Study Notes
Cardiomyocyte Characteristics
- Cardiomyocytes are a type of muscle cell found in the heart.
- The length of a relaxed cardiomyocyte ranges from 50-100 μm.
Cardiomyocyte Structure
- Nuclei are located centrally in a cardiomyocyte.
Function of Intercalated Discs
- Intercalated discs in cardiac muscle cells enable the rapid transmission of electrical impulses and coordinate contraction.
Functional Unit of Cardiomyocytes
- The term used to describe the fusion of multiple cardiomyocytes into a single functional unit is a syncytium.
