Muscle Types
The three main types of muscle tissue
What are Skeletal, Cardiac, and Smooth?
Connective tissue sheath that encloses each muscle fiber
What is the endomysium?
The primary function of all muscle types
What is "to produce movement"?
The name for the plasma membrane of a muscle cell
What is sacrolemma?
The special property of a muscle cell that gives it the ability to receive and respond to a stimulus
What is excitability?
Muscle tissue types that are categorized as involuntary
What are cardiac and smooth?
What is the perimysium?
Other functions that are related specifically to skeletal muscle
What is maintain posture, stabilize joints, and generate heat?
The long ribbon-like organelles in the cytoplasm of a muscle cell
What are myofibrils?
The ability of a muscle to shorten when adequately stimulated
What is contractility?
Muscle cells that are striated in appearance
What is a fascicle?
Besides anchoring muscle to the bone, tendons also serve in these two ways
What is "provide durability" and "conserve space"?
The two myofilaments that produce the banding pattern on a muscle cell
What are actin (thinner) and myosin (thicker)?
The ability of a muscle to be stretched or lengthened
What is extensibility?
The most common of the types of muscle tissue
What is skeletal muscle?
The connective tissue "overcoat" that covers the entire muscle
The way in which cardiac tissue produces movement
What is "pumps blood to all the tissues of the body"?
The tiny contractile units of a myofibril
What are sarcomeres?
The ability of a muscle to return to its original shape (recoil)
What is elasticity?
What is smooth muscle?
The name of the structure that attaches muscle to bonen
What is a tendon?
The role of the sarcoplasmic reticulum in the muscle cell
What is "to store calcium and release it when the cell is stimulated to contract"?
The border of each sarcomere that is formed by the alternating thin filaments in a zig-zag pattern
What is the Z-line?
When extension exceeds 180 degrees
What is hyperextension?
