#Bones of the skull skin

Below the orbit is the infraorbital foramen, which is the point of emergence for a sensory nerve that supplies the anterior face below the orbit.

#Bones of the skull skin

This provides for passage of a sensory nerve to the skin of the forehead.

Located near the midpoint of the supraorbital margin is a small opening called the supraorbital foramen. The upper margin of the anterior orbit is the supraorbital margin. The orbit is the bony socket that houses the eyeball and muscles that move the eyeball or open the upper eyelid. Also seen are the upper and lower jaws, with their respective teeth (Figure 2). This view of the skull is dominated by the openings of the orbits and the nasal cavity. The anterior skull consists of the facial bones and provides the bony support for the eyes and structures of the face. Which bone (yellow) is centrally located and joins with most of the other bones of the skull? Watch this video to view a rotating and exploded skull, with color-coded bones. The skull consists of the rounded brain case that houses the brain and the facial bones that form the upper and lower jaws, nose, orbits, and other facial structures. The 22nd bone is the mandible (lower jaw), which is the only moveable bone of the skull. In the adult, the skull consists of 22 individual bones, 21 of which are immobile and united into a single unit. The rounded brain case surrounds and protects the brain and houses the middle and inner ear structures. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws. It is subdivided into the facial bones and the brain case, or cranial vault (Figure 1). The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. Identify the bony openings of the skull.Identify the bones and structures that form the nasal septum and nasal conchae, and locate the hyoid bone.Name the bones that make up the walls of the orbit and identify the openings associated with the orbit.Define the paranasal sinuses and identify the location of each.Locate and define the boundaries of the anterior, middle, and posterior cranial fossae, the temporal fossa, and infratemporal fossa.Locate the major suture lines of the skull and name the bones associated with each.

List and identify the bones of the brain case and face.
