Skeletal Muscle Tissue
Voluntary muscle attached to the skeleton, featuring striations and multinucleated, long cylindrical cells. Cardiac Muscle Tissue
Involuntary muscle found in the heart, with striated, branching, uninucleate cells connected by intercalated discs. Smooth Muscle Tissue
Involuntary muscle in walls of hollow organs, lacking striations, with short, spindle-shaped, uninucleate cells. Striations
Banded appearance in muscle tissue due to alignment of protein myofilaments, present in skeletal and cardiac muscles. Voluntary Muscle
Muscle type under conscious control, allowing for deliberate movements, exemplified by skeletal muscle. Involuntary Muscle
Muscle type not under conscious control, including cardiac and smooth muscles. Multinucleated
Cells containing multiple nuclei, characteristic of skeletal muscle fibers to meet high protein demands. Uninucleate
Cells with a single nucleus, typical of cardiac and smooth muscle cells. Cardiomyocytes
Heart muscle cells that are striated, branching, and usually uninucleate, forming cardiac muscle tissue. Intercalated Discs
Structures connecting cardiomyocytes, enabling coordinated contractions in cardiac muscle tissue. Spindle-shaped Cells
Cells that are narrow at the ends and thicker in the middle, characteristic of smooth muscle tissue. Protein Myofilaments
Protein structures in muscle cells responsible for contraction, aligned to form striations in some muscle types. Tendons
Connective tissues that attach skeletal muscles to bones, facilitating movement. Biceps
Example of skeletal muscle that can be voluntarily controlled, located in the upper arm. Digestive System
System containing smooth muscle tissue in the intestines, aiding in propulsion of food.
