Where is the cranial bone located?
skull
What are cranial bones? Your skull provides structure to your head and face while also protecting your brain. The bones in your skull can be divided into the cranial bones, which form your cranium, and facial bones, which make up your face.
Which of the following cranial bones is the site of the external acoustic meatus?
The tympanic part of the temporal bone is a curved plate immediately below the origin of the zygomatic process. Its concave posterior surface forms the anterior wall, floor and part of the posterior wall of the external acoustic meatus. The external acoustic opening is clearly visible on this part.
What bone is posterior bones of the hard palate?
The Axial Skeleton
| A | B |
|---|---|
| Palatine | posterior bones of the hard palate |
| Parietal | much of the lateral and superior cranium |
| Sphenoid | single, irregular, bat-shaped bone forming part of the cranial floor |
| Lacrimal | tiny bones bearing tear ducts |
Where are the palatine bones?
The palatine bones contribute to the posterior part of the roof of the mouth and floor and lateral walls of the nose, the medial wall of the maxillary sinuses and the orbital floors. Each bone (Fig. 5-66) consists of horizontal and perpendicular plates (laminae) set at right angles to each other.
What is vomer bone?
The vomer is a small, thin, plow-shaped, midline bone that occupies and divides the nasal cavity. It articulates inferiorly on the midline with the maxillae and the palatines, superiorly with the sphenoid via its wings, and anterosuperiorly with the ethmoid.
Which are the cranial bones?
Cranial Bones
- Parietal (2)
- Temporal (2)
- Frontal (1)
- Occipital (1)
- Ethmoid (1)
- Sphenoid (1)
Which of the skull bones are cranial bones?
The eight cranial bones are the bones surrounding the brain. They include the frontal bone, parietal bones (2), temporal bones (2), occipital bone, sphenoid bone, and ethmoid bone.
Where is the ethmoid bone located?
The ethmoid bone is an unpaired cranial bone that is a significant component of the upper nasal cavity and the nasal septum. The ethmoid bone also constitutes the medial orbit wall.
Why is it called the palatine bone?
In anatomy, the palatine bones (/ˈpælətaɪn/) are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat. Together with the maxillae, they comprise the hard palate. (Palate is derived from the Latin palatum.) Sagittal section of skull.
Where is palatine and maxilla bone?
The location of the palatine bone is best understood through its borders and articulations. Its horizontal plate is just behind the maxilla bone of the upper jaw, while lying in front of the soft palate (the soft tissue at the roof of the mouth).
