- Making the world better, one answer at a time. The zygomatic arch supports the main jaw muscle, the masseter, which is necessary both for biting and chewing food and for speech. Several other facial muscles attach to the zygomatic bone, as well.he zygomatic process is a connecting point where muscles and  ligaments of the jaw, neck, and face connect. The second function  is that of protection, of the eyes and mout … h.

Zygomatic bone Zygomatic bone. Zygomatic bone, also called cheekbone, or malar bone, diamond-shaped bone below and lateral to the orbit, or eye socket, at the widest part of the cheek. It adjoins the frontal bone at the outer edge of the orbit and the sphenoid and maxilla within the orbit.

Zygomaticus Major Summary Information: Zygomaticus Major. Zygomaticus Major: The zygomaticus major is a paired muscle located in the face in the cheek area. The zygomaticus major originates on the zygomatic bone and inserts on the modiolus of the mouth. The zygomaticus major lifts and pulls back the mouth in the smiling expression. It is innervated by the facial nerve.

Articular processes The articular processes or zygapophyses (Greek ζυγον =  yoke  (because it links two vertebrae) + απο = away + φυσις =  process ) of a vertebra, are projections of the vertebra that serve the purpose of fitting with an adjacent vertebra. The actual region of contact is called the articular facet. Articular processes spring from the junctions of the pedicles and laminae, laminæ and there are two right and, left and two superior and. inferior

What is a Zygote? What is a zygote? Time factor plays an important role in the formation of embryo or the zygote. A zygote is formed when sperm and the egg meet. Both the egg and sperm are haploid cells which mean that both of them comprise of half number of chromosomes as compared to the measure present in their parents. When these two haploid cells meet, they form a diploid zygote consisting complete set of chromosomes.

- The third bone (G in fig. 1) of the eye socket is counted the first [ os zygomaticum ] of the upper maxilla because it makes up the entire outer angle of the eye socket and half of its lower circumference, the remainder of which (L in fig.) is in its inner angle towards the front near its edge; it is the second of the maxillary bones. The sixth (O in figs. 1 and 2) [ lamina orbitalis ossis ethmoidalis ] of the bones of the eye socket lies in its inner side; located behind the bone just mentioned, we consider it the third of the maxillary bones.

Zygoma The term zygoma generally refers to the zygomatic bone, a bone of the human skull commonly referred to as the cheekbone or malar bone, but it may also refer to: 1  The zygomatic arch, a structure in the human skull formed primarily by parts of the zygomatic bone and the temporal bone. The zygomatic process, a bony protrusion of the human skull, mostly composed of the zygomatic bone but also contributed to by the frontal bone, temporal bone, and maxilla.

Skull The maxilla is the fusion of two bones and forms the upper jaw. The maxilla attaches to the zygomatic or cheek bones. The maxilla holds the upper teeth. The mandible is also known as the lower jaw. It holds the lower teeth. The mandible is connected to the upper part of the skull by two jaw joints.

5b. 4. The Zygomatic Bone FIG. 164 Left zygomatic bone in situ. The zygomatic bone is small and quadrangular, and is situated at the upper and lateral part of the face: it forms the prominence of the cheek, part of the lateral wall and floor of the orbit, and parts of the temporal and infratemporal fossae (Fossæ. fig. 164all describes it as being ossified from one center which appears just beneath and to the lateral side of the orbit. After birth, the bone is sometimes divided by a horizontal suture into an upper larger, and a lower smaller division. In some quadrumana the zygomatic bone consists of two parts, an orbital and a malar.

Contents: Gamete vs Zygote Zygote is the diploid cell that results from the fertilization between an egg and a sperm. In mammals, the sperm (male gamete) fertilizes the egg (ovum, the female gamete) and the fertilized egg is called a zygote.

The zygomaticus muscles make it possible for you to speak, chew and use your face to express emotions. You can injure these muscles by overuse or trauma.Because they are connected to the eye socket and the jawbone, injuries, irritation or disease in these areas can affect the zygomaticus as well.Some types of zygomaticus pain can heal with rest, but chronic pain may indicate a serious condition.ygomaticus pain can radiate into the eye area.

Facet joint The facet joints, (or zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae.There are two facet joints in each spinal motion segment and each facet joint is innervated by the recurrent meningeal nerves.The biomechanical function of each pair of facet joints is to guide and limit movement of the spinal motion segment.acet joint arthritis [edit]. In large part due to the mechanical nature of their function, all joints undergo degenerative changes with the wear and tear of age. This is particularly true for joints in the spine, and the facet joint in particular.

Muscles of the Head The origin is the zygomatic bone (the cheek bone!) and it inserts into the skin and muscle at the corner of the mouth so when it contracts it is what literally lifts the corners of your mouth to help you smile. Or in other words it lifts the corners of your mouth superiorly and posteriorly.

- The mandible is a U-shaped bone. It is the only mobile bone of the facial skeleton, and, since it houses the lower teeth, its motion is essential for mastication. It is formed by intramembranous ossification. The mandible is composed of 2 hemimandibles joined at the midline by a vertical symphysis.

- Also known as zygapophyseal or apopphyseal joint, is a synovial joint between the superior articular process of one vertebra and the inferior articular process of the vertebra directly above it. There are two facet joints in each spinal motion segment.

Maxilla These include the zygomatic, frontal, palatine, and alveolar processes of the maxilla. They also contain the infraorbital foramen, an opening in the bone just below the eye sockets, and the maxillary sinus, which helps to protect important facial structures during an accidental trauma, like the crumple zone of a car.axilla. The maxilla forms the upper jaw by fusing together two irregularly-shaped bones along the median palatine suture, located at the midline of the roof of the mouth.

Zygomatic Complex Facial Fractures Attempts to treat facial fractures were recorded in the 25-30 centuries BC. The Smith Papyrus is likely the first document in which treatment of several types of zygomatic fractures are described. In 1751, du Verney described the anatomy, type of fractures observed, and approach to reduction in two cases.

Zygote A zygote (from Greek ζυγωτός zygōtos joined or yoked, from ζυγοῦν zygoun to join or to yoke), is an eukaryotic cell formed by a fertilization event between two gametes. The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information necessary to form a new individual.

What is Sphenoid Bone? The sphenoid bone – Anatomy and Functions. Functions: One of the main functions of the sphenoid bone is that it helps in the development of the essential anatomical structures and formations of the skull.he sphenoid bone is located towards the front in the middle part of the skull, anterior of the temporal bone and near the bottom section of the occipital bone. It forms the cranium’s base, just posterior to the orbitals.
