Muscular Tissue Worksheet

Contractile organelles of skeletal muscle; extend the entire length of a muscle fibre
A type of bone which contains few spaces, provides protection & support; resists stresses produced by weight and movement
One of the vitamins required for bone growth
A property of muscle tissue that involves the ability stretch without being damaged; allows muscles to contract forcefully even if it is already stretched
One of the main minerals required for bone growth
This type of muscle tissue has intercalated discs
The process in which there is ongoing replacement of old bone tissue by new ones
A hormone which decreases blood calcium
A hormone which increases blood calcium levels
The synapse between a somatic motor neuron and a skeletal muscle fibre
A property of muscle tissue that involves the ability to contract forcefully when stimulated by an action potential
This type of muscle tissue is striated; involved in movement
Fluid-filled system of sacs that encircles each myofibril; in the relaxed muscle it stores calcium ions; release of calcium triggers muscle contraction
A protein which contains a myosin-binding site where a myosin head can attach
The cytoplasm of the muscle fibre
Unspecialized stem cells
A process in which the thick and thin filaments slide past one another
A type of bone that is mainly located in non-heavily stressed areas or where stresses are applied from many directions
