Introduction:
The skeleton system is made up of different types of bones. The skeleton gives a structural framework to the body and protects all the internal organs of the body. The Skeleton system is made up of 206 bones. The Skeleton system is divided into two types axial skeleton and appendicular skeleton.
Answer to Problem 22A
Correct answer:
The correct answer is option (c) hip bone.
Explanation of Solution
Explanation/justification for the correct answer:
Option (c) hip bone. Axial skeletons are the skeletons that are present along the axis of the body. The axial skeleton includes ribs, sternum, skull and vertebral column. Hip bone comes under an appendicular skeleton. Thus, the hip bone is the correct answer.
Explanation for incorrect answer:
Option (a) skull. Axial skeletons are the skeletons that are present along the axis of the body. Skull is a group of bones that forms the human head and protects the brain and face. Skull consists of 29 bones joined together by suture type of joint. Skull is a part of the axial skeleton thus, it cannot be a correct option.
Option (b) ribs. Axial skeletons are the skeletons that are present along the axis of the body. Ribs are a group of bones that protects the lungs and heart. There are twelve pairs of ribs present in the human body or 24 in total. Ribs are a part of the axial skeleton thus, it cannot be a correct answer.
Option (d) vertebral column. Axial skeletons are the skeletons that are present along the axis of the body. The vertebral column protects the spinal cord and provides muscle attachment. The vertebral column is made up of 26 bones. The vertebral column is a part of the axial skeleton thus, it cannot be a correct answer.
Option (c) is a correct option because the hip bone is a part of the appendicular skeleton and not of the axial skeleton.
