The musculoskeletal system is a complex arrangement of bones, muscles, cartilage, tendons, ligaments, joints, and other connective tissue. This system provides form, support, stability, and movement for the body. It is comprised of two separate systems, the skeletal system and the muscular system. Both of these systems are vital for the body to be able to function properly. For instance, the skeletal system protects and supports the weight of the body’s organs, serves as storage for calcium and phosphorous, and contains critical components for the production of blood.
The skeletal system provides the basic supporting structure of the body. It is made of the joined frame of bones called the skeleton. The human skeleton in a whole is made up of 206 bones in total. Bone in the human body is a dry, dense tissue. Bone is made of a calcium-phosphorus mineral, organic matter and also water.
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:
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. It allows blood in and out of bone and help with growth and repair (PubMedhealth,n.d). compact bone provides the strength and protection of bones. It provides strong mechanical layers which with
Third, hard callus forms when osteoblasts produce trabeculae and the callus is replaced by this bone. Bone will continue to grow and thicken. Finally, remodeling is the final phase of fracture repair. During the final phase osteoclasts remove excess bony material from both exterior and interior surfaces. Compact bone is now replaced by primary bone.
Stratum Lucidum III. Stratum Granulosum IV. Stratum Spinosum V. Stratum Basale 1.2.2. Dermis It is middle layer which contain connective tissue, sweat gland, hair follicles, collagen, blood vessels, nerves and various glands. Function of dermis layer is to provide strength, elasticity and to cushion the body stress and strain.
Explain how cells are important to tissues. Cells are important because cells are formed to make tissue. Another reason is cells in a tissue work together to do a specific job. 4. Synthesize how might the digestive system and the circulatory system work together?
LUMEN=the lumen of arteries is relatively narrow to maintain high blood pressure. ENDOTHELIUM=forms the inner layer of an artery wall, also known as the tunica interna. It consists mainly of endothelial cells. SMOOTH MUSCLE= smooth muscle and elastic tissues
The membrane is selectively permeable which certain molecules are allowed to enter and exit the cell. The transport of molecules that enter and exit out of the cell require an endomembrane system that separates and compartmentalizes the different cellular functions of a variety of organelles. In Cell Structures Involved in
Peristalsis is a natural process of area contraction and expansion along the length of the tube/channel. The peristaltic flows of Newtonian and non-Newtonian fluids have immense applications in physiology and industry. In physiology, many body parts such as stomach, gastrointestinal tract and small intestines are the common examples in which peristaltic waves appear. The peristaltic phenomenon has great importance in the movement of food bolus in the digestive system, chyme motion in the gastrointestinal tract, transport of lymph in the lymphatic vessels, movement of ovum in the fallopian tube, passing of bile from gall bladder to duodenum, urine flow from kidneys to bladder, etc. This mechanism is also involved in plant physiology which is
The osteoprogenitor, also known as the precursors, Become osteoblast and osteocytes and help the cells reproduce. They do not have a known main function for the cell other than just becoming the other bone cells, which is important. They look very similar to osteocytes with more of the lines coming off and a thinner oval shaped main part of the cell, or head. Each bone cell has a very important job in the human body. When the bone cells are put together, and they all do their job, they form bone tissue.
