What does the axial skeleton?

Human Axial Skeleton. The axial skeleton forms the central axis of the body and includes the bones of the skull, ossicles of the middle ear, hyoid bone of the throat, vertebral column, and the thoracic cage (ribcage) (Figure 1).

Consequently, what is the axial skeleton responsible for?

The axial skeleton supports and protects the brain, spinal cord and many of the internal organs. It also provides sites for the attachment of other bones and muscles in the body and protects the nerves and blood vessels from the brain and spinal cord.

Secondly, which of the following bones are part of the axial skeleton? Skull, clavicle, vertebral column, shoulder girdle, humerus, pelvic girdle, and femur. The skull and vertebral column are part of the axial skeleton.

Herein, what are the bones of the axial and appendicular skeleton?

Axial and Appendicular Skeletons The axial skeleton forms the central axis of the body and consists of the skull, vertebral column, and thoracic cage. The appendicular skeleton consists of the pectoral and pelvic girdles, the limb bones, and the bones of the hands and feet.

What are the main parts of the axial skeleton?

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), the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column.

What are the 7 axial bones?

29 bones in the head – (8 cranial and 14 facial bones) and then also 7 associated bones (6 auditory ossicles and the Hyoid Bone)
25 bones of the thorax – (the sternum and 24 ribs)
26 bones in the vertebral column (24 vertebrae, the sacrum, and the coccyx)

What are the 3 main components of the axial skeleton?

The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate. It consists of 80 bones and is composed of three parts; skull, vertebral column and the ribs.

What are the 2 types of skeletons?

Types of skeletons. There are two major types of skeletons: solid and fluid. Solid skeletons can be internal, called an endoskeleton, or external, called an exoskeleton, and may be further classified as pliant (elastic/movable) or rigid (hard/non-movable).

What do you mean by appendicular skeleton?

The appendicular skeleton includes the skeletal elements within the limbs, as well as supporting shoulder girdle pectoral and pelvic girdle. The word appendicular is the adjective of the noun appendage, which itself means a part that is joined to something larger.

What is the function of the axial and appendicular skeleton?

Together, all the bones of the appendicular skeleton are responsible for making movement of our bodies possible. While the axial skeleton protects and supports the internal organs and the body as a whole, both work together to allow us to operate and function normally.

What is the smallest bone in the body?

stapes

What is the function of appendicular skeleton?

The human appendicular skeleton is composed of the bones of the upper limbs (which function to grasp and manipulate objects) and the lower limbs (which permit locomotion). It also includes the pectoral (or shoulder) girdle and the pelvic girdle, which attach the upper and lower limbs to the body, respectively.

What Bones consist of the appendicular skeleton?

The bones of the appendicular skeleton make up the rest of the skeleton, and are so called because they are appendages of the axial skeleton. The appendicular skeleton includes the bones of the shoulder girdle, the upper limbs, the pelvic girdle, and the lower limbs.

What are bones made of?

Made mostly of collagen, bone is living, growing tissue. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.
