- Q1One of the three types of muscles. Muscles move voluntarily and are attached by tendons to bones. They are long, multinucleate (have multiple nucleus), appear striated (due to arrangement of actin and myacin), and are surrounded and bundled by connective tissue. (which supplies nutrients)Skeletal Muscle30s
- Q2A connective tissue wrapping which wraps itself around a single muscle cell/fiber.Endomysium30s
- Q3A connective tissue wrapping which wraps itself around a fascicle (bundle) of cells/fibers.Perimysium30s
- Q4A connective tissue wrapping which covers the entire skeletal muscle.Epimysium30s
- Q5Is a cord like structure which connects muscles to bones. It is formed by epimysium blending into connective tissue attachments.Tendon30s
- Q6One of the three different types of muscle tissue. This muscle has no striations and is formed from spindle shaped cells, they possess a single nucleus, move involuntarily, and are found mainly in the walls of hollow organs.Smooth Muscle30s
- Q7One of the three types of muscle tissues. These have striations, usually a single nucleus, are joined together by another muscle cell by an intercalated disc, function involuntarily, and are found only in the heart.Cardiac Muscle30s
- Q8The cell plasma membrane of a striated muscle cell.Sarcolemma30s
- Q9The contractile unit of a myofibril consisting of Z-discs, A-bands, and I-bands.Sarcomere30s
- Q10A unit of stored energy which muscles use initially for contraction. Only 4-6 seconds of ATP energy is stored by muscles. The bonds within ATP are broken in order to release the energy.ATP30s
- Q11A metabolic process requiring oxygen and taking place in the mitochondria. Glucose and fat are broken down to carbon dioxide and water in order to release energy.Aerobic Respiration30s
- Q12A metabolic process that doesn't require oxygen. Glucose is broken down to pyruvic acid to produce some ATP. Pyruvic acid is then converted to lactic acid.Anaerobic Respiration30s
- Q13Movement in the saggital plane that decreases the angle of the joint and brings two bones closer together.Flexion30s
- Q14Opposite of flexion; movement in the saggital plane that increases the angle of the joint or distance between two bones or parts of the body.Extension30s
- Q15Movement of a bone around its longitudinal axis.Rotation30s
