Musculotendinous Flashcards
Tissues in MU
Muscle cells
tendons
connective tissue and fascia
types of connective tissue
Epimysium: surrounds entire muscle
Perimysium: surrounds each fascicle
Endomysium: surrounds each muscle cell
Connective tissue sheaths are ______
continuous with tendons
Behavioral Properties
Contractility: ability to shorten to generate force
Excitability: ability to react to a stimulus
Extensibility: ability to be stretched
Elasticity: ability to recoil after being stretched
“active” tissue
Contractile component= Muscle fibers (CC)
-Properties: contractility and excitability
“passive” tissues
series elastic component= tendons
Parallel elastic component=fascia and other connective tissues (epi, peri, endo)
-Properties: extensibility and elasticity
Hyperplasia
increase in fiber number
-can only happen in birds and amphibians
Hypertrophy
increase in fiber diameter (humans)
