Name the three proteins present on the thin myo-filament

Explanation

To answer the question about the three proteins present on the thin myofilament, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Myofilaments**: Recognize that myofilaments are the structural components of muscle fibers, specifically in skeletal muscle, which is responsible for voluntary movements.

2. **Identifying Thin Myofilaments**: Focus on the thin myofilaments, which are primarily composed of the protein actin. This is crucial as the question specifically asks about the proteins within the thin filament.
