Sarcolemma, sarcoplasm and sarcoplasmic reticulum refer to particular type of cell in our body. Which is this cell and to what parts of that cell do these names refer to ?

Explanation

### Step-by-Step Solution:

1. **Identify the Cell Type**: The terms sarcolemma, sarcoplasm, and sarcoplasmic reticulum refer to components of muscle cells. Specifically, they are associated with muscle fibers.

2. **Define Sarcolemma**: The sarcolemma is the plasma membrane that surrounds each muscle fiber. It acts as a barrier that separates the interior of the muscle fiber from the external environment.

3. **Define Sarcoplasm**: The sarcoplasm is the cytoplasm of the muscle fiber. It contains various organelles, including myofibrils, which are essential for muscle contraction, as well as multiple nuclei.
