Muscular System Amarilis Ramos Period 2
3 type of Muscle tissues and their major function
Cardiac Muscle
Function is to contract the heart to pump blood
Smooth Muscle
Function is to store calcium ions inside the cell to be able to help women
Skeletal Muscle
Function is to Support and protect and provide calcium storage for the body
Major function of muscular system
Main function of the muscular system is to produce movement stabilize joints ,generate heart,and to help maintain posture and body position
Body movement terminology
Rotation
Abduction
Extension
Flexion
Circumduction
Location/actions
Arm
Brachialls
Bicep Brachial
Upper Body
Zygomatic
Deltoid
Lower Body
Sartorios
Fibulas Longus
Organization Levels of skeletal muscle
Muscle Fibers(cells)
Myofibrils
Fascicles
Thick and thin Filament
Muscle
Name of Muscle
Contractility
ability to shorten forcibility when stimulate
Elasticity
muscles that recoil its resting length
Excitability
ability for cells to receive stimulus change
Physiology of muscle contraction (filament theory)
Relaxed
Sarcomere are apart and unbid and uncoil
Contracted
Sarcomere are shortening when contracted
The goal of filament theory is the way muscles contact to produce force
disorder associate with Muscular system
Spasm
twitch in smooth ,skeletal muscle that can cause a lot of pain
Torticollis
neck stays rotated to one side and head stays rotated
Fibryomychlgia
when there is an inflammation of muscles
Hernia
protrusion of organ in a body cavity that is usually caused when lifting heaving weights
