Which accessory proteins are present along with actins in the muscles?

Explanation

### Step-by-Step Solution:

1. **Identify the Main Contractile Proteins**: In muscle tissue, the primary contractile proteins are actin and myosin. Actin is known as the thin filament, while myosin is the thick filament.

2. **Understand the Structure of Actin**: Actin filaments, also known as F-actin, are composed of two helical strands of globular actin (G-actin) monomers. This structure is crucial for muscle contraction.

3. **Recognize Accessory Proteins**: In addition to actin, there are accessory proteins that play a regulatory role in muscle contraction. The two main accessory proteins associated with actin in muscles are tropomyosin and troponin.
