Nervous Coordination: Muscle Contraction
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.
