How many nuclei are present in cardiac muscle fibres?

Explanation

**Step-by-Step Solution:**

1. **Understanding Cardiac Muscle Fibers**: Cardiac muscle fibers are specialized muscle cells found in the heart. They are responsible for the contraction of the heart and are unique in their structure and function.

2. **Identifying the Characteristics of Cardiac Muscles**: Cardiac muscles are striated, which means they have a banded appearance due to the arrangement of actin and myosin filaments. This striation is similar to skeletal muscles.

3. **Determining the Nuclei Count**: Unlike skeletal muscle fibers, which are multinucleated (having multiple nuclei), cardiac muscle fibers are typically uninucleated. This means that each cardiac muscle fiber contains only one nucleus.
