Cardiac Muscle (Product Code: SCL438/0165) is a prepared microscope slide of heart muscle used to teach the branched, striated tissue that forms the wall of the heart in biology, zoology and physiology practicals. Students use it to find intercalated discs and centrally placed nuclei, the features that separate cardiac muscle from skeletal and smooth muscle. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, on clear borosilicate glass in a white plastic box.

Cardiac muscle combines features of the other two muscle types: like skeletal muscle it is striated, and like smooth muscle it is involuntary and has centrally placed nuclei. What sets it apart is that its fibres branch and join end to end at dark, step-like intercalated discs. On this slide students locate the branching network, the central nuclei and the discs, and teachers use those structures to explain how an electrical impulse spreads quickly so the heart contracts as one unit.
Used with the smooth and striated muscle slides, it completes one of the most common comparison exercises among biology teaching aids for animal tissues. The cross-striations are fainter than in skeletal muscle, so use the high-power objective with reduced condenser light and scan until a clear intercalated disc comes into view. Store the slide in its plastic box between sessions.

How is cardiac muscle distinguished from skeletal muscle on a slide?
On the Cardiac Muscle slide, the fibres branch and join at dark, step-like intercalated discs, and each cell has a centrally placed nucleus. Skeletal muscle fibres, by contrast, are unbranched, much longer and carry many nuclei pushed to the edge.
What are intercalated discs?
Intercalated discs, visible on the Cardiac Muscle slide as dark cross-lines, are specialised junctions where neighbouring heart muscle cells meet. They hold the cells together and let electrical signals pass directly from cell to cell, so the heart contracts as one unit.
Why does heart muscle not tire like skeletal muscle?
The tissue on the Cardiac Muscle slide resists fatigue because heart muscle has a rich blood supply and many mitochondria. It keeps respiring aerobically between beats, so it can go on contracting rhythmically throughout life without building up fatigue.
From which animal is the tissue taken?
The source animal for the Cardiac Muscle slide is not specified in its product information. Contact us before ordering if your laboratory records or syllabus require a named species, and we will confirm it for you in the quotation.
