Appears homogeneously bright red.
|General Microscopic Description|
Myocardial fibers are striated and are made up of
individual cellular units containing one or two
centrally placed large ovoid nuclei.
Elongate units are either unbranched and separated
at each end from adjoining units by intercalated discs,
or may branch, with intercalated discs demarcating
the branch ends from adjoining branched or unbranched
cellular units. This is not a true syncytium.
Yellow lipofuscin granules accumulate with increasing
age near the two poles of the nucleus.
