Find the incorrect statement:
(A) Contraction of external intercostals muscles in man causes expansion of lungs along the Antero-posterior axis.
(B) Contraction of diaphragm increases the volume of lungs along the supero inferior axis in human.
(C) Contraction of external inter costal muscles increases the volume of lungs along Antero-posterior axis in rabbit.
(D) Contraction of diaphragm increases the volume of lungs along the Antero- posterior axis in rabbit.
Correct Option: (C) Contraction of external inter costal muscles increases the volume of lungs along Antero-posterior axis in rabbit.
Explanation:
Rabbit is quadripedal so external intercostals muscle will expand the lung in supero-inferior axis while diaphragm will act along antero – posterior axis.
