The periorbita is the area around the orbit. Sometimes it refers specifically to the layer of tissue surrounding the orbit that consists of periosteum . [ 1 ] [ 2 ] However, it may refer to anything that is around the orbit, such as in periorbital cellulitis .
The periorbital spaces; Since the hyoid bone is the most important anatomic structure in the neck that limits the spread of infection, the spaces can be classified according to their relation to the hyoid bone: [5] Suprahyoid (above the hyoid) Infrahyoid (below the hyoid) Fascial spaces traversing the length of the neck
The lateral wall is formed by the frontal process of zygomatic and more posteriorly by the orbital plate of the greater wing of sphenoid. The bones meet at the zygomaticosphenoid suture. The lateral wall is the thickest wall of the orbit, important because it is the most exposed surface, highly vulnerable to blunt force trauma.
The Orbital Fascia forms the periosteum of the orbit.. It is loosely connected to the bones and can be readily separated from them. Behind, it is united with the dura mater by processes which pass through the optic foramen and superior orbital fissure, and with the sheath of the optic nerve.
The trunk of the body contains, from superior to inferior, the thoracic region encompassing the chest [1] the mammary region encompassing each breast; the sternal region encompassing the sternum; the abdominal region encompassing the stomach area; the umbilical region is located around the navel; the coxal region encompassing the lateral (side ...
The human skull has numerous openings , through which cranial nerves, arteries, veins, and other structures pass. These foramina vary in size and number, with age. These foramina vary in size and number, with age.
The discovery of human bone fragments sent the researchers digging through the material excavated about nine decades ago — in which they found additional skeleton fragments.
The brow ridges are often not well expressed in human females, as pictured above in a female skull, and are most easily seen in profile. The brow ridge, or supraorbital ridge known as superciliary arch in medicine, is a bony ridge located above the eye sockets of all primates and some other animals.
