Across
  1. 2. a bundle of skeletal muscle fibers;
  2. 6. also known as a myofiber, single multinucleated cells surrounded
  3. 7. a connective middle-layer tissue that wraps around a bundle of skeletal muscle cells (myofibers)
  4. 8. the membrane of each muscle fiber (or muscle cell)
Down
  1. 1. contractile fibers within muscle fibers, composed of cytoskeletal proteins called mofilaments (actin & myosin)
  2. 3. loose connective tissue that envelopes each muscle fiber, and connects adjacent muscle fibers together, within each fascicle.
  3. 4. the outermost fibrous tissue layer that is thick, dense, and encloses muscle groups.
  4. 5. sheath of dense, irregular connective tissue that wraps each skeletal muscle; allows a muscle to contract and move powerfully while maintaining structural integrity.
