Consider the diagram given below.

Parts labelled as A, B, C, D, E and F respectively indicate.

(1) Sacrum, ilium, pubis, femur, tibia and fibula

(3) Sacrum, pubis, ilium, femur, tibia and fibula

(4) Ilium, sacrum, pubis, femur, tibia and fibula

In old age, stiffness of joints is due to the 

(1) hardening of bones

(2) inefficiency of muscles

(3) decrease in synovial fluid

(4) enlargement of bones

Oxygen content reduction makes the glycolyse (glycogenesis) intensity increased due to

(1) increase of ADP concentration in cell

(2) increase of ${\mathrm{NAD}}^{+}$ concentration in cell

(3) increase of ATP concentration in cell

(4) increase of concentration of peroxides and free radicals 

Pick out the correct match

Sarcomere is the area between:

(1) 2 H-zones       

(2) 2 Z-lines

Light bands (thin filaments) contain actin and are called:

(1) A-bands or Isotropic band            

(2) A-bands or Anisotropic bands

(3) I-bands or Isotropic bands

Dark bands (thick filaments) contain myosin and are called:

(1) A-bands or Isotropic band            

(2) A-bands or Anisotropic bands

(3) I-bands or Isotropic bands           

(4) I-bands or Anisotropic bands
