When the bone is finished growing, the hyaline cartilage is turned into osseous tissue. 4. Which kind of bone marrow is in spongy bone tissue? Red bone marrow is located in spongy bone tissue. 5.
3- Describe the [location, composition, and function] of the epiphyseal plate. The epiphyseal plate is located in the metaphysis and is composed of hyaline cartilage. It is the growth plate, it covers the part of the epiphysis where the bone forms an articulation with another bone. It reduces friction and absorbs shock in articular cartilage. 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. Compare and Contrast the microscopic appearance, location and function of spongy and compact bones? a. Long bones consist mostly of compact bone tissue in the diaphysis and have some amounts of spongy bone tissue in the epiphyses. Short, flat, and irregular bones consist mainly of spongy bone tissue, except at the surface, where there is compact bone.
3. Describe the location, composition, and, function of the epiphyseal plate. c. Location- shoulder, hips d. Composition- hyaline cartilage e. Function- bone growth 4. Which kind of bone marrow is in spongy bone tissue? f. Red marrow is the type of bone marrow found in spongy tissue.
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.
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.
Following her recovery, Margaret was placed on three medications: (A) oral calcium supplementation, (B) oral estrogen, and (C) oral alendronate sodium (Fosamax). Specifically describe how each of these medications works to treat Margaret's condition. The oral calcium supplements increase the calcium ions available in her bloodstream, which make it easier for her osteoblasts to use it to build new bone. The oral estrogen will excite the osteoblasts and make them more active, thus taking calcium ions out of the bloodstream and building new bone, as was just discussed. The Fosamax, alendronic Case Study 6 - Bones acid, works by binding very tightly to the bone and preventing the calcium from being removed by the osteoclasts.
-tendons attach muscles to the bones - cartilage protects bones within joints. - synovial fluid: acts as lubricant - synovial membrane: secretes synovial fluid - ligament: joins bone to bone and is strong and flexible - muscle - fibrous capsule: encloses joints - pad of cartilage: gives additional protection - cartilage: absorbs synovial fluid and acts as shock absorber - bone - tendon: joins muscle to bone At a joint there is: Joints and movement continued 2 of 60 1 of 60 How do muscles work? - muscle is made up of bundles of muscle fibres, each fibre is a single muscle cell - each muscle cell is multinucleate (has more than one nucleus) this is because a single nucleus could not effectively control the metabolism of such a long cell. - Tendons connect muscle to bone - the muscle is made up of bundles of muscle fibres. these are bound together by connective tissue.
Assignment 3:Neuroanatomy Project Physiological Psychology | PSY350 A03 Name: Instructor: Date: The CNS or central nervous system is the foundation of our existence. It controls many interact details that make us unique. Such as our personalities, senses, movements, as well as other functions like heart beat, breathing, and blood pressure. The CNS is encased in bone just as the brain is encased in skull and the spinal cord is encased in the vertebral column. The vertebral column is a structure of bone that is located in the back that encases the spinal cord from top to bottom in order to protect it from injury.
Trace mineral are; Iron, Zinc, Iodine, Copper, Manganese, Fluoride, Chromium, and Molybdenum. Major minerals and trace minerals helps the body in carrying out important bodily functions. For example Magnesium and calcium both aid the body in building strong bones and teeth. Potassium Keeps fluids balanced in blood and tissue. Iron is essential for producing red blood cells and transporting life giving oxygen to the organs of the body.
