Answer 2

Answer:

Important parts of the human skeleton are explained as follows:

i) Skull: The skull protects the brain and is made up of 22 bones. All the bones in the skull are fixed and immovable except the lower jaw bone. The movement of the lower jaw allows us to open and close our mouth for chewing food and talking.

ii) Rib cage: It is the enclosure of bones located in the chest region. It is made up of curved bones. There are 12 pairs of ribs (24 bones) in an adult. The rib cage protects the heart and lungs.

iii) Vertebral column: It is a curved and flexible series of bones, extending from the neck to the lower back. It is also called the backbone or spine. There are 33 individual bones and vertebrae in it. The vertebral column helps us to straighten, bend or turn our back. It encloses and protects the spinal cord.

iv) Pelvis (hip): It is the large bony frame near the base of the spine to which the hindlimbs or legs are attached.

v) Femur: It is the thigh bone. Femur is the longest and strongest bone in our body. It bears most of the bodyweight while running, walking or jumping.
