The primary roles of muscles include movement, stabilization, substance transport, and heat generation.

The ability of muscular tissue to generate electrical signals in response to stimuli, known as action potentials.

The muscular tissue's capability to contract forcefully when stimulated by an action potential.

The ability of muscular tissue to stretch without being damaged, within certain limits.

The property of muscular tissue to return to its original length and shape after being stretched or contracted.

Tissue composed of elongated cells (muscle fibers) that contract to produce force.

The three types are skeletal, cardiac, and smooth muscle, each with distinct functions and structures.

Striated muscle attached to bones for voluntary movement; made of long fibers.

Striated muscle found in the heart, involuntary, responsible for pumping blood.

Involuntary muscle found in walls of organs; not striated, controls automatic movements.

Connective tissues that attach muscles to bones, aiding in movement.

Broad, flat connective tissue sheets attaching muscles to each other or to bones.

Skeletal muscle fibers consist of myofibrils, which contain myofilaments (actin and myosin).

Proteins that maintain the alignment of filaments and provide elasticity to myofibrils.

A structural protein that helps maintain the elasticity and alignment of thick filaments in muscles.

Proteins responsible for generating force during muscle contractions, primarily myosin and actin.

A thick filament contractile protein that forms the main component of muscle fibers and has a tail and two heads.

A contractile protein that is the primary component of thin filaments, has a binding site for myosin heads.

A multinucleated cell with striated bands, attached to bones.

Muscle with alternating light and dark protein bands, primarily skeletal muscle.

Thickened regions in cardiac muscle that connect cells and allow rapid communication.

Characteristic of cardiac muscle to initiate its own contractions without nerve signals.

Muscle control not consciously directed, includes cardiac and smooth muscle.

Calcium ions are stored in relaxed muscles, essential for contraction.

Release of calcium ions triggers muscle contraction during movement.

Extensive network that carries electrical signals into muscle cells.

A triad consists of one T-tubule and two terminal cisternae.

The functional unit of skeletal muscle, composed of thick and thin filaments.

Proteins such as troponin and tropomyosin that regulate muscle contraction.

Myofibrils are built from contractile and regulatory proteins important for muscle function.

Powerful, involuntary contractions for motion, controlled by endocrine and autonomic system.

The outermost connective tissue layer encircling the entire muscle, made of dense irregular tissue.

Dense connective tissue surrounding groups of muscle fibers, forming bundles called fascicles.

A delicate tissue layer with reticular fibers, separating individual muscle fibers within a fascicle.

Bundles of muscle fibers grouped by perimysium, can contain 10-100 or more fibers.

A specific tendon (Achilles) connecting the gastrocnemius muscle to the heel bone.

Layers of tissue (epimysium, perimysium, endomysium) that organize muscle structure.
