PPT-3.5.3 Skeletal muscles are stimulated to contract by nerves

The sliding filament theory of muscle contraction Gross and microscopic structure of skeletal muscle The ultrastructure of a myofibril The roles of actin myosin calcium ions and ATP in myofibril contraction. 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. Tom Eck – ecktw@umdnj.edu. Major Points. Cranial nerves are tested directly or indirectly on the majority of questions. Know the course of each nerve, especially the foramen each passes through. Know . 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 . 1. Gives shape and support. 2. Protects internal organs. (Skull, Rib-cage). 3. Muscles attach to bones.. 4. Blood cells are formed in bone marrow. . 5. Calcium and Phosphorous storage. . http://kidshealth.org/kid/htbw/SSmovie.html. Learning Objectives:. Describe the functions of the muscular system. Identify structures of the muscular system and the function of each. Describe methods of assessment of the muscular system. Describe disorders of the muscular system. 31 pairs arise from spinal cord. Five groups correspond to regions of spinal cord and vertebrae. Cervical 8 pr.. Thoracic 12 pr.. Lumbar 5 pr.. Sacral 5 pr.. Coccygeal 1 pr.. Structure of a Nerve. 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 Skeletal System . Skeletal System – bones of the body, shields important organs, gives your body shape. Skull protects the brain / Ribs Protect your heart and lungs / Back bone protects your spinal cord. 7 7 in this 0 4960 17 5031 38 5676 87 4133 227 5986 but not but the to that of such as 74 83 and 70 182 021 162 861 53 478 and 5094 and a and n 1 and on a and 100 d 100 d not the 4 and 41 A AAAA 50 10 Department of Morphology and General Pathology.

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.. Lacrymal. gland &Nerves and Vessels in Orbit. Dr S M . Dawar. Husain. . . Assoc. Professor . of . Anatomy.
