Plasma membrane of a skeletal muscle fiber - _________Extension of the sarcolemma that dives into the muscle fiber and surrounds
Tpy6a [65]

Answer:

1. Sarcolemma

2. T-Tubule

3. Sarcoplasmic reticulum

4. Terminal Cisternae

5. Myofibrils

6. Myofilament

7.Thick filament

8. Thin filament

Explanation:

These are all parts of the skeletal muscle and they are all involved in the contraction of your muslces.

The sacrolemma is also known as the myolemma. It is a specialized plasma membrane of the skeletal muscle cell. It is an excitable membrane that shares similarities to the cell membrane of a neuron cell.

The T-tubule extends from the sarcolemma to the sarcoplasmic reticulum (SR). This is the smooth endoplasmic reticulum of the muscle cell. When the sarcolemma gets excited, it triggers the SR to release the calcium ions stored in it. The release of Calcium ions triggers the contraction of myofilaments.

There are two types of myofilaments, the thick myofilament and the thin myofilament. These myofilaments contain contractile proteins, actin and myosin. Thick myofilaments contain myosin where one thick myofilament contains 300 myosin molecules. Thin myofilaments contain contractile and regulatory proteins. These myofilamens make up myofibrils.
