skeletal muscle
Skeletal muscle tissue is packaged by connective tissue sheets into organs called skeletal muscles that are attached to the bones of the skeleton. These muscles form the flesh of the body, and as they contract they pull on bones or skin, causing body movements. Skeletal muscle cells, also called MUSCLE FIBERS, are long, cylindrical cells that contain many peripherally located nuclei. Their obvious banded, or striated, appearance reflects the precise alignment of their myofilaments. |

cardiac muscle
Description: branching, striated, generally uninucleate cells that interdigitate at specialized junctions (intercalated discs) Function: As it contracts, it propels blood into the circulation; involuntary control Location: the walls of the heart |

Cardiac Muscle
Cardiac muscle is found only in the walls of the heart. Its contractions help propel blood through the blood vessels to all parts of the body. Like skeletal muscle cells, cardiac muscle cells are of the body. Like skeletal muscle cells, cardiac muscle cells are striated. However, cardiac cells differ structurally in that they are - generally uninucleate (one nucleus) with the nucleus situated centrally - branching cells that fit together tightly at unique junctions called INTERCALATED DISCS. |
