Muscle Structure Flashcards
1
Q
Epysium
A
Sheath of fibrous elastic tissue surrounding a muscle
2
Q
Fascile
A
Functional bundle of muscle fibre
3
Q
Perimysium
A
Surrounds the fascile
Sheath of connective tissue surrounding a bundle of muscle fibres
4
Q
Endomysium
A
Surrounds individual muscle fibres
5
Q
Sacrolemma
A
Thin plasma membrane surrounding a single
muscle fibre.
6
Q
Myofibril
A
Contractile elements inside muscle cell/fibres
7
Q
Sacroplasm
A
Found between the myofibrils
8
Q
Transverse tubules
A
Found in sacroplasm and penetrate into the cells.
9
Q
Sacroplasmic Reticulum
A
Surrounds myofibrils and store/release calcium
10
Q
Sarcomere
A
Where to contraction occurs in the myofibril.
Sliding happens between Actin and Myosin Fibres. Thick and think filament. Thin filament can slide past the thick filament.
Basis for muscle contraction.
