Nervous Coordination: Muscle Contraction

Huge links to nervous system and respiration
Use of a large flow diagram to show whole process
Muscles act in antagonistic pairs against an incompressible skeleton
Importance of understanding both gross and microscopic structure of skeletal muscle
The role of actin, myosin, calcium ions, and ATP in myofibril contraction
Roles of calcium ions and tropomyosin in actinomyosin bridge formation cycle
The role of troponin is not required
The importance of ATP and phosphocreatine in muscle contraction
Understanding the structure, location, and properties of slow and fast skeletal muscle fibres
Sound knowledge of the sliding filament theory and the link between contraction and synaptic transmission at the neuromuscular junction is necessary.
