Compare and contrast axial skeleton and appendicular skeleton Rating:
The axial skeleton and the appendicular skeleton are two major components of the human skeleton. The axial skeleton consists of the bones that make up the central axis of the body, including the skull, spine, and ribcage. The appendicular skeleton, on the other hand, consists of the bones that make up the upper and lower limbs, as well as the shoulder girdle and pelvic girdle.
One key difference between the axial skeleton and the appendicular skeleton is their location in the body. The axial skeleton runs down the midline of the body, while the appendicular skeleton is located on the sides of the body. This distinction is important because it determines the functions of these two sets of bones. The axial skeleton is primarily responsible for supporting the head and trunk, while the appendicular skeleton is responsible for movement and locomotion.
Another difference between the axial skeleton and the appendicular skeleton is the number of bones they contain. The axial skeleton has 80 bones in total, while the appendicular skeleton has 126 bones. This difference is largely due to the fact that the appendicular skeleton includes both the upper and lower limbs, which have many bones to allow for a wide range of movement.
Despite these differences, the axial skeleton and the appendicular skeleton are both integral parts of the human skeleton and work together to support the body and allow for movement. The axial skeleton provides the central support for the body, while the appendicular skeleton allows for the movement of the limbs. Both sets of bones also protect vital organs and provide attachment points for muscles, tendons, and ligaments.
In conclusion, the axial skeleton and the appendicular skeleton are two important components of the human skeleton that have distinct locations and functions. The axial skeleton is located along the midline of the body and is primarily responsible for supporting the head and trunk, while the appendicular skeleton is located on the sides of the body and is responsible for movement and locomotion. Both sets of bones are essential for maintaining the structure and function of the human body.
Compare and Contrast the Axial and Appendicular Skeletons
C Compare and contrast flat bones and long bones. Each disc is part of a joint that allows for some movement of the spine and acts as a cushion to absorb shocks from movements such as walking and running. The appendicular skeleton is comprised of the upper and lower extremities which include the shoulder girdle and pelvis. Describe the parietal bones. The cranium, which is boxlike in shape, consists of eight, large, flat bones: the frontal bone forms the forehead, the paired parietal bones build most of the superior and lateral walls of the cranium, the temporal bones lie behind the parietal bones, and the most posterior bone of the cranium is the occipital bone which forms the base and back wall of the skull. Difference Between Axis and Appendicular Skeleton. The skull is formed by the cranial and facial bones.
Difference Between Axial and Appendicular Skeleton
The cranial bones are eight bones that form the cranial cavity, which encloses the brain and serves as an attachment site for the muscles of the head and neck. The skeletal system in vertebrates is divided into the axial skeleton which consists of the skull, vertebral column, and rib cage , and the appendicular skeleton which consists of the shoulders, limb bones, the pectoral girdle, and the pelvic girdle. The mandible articulates with the base of the skull. The vertebral column is formed from 24 vertebrae, the sacrum, and the coccyx. It acts as a movable base for the tongue and is connected to muscles of the jaw, larynx, and tongue.
The function of the axial skeleton is to provide support and protection for the brain, the spinal cord, and the organs in the ventral body cavity. In the adult, the sacrum is typically composed of five vertebrae that fuse into one. The coccyx is typically 3—4 vertebrae that fuse into one. Axial Skeleton The axial skeleton contains 80 bones. The appendicular skeleton is composed of the bones of the limbs and girdles. In adults, the hip bones, or coxal bones, are formed by the fusion of three pairs of bones: the ilium, ischium, and pubis. Axial vs Appendicular Skeleton The difference between Axial and Appendicular skeleton is that the axial skeleton is the central axis of the body whereas the appendicular skeleton is mainly limbs and appendages.

Lateral undulations of land animal vertebral columns cause torsional strain. Apart from that, it protects the internal organs of the body, especially by the thorax. The human skeleton forms the base for the shape and functionality of the human body. The bony thorax encloses the delicate organs. These bones are fairly fragile and are susceptible to fractures. The mandible articulates with the base of the skull.
The two largest tarsals, the calcaneus and talus, carry most of the body weight. The phalanges are distal to the metacarpals. So in the case of the human body arms and legs are appendages. The hand includes the eight bones of the carpus wrist , the five bones of the metacarpus palm , and the 14 bones of the phalanges digits. The main difference between axial and appendicular skeleton is that the axial skeleton makes up the central axis of the body whereas the appendicular skeleton connects the appendages to the axial skeleton.
The fibula, or calf bone, parallels and articulates with the tibia. The ulna is located on the medial aspect pinky-finger side of the forearm. There are three different skeleton designs that fulfill these functions: hydrostatic skeleton, exoskeleton, and endoskeleton. For example, a fall with the arms outstretched causes the force to be transmitted to the clavicles, which can break if the force is excessive. They are present in the skeletal elements of the limbs, pectoral and pelvic girdle.
The bony thorax is formed from the sternum and 12 pairs of ribs. The patella is embedded in the tendon of the femoral extensors quadriceps. The tarsals are the seven bones of the ankle. The vertebral column is approximately 71 cm 28 inches in adult male humans and is curved, which can be seen from a side view. The Appendicular Skeleton contains the pelvic and pectoral.
Skull vertebrae ribs and sternum. The humerus is the largest and longest bone of the upper limb and the only bone of the arm. But the key difference between axial and appendicular skeleton is that the axial skeleton is to maintain posture, stability and balance, whereas the appendicular skeleton is to assist in locomotion, digital manipulation leading to feeding, and reproduction. The inner part of discs, the nucleus pulposus, hardens as people age and becomes less elastic. Around the age of 70, the sacrum and the coccyx may fuse together.
The skeletal framework of the upper limb is formed by 30 separate bones. There is also a notch on each side through which the spinal nerves, which serve the body at that level, can exit from the spinal cord. It is formed from three bones that fuse in the adult. There are 7 cervical vertebrae, 12 thoracic, and 5 lumbar vertebrae, which have common as well as unique features. It is composed of 126 bones of the limbs and the pectoral and pelvic girdles which attach the limbs to the axial skeleton.
Difference Between Axial and Appendicular Skeleton
The main difference between axial and appendicular skeleton is that the axial skeleton makes up the central axis of the body whereas the appendicular skeleton connects the appendages to the axial skeleton. The radius is located along the lateral thumb side of the forearm and articulates with the humerus at the elbow. However, instead of pushing against water, their fins or flippers became points of contact with the ground, around which they rotated their bodies. What is Axial Skeleton? There are 22 bones in the skull 6 auditory ossicles 26 vertebra 24 ribs a sternum and a hyoid bone. The appendicular skeleton consists of 126 bones in the body including the bones of the upper and lower limbs, and their connections to the axial skeleton.
