What does the infratemporal fossa contain?
What does the infratemporal fossa contain?
The infratemporal fossa serves as the passageway for many neurovascular structures. In addition to this, it contains superficial muscles like the inferior portion of the temporalis muscle, the lateral pterygoid muscle and the medial pterygoid muscle.
What goes through the Pterygopalatine fossa?
The pterygopalatine fossa is an important pathway for the spread of neoplastic and infectious processes: medially: communicates with the nasal cavity via the sphenopalatine foramen, which transmits the sphenopalatine artery, the nasopalatine nerve and the posterior superior nasal nerves.
Which of the following veins can be observed in the infratemporal fossa?
The internal jugular vein reaches the infratemporal fossa via the jugular foramen. Along with drainage from the inferior petrosal sinus, the internal jugular vein receives multiple tributaries from the face (transverse facial, lingual, retromandibular veins), head, and neck (external jugular vein).
Which ganglion is located within the infratemporal fossa?
The otic ganglion is a small parasympathetic ganglion located immediately below the foramen ovale in the infratemporal fossa and on the medial surface of the mandibular nerve.
What is foramen ovale skull?
Foramen ovale (plural: foramina ovalia) is an oval shaped opening in the middle cranial fossa located at the posterior base of the greater wing of the sphenoid bone, lateral to the lingula.
What passes through the foramen ovale?
The important structures which pass through it are the mandibular nerve, the accessory meningeal artery, the lesser superficial petrosal nerve and the emmissary vein [1]. This is the one of the important foramina which are situated at the transition zone between the intracranial and the extracranial structures [2].
What structures are in the pterygopalatine fossa?

- Foramen rotundum.
- Pterygoid canal.
- Palatovaginal canal.
- Inferior orbital fissure.
- Palatine canal.
- Sphenopalatine foramen.
What passes through pharyngeal canal?
The palatovaginal canal (also pharyngeal canal) is a canal between the sphenoid bone and the palatine bone that connects the nasopharynx with the pterygopalatine fossa….

Is the foramen ovale in the infratemporal fossa?
The infratemporal fossa is connected to other spaces in the skull. It is connected to the middle cranial fossa by the foramen ovale and the foramen spinosum. It is connected to the temporal fossa, which lies deep to zygomatic arch.
Which nerve passes through the infratemporal fossa?
mandibular nerve
The mandibular nerve enters the infratemporal fossa and passes through the foramen ovale in the sphenoid bone, and divides at that point into a smaller anterior and a larger posterior trunk.
What is fossa in anatomy?
Fossa – A shallow depression in the bone surface. Here it may receive another articulating bone or act to support brain structures. Examples include trochlear fossa, posterior, middle, and anterior cranial fossa.
What is Meckel’s cave?
Meckel’s cave is a dural recess in the posteromedial portion of the middle cranial fossa that acts as a conduit for the trigeminal nerve between the prepontine cistern and the cavernous sinus, and houses the Gasserian ganglion and proximal rootlets of the trigeminal nerve.
