Presentation on theme: "Essential of contraction"— Presentation transcript:

1 Essential of contraction
Locomotion Essential of contraction

2 Muscle contraction Actin Myosin Enzymes Energy Calcium
Low molecular weight thin Myosin High molecular weight thick Enzymes Energy Calcium

3 Ciliary Action Cilium Pattern of beat Bundles of fibrilles Organelle
Small/hair-like Many Pattern of beat Power and recovery strokes Metachronal

4 Flagellary Action Structure Functionality
9+2 arrangement of contractile fibrils Usually in pairs or small numbers Functionality Assymetrical beat beat that pulls rather pushes

5 Amoeboid Movement Structure Hyaline cap Cytoplasm = colloid
Liquid or solid phase Gel or liquid Ectoplasm and endoplasm Cyclosis- cytoplasmic streaming

6 Amoeboid Movement Mechanisms Push Pull Actin, myosin, ATP, Ca++
