  1. The sphenoid bone is the most complex bone of the human body.Because of its shape, it is also known 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.. The soft tissue structures such are the cranial nerves and parts of the brain are associated with this bone and have intense relations to it
  2. The ethmoid bone is a single, midline bone that forms the roof and lateral walls of the upper nasal cavity, the upper portion of the nasal septum, and contributes to the medial wall of the orbit (Figure 6.23). On the interior of the skull, the ethmoid also forms a portion of the floor of the anterior cranial cavity
  3. Within the ethmoid bone are small spaces called ethmoid air cells, which are located just behind the superior nasal conchae. The nasal septum consists of upper and lower/posterior portions
  4. The specific bones involved are the palatine process of the maxilla, and the horizontal plate of the palatine bone [7, 17]. The Roof: The relatively narrow roof is made us of the front-inferior part of the frontal bone, the two nasal bones, the cribriform plate of the ethmoid bone [15], as well as the sphenoid bone and ala of vomer [18]

Structure. The ethmoid bone is an anterior cranial bone located between the eyes. It contributes to the medial wall of the orbit, the nasal cavity, and the nasal septum. The ethmoid has three parts: cribriform plate, ethmoidal labyrinth, and perpendicular plate.The cribriform plate forms the roof of the nasal cavity,the ethmoidal labyrinth consists of a large mass on either side of the. Superior Border (Roof): The two nasal bones, the lower part of the frontal bone, the cribriform plate (of ethmoid bone), and the sphenoid bone [1, 10] make up the roof. Anterior Border (Lateral Wall): The lower parts of the nasal bones, the cartilage attached to them, the outer nose, and the nostrils are there in the front part of the nasal. Facial Bones Function. The facial bones have many functions, as each individual bone supports different areas of the face. Firstly, the facial bones protect the soft tissues that lie underneath, such as the mucous membranes and sensory cells of the nasal cavity, the oral cavity, the eyes, and - if the ethmoid is included - the pituitary. The function of compact bone is to help to keep the levels of these minerals at constant within the blood. The arteries and veins that run through the Haversian canals provide a means to transport the minerals to and from the compact bone. The minerals are deposited for storage within the lamellae when blood levels are high

Ethmoid definition, of or relating to a bone at the base of the cranium and the root of the nose, containing numerous perforations for the filaments of the olfactory nerve. See more Ethmoid: Paired anterior and middle draining into middle meatus (hiatus semilunaris and ethmoid bulla, respectively) and posterior draining into superior nasal meatus Sphenoidal: Paired sinuses, in sphenoid bone, draining into sphenoethmoidal reces These bones include the frontal, parietal, occipital, temporal, sphenoid and ethmoid bone. Review these bones and their purposes in this lesson. Anatomy and Physiology of the Mout The sphenoid is the most complex bone in the human skeleton.

Thus, the ethmoid bone is a useful indicator enabling us to analyse 150 species, and describe the distribution of OOS within the class Mammalia Caudal: The cribrifrom plate of the ethmoid bone. Ventral: Continuous with the nasopharynx. Dorsal: The maxilla and the palatine processes of the incisive bone. Rostrally, the median septum is a continuation of the ethmoid bone. The median septum is made up of hyaline cartilage, and divides the nasal cavity into left and right halves The Cribriform Plate of the ethmoid bone is located in the frontal bone and roofs in the nasal cavities. The ethmoid bone comprises a perpendicular plate and two ethmoid labyrinths that are attached to the Cribriform Plate. This perpendicular plate runs horizontally from the Cribriform Plate and attaches itself to the septal cartilage of the nose Articulations: the sphenoid bone can be seen articulated with other twelve bones which are, four singular bones namely, ethmoid, frontal, vomer and occipital, and four pairs of bones which are parietal bones, zygomatic bones, temporal bones and palatine bones. Sphenoid Bone Functions. The sphenoid bone mainly plays a key role in the development.

It also articulates with the ethmoid bone, the lacrimal bones and the sphenoid bone. Medical imaging of facial and mandibular fractures The contributions of the ethmoid bone and the vomer to the total bone surface area were inversely proportional; specimens with the largest ethmoid bones had the smallest vomers, and vice versa ethmoid. Which of the following is true of the nasal conchae? -The inferior portion of the sphenoid bone forms the superior nasal conchae. -The middle nasal conchae arises from the ethmoid bone. -All of the nasal conchae are part of the same bone. -The nasal conchae are located on the medial wall of the nasal cavity Ethmoid sinus comprises a group of ethmoidal air cells in the ethmoid bone, present between the nose and the eye sockets. Infection of these air cells by bacteria or virus is referred to as ethmoidal sinusitis. This article informs about its anatomy and disease conditions

The tubular sheaths of the olfactory nerves form a continuous tissue connection between the intracranial cerebrospinal fluid space and the lymph vessels of the nose. The sphenoid is an unpaired bone. The inferior oblique arises from the orbit floor near the orbital rim while the rectus muscles arise from the annulus of Zinn. [16] Orbital fractures are associated with many aesthetic defects. The disc between C3 and C4 is healthy and well hydrated and is designed to prevent bone-on-bone compression of the vertebrae. The C4-C5 intervertebral disc, however, is degenerated and almost flat. As a result, there is bone-on-bone compression of the uncinate processes, which has stimulated the formation of osteophytes (bone spurs)
