Answer 1

Striated muscle is also known as stripped or voluntary or skeletal muscle
-these cells are long cylindrical straight and unbranched in structure covering of muscle is called sarcolemma and their fluid is called sarcoplasm
-all the nuclei of muscle cell are arranged peripherally of the cell
-sarcoplasmic contains freely scattered granules like hemoglobin called myoglobin, - - - oxygen is stored in myoglobin.
-sarcoplasmic contains many long compact fibre, Fury it consists of both thick and thin myofilament
-thick myofilament is called primary myofilament Nd it is made up of myosin protein - thin myofilament is called secondary myofilament and it is made up of actin tropinin and trioo-myosin protein.
- muscle cell have to type of stripped structure dark band and light band
- dark band contains both thick and thin myofilament
- light band contains only thin myofilament
