It somewhat resembles a bat with its wings extended, and is divided into a median portion or body, two great and two small wings extending outward from the sides of the body, and two pterygoid processes which project from it below.

The list of terms: Pars squamosa (facies cerebralis) – Squamous part (cerebral surface) Pars petrosa (pyramis) – Petrous part (pyramid) of temporal bone. Pars petrosa (processus mastoideus) – Petrous part (mastoid process) Ethmoid bone.

The two sinuses are separated by a septum which may or may not be in the midline.

1 Definition. The sphenoid bone is a skull bone, which is located at the skull base frontal to the two temporal bones and the occipital bone.From dorsal perspective, it has the form of a butterfly with the body (corpus ossis sphenoidalis), two wings (major and minor alae) radiating laterally, and the pterygoid processes radiating caudally.

By the way, it is the most fragile bone in our body — made almost entirely by thin bony lamellae. Usually, ethmoid isn't present in skulls available for learning in Anatomy … 2020-09-21 Basis cranii interna from the posterior margins of the small Os frontale (1), Os sphenoidale (2), Os wings of the sphenoid bone (Alae temporale (3), Os occipitale (4), Os minor ossis sphenoidalis) and the ethmoidale (5) anterior clinoid processes to the superior angles of the petrous parts of the temporal bones and the back of 1 Sella turcica (Dorsum sellae). The parasagittal cut of the skull, demonstrating the bones of the nasal septum relative to other walls of the nasal cavity.

2018-02-12 · The sphenoid bone, also known as Os sphenoidale, is a cranial bone, shaped like a butterfly or a wasp, which occupies most of the middle part of the skull’s base, making up the middle region of the cranial fossa. Crammed between a group of bones in the frontal part of the cranium, it becomes one of the 8 bones that form the cranium.

It somewhat resembles a bat with its wings extended, and is divided into a median portion or body, two great and two small wings extending outward from the sides of the body, and two pterygoid processes In short — We are building an evidence-based 3D model of the human body, create high-quality, interactive illustrations of the model, and share them here to provide a resource for teaching and explaining anatomy. Gross anatomy. Parts of the sphenoid bone include: body. jugum sphenoideum; greater wing; lesser wing; pterygoid process and plates; Articulations. The sphenoid bone articulates with twelve bones: unpaired bones include: frontal, ethmoid, vomer, and occipital; paired bones include: zygomatic, parietal, temporal, and palatine. Fissures, foramina, grooves and canals processus pterygoideus ossis sphenoidalis.

Viewed anteriorly, the greater wings of the sphenoid resemble wings of a bird while the pterygoid processes resemble the extended limbs (Fig. 1). Gross anatomy.

The sphenoid sinus is one of the four paired paranasal sinuses that is contained within the body of the sphenoid bone.The sphenoid sinuses vary in size and shape, and owing to the lateral displacement of the intervening septum, which may insert on the carotid canal, they are rarely symmetrical.

The parasagittal cut of the skull, demonstrating the bones of the nasal septum relative to other walls of the nasal cavity. The perpendicular plate of ethmoid and vomer is the primary but not sole bony components of the nasal cavity's medial wall. The list of terms: Septum nasi osseum. – Bony nasal septum. The sphenoid bone is a large, complex, unpaired bone forming the central parts of the anterior and central skull base.
