Cardiac muscle

Cardiac muscle.

• Note that fibers branch and interconnect.
• Fibers consist of individual cells attached end-to-end.
• Nuclei (one per cell) are centrally located within each cell.
• Intercalated discs are sites of attachment between cells.
• Striations may or may not be conspicuous (not here), depending on stain and plane of section.
