Unit 232 Move and position individuals in accordance with their plan of care 1. Understand the anatomy and physiology in relation to moving and positioning individuals 1.1 Outline the anatomy and physiology of the human body in relation to the importance of correct moving and positioning of individuals Joints enable your body to move. They are the place where two bones meet. There are several different types of joints. The ball and socket joints are the most mobile type of joint in your body.
It plays the most important role in the extensor mechanism of the knee joint (3). The quadriceps tendons and patellar tendons link up with patella to serve the function. Extension of knee can be achieved by the tension between quadriceps and patella. Flexion of knee is limited by the quadriceps tendon. As a whole structure, patella becomes a pulley to generate force between patella-femoral joint in order to support the body against gravity
This writer will present research on the common mechanisms of injury, the sports they are most common in, the recovery and rehabilitation involved, as well the incidence rates of injury. Anterior Cruciate Ligament Anatomy The femur and the tibia are bones that make up the knee and at the attachment they form a hinge joint. This joint is protected in the front by the patella and cushioned by articular cartilage which shields the base of the patella and the ends of the femur and tibia. Cartilage that further promotes the protection of the knee is the lateral and the medial meniscus. These act as a type of shock absorber between the bones.
1. Why osseous tissue is considered a connective tissue? a. Osseous tissue is considered connective tissue because just like connective tissues, osseous tissue contains an abundant extracellular matrix that surrounds widely separated cells. 2. What is the path a nutrient would travel through compact bone tissue from its diffusion out of a blood vessel in the periosteum to an osteocyte located within the second osteon in from the surface of the bone?
The knee is the largest synovial joint (the most common and moveable type of joint) in the human body. It allows extension and flexion as well as slight medial and lateral rotation when the knee is flexed. The knee is also the most injured joint in the body as it is responsible for most of the weight bearing of the body. When we walk, our knees support 1.5 times our body weight; climbing stairs is about 3-4 times our body weight and squatting about 8 times. The knee is also responsible for providing flexibility that allows movement like walking, running, and climbing.
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.
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 of the long bone body are formed by this process. 6. Why is bone remodeling necessary when a person reaches adulthood?
j. The vomer bone forms the inferior part of the nasal 9. How many bones make up the upper limb? k. 30 bones make up the upper limb 10. Which part or parts of the femur articulate with the acetabulum at the hip joint?
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.
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.
