Smallest bone in human system is

Detailed Solution: Question 3

Stapes, one of the bones in the ear, is the smallest bone in the human body. Here are some key points about the stapes:

  • It is part of the ossicles, a group of three tiny bones in the middle ear.
  • The stapes helps transmit sound vibrations from the outer ear to the inner ear.
  • Its size is approximately 2.5 mm, making it the smallest bone.

This bone plays a crucial role in our ability to hear.

Topic in NCERT: Skeletal system

Line in NCERT: "each middle ear contains three tiny bones - malleus, incus and stapes, collectively called ear ossicles."

Detailed Solution: Question 6

Trasals, femur, metatarsals and tibia are bones of the legs which are involved in running during chasing the ball by a cricket player.

Topic in NCERT: Skeletal system

Save

Which of the following bones form a link between axial and appendicular skeleton?

Detailed Solution: Question 10

Clavicle is a bone that forms part of the pectoral girdle (part of appendicular skeleton) linking the scapula to the sternum (part of axial skeleton).

Topic in NCERT: Skeletal system

Test: Skeletal System (NCERT) - Question 11
Save

Out of the following pairs of the human skeletal parts, identify the wrongly matched pair

Detailed Solution: Question 11

Clavicle and glenoid cavity are parts of the pectoral girdle, not the pelvic girdle.

This is important because:

  • The pectoral girdle connects the upper limbs to the axial skeleton.
  • The pelvic girdle connects the lower limbs to the axial skeleton.
  • Understanding these differences is crucial for studying human anatomy.

Topic in NCERT: Appendicular skeleton

Line in NCERT: "the bones of the limbs alongwith their girdles constitute the appendicular skeleton."

Test: Skeletal System (NCERT) - Question 12
Save

The coxal of the pelvic girdle is formed by the fusion of

Detailed Solution: Question 12

The pelvic girdle is composed of two coxal (hip) bones. Each coxal bone consists of three separate parts: the ilium (short and straight bone), the ischium (lower elongated bone running parallel to vertebral column) and the pubis (inner smaller bone).

Topic in NCERT: Pelvic girdle and lower limb bones

Line in NCERT: "each coxal bone is formed by the fusion of three bones - ilium, ischium and pubis."

Test: Skeletal System (NCERT) - Question 13
Save

Which of the following statements are incorrect regarding a normal human?

  • (i) The skull is dicondylic.
  • (ii) Metacarpals are five in numbers.
  • (iii) Patella is a cup-shaped bone covering the knee dorsally.
  • (iv) Scapula is a large triangular flat bone, situated on the ventral side of the thorax.
  • (v) The pelvic girdle has two coxal bones.

Detailed Solution: Question 13

Option D is correct.

Patella is a cup-shaped sesamoid bone that covers and protects the anterior (ventral) surface of the knee joint; therefore stating it covers the knee dorsally is incorrect.

The scapula is a large triangular flat bone situated on the dorsal side of the thorax (behind the ribcage); describing it as located on the ventral side is incorrect.

The remaining statements are correct: the skull articulates with the first cervical vertebra via two occipital condyles (hence dicondylic), there are five metacarpals in each hand, and the pelvic girdle is formed by two coxal bones.

Final answer: Option D.

Test: Skeletal System (NCERT) - Question 14
Save

Appendicular skeleton includes

Detailed Solution: Question 14

The endoskeleton of mammals have two major divisions: (i) Axial skeleton, that lies along the longitudinal axis of the body. It supports and protects the organs of the head, neck and trunk. It includes skull, ribs, sternum and vertebral column, (ii) Appendicular skeleton, which is associated with the appendages. It consists of two girdles, the pectoral and pelvic girdles and the limb bones.

Topic in NCERT: Appendicular skeleton

Line in NCERT: "the bones of the limbs alongwith their girdles constitute the appendicular skeleton."

Test: Skeletal System (NCERT) - Question 15
Save

11th and 12th pair of ribs which are imperfectly formed and do not reach the sternum are called

Detailed Solution: Question 15

The last two pairs of ribs (11th and 12th) are called floating ribs as their anterior ends are not attached to either the sternum or the cartilage of another rib. The floating ribs provide protection to kidneys.

Topic in NCERT: Skeletal system

Line in NCERT: "last 2 pairs (11th and 12th) of ribs are not connected ventrally and are therefore, called floating ribs."

Test: Skeletal System (NCERT) - Question 16
Save

Which of the following is not a function of vertebral column?

Detailed Solution: Question 16

Tarsals and metacarpals are the bones of the limb, therefore, they are the part of appendicular skeleton and not the axial skeleton which consists of vertebral column.

Topic in NCERT: Vertebral column

Line in NCERT: "the vertebral column protects the spinal cord, supports the head and serves as the point of attachment for the ribs and musculature of the back."

Test: Skeletal System (NCERT) - Question 17
Save

The figure given here is of rib cage. Identify the parts labelled as A, B and C and select the correct option.

Detailed Solution: Question 17

Correct option: B.

Sternum is a flat median bone of the anterior thoracic wall that forms the front midline of the chest; this identifies label A as the sternum.

Ribs are curved flat bones that form the lateral walls of the thoracic cage; there are 12 pairs of ribs and they are represented by label B.

Vertebral column is the segmented series of vertebrae forming the posterior support of the trunk and providing dorsal attachment for the ribs; this corresponds to label C.

These identifications match option B, so option B is the correct choice.

Test: Skeletal System (NCERT) - Question 18
Save

Consider the following four statements (i) - (iv) and select the correct option.
(i) Actin is present in thin filament.
(ii) H-zone of striated muscle fibre represents both thick and thin filaments.
(iii) There are 11 pairs of ribs in man.
(iv) Sternum Is present on ventral side of the body.

Detailed Solution: Question 18

Actin is a globular protein present in thin filaments. There are 12 pairs of ribs in man. Sternun is a flat bone present on the ventral side of the body in the middle of the front of the chest.

Topic in NCERT: Locomotion and movement

Line in NCERT: "actin is present in thin filament."
"there are 12 pairs of ribs."
"sternum is present on the ventral side of the body."
"last 2 pairs (11th and 12th) of ribs are not connected ventrally and are therefore, called floating ribs."

Test: Skeletal System (NCERT) - Question 19
Save

Match column I with column II and select the correct option from the codes given below. 

Detailed Solution: Question 19

Correct answer: Option B.

There are 7 pairs of true ribs; these ribs are attached dorsally to the thoracic vertebrae and ventrally to the sternum by hyaline cartilage.

The next 3 pairs (8th-10th) are false ribs; they do not attach directly to the sternum but join the 7th rib indirectly by cartilage and are called vertebrochondral ribs.

The last 2 pairs (11th and 12th) are floating ribs; their anterior ends are not attached to the sternum.

Therefore the correct matching is A-(iii), B-(i), C-(ii), which corresponds to Option B.

Test: Skeletal System (NCERT) - Question 20
Save

Fill in the blanks to complete the sequence of vertebral counts starting from the skull:
Cervical (), Thoracic (), Lumbar (), Sacral ( ), Coccygeal ( ).

Detailed Solution: Question 20

The human vertebral column is divided into five regions with the following typical vertebrae counts:

Cervical: 7 vertebrae

Thoracic: 12 vertebrae

Lumbar: 5 vertebrae

Sacral: 1 segment formed by the fusion of 5 sacral vertebrae

Coccygeal: 1 segment formed by the fusion of 4 coccygeal vertebrae

Thus the correct sequence is 7, 12, 5, 1 (fused), 1 (fused), matching Option A.
