What bones have a fossa?
The middle cranial fossa consists of three bones – the sphenoid bone and the two temporal bones.
What is a fossa bone marking?
Fossa – A shallow depression in the bone surface. Head – A rounded, prominent extension of bone that forms part of a joint. It is separated from the shaft of the bone by the neck.
What structure articulates with the mandibular fossa?
temporal bone
What bone makes up the mandibular fossa?
The mandibular fossa or glenoid fossa is the smooth concave articular surface formed by both the squamous and petrous parts of the temporal bone. It forms the superior articular part of the temporomandibular joint and lodges the condyle of mandible.
Where is the mandibular fossa found?
What does the Infratemporal fossa communicate with?
It is located deep to the masseter muscle and zygomatic arch (to which the masseter attaches). The fossa is closely associated with both the pterygopalatine fossa, via the pterygomaxillary fissure, and also communicates with the temporal fossa, which lies superiorly (figure 1.0).
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 nerve passes through the Infratemporal fossa?
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. The main trunk gives off two branches at this point.
What passes through Pterygopalatine fossa?
The inferior orbital fissure forms the superior boundary of the pterygopalatine fossa and communicates with the orbit. It is a space between the sphenoid and maxilla bones. The zygomatic branch of the maxillary nerve and the infraorbital artery and vein pass through the inferior orbital fissure.
What ganglion is located in 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. It is functionally associated with the glossopharyngeal nerve and innervates the parotid gland for salivation.
What does Pterygoid mean?
: of, relating to, or lying in the region of the inferior part of the sphenoid bone of the vertebrate skull. pterygoid. noun.
What is Pterygopalatine ganglion?
The pterygopalatine ganglion is one of four parasympathetic ganglia of the head and neck and largest of the peripheral parasympathetic ganglia. It receives parasympathetic fibers from the facial nerve.
What is the trigeminal ganglion?
The trigeminal ganglion is also called the Gasserian ganglion, semilunar ganglion, or Gasser’s ganglion. It is part of the trigeminal nerve, which gathers sensory stimuli from the head and face and provides nerve stimulation to the muscles that control chewing. (
