Q

Skeletal Muscle Anatomy (4 subsections)

A
  1. Muscle tissue is made up of bundles of fascicles
  2. Fascicles are made up of muscle fibres
  3. Muscle fibres are made of myofibrils
  4. Myofibrils are made of thick and thin filaments
    4a - Filaments = twisted strands of molecules that create contractions
  • Each bundle in each stage is surrounded by connective tissue which come together at the end to create tendons and ligaments

Dynamic Stretching (Repetitive movements of the body into increasingly deeper stretches)
