15.7 Structure of skeletal muscle

Three types of muscles in the body:

Myofibrils

Sarcoplasm:

Microscopic structure of skeletal muscle:

The structure of these filaments and their constituent molecules is shown above:

Types of muscle fibre: slow-twitch fibres

Types of muscle fibre: Fast-twitch fibres

Neuromuscular junctions: part 1

Neuromuscular junctions: part 2

Comparison of the neuromuscular junction and a synapse:
