Sphenoidal Lingula

	Sphenoidal Lingula Along the posterior part of the lateral margin of the carotid groove of the sphenoid bone, in the angle between the body and great wing The greater wing of the sphenoid bone, or alisphenoid, is a bony process of the sphenoid bone; there is one on each side, extending from the side of the body of the sphenoid and curving upward, laterally, and backward.

picture info	Sphenoid Bone The sphenoid bone is an unpaired bone of the neurocranium. It is situated in the middle of the skull towards the front, in front of the basilar part of occipital bone, basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit (anatomy), orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended. Structure It is divided into the following parts: * a median portion, known as the body of sphenoid bone, containing the sella turcica, which houses the pituitary gland as well as the paired paranasal sinuses, the sphenoidal sinuses * two Greater wing of sphenoid bone, greater wings on the lateral side of the body and two Lesser wing of sphenoid bone, lesser wings from the anterior side. * Pterygoid processes of the sphenoides, directed downwards from the junction of the body and the greater wings. Two sphenoidal conchae are situated at the anterior and inferior part of the body. Intrinsic ligaments of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Base Of The Skull The base of skull, also known as the cranial base or the cranial floor, is the most inferior area of the skull. It is composed of the endocranium and the lower parts of the calvaria. Structure Structures found at the base of the skull are for example: Bones There are five bones that make up the base of the skull: Ethmoid bone Sphenoid bone * Occipital bone Frontal bone Temporal bone Sinuses Occipital sinus Superior sagittal sinus Superior petrosal sinus Foramina of the skull Foramen cecum Optic foramen Foramen lacerum Foramen rotundum Foramen magnum * Foramen ovale Jugular foramen Internal auditory meatus Mastoid foramen Sphenoidal emissary foramen Foramen spinosum Sutures Frontoethmoidal suture Sphenofrontal suture Sphenopetrosal suture Sphenoethmoidal suture Petrosquamous suture Sphenosquamosal suture Other Sphenoidal lingula Subarcuate fossa Dorsum sellae Jugular process Petro-occipital fissure Condylar canal Jugular tubercle * ...

	Foramen Lacerum The foramen lacerum ( la, lacerated piercing) is a triangular hole in the base of skull. It is located between the sphenoid bone, the apex of the petrous part of the temporal bone, and the basilar part of the occipital bone. Structure The foramen lacerum ( la, lacerated piercing) is a triangular hole in the base of skull. It is located between 3 bones: * the sphenoid bone, forming the anterior border. * the apex of petrous part of the temporal bone, forming the posterolateral border. * the basilar part of occipital bone, forming the posteromedial border. It is the junction point of 3 sutures of the skull: * the petroclival (petrooccipital) suture. * the sphenopetrosal suture. * the sphenooccipital suture. It is situated anteromedial to the carotid canal. Development The foramen lacerum fills with cartilage after birth. Function The foramen lacerum transmits many structures, including: * the artery of the pterygoid canal. * the recurrent artery of the foramen laceru ...

	Carotid Groove The carotid groove is an anatomical groove in the sphenoid bone located above the attachment of each great wing of the sphenoid bone. The groove is curved like the italic letter f, and lodges the internal carotid artery and the cavernous sinus The cavernous sinus within the human head is one of the dural venous sinuses creating a cavity called the lateral sellar compartment bordered by the temporal bone of the skull and the sphenoid bone, lateral to the sella turcica.

	Great Wings Of The Sphenoid The greater wing of the sphenoid bone, or alisphenoid, is a bony process of the sphenoid bone; there is one on each side, extending from the side of the body of the sphenoid and curving upward, laterally, and backward. Structure The greater wings of the sphenoid are two strong processes of bone, which arise from the sides of the body, and are curved upward, laterally, and backward; the posterior part of each projects as a triangular process that fits into the angle between the squamous and the petrous part of the temporal bone and presents at its apex a downward-directed process, the spine of sphenoid bone. Cerebral surface The superior or cerebral surface of each greater wing ig. 1forms part of the middle cranial fossa; it is deeply concave, and presents depressions for the convolutions of the temporal lobe of the brain. It has a number of foramina (holes) in it: * The foramen rotundum is a circular aperture at its anterior and medial part; it transmits the maxillary nerve. ...
