MUSCLE FORM + FUNCTION
LO's:
Structure of the 3 types of muscle
Organisation of skeletal muscle
Basic understanding of elements of the contractile apparatus
Process of muscle contraction, sliding filament theory
Muscle fibre types
Muscle disease
Types:
Skeletal
Striated
Myofibres
Epimyseum
Covers whole muscle
Perimyseum
Covers fascicle
Endomyseum
Basement membrane
Extracellular matrix
Sarcolemma
Muscle cell membrane
Cardiac
Striated/branched
Gap-junctions
For contraction
Intercalated discs
Many mitochondria
Controlled by autonomic nervous system
Smooth
Where:
