The pterygopalatine fossa (PPF) is a small, clinically inaccessible, fat-filled space located in the in the deep face It is the major neurovascular intersection between the oral cavity, nasal cavity, nasopharynx, orbit, masticatory space, and middle cranial fossa.

What is found in the pterygopalatine fossa?

in the pterygopalatine fossa, maxillary nerve Many branches arise, including the infraorbital, zygomatic, nasopalatine, superior alveolar, pharyngeal, and greater and lesser palatine nerves. …these nerves suspend the ganglion in the pterygopalatine fossa.

How many pterygopalatine fossa are there?

Anatomical Terms for Bones

In human anatomy, the sphenopalatine fossa is a fossa in the skull.human skull contains Two pterygopalatine fossa– One on the left and the other on the right.

In what canal the pterygopalatine fossa continues?

The circular foramen traversed by the maxillary nerve is located where the pterygoid process joins the fornix, immediately below it is wing tube, or Vidian nerve, for the transport of the homonymous nerve and arteries. The medial wall is formed by the vertical plate of the palatine bone.

What’s in the pterygoid fossa?

The lateral and medial wing plates (the pterygoid process of the sphenoid bone) bifurcate posteriorly and enclose a V-shaped fossa, the pterygoid fossa, between them.This nest faces backwards and contains pterygoid and tensor veli palatine.

What is the infratemporal fossa?

The infratemporal fossa is A complex space in the face located on the posterolateral side of the maxillary sinus, through which many important nerves and blood vessels pass. It is located below the base of the skull, between the lateral wall of the pharynx and the mandibular ramus.

Where are the wing protrusions?

per pterygoid item down from the junction of the body and the greater wing of the sphenoid bone And bifurcate into an inner wing plate and an outer wing plate. At the lower end of the medial wing are small hook-like projections, the wing shanks.

What are wing tubes?

Wing tubes, also known as wing tubes, are a hole in the base of the skulllocated in the pterygoid process of the sphenoid bone, above the wing plate, medial to the foramen.

Where is the middle cranial fossa?

middle cranial fossa is Butterfly-shaped depression at the base of the skull, narrower in the middle and wider in the horizontal direction. It houses the temporal lobe of the brain.

Which hole leads to the infratemporal fossa?

The infratemporal fossa forms important channels for many nerves originating in the cranial cavity (Figure 1.2): the mandibular nerve – a branch of the trigeminal nerve (CNV).it passes foramen ovaleproducing motor and sensory branches.

Where is the orbital fossa?

The pterygopalatine fossa is located in Lateral side of the nasal cavity behind the upper part of the maxillary sinus and below the orbital apex. The posterior wall of the maxilla is so thin that the maxillary artery, which runs in the pterygopalatine fossa, can be seen through the bone.

What does nest mean?

In anatomy, a fossa (/ˈfɒsə/; plural fossae (/ˈfɒsiː/ or /ˈfɒsaɪ/); from Latin « fossa », furrow or furrow) is sunken or dented, usually in bones, such as the pituitary fossa (a depression in the sphenoid bone). Some examples include: In the skull: the cranial fossa.

What is the zygomatic nerve?

The zygomatic nerve is a major branch of the maxillary branch of the trigeminal nerve. It should not be confused with the zygomatic branch of the facial nerve.

What are the boundaries of the temporal fossa?

The temporal fossa is bounded by several anatomical landmarks, anterior to the frontal process of the zygomatic bone, Above and behind the temporal linefollowed by the zygomatic arch.

What is a hiatus?

Hiatus (plural: foramina lacera) is A triangular opening in the middle cranial fossa, formed by the continuation of the petrosphenoid and petroclinical fissures. Therefore, it is the space between the bones, also known as sphenoid osteochondrosis, and not a true intraosseous foramen 2.
