What is the inferior view of the skull?
The foramen magnum is the largest foramen on the skull base, through which the spinal cord enters the cranium. The occipital condyles occupy the anterolateral aspects of the foramen magnum and are the site of articulation with the cervical atlas.
What is the inferior surface of the skull called?
Foramen magnum (inferior view) Just posterior to the middle of the skull is the foramen magnum. This is Latin for large hole. It allows the spinal cord to pass inferiorly out of the cranial vault, and also the vertebral arteries to enter the skull and provide the posterior input to the circle of Willis.
What is inferior to the cranium?
The structures below the cranium (more specifically the neurocranium) and superior to the mandible are: facial bones – lacrimal, ethmoid, maxilla, zygomatic, nasal bones, vomer.
What area is located on the posterior and inferior skull?
RA & Anatomy
| Question | Answer |
|---|---|
| Occurs where the parietal bones meet the occipital bone posteriorly | Lambdoidal Suture |
| Most posterior & inferior of the cranial bones, forms the posterior cranial fossa | Occipital Bone |
| Located medially on the inferior aspect of the skull, where brain stem connects to the brain | Foramen Magnum |
What is inferior view in anatomy?
Inferior or caudal – away from the head; lower (example, the foot is part of the inferior extremity). Medial – toward the midline of the body (example, the middle toe is located at the medial side of the foot).
What structure passes through the large opening shown in this inferior view of the skull?
The largest opening on the inferior view is the foramen magnum of the occipital bone, through which the spinal cord, vertebral arteries, and eleventh cranial/accessory nerve pass.
What is the large hole on the inferior surface of the skull called Why is it there?
The foramen magnum (Latin: great hole) is a large, oval-shaped opening in the occipital bone of the skull. It is one of the several oval or circular openings (foramina) in the base of the skull. The spinal cord, an extension of the medulla oblongata, passes through the foramen magnum as it exits the cranial cavity.
What is inferior anatomy?
Inferior or caudal – away from the head; lower (example, the foot is part of the inferior extremity). Lateral – away from the midline of the body (example, the little toe is located at the lateral side of the foot).
Which bone is most inferior?
The coccyx (cocs-ICKS), or tailbone, is the most inferior portion of the human vertebral column.
What bones can be identified by looking at the skull with an inferior view and the mandible removed How many are paired?
The paired bones are the maxilla, palatine, zygomatic, nasal, lacrimal, and inferior nasal conchae bones. The unpaired bones are the vomer and mandible bones.
What does inferior mean in medical terms?
Directional Terms Inferior or caudal – away from the head; lower (example, the foot is part of the inferior extremity). Lateral – away from the midline of the body (example, the little toe is located at the lateral side of the foot).
What is anterior skull?
Anterior View of Skull. The anterior skull consists of the facial bones and provides the bony support for the eyes and structures of the face. This view of the skull is dominated by the openings of the orbits and the nasal cavity. Also seen are the upper and lower jaws, with their respective teeth (Figure 2).
What is the name of the anterior bone of the skull?
Anatomy: Skull Anterior View. Summary: The skull (cranium) is divided into 2 main functional parts: neurocranium and viscerocranium. The major anterior skull bones include: Frontal bone, Mandible, Maxilla, Nasal bone, Parietal bone, Temporal bone, and Zygomatic bone .
What is the anatomy of the skull?
Anatomy of the skull. The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
What are the bones of the skull?
The human skull is generally considered to consist of twenty-two bones-eight cranial bones and fourteen facial skeleton bones. In the neurocranium these are the occipital bone, two temporal bones, two parietal bones, the sphenoid, ethmoid and frontal bones.
