Musculoskeletal System The human musculoskeletal system is the organ system that gives humans the ability to physically move‚ by using the muscles and skeletal system. It consists of the muscular system and the human skeleton. Bones are connected to each other at the joints by ligaments or cartilage and skeletal muscle is attached to bones‚ usually by tendons. Bones mass or density is lost as people age‚ especially in women after menopause. The bone loses calcium and other minerals. Bone is a constantly

d 4.4 The Fisherman – Part 1 A fisherman is standing on the edge of a cliff overlooking a flowing river. The edge of the cliff is 8 feet above the level of the water. The tip of his fishing rod is directly above the edge of the cliff and is 7 feet above the cliff. He lowers his fishing line so that it enters the water at the base of the cliff. The length of his fishing line‚ l‚ which is measured from the tip of his fishing rod to the place his line enters the water‚ and the angle between his

+Amendments for D2: Skeletal muscles allows for many different types of muscle contractions such as eccentric‚ concentric‚ isometric and isokinetic. These muscles are voluntary and the contractions produced have a huge impact on Wilkinson’s game. For example when he is striking a ball his quadricep contracts concentrically to produce force onto the ball. The more powerful the muscle the bigger the contraction‚ therefore if Johnny improves the strength of his quadriceps his kicking distance could

Module 04 Case Study: Bone Tissue Part I— “Marissa” Questions 1. Describe bone tissue and the role each component plays in bone physiology and remodeling. What is the difference between compact and spongy bone? (2 points) Spongy bone looks like a sponge hence the name and contains a lot of red bone marrow (medulla ossium rubra). Red bone marrow is what produces red blood cells. Compact bones which consists of medulla ossium flava or yellow bone marrow‚ is made mostly of fat cells (Openstax College

WTHESIS STATEMENT: “BIOCONVERSION OF WATER HYACINTH (EICHHORNIA CRASSIPES) TO ETHANOL.” 1. INTRODUCTION Water hyacinth (Eichhornia crassipes) is a free-floating or rooted in mud plant or weed which can totally cover fresh water lakes‚ harbors‚ and other essentially relatively occluded fresh water bodies. It is a fast growing permanent aquatic plant that are extensively scattered all throughout the world. This tropical plant can be the reason for the infestation over large areas of water resources

What is the difference between compact and spongy bone? (2 points) Bone tissue is composed of bone cells and extracellular matrix. It is continuously remodeling its extracellular matrix according to the stresses placed upon it. It has a lot of blood flow and it is supplied by the nervous system. The bone cells includes; Osteocytes‚ osteoblasts
