Musculoskeletal System Research Paper

P4 – Describe the three structures of the skeletal muscle (Epimysium, Perimysium and Endomysium) There are three structures of the skeletal muscle: Epimysium is a thick layer of irregular connective tissue that pulls the entire muscle as well as protecting the muscle from friction that may be caused by other muscles and bones surrounding them. Also, it is the fibrous tissue which covers and surrounds skeletal muscles. The Epimysium carries on past the end of bones in order to create muscle tendons. Perimysium surrounds a bundle of muscle fibres, it is a casing of connective tissue. Endomysium is found within a muscle and it contains nerves and capillaries.

The sponge is light and have low density which balance the heavier parts of bone. Sponge tend to form a long line of stress which gives strength and flexibility in that area (Biology dictionary, n.d). articular cartilage is smooth elastic tissue which decreases friction and distribute load. Cartilage exhibits stress-shielding of the solid matrix components due to its high-water content, the incompressibility of water and the structural organization of the proteoglycan and collagen molecules (Derek Moore,n.d). Epiphyseal line is area of developing tissue and everyone has at least two, one at each end of bonePeriosteum is outer membrane which contains connective tissue, nerves and capillaries.

Function of dermis layer is to provide strength, elasticity and to cushion the body stress and strain. In case of any injury, there are different tissues present in this layer i.e. granulation tissue which are used to heal wounds. It has two layers which are as follows: I. A thick papillary layer II.

Connective tissue varies widely in appearance and function, but all forms share three basic components which are extracellular protein fibers, specialized cells, and a fluid known as ground substance. The combination of the extracellular fiber and ground substances produces the matrix that surrounds the cells. The functions of connective tissue are to establish a structural framework for the body. Secondly, it transport fluids and dissolved materials. The connective tissue also protect delicate organ.

Cartoon Character Skeletal System Project Essay! The human skeletal system consists of 206 bones and associative tissue such as joints, cartilage, ligaments, and tendons. Each bone is a complex living organ that is made up of cells, minerals, and protein fibers. When joined together, the skeletal system provides the base framework, giving shape to the unique human body and provides support and protection for the soft tissues that make up the rest of the body. The skeletal system also provides attachments points for muscles enabling movements at the joints.

The musculo skeletal is made of bones, muscles, ligaments and tendons. The purpose of the musculo skeletal system is to protect , support and the overall function of the internal structures and organs of the body. Allow movement, give shape to the body, producing blood cells, storing calcium and phosphorus and producing heat. The skeletal system is made of bones and joints. The skeletal system provides the basic supporting structure of the body.

Therefore, synovial fluid found in the joint helps minimize friction during extension and flexion of the knee because the viscous fluid functions as a lubricant to act as an absorber to prevent bones from hitting one another. Also, hyaline cartilage helps minimize friction by providing a smooth sliding area that still allows minimum movement of bone without hitting one another. 7. Describe the changes a broken bone undergoes as it is healing. ( 4 points) When bone heals it undergoes four repair phases.

periostitis Inflammation of the disease Periosteum (periosteum) by the dense connective tissue composition, covered in addition to the articular surface outside the bone surface, and many fiber bundles into the bone. In addition, the tendons attached to the bone, the ligaments attached to the periosteum are attached together. So the periosteum and bone binding are very firm. Periosteum is rich in blood vessels, nerves, through the bone of the trophoblast distribution in the bone and bone marrow. Bone marrow and bone cancellous mesh is also lining a layer of meager connective tissue membrane, called endometrial (endosteum), periosteum inner layer and bone endometrial differentiation of osteoblasts and osteoclasts ability to form a new Bone and destruction, transformation has been generated bone, so the occurrence of bone, growth, repair and so on is of great significance.

TASK 3.1 Write a report comparing and contrasting the structure and function of the three types of blood vessels. The Structure and Functions of Blood Vessels ARTERIES The walls of arteries contain smooth muscle fibre that contract and relax under the instructions of the sympathetic nervous system. The functions of the arteries are: transport blood away from the heart and transport oxygenated blood only. Arteries have four different parts, which are; lumen, endothelium, smooth muscle and connective tissue. LUMEN=the lumen of arteries is relatively narrow to maintain high blood pressure.

The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions; support, movement, protection, blood cell production, calcium storage and endocrine regulation that enable us to survive. Below are more details on the exact role the skeletal system has on; protection, shape, support, movement and blood production:

When the bone cells are put together, and they all do their job, they form bone tissue. "Taken together, the bone cells and the extracurricular matrix from the osseous tissue known as bone" (World of Anatomy and Physiology). Bone tissue is very important. The bone tissue forms bones. Bones are a very important in the human system.

Proteins in the blood prevent changes in pH promote coagulation factors, and transport oxygen and carbon dioxide. Proteins also move materials across plasma membranes, and other proteins in the plasma membrane function as receptor molecules. As an energy source, proteins
