Answer 1

Answer:

Chest bone or Rib Cage: It forms a cone- shaped bony cage. The bones of the cage are called ribs. There are 12 pairs of the ribs. They attached to the vertebral column. The rib-cage protects the lungs and the heart.

Backbone or Vertebral Column: The vertebral column extends from the base of the skull to the hip. It consists of 33 small rings; called vertebrae which are joined from end-to-end.

Ball and socket joint: In this joint the rounded end of one bone fits into the cavity (hollow space) of another bone. It permits movement in all directions. The joints between shoulder and the upper arm is an example of ball and socket joint. Similarly, the joint between thigh and hip is an example of ball and socket joint.

Answer:

Hi,

Explanation:

$\huge\boxed{\mathfrak\red{Answers:-}}$

1. Ribcage :- The rib cage is the arrangement of ribs attached to the vertebral column and sternum in the thorax of most vertebrates that encloses and protects the vital organs such as the heart, lungs and great vessels.

2. Backbone :- The backbone is the vertebral column of the vertebrate. The backbone is made up of the bones, muscles, tendons and other tissues that reach from the base of the skull to the tailbone. The backbone encloses the spinal cord and the fluid surrounding the spinal cord.

3. Ball and socket joint :- The ball and socket joint is a type of synovial joints in which one bone is hooked into the hollow space of another bone. This type of joint helps in rotatory movement. It enables the bone to move in many places.
