Question

What is the structure of muscle fibre ?

Answer 1

Heya !!!

Here's your answer !!!

Muscle fibres are the elongated cells present in muscular tissue...

These are surrounded by a connective tissue sheath.

Extracellular matrix is absent....

The plasma membrane of muscle fibre is called sarcolemma...

The cytoplasm of muscle fibre is called sarcoplasm...

The endoplasmic reticulum present in muscle fibre is called sarcoplasmic reticulum...

The mitochondria present in muscle fibre are called Sarcosomes..

The cytoplasm of a muscle fibre consists of several myofibrils...

Each myofibril has a thick (myosin) and thin (actin) myofilaments...

The regular arrangement of myosin and actin filaments is responsible for the alternate dark and light bands of a striated muscle...

Sarcoplasm also contains ATP , phosphocreatine , glycogen and myoglobin...

Hope this helps you :)
