What is skull and vertebrae?
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. The axial skeleton together with the appendicular skeleton form the complete skeleton.
What are the vertebrae bones classified as?
Irregular Bones
They are primarily spongy bone that is covered with a thin layer of compact bone. The vertebrae and some of the bones in the skull are irregular bones.
What is the skull called?
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain.
What is the scientific name of skull?
The cranium (Latin term for skull) is the most cephalad aspect of the axial skeleton. It is composed of 22 bones and divided into two regions: the neurocranium (which protects the brain) and the viscerocranium (which forms the face).
What bones belong to axial skeleton?
Your axial skeleton is made up of the 80 bones within the central core of your body. This includes bones in your skull (cranial and facial bones), ears, neck, back (vertebrae, sacrum and tailbone) and ribcage (sternum and ribs).
Are vertebrae irregular bones?
Irregular Bones Have Complex Shapes
For example, the vertebrae, irregular bones of the vertebral column, protect the spinal cord. The irregular bones of the pelvis (pubis, ilium, and ischium) protect organs in the pelvic cavity.
Is the skull a flat bone?
Flat bones are made up of a layer of spongy bone between two thin layers of compact bone. They have a flat shape, not rounded. Examples include the skull and rib bones. Flat bones have marrow, but they do not have a bone marrow cavity.
What is another term for head or skull?
brain, cranium, forehead, scalp, skeleton.
What is another name for a skull?

What is the name of the bones?
The skeleton
Skull – including the jaw bone. Spine – cervical, thoracic and lumbar vertebrae, sacrum and tailbone (coccyx) Chest – ribs and breastbone (sternum) Arms – shoulder blade (scapula), collar bone (clavicle), humerus, radius and ulna.
What are the 3 parts of axial skeleton?
The axial skeleton forms the central axis of the human body and consists of the skull, vertebral column, and thoracic cage.
What is in the appendicular skeleton?
The appendicular skeleton is comprised of the upper and lower extremities, which include the shoulder girdle and pelvis. The shoulder girdle and pelvis provide connection points between the appendicular skeleton and the axial skeleton to where mechanical loads transfer.
Which are irregular bones?
Irregular Bones.
They consist of cancellous tissue enclosed within a thin layer of compact bone. The irregular bones are: the vertebræ, sacrum, coccyx, temporal, sphenoid, ethmoid, zygomatic, maxilla, mandible, palatine, inferior nasal concha, and hyoid.
Which are the flat bones?
1. Flat Bones Protect Internal Organs. There are flat bones in the skull (occipital, parietal, frontal, nasal, lacrimal, and vomer), the thoracic cage (sternum and ribs), and the pelvis (ilium, ischium, and pubis). The function of flat bones is to protect internal organs such as the brain, heart, and pelvic organs.
Is the vertebrae a flat bone?
Examples of flat bones are the sternum (breast bone), ribs, scapulae (shoulder blades), and the roof of the skull (Figure 1). Irregular bones are bones with complex shapes. These bones may have short, flat, notched, or ridged surfaces. Examples of irregular bones are the vertebrae, hip bones, and several skull bones.

What are the 4 types of skeletons?
Though bony endoskeletons are the best known, the animal kingdom features three other types of skeleton: exoskeletons, cartilaginous endoskeletons, and hydrostatic skeletons.
What is axial and appendicular skeleton?
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.
Is skull axial or appendicular?
What are the axial and appendicular skeleton?
The bones of the human skeleton are divided into two groups. The appendicular skeleton includes all the bones that form the upper and lower limbs, and the shoulder and pelvic girdles. The axial skeleton includes all the bones along the body’s long axis.
