered by articular cartilage, it is a sheath of dense irregular connective tissue containing osteoblasts, it functions to protect the bone, assists in fracture repair, nourishes bone tissue, and serves as an attachment point for ligaments and tendons. 4- Which kind of bone marrow is in spongy bone tissue? Red bone marrow is the type of marrow found in spongy bone tissue. 5- Which ossification method would form a femur? Endochondrial ossification would form the femur.
A prominent ridge called the spine runs diagonally across the posterior surface of the scapula. Hassan could have identified which were right and left, possibly by the medial border because the thick edge (lateral border) is closer to the arm. The glenoid cavity is the shallow depression that articulates with the head of the humerus. B. Which bone is Stefan referring to as the collarbone?
8. What is the orbit? ____________________________________________________________ ________________________ The frontal bone,lesser and greater wings of sphenoid, What bones contribute to the formation of the orbit? _________________________________________________________ zygomatic, maxilla,palatine ,lacrimal bone and ethmoid bone. ____________________________________________________________ ______________________________________ It forms a central wedge that articulates 9.
Wehbe 1 The ACL is a cruciate ligament that is one of four primary stabilizing ligaments in the human knee. The ACL is important for knee stability, acting as the primary restraint to anterior translation of the tibia on the femur (Cameron). This ligament also functions as a secondary restraint to forces of varus, valgus and internal/external rotation. It is located at the center of the knee, consisting of two bundles of fibers – an anterior medial and posterior lateral - which extend from the anterior medial tibia to the posterolateral femoral condyle (Griffin). These particular bundle names were given due to their location of insertion into the tibia plateau.
This allows slipping or gliding movements. Saddle: The articular surface of one bone is saddle-shapped and the articular surface of the other is shaped like the legs of a rider sitting in a saddle. This movement is side to side and back and forth as well as circumduction. Pivot: This is a rounded or pointed surface of bone that articulates within a ring formed partly by bone and partly by
