Where is the pterygoid canal?
sphenoid bone
The pterygoid canal, also known as the Vidian canal, is a foramen in the base of skull, located in the pterygoid process of the sphenoid bone, superior to the pterygoid plates, and inferomedial to the foramen rotundum.
What goes thru foramen rotundum?
The Maxillary Nerve
The Maxillary Nerve (V2) The maxillary nerve (V2) passes through the foramen rotundum and into the infraorbital canal, where, at the pterygopalatine fossa, it branches into the pterygopalatine ganglion, with parasympathetic and sensory branches to the paranasal sinuses.
Where is the foramen rotundum located?
sphenoid
The foramen rotundum is located at the base of the greater wing of the sphenoid, inferior to the superior orbital fissure. It provides a connection between the middle cranial fossa and the pterygopalatine fossa.
What is a pterygoid canal?
The pterygoid canal, also known as the Vidian canal, is a foramen in the base of skull, located in the pterygoid process of the sphenoid bone, superior to the pterygoid plates, and inferomedial to the foramen rotundum.
What are Pterygoids?
The pterygoid muscles are two of the four muscles of mastication, located in the infratemporal fossa of the skull. These muscles are: lateral pterygoid and medial pterygoid. The primary function of the pterygoid muscles is to produce movements of the mandible at the temporomandibular joint.
What artery goes through the foramen rotundum?
However, the artery of foramen rotundum anastomosed with the cavernous ICA and supplied the collateral flow (figure 1). (A) Cerebral angiography showing the complete occlusion of the left internal carotid artery (ICA) at the cervical segment (arrow) and the artery of foramen rotundum (arrowhead).
What passes through Pterygoid Canal?
Anatomical terms of neuroanatomy The nerve of the pterygoid canal (Vidian nerve) is formed by the junction of the greater petrosal nerve and deep petrosal nerve, which passes from the foramen lacerum to the pterygopalatine fossa through the pterygoid canal.
How is pterygoid canal formed?
Structure. The nerve of the pterygoid canal forms from the junction of the greater petrosal nerve and the deep petrosal nerve within the foreamen lacerum. This combined nerve exits the foramen lacerum and travels to the pterygopalatine fossa through the pterygoid canal in the sphenoid.
What is Pterygoid Hamulus?
The pterygoid hamulus is a hook-shaped bony process located bilaterally on each medial pterygoid plate of the sphenoid bone, posterior and medial to each maxillary tuberosity. These processes project downward and anterolaterally; serve as attachment for ligaments and a network of muscles.
Is pterygoid a skull bone?
The pterygoid is a paired bone forming part of the palate of many vertebrates, behind the palatine bones. It is a flat and thin lamina, united to the medial side of the pterygoid process of the sphenoid bone, and to the perpendicular lamina of the palatine bone.
What is the pterygoid canal?
The pterygoid canal (also vidian canal) is a passage in the skull leading from just anterior to the foramen lacerum in the middle cranial fossa to the pterygopalatine fossa.
What passes through the medial pterygoid plate?
The pterygoid canal runs through the medial pterygoid plate of the sphenoid bone to the back wall of the pterygopalatine fossa . It transmits the nerve of pterygoid canal, (Vidian nerve), the artery of the pterygoid canal (Vidian artery), and the vein of the pterygoid canal (Vidian vein). Medial wall of left orbit.
Where does the vidian nerve join the pterygopalatine ganglion?
The vidian nerve joins the posterior part of the pterygopalatine ganglion. It runs through the vidian (pterygoid) canal, from which it takes its name, and forms a carotid branch and a cranial branch.
