Our bodies use carbs in the form of glucose for our brain to gain energy to function correctly. The carbohydrates that the brain does not use, is stored as reserve energy. Carbohydrates are very important as not only do they give energy to the brain, but carbs are also a source of calories to help maintain body weight. 3. Fats.
The skeletal system consists of 206 bones and has other body attachments that assist in connecting them which are tendons, ligaments, and cartilage. The skeletal system provides vital functions for the human body. The functions this system provides are support, movement, protection, blood cell production, storage for calcium and endocrine regulation. Bone serves as the basic unit of the human skeletal system. Ossification is characterized as a process that produces new bone.
For this reason, the muscle contractions are part of every person’s movement of a certain body part. Because of this, the muscle contractions are formed fibers packed within each other to form a rod like myofibrils that contain two types of protein filaments. Also, both of these protein filaments (myosin and actin) help contract the muscle fibers. In consideration of this, when the muscle receives nerve impulses, the protein filaments contract thus making the muscle contract within the body. Furthmore, muscle mechanics play a part in this system.
The muscular system is a very important part of the human body. It has many components and functions, and is the source of the body’s movement. There are roughly 650 muscles in the human body and are different types of muscles. Muscles can either be voluntary or involuntary which means controlled or uncontrolled movement. Muscles have many reasons and in this paper you will widen your knowledge of muscles and their functions as well their diseases and how they help maintain the body.
It provides protection for such vital organs as the brain, heart and lungs, the marrow of bone produces new blood cells, and it aids the body in balancing acid and electrolytes. Bone is a connective tissue with a hardened matrix that is developed from calcium phosphate deposits. Calcification is the process that creates the hard tissue of bones. They come in various shapes and sizes, from flat bones
The axial skeleton consists of the skull, hyoid bone, vertebral column, sternum and ribs. The axial skeleton is a vital part of the skeletal structure e.g. bones as it protects the CNS (central nervous system); it also provides attachment of other bones and muscles in the body e.g. arms and legs The Appendicular Skeletal This consists mainly of bones from the upper and lower parts of the limbs. The bones of the upper part are the humerus bone, the fore arm bones, hand bones and this is connected to the shoulder bones.
This is accomplished through systemic circulation and pulmonary circulation. In systemic circulation, the heart pumps blood through the extremities and most of the organs of the body. Through pulmonary circulation, the heart pumps blood through the lungs. It takes the de-oxygenated blood away from the heart, to the lungs, and back to the heart with oxygen-rich blood. Because the heart is an intricate organ it has many parts that can fail due to disease or dysfunction.
4. Vitamin D: Vitamin D promotes the absorption of calcium in the body, which is important for bone health and development as you grow. It also helps reduce inflammation and benefits your immune system. It is needed for proper absorption of calcium; stored in
Cartilage is tissue, cartilage is found where the body needs a little more flex than in more places (interactive-biology.com). Ligaments in the body are found where joints are, actually joints are made up of many ligaments. The two systems work with the other systems to provide support and allow movement throughout the body, the systems work together by having the nervous system send signals to skeletal muscles in the body, which then contract to produce movement. In bone marrow blood cells are made due to hemocytoblasts and with the right elements creates
John Centore2 Dr. Jain Anatomy & Physiology The many nuclei of skeletal muscle fiber are located underneath the sarcolemma, which is the fiber’s plasma membrane. Thousands of invaginations of the sarcolemma, which are called T Tubules, Tunnel from the surface to the center of the muscle fiber. These T Tubules are open to the outside of the fiber and are filled with extra-cellular fluid. Muscle action potentials propagate along the sarcolemma and through the T tubules and quickly spread through the muscle fiber. This process ensures that all parts of the muscle fiber become excited by an action potential virtually simultaneously.
