contrast the makeup of cardiac and skeletal muscle. Skeletal muscle consists of long, cylindrical cells called muscle fibers and each cell consists of multiple nuclei. It appears striated and this is due to overlapping of proteins that are involved in the contractile process. Skeletal muscle is voluntary. Cardiac muscle is located in the heart and it may also be found in nearby large vessels. It is also striated like skeletal muscle and cells are much shorter than skeletal muscle cells. Cells are called
The hand is a very important extremity attached to the human body and is used in everyday life. Humans use it doing almost everything. The major systems the body uses to be able to move the hands are the skeletal, muscular and nerves systems. The skeletal system of the hand involves the bones, such as, eight carpal bones, five metacarpal and fourteen finger bones (Istitute for Quality & Efficiency in Health Care, 2013). All connected by joints and ligaments. The muscles include two parts, the thenar
rickets. Adding vitamin D or calcium to the diet will generally correct the bone problems associated with rickets. Rickets should not be a single minded focus regarding a child’s diagnosis, but other underlying medical treatment would be needed. Some skeletal deformities caused by rickets may require corrective surgery.” The symptom
This opposite and complementary activity between these two lineages of cells maintains the homeostasis of bone resorption and formation during bone remodeling. Dysregulation of this process is a major mechanism in the pathogenesis of many human skeletal disorders such as osteoporosis and osteochondroma (Edwards, 2012). Osteoporosis is one of the major contributors to the overall physical and psychological manifestations of frailty associated with aging. Osteoporosis-related fractures are a common
your bodies systems which make your body function properly. A body system is a group of organs that work together to carry out a particular task. The skeletal system is all of the bones in your body. The skeletal system provides support for the body, protects the internal organs, and it works as a supportive framework for muscles and enables limbs and digits to move. Another system is the muscular system which is all the muscles in your body. The muscles we see and feel are skeletal muscles. You

Keywords Liquid skeleton Exoskeleton Endoskeleton moulting Notes Skeletons are used for: Supporting that body Protecting the body Moving the body When an animal sheds and exoskeleton and grows a new one because of its size it is called moulting. Metamorphosis is the change in body form as an animal grows. The dramatic change from young to adult is called complete metamorphosis. Summary Bones - Bones provide the structure for our bodies. The adult human
joint and the way it helps to support, stabilise, strengthen and create movement. Areas that will be explored are the skeletal system, different types of joints and all the tissues involved at the hip joint. The skeletal system has five main functions which consist of support, movement, protection of organs, blood cell production and mineral release and storage. The skeletal system is made up of two parts, the Axial skeleton and the Appendicular skeleton. The Axial skeleton includes of the skull
growth, as well as maintaining healthy bones, is dependent upon several hormones produced in the body. The hormone Calcitriol, which is produced in the kidneys, plays a key role in the absorption of calcium and phosphate ions within the digestive system. The pituitary gland is responsible for the Growth hormone. It causes the building up of the bones, producing bone growth. The development of the hormone Thyroxine comes from the thyroid gland. Thyroxine prompts the cells metabolism and it increases
tissue and an inner osteogenic layer. The periosteum protects and repairs the bone while also enabling tendons and ligaments to form an attachment with the underlying bone. (Tortora and Derrickson, 2011). 1.2 Explain the functions of bone The skeletal system has 6 main functions and makes up 18% of the overall weight of the human body. (Tortora and Derrickson, 2011)
The skeletal system is made up of 206 bones that protect our internal organs. Bones are hollow and contain bone marrow. Bone marrow is a spongy red tissue that produces red blood cells. There are various diseases and disorders that affect the bone. One is bone cancer or bone neoplasm. Bone cancer is a cancerous tumor of the bone that destroys the standard bone tissues. This disease can originate in any bone of the body. This cancer can also begin in an organ and spread to the bone. Usually, it affects
