How do skeletal and cardiac muscles differ?

Answer 1

cardiac is uni/binucleate, has intercalated discs, and is has branching fibers, skeletal is multinucleate and is long and cylindrically shaped.
Skeletal muscle is found in the arms and legs and also other parts of your body. For skeletal muscle to contract it needs to be independly stimulated by a nerve ending. Cardiac muscle is a involantry muscle within the heart which automaticly contracts because of its self- excitable cells. It is a muscle which does NOT produce lactic acide ( normally) and it does not need a nerve to stimulate it to contract

Answer 2

Cardiac muscles contain intercalated discs (thick straight lines between muscle cells), Perkinje fibres (thicker, glycogen filled cells), and the muscle cells branch and generally contain a large central nucleus.

Skeletal muscle cells never branch, they contain nuclei on the periphery (and often each cell has multiple nuclei) and do not contain intercalated discs or Perkinje fibres.

Answer 3

Skeletal muscles are attached to bones and responsible for voluntary movements, while cardiac muscles are found in the heart and responsible for involuntary contractions to pump blood. Skeletal muscles have multiple nuclei per cell and can be consciously controlled, while cardiac muscles have a single nucleus per cell and contract rhythmically without conscious effort.

Answer 4

don't be lazy like I am lol. open your science book, read it, learn it..............love it.

Answer 5

cardiac muscle is involuntary muscle, while skeletal muscle is voluntary.

Answer 6

Skeletal muscles are striated muscles that perform voluntary functions. Cardiac muscles are smooth and perform involuntary functions.

Answer 7

cardiac muscle cells are different they are called pacemaker cells the body cannot reproduce these cells once they die that's it.

Answer 8

Cardiac muscle is involuntarily controlled, like smooth muscle.

Cardiac muscle is also striated (has repeating sarcomeres), like skeletal muscle.
