All three types.
Skeletal, cardiac and smooth. |
|
|
What kind of cytoplasm do muscle fibers have?
|
Acidophilic cytoplasm.
Contains large amounts of contractile filaments (myofilaments) especially actin (thin filaments) and myosin (thick filaments). |
|
|
Shape and type of muscle cell nuclei?
|
Oval (cigar shapes) euchromatic, oriented longitudinally

|
|
|
Is a muscle cell vascular?
|
HIGHLY
|
|
|
LM appearance of skeletal muscle
|
Large unbranched cylindrical fibers with visible cross-striations in the acidophilic cytoplasm.
Each fiber contains many nuclei (multinucleated) located peripherally ie. underneath the cell membrane (sarcolemma). |
