(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. It endures forces acting starting on the outer surface of the knee which is called valgus forces, this stops the knee from collapsing inwards. The MCL has two parts; an inner part that
In a more detailed way, the hamstrings cross and act upon two joints, the hip and knee (--------------). The Semitendinosus and the Semimembranosus extend the hip when the trunk is fixed. The two muscles also bend the knee and rotate the lower leg when the knee is bent. As for the Bicep Femoris, a good example to explain its function is when an individual is walking. The long head of the bicep femoris ends the hip as we begin to walk.
Which type of bone provides a large, flat surface for muscle to attachment? b. A flat bone provides a large surface for muscle to attach. For example the hip bone and rib bones. 3.
Flat bones are generally thin and provides extensive surfaces for muscles attachment. Flat bones: scapula, cranial , the sternum and the ribs 3. Describe the location, composition, and function of the epiphyseal plate. Epiphyseal plate is located in the metaphysis and is composed of the hyaline cartilage and its function allows for bones to grow in length. 4.
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.
Shanakay Campbell 10/30/2014 A&P2530 Hassan’s Story A. Which clue would tell Stefan which scapular surface was anterior and which was posterior? What is the name of the shallow, oval socket of the scapula that Stefan placed next to the humerus? A: The scapula is a large triangular, flat bone situated in the superior part of the posterior thorax. A prominent ridge called the spine runs diagonally across the posterior surface of the scapula.
5. Which ossification method would form a femur? The femur, which is a long bone, is formed by endochondral ossification which is the replacement of cartilage by osseous tissue. Most bones of the body are formed by this process. 6.
Essay shows the importance of bones in human body and their main role, tasks they accomplish every day. Skeletal function Six functions of the skeleton: Support: Provides structural support for the entire body Protection: Surrounds soft tissue- ex. ribs and sternum protect the heart and lungs, - skull protects the brain Movement: Skeletal muscle is attached to bone so it pulls on the bone when it contracts Mineral homeostasis: Stores calcium and phosphorus--minerals are released into the blood when needed Blood cell production: Red bone marrow produces red blood cells, white blood cells and other blood elements. Storage: Storage of minerals and lipids (fats)-yellow marrow stores fat-(found in long bones) Bone. Definition: Bones are rigid organs that constitute part of the endoskeleton of vertebrates.
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.
The rearfoot consists of four bones the distal side of the tibia and fibula (leg bones), the calcaneus (heel bone), and the talus. The plantar fascia originates from the medial calcaneal ligaments, dividing into a medial, central and lateral band that attaches to the superior surface of the abductor hallucis, flexor digitorum brevis, and abductor digiti minimi musculature, respectively. The medial longitudinal arch (MLA) of the foot aids in distributing the force attributed to the weight bearing. The MLA of the foot resembles two rods a rear rod consisting of the calcaneus, talus and an anterior rod consisting of the navicular, three cuneiforms, and the first three metatarsals. These rods are connected at their base by the plantar fascia.
