Composed of cells that are highly specialized to shorten in length by contractility.. Made up of cells that are called . myocytes. .. Elongated in one direction (muscle . fibres. Muscular . System Functions:. Muscle Tissue Can Contract (shorten) and Relax (lengthen). This causes mobility and provides support.. Allow for movement of:. skeleton – muscles are connected to bones. Muscle Tissue Characteristics. Contractile. Made of contractile proteins. Cells are called fibers. Skeletal Muscle. 40% of body weight. Under voluntary control; attached to skeleton. Striated, or banded, appear. Chapter 8. Muscle Spasm and Spasticity. Spasticity is a central nervous system dysfunction . Spasticity is technically not a disease process but a result of motor interruption (lesion), typically in the upper motor complex of the central nervous system. The heart is odd one out. The heart is made from cardiac muscle. The bicep muscle (in the arm), the calf muscles ( in the legs) and the diaphragm (in the chest) are types of skeletal muscles.. Investigating muscle strength . As it contracts it . -causes movement. -maintains posture. -stabilizes joints. -and generates heat. . Muscle Types. Skeletal muscle (voluntary). muscle attached to the skeleton. cells are long, striated, and multinucleate. Objectives. Histologically identify and functionally characterize each of the 3 types of muscle tissues.. Describe the organization of the sarcomere as seen in light and electron microscopy.. Identify the .

Sabrina Barner, Abbe Carlin, Amber Weigle. Neuromuscular Junctions. Communication link between nervous system and skeletal muscle fiber. Specialized intercellular connection. Each skeletal muscle fiber is controlled by a nerve cell. The tongue is the strongest muscle in the body (relative to size). There are about 640 skeletal muscles in the human body. It takes twice as long to lose new muscle if you stop working out than it did to gain it.. . Human Skeletal System. Functions. Framework and support. Protection. Storage of minerals such as calcium. Movement. Production of blood cells (bone marrow). Human Skeletal System. The . axial. skeleton is the central part of the skeleton used to protect vital organs such as the brain, heart, and lungs..
