The temporal bones are overlaid by the sides of the head known as the temples, and house the structures of the ears. The lower seven cranial nerves and the major vessels to and from the brain traverse the temporal bone.
What bones make up temples?
The temple is a latch where four skull bones fuse: the frontal, parietal, temporal, and sphenoid.
Which bone forms the temple area of the head?
The temporal bone
The temporal bone is subdivided into several regions (Figure 6.19). The flattened, upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch.
What does the temporal bone consist of?
The temporal bone is composed of several parts, these being the squamous part, the zygomatic process, the petromastoid part, the tympanic part, the styloid process. All of the constitutive parts of the temporal bone will be explained through this article.
What is the name of the bone that makes up most of the posterior surface of the orbit?
*What is the name of the bone that makes up most of the posterior surface of the orbit? the sphenoid.
Why is temporal bone named temporal bone?
Etymology. Its exact etymology is unknown. It is thought to be from the Old French temporal meaning “earthly,” which is directly from the Latin tempus meaning “time, proper time or season.” Temporal bones are situated on the sides of the skull, where grey hairs usually appear early on.
What type of bone is temporal bone?
This a pair of flat bones located on either side of your head, behind the frontal bone. Temporal bones. This is a pair of irregular bones located under each of the parietal bones.
Where is the temporal bone located?
the skull
The temporal bones are located on the sides and base of the skull. The temporal bones are paired bones that help make up the sides and base of the skull (cranium).
What is frontal bone?
Frontal bone: The large bone that makes up the forehead and supplies the upper edge and roof of the orbit (eye socket). The frontal bone articulates (comes together) with a number of other bones including the parietal, nasal, ethmoid, maxillary, and zygomatic bones.
Where is the ethmoid bone?
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.
What is the zygomatic bone?
The zygomatic bone (or zygoma) is a paired, irregular bone that defines the anterior and lateral portions of the face. The zygomatic complex is involved in the protection of the contents of the orbit and the contour of the face and cheeks.[1]
Where is the mastoid bone?
The mastoid is located just behind the ear. Mastoiditis is an infection of the bony air cells in the mastoid bone, located just behind the ear. It is rarely seen today because of the use of antibiotics to treat ear infections.
Is the mastoid bone part of the skull?
The mastoid part of the temporal bone is the posterior (back) part of the temporal bone, one of the bones of the skull. Its rough surface gives attachment to various muscles (via tendons) and it has openings for blood vessels. From its borders, the mastoid part articulates with two other bones.
Where is sphenoid bone?
skull
The sphenoid bone is one of the most complex bones of the human body. Due to its shape, it is also referred to as the ‘wasp bone’. It makes up most of the middle part of the base of the skull and contributes to the floor of the middle cranial fossa of the skull.
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.
Why is sphenoid bone called the Keystone?
A prominent, irregular, wedge-shaped bone at the base of the skull. The sphenoid bone has been called the “keystone” of the cranial floor since it is in contact with all of the other cranial bones.
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.
What is a maxilla?
The maxilla is the bone that forms your upper jaw. The right and left halves of the maxilla are irregularly shaped bones that fuse together in the middle of the skull, below the nose, in an area known as the intermaxillary suture. The maxilla is a major bone of the face.
Why is my temporal bone sore?
What are the causes & diagnosis of Temporalis Tendonitis? stress, tooth grinding, direct trauma to the Temporalis muscle, excessive gum chewing. In rare cases a condition called Coronoid Process Hyperplasia may be the cause of Temporal Tendinitis.
What is the name of the part of the temporal bone that houses the organs of hearing and equilibrium?
inner ear, also called labyrinth of the ear, part of the ear that contains organs of the senses of hearing and equilibrium. The bony labyrinth, a cavity in the temporal bone, is divided into three sections: the vestibule, the semicircular canals, and the cochlea.
Is the temporal bone a facial bone?
The bones that make up the neurocranium are the singular occipital, frontal, sphenoid, and ethmoid bones, and the paired temporal and parietal bones. The neurocranium is, therefore, composed of eight bones. As we have already seen, the facial bones sometimes include the sphenoid and ethmoid bones, and sometimes not.
