Question

Structure of striated muscle ,muscle fibre,filament,

Answer 1

STRIATED MUSCLE TISSUE

Micrograph showing skeletal striated muscle (fibularis longus). HPS stain. Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres, in contrast with smooth muscle tissue which does not.

MUSCLE FIBRE

Each muscle fiber is a single cell. Each cell consists of a structure including the sarcolemma, nuclei, sarcoplasm, motor nerve endings, myofibrils, sarcomeres, mitochondria, lysosomes, and golgi complex. The sarcolemma is the membrane surrounding the muscle fiber.

FILAMENT

filaments of myofibrils constructed from proteins. Protein filament, a long chain of protein subunits, such as those found in hair, muscle, or in flagella. Part of a stamen, the male part of a flower. Hypha, a thread-like cell in fungi and Actinobacteria.
