(b) Red and White musclesActin
Myosin
1 Actin is a thin contractile protein. 1 Myosin is a thick contractile protein. 2. It is present in light bands and is called an isotropic band. 2 It is present in dark bands and is called an anisotropic band.
(c) Pectoral and Pelvic girdleRed muscle fibre
White muscle fibre
1 Red muscle fibres are thin and smaller in size. 1 White muscle fibres are thick and larger in size. 2 They are red in colour as they contain large amounts of myoglobin. 2 They are white in colour as they contain small amounts of myoglobin 3 They contain numerous mitochondria. 3 They contain less number of mitochondria. 4 They carry out slow and sustained contractions for a long period. 4 They carry out fast work for short duration. 5 They provide energy by aerobic respiration. 5 They provide energy by anaerobic respiration.
(a) Actin and MyosinPectoral girdle
Pelvic girdle
1 It is a skeletal support from where the forelimbs of vertebrates are attached. 1 It is a skeletal support form where the hind limbs of vertebrates are attached. 2 It is composed of two
Bones namely, clavicle or collar bones and scapula or shoulder bone.
2 It is composed of three bones, upper ileum, inner pubic, and ischium.
