What is the function of the axial and appendicular skeleton in the human body?
What is skeleton?
A skeleton is the basic foundational structure that holds an animal's body together. There are various types of skeletons, including the exoskeleton, which is an organism's rigid outer shell, and the endoskeleton, which provides internal support.
What is the difference between the axial and appendicular skeleton?
A) The axial skeleton helps with temperature regulation and the appendicular skeleton helps with blood flow.
B) The axial skeleton protects vital internal organs and the appendicular skeleton allows for movement.
C) The axial skeleton allows for movement and the appendicular skeleton protects vital internal organs.
D) The axial skeleton helps with blood flow and the appendicular skeleton helps with temperature regulation.
Answer:
The axial skeleton safeguards vital internal organs and the appendicular skeleton allows for movement. The correct option is B.
A skeleton serves as the framework that supports and protects the body of an animal. In the human body, the axial skeleton, including the skull, vertebrae, ribs, and sternum, forms the central axis. This portion of the skeleton provides structural support, protects vital internal organs such as the brain, heart, and lungs, and assists in maintaining an upright posture.
On the other hand, the appendicular skeleton consists of the limbs and girdles, which are responsible for movement. The pectoral girdle, also known as the shoulder girdle, is a crucial component of the appendicular skeleton. It is composed of four bones – two clavicles and two scapulae – that connect the upper limbs to the trunk of the body, allowing for various arm movements.
Overall, while the axial skeleton focuses on protecting internal organs and providing structural support, the appendicular skeleton facilitates movement and locomotion. Together, these two components work in harmony to ensure the functionality and stability of the human body.
