Explanation / Answer

29. The procerus muscle located on upper part of the lateral nasal cartilage. It helps to pull the part of the skin between the eyebrows downward which assist in flaring of nostrils. So, the correct option is A here.

30. The orbicularia oris is also known as the kiss muscle because it encircles the lips and helps in puckering the lips. So, the option is B here.

31. The frontal belly of occipitofrontalis muscle located on the forehead. So, the wrinkling of burrow (forehead) is caused by the contraction of this muscle. The correct option is D here.

32. The movement of eye is controlled by the central nervous system. For the lateral movement of eye, lateral and medial rectus muscles are mainly responsible. If the noise comes from the left side, the left eye is moved by the lateral rectus and the right is moved by the medial rectus. So, the correct option is D here.

33. The trochlea of superior oblique moves through a pull like loop for the movement of eye. It is an extrinsic eye muscle, helps in eye movement. So, the correct option is E here.
