The axial skeleton forms the central axis of the human body and consists of the skull, vertebral column, and thoracic cage.
Q. What three parts make up the axial skeleton?
The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage. The bones of the appendicular skeleton (the limbs and girdles) “append” to the axial skeleton.

Q. What are the 3 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 animal, including humans. The primary divisions of the skeleton system are the head, thorax, and vertebral column. The human cranium supports the structures of the face and forms the brain cavity.
Q. What are the three main parts of a skeleton?
It includes the skull, vertebral column (spine), and rib cage. The bones of the axial skeleton, along with ligaments and muscles, allow the human body to maintain its upright posture.
Q. Are ear ossicles parts of skull?
The human skull is comprised of a total of 22 separate bones (excluding the ear ossicles and hyoid bone).
Q. What are the 5 bone types?
There are five types of bones in the skeleton: flat, long, short, irregular, and sesamoid.
Q. What are the four main bone types?
The four principal types of bones are long, short, flat and irregular.
Q. Why do bones have different shapes and sizes?
Your bones are different shapes and sizes because they have different jobs to do. They are divided into four groups: Long bones. They have a diaphysis, epiphyses and a hollow centre.
Q. Why are strong bones light in weight?
Your bones are strong enough to support your weight, but light enough to allow movement. They protect your delicate internal organs and act as a storehouse for minerals, such as calcium.
Q. Do bones have pores?
Unlike compact bone that is mostly solid, spongy bone is full of open sections called pores. If you were to look at it in under a microscope, it would look a lot like your kitchen sponge. Pores are filled with marrow, nerves, and blood vessels that carry cells and nutrients in and out of the bone.
Q. What part of the body are responsible for movement?
The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.
Q. What are the 3 types of movement?
The different types of movement that are permitted at each joint are described below.
- Flexion – bending a joint.
- Extension – straightening a joint.
- Abduction – movement away from the midline of the body.
- Adduction – movement towards the midline of the body.
- Circumduction – this is where the limb moves in a circle.
