Match the following columns and select the correct option.

  1. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
  2. (a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)
  3. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)
  4. (a)-(iii), (b)-(ii), (c)-(iv), (d)-(i)

Answer

(3) (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

Solution

As per NCERT:

(a) The last 2 pairs (11th and 12th) of ribs are not connected ventrally to the sternum and are called floating ribs ⇒ (iv)

(b) The acromion (expanded end of the spine of the scapula) articulates with the clavicle ⇒ (iii)

(c) The scapula is a large triangular flat bone situated in the dorsal part of the thorax between the second and the seventh ribs ⇒ (i)

(d) The glenoid cavity of the scapula articulates with the head of the humerus to form the shoulder joint ⇒ (ii)

∴ (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

Answer: (3)

Select the correct option :

  1. Each rib is a flat thin bone and all the ribs are connected dorsally to the thoracic vertebrae and ventrally to the sternum
  2. There are seven pairs of vertebrosternal, three pairs of vertebrochondral and two pairs of vertebral ribs
  3. 8th, 9th and 10th pairs of ribs articulate directly with the sternum
  4. 11th and 12th pairs of ribs are connected to the sternum with the help of hyaline cartilage.

Which of the following muscular disorders is inherited?

  1. Myasthenia gravis
  2. Botulism
  3. Tetany
  4. Muscular dystrophy

Calcium is important in skeletal muscle contraction because it

  1. detaches the myosin head from the actin filament
  2. binds to troponin to remove the masking of active sites on actin for myosin
  3. prevents the formation of bonds between the myosin cross bridges and the actin filament
  4. activates the myosin ATPase by binding to it

Out of 'X' pairs of ribs in humans only 'Y' pairs are true ribs. Select the option that correctly represents values of X and Y and provides their explanation.

  1. X = 12, Y = 5; True ribs are attached dorsally to vertebral column and sternum on the two ends
  2. X = 24, Y = 2; The true ribs are dorsally attached to vertebral column but are free on ventral side
  3. X = 24, Y = 12; True ribs are dorsally attached to vertebral column but are free on ventral side
  4. X = 12, Y = 7; True ribs are attached dorsally to vertebral column and ventrally to the sternum

Osteoporosis, an age-related disease of skeletal system, may occur due to

  1. immune disorder affecting neuromuscular junction leading to fatigue
  2. high concentration of Ca++ and Na+
  3. decreased level of estrogen
  4. accumulation of uric acid leading to inflammation of joints.
NEET 2016 (Phase 2)
