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

Detailed Solution for Test: Skeletal System (NCERT) - Question 13

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).

Test: Skeletal System (NCERT) - Question 14

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

Detailed Solution for Test: Skeletal System (NCERT) - Question 14

Clavicle and glenoid cavity are skeletal parts pelvic girdle.

Test: Skeletal System (NCERT) - Question 15

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

Detailed Solution for Test: Skeletal System (NCERT) - Question 15

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).

Detailed Solution for Test: Skeletal System (NCERT) - Question 18

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.

Test: Skeletal System (NCERT) - Question 19

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

Detailed Solution for Test: Skeletal System (NCERT) - Question 19

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.

Test: Skeletal System (NCERT) - Question 20

Skull of man is

Detailed Solution for Test: Skeletal System (NCERT) - Question 20

Skull of man is called dicondylic because it has two small protuberances known as occipital condyles at the posterior end. These condyles articulate with the atlas vertebra.

Test: Skeletal System (NCERT) - Question 21

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

Detailed Solution for Test: Skeletal System (NCERT) - Question 21

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.
