| Question | Answer |
| types of muscle tissue are | skeletal, cardiac, and smooth |
| muscle under strict nervous control; skeletal muscle | voluntary |
| no visible striations; spindle shaped & contain one centrally located nucleus | smooth muscle cells |
| generally multinucleate & are branching cells that fit together tightly at intercalated discs | cardiac muscle cells |
| highly cellular, well-vascularized tissues that are responsible for most types of body movement | muscle tissue |
| specialized connections btwn myocardial cells containing gap junctions & desmosomes | intercalated discs |
| muscle packaged by CT sheets into organs, that are attached to bones & skeleton; form fleshy part of body | skeletal |
| one of the individual filaments of actin or myosin that make up a myofibril | myofilaments |
| muscle whose contractions help propel blood through blood vessels to all parts of body, found only in heart | cardiac |
| appearance, of skeletal muscles, reflects __ __ of their myofilaments | precise alignment |
| located mostly in walls of hollow organs | smooth muscles |
| located in skeletal muscles attached to bones, or occasionally skin | skeletal muscles |
| bring about movement or contraction in all cell types | actin or myosin |
| muscles found in walls of hollow organs (other than heart) that act to squeeze substances through organs by alternately contracting & relaxing | smooth |
| composed of cylindrical multinucleate cells with obvious striations; muscles attached to skeleton; voluntary muscle | skeletal muscles |
| located in walls of heart | cardiac muscles |
| muscle that cannot ordinarily be controlled voluntarily (e.g., smooth & cardiac muscle) | involuntary |
| long, cylindrical cells that contained many nuclei w/obvious banding/straited | skeletal muscle cells |
| skeletal muscles are also called muscle __ | fibers |
