What is zygomatic arch process?


What is zygomatic arch process?

Zygomatic Arch Definition The extension of the temporal bone is known specifically as the zygomatic process, and attaches directly to the similarly shaped process on the zygomatic bone. The two extensions effectively make a tunnel of bone through which muscle and tendon can pass.

What are the processes of zygomatic bone?

Processes of the zygomatic bone The zygomatic bone itself has four processes, namely the frontosphenoidal, orbital, maxillary and temporal processes. The frontosphenoidal process is thick and serrated. The cranial suture between the frontal and zygomatic bone is found here.

What process of the zygomatic bone forms part of the zygomatic arch?

The temporal process of the zygomatic bone and the zygomatic process of the temporal bone fuse to form the zygomatic arch.

What does the zygomatic process articulate with?

The zygomatic bone articulates with the sphenoid bone, maxilla, frontal bone, and temporal bone to form the lateral wall of the floor of the orbit, part of the temporal and infratemporal fossa, and the prominence of the cheek.

Are there two zygomatic processes?

It is often referred to as the cheekbone, and it comprises the prominence just below the lateral side of the orbit. The zygomatic bone is nearly quadrangular in shape and it features three surfaces, five borders and two processes.

What structures contribute to the zygomatic arch quizlet?

(The zygomatic bones are known as the cheekbones. Together, the zygomatic bone and the temporal bone form the zygomatic arch.

What is zygomatic arch bones?

zygomatic arch, bridge of bone extending from the temporal bone at the side of the head around to the maxilla (upper jawbone) in front and including the zygomatic (cheek) bone as a major portion.

What bones form the zygomatic arch?

The cranial portion of the zygomatic arch is formed by the zygomatic bone, and the caudal portion is formed by the zygomatic process of the temporal bone. The zygomatic arch forms the ventral and lateral rim of the orbit.

What two bones and landmarks compose the zygomatic arch?

Which bones contain alveolar processes quizlet?

The alveolar process (/ˈælviːələr/) (alveolar bone) is the thickened ridge of bone that contains the tooth sockets (dental alveoli) on bones that hold teeth. In humans, the tooth-bearing bones are the maxillae and the mandible. having joints or jointed segments.

What is the frontal process of zygomatic bone?

Frontal process of zygomatic bone The frontal process features a bony tubercle on its orbital surface called the Whitnall’s tubercle, which serves as an attachment site for the lateral palpebral ligament, suspensory ligament of the eye, and the aponeurosis of levator palpebrae superioris muscle.

What are the two processes of the zygomatic arch?

Description. The zygomatic arch (cheek bone) is formed by the zygomatic process of temporal bone and the temporal process of the zygomatic bone, the two being united by an oblique suture (zygomaticotemporal suture).

How many processs are in the zygomatic bone?

Processes. Each zygomatic bone is diamond-shaped and composed of three processes with similarly named associated bony articulations: frontal, temporal, and maxillary. Each process of the zygomatic bone forms important structures of the skull.

Which bones contain alveolar processes?

The alveolar process, which is also called the alveolar bone, is the thick ridge of bone which contains the tooth sockets. The alveolar bone is located on the jaw bones which hold the teeth. In humans, these bones that contain the teeth are the maxilla and the mandible.

What is the alveolar process quizlet?

Is the zygomatic process part of the temporal bone?

The zygomatic process is a long arched process, projecting from the lower part of the squamous part of temporal bone.

Is the zygomatic a process?

Where is the zygomatic arch?

Which bones form a zygomatic arch cheekbone?

The facial area includes the zygomatic, or malar, bones (cheekbones), which join with the temporal and maxillary bones to form the zygomatic arch below the eye socket; the palatine bone; and the maxillary, or upper jaw, bones.
