Muscle Mechanics and Training

EXSS1029 Lecture Notes - Lecture 4: Myocyte, Titin, Sarcomere

Week 4 Notes Fiber > Fibril > Filament Sarcomeres in Series: eg. one sarcomere develops 10 units of force = 2 muscle cells x 2 sarcomeres = 4 load units force is transmitted from one tendon end to the other through each ...

EXSS1029 Lecture Notes - Lecture 3: Physiological Cross-Sectional Area, Costamere, Rectus Femoris Muscle

Week 3 Notes Myofibrils transmission of force: force exits the z disc and is transferred to the tendon end of thin filaments bind to transmembrane protein complexes called costameres costamere: connects sarcomere to the...
