The sphenoid and ethmoid bones can be located using the transverse plane of the skull and will be discussed in the section to follow. On the anterior maxilla, just below the orbit, is the infraorbital foramen. These are anatomical models created by digital artists based on their study of human anatomy. These produce swelling of the mucosa and excess mucus production, which can obstruct the narrow passageways between the sinuses and the nasal cavity, causing your voice to sound different to yourself and others. They are most common among young children (ages 0–4 years), adolescents (15–19 years), and the elderly (over 65 years). Inside the skull, the base is subdivided into three large spaces, called the anterior cranial fossa, middle cranial fossa, and posterior cranial fossa (fossa = "trench or ditch") ([link]).
A ligament that anchors the mandible during opening and closing of the mouth extends down from the base of the skull and attaches to the lingula. Breast intervention.

Numerous bony openings, or foramina, are also associated with different cranial bones and allow the passage of important nerves and blood vessels. The two suture lines seen on the top of the skull are the coronal and sagittal sutures. Finally, the lambdoid suture connects the occipital bone to the parietal bones. Inside the skull, the floor of the cranial cavity is subdivided into three cranial fossae (spaces), which increase in depth from anterior to posterior (see [link], [link] b, and [link]). Diccionario Visual (es). This second feature is most obvious when you have a cold or sinus congestion. This opening provides for passage of the nerve from the hearing and equilibrium organs of the inner ear, and the nerve that supplies the muscles of the face. Sphenoid bone: Just anterior to the temporal bones, the sphenoid is a single bone that stretches through the skull from left to right. Superior orbital fissure—This large, irregular opening into the posterior orbit is located on the anterior wall of the middle cranial fossa, lateral to the optic canal and under the projecting margin of the lesser wing of the sphenoid bone. Lateral view of the skull labeled anatomy. The shallow space above the zygomatic arch is the temporal fossa. Become a member and start learning a Member.
Fractures of the facial skeleton are relatively common and most frequently result from road traffic collisions, fist fights, and falls. The ethmoid bone also forms the lateral walls of the upper nasal cavity. The temporal bones each have an opening for the ear canal. This flattened region forms both the roof of the orbit below and the floor of the anterior cranial cavity above (see [link] b).

One of the paired bones that project from the lateral walls of the nasal cavity to form the largest and most inferior of the nasal conchae. Chemotherapeutic agents.
Stylomastoid foramen. The ethmoid bone houses the olfactory bulbs and is a place of passage for the olfactory fibers so the brain can process smell. Common wisdom has it that the temporal bone (temporal = "time") is so named because this area of the head (the temple) is where hair typically first turns gray, indicating the passage of time. Shoulder girdle radiography. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The paired bones are the maxilla, palatine, zygomatic, nasal, lacrimal, and inferior nasal conchae bones. Cranial Bones and Sutures. Skull lateral view anatomy. The temporal bones are the two bones that sit on each side of the head forming the sides of the cavity that houses the brain. It extends from the lesser wings of the sphenoid bone anteriorly, to the petrous ridges (petrous portion of the temporal bones) posteriorly. Fractures of the cranium typically arise from blunt force or penetrating trauma. The foramen magnum, which accommodates the spinal cord, is a large hole in the occipital bone.
Canal through which sounds collected by the auricle (outer section of the ear) reach the tympanic cavity, a hollow in the temporal bone. This cavity is bounded superiorly by the rounded top of the skull, which is called the calvaria (skullcap), and the lateral and posterior sides of the skull. Atlanta, GA; [cited 2013 Mar 18]. Interactive Link Questions.

Is divided at the midline by a small area of the ethmoid bone. The brain case consists of eight bones. This cartilage also extends outward into the nose where it separates the right and left nostrils.
Anatomically, the cranium can be subdivided into a roof and a base: - Cranial roof – comprised of the frontal, occipital and two parietal bones.
