What shape is the occipital bone quizlet?
The occipital bone, a saucer-shaped membrane bone situated at the back and lower part of the skull, is trapezoidal in shape and curved on itself. It is pierced by a large oval opening, the foramen magnum, through which the cranial cavity communicates with the vertebral canal.
What is the bone that makes up the lower portion of the nasal septum quizlet?
The ethmoid bone forms the inferior portion of the nasal septum. The ethmoid bone is part of the axial skeleton.
Which two facial bones contain alveoli?
Terms in this set (83) This is the name for the portion of the two maxillary bones and the mandible that contain the alveoli for the teeth. These features are found in both maxillary bones and the mandible.
What type of bone is the nasal bone?
oblong bonesGross Anatomy The nasal bones are two small, symmetrical oblong bones, each having two surfaces and four borders. Positioned in the midface, at their junction, they form the bridge of the nose superiorly and anchor the upper lateral nasal cartilages inferiorly.
What is the sphenoid bone?
The sphenoid is just one of the twenty-two bones that form the skull and essentially helps to connect the neurocranium to the facial skeleton. It is a single bone in the midline of the cranial cavity situated posterior to the frontal bone but anterior to the occipital.
Is the occipital bone?
The occipital bone (/ˌɒkˈsɪpɪtəl/) is a cranial dermal bone and the main bone of the occiput (back and lower part of the skull). It is trapezoidal in shape and curved on itself like a shallow dish. The occipital bone overlies the occipital lobes of the cerebrum….

Which scroll shaped bone is considered an individual facial bone?
It extends horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone, curled upon itself like a scroll, (turbinate meaning inverted cone). The inferior nasal conchae are considered a pair of facial bones.
What is the bone that makes up the lower portion of the nasal septum?
The vomer forms the inferior part of the nasal septum, with the superior part formed by the perpendicular plate of the ethmoid bone.
What bone forms part of nasal septum?
The nasal septum is formed by the perpendicular plate of the ethmoid bone and the vomer bone.
Which bone has the same flat shape of the cranium or head?
Parietal bones. This a pair of flat bones located on either side of your head, behind the frontal bone.
What two bones form the nasal septum?
The bony septum consists of the perpendicular plate of the ethmoid bone superiorly, extending to the cribriform plate, and the vomer inferiorly, which borders the choana.
What is the posterior border of the nasal cavity?
Posterior Border (Back Wall): The upper-back and sides are bordered with a number of cranial bones including the maxilla, ethmoid bone, palatine bone, sphenoid bone, lacrimal bone, as well as the inferior concha [1]. Floor: Apart from keeping the nasal cavity separated from the oral cavity,…
What is the shape of the nasal cavity?
Here are the two nasal cavities. The septum dividing them is a little off center, which is not unusual. The roof of each cavity, formed by the cribriform plate, is very narrow. The medial wall of each nasal cavity, formed by the septum, is smooth and featureless, so is the floor.
What is the bony opening for the nose?
The bony opening for the nose is called the piriform aperture. Inside it there are two nasal cavities, a right and a left, separated in the midline by the nasal septum. To get a better look inside we’ll divide the skull in the frontal plane along this line.
What is the structure of the nose bridge?
Two small nasal bones and extensions of the maxillae form the bridge of the nose, which is the bony portion. The remainder of the framework is cartilage and is the flexible portion. Connective tissue and skin cover the framework. Air enters the nasal cavity from the outside through two openings: the nostrils or external nares.
