Summary[edit]
| Summary | |
|---|---|
| Description | Micrograph of the sinoatrial (SA) node. H&E stain.
The SA node fibre vaguely resemble cardiac myocytes; however, they are thinner, squiggly and stain less intensely (on H&E) than cardiac myocytes. Description of the micrograph - the follow things are seen: Cardiac myocytes of the right atrium are seen at the right/bottom. Nodal artery, a branch of the right coronary artery is seen in the centre - on lumen. Sinoatrial node surrounds the nodal artery and abuts the darker staining cardiac myocytes. Lumen of the right atrium is on the left (endothelial lining not seen). Epicardial apidose tissue is to the right of the SA node. Epicardial space is on the right of the image. Adjacent to nodal tissue is a nerve; the SA node interacts with fibres from the vagus nerve. Related images
