Study Notes
Cranial Bones
- The frontal bone is a thick, unpaired structure that forms the anterior and superior portion of the skull. It protects the frontal lobe of the brain and forms the superior aspect of the orbit.
- The frontal lobe contains a small depression called the glabella, which is the smooth part of the forehead, between the eyebrows.
- The temporal bone is a paired structure located at the sides and bases of the skull. It can be divided into several different parts and processes.
- Squamous part
- Mastoid part
- Temporal part
- Petrous part
- Styloid process
- Zygomatic process
- Protecting the brain, the temporal bone also surrounds the middle and inner portions of the ear and connects with the lower mandible (jawbone) to allow the mouth to open and close. Many cranial nerves pass over the temporal bone.
- The parietal bone is a paired structure that forms the majority of the sides and roof of the skull. It is large and thin, with four borders and angles.
- The occipital bone is a trapezoidal-shaped bone forming the base of the skull. It is the most posterior cranial bone and it borders both parietal bones. Where they meet is known as the lambdoid suture.
- The sphenoid bone resembles the shape of a butterfly and is located in the middle of the skull between the frontal and temporal bones. The superior surface of the sphenoid body contains bony landmarks, such as the sella turcica, which is a saddle-shaped depression where the pituitary gland is located.
- The ethmoid bone is a light, spongy bone located between the eye sockets and behind the nasal cavity.
