What is the difference between axial and appendicular system?
Your axial skeleton is made up of the bones in your head, neck, back and chest. Your appendicular skeleton is made up of everything else — the bones that attach (append) to your axial skeleton. Your appendicular skeleton includes the bones in your shoulders, pelvis and limbs, including your arms, hands, legs and feet.
What are the 3 parts of the axial system?
The axial skeleton forms the central axis of the human body and consists of the skull, vertebral column, and thoracic cage.
What are the 4 parts of the axial?
The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage.
Is Atlas appendicular or axial?
The axial skeleton consists of four types of vertebrae (Figure 5.4). Most anteriorly is a single cervical vertebra, the atlas, that articulates with the occipital condyles of the skull.
What is axial skeleton system?
The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate. In the human skeleton, it consists of 80 bones and is composed of six parts; the skull (22 bones), also the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column.
What are the example of axial?
The axial skeleton includes the skull and all the cranial bones, the spine, the ribs and the hyoid bone.
Is the femur axial or appendicular?
appendicular skeletal
The femur is the appendicular skeletal bone connected to the pelvis at the acetabulum, a bony ring formed by the fusion of three bones: the ilium, ischium, and pubis.

Is hyoid axial or appendicular?
axial skeleton
Although it is not found in the skull, the hyoid bone is considered a component of the axial skeleton. The hyoid bone lies below the mandible in the front of the neck.
Is pelvis axial or appendicular?
The appendicular skeleton is everything else. It’s everything that attaches on to the axial skeleton. Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.
Is the pelvis axial or appendicular?
It’s everything that attaches on to the axial skeleton. Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.
What is included in axial skeleton?
The axial skeleton consists of the braincase (cranium) and the backbone and ribs, and it serves primarily to protect the central nervous system. The limbs and their girdles constitute the appendicular skeleton. In addition, there are skeletal elements derived from the gill arches of primitive vertebrates,…
How many axial bones are there?
80 bones
The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum. The appendicular skeleton consists of 126 bones and includes the free appendages and their attachments to the axial skeleton.
