Spheroid Bone

A compound bone that forms the base of the cranium, behind the eye and below the front part of the brain.

Frontal Bone

The bone that forms the front part of the skull and the upper part of the eye sockets.

Coronal Suture

The transverse suture in the skull separating the frontal bone from the parietal bones.

Parietal Bone

A bone forming the central side and upper back part of each side of the skull.

Squamous Suture

Connects the temporal squama with the lower border of the parietal bone

Lamboid Suture

A dense, fibrous connective tissue joint on the posterior aspect of the skull that connects the parietal bones with the occipital bone.

Occipital Bone

The bone that forms the back and base of the skull, and through which the spinal cord passes.

Temporal Bone

Either of a pair of bones that form part of the side of the skull on each side and enclose the middle and inner ear.

External Accoustic Meatus

Also called the ear canal, is the tube running from the outer ear to the middle ear.

Mastoid Process

A conical prominence of the temporal bone behind the ear, to which neck muscles are attached, and which has air spaces linked to the middle ear.

Styloid Process

A slender projection of bone, such as that from the lower surface of the temporal bone of the skull, or those at the lower ends of the ulna and radius.

Lacrimal Bone

A small bone forming part of the eye socket.

Ethmoid Bone

A square bone at the root of the nose, forming part of the cranium, and having many perforations through which the olfactory nerves pass to the nose.

Occipitomastoid Suture

The suture between the occipital and the temporal bones; a continuation of the lamboid suture.

Nasal Concha

Any of several thin, scroll-like bones in the sides of the nasal cavity; resembles a spiral shell.
