Head Flashcards
Cone-shaped chambers immediately inferior to the anterior aspect of the cranial cavity, and the apex of each cone is directed posteromedially
Orbits
posterior openings of the nasal cavity
Choanae (posterior nasal apertures)
composed of a series of compartments, which are formed by bone and soft tissues
head
Largest compartment and contains the brain and associated membranes (meninges)
Cranial cavity
Walls, floors, and ceilings are predominantly composed of bone and cartilage
Nasal cavity
anterior openings to the nasal cavities
Nares (nostrils)
Inferior to the nasal cavities, and separated from them by the hard and soft palates
Oral cavity
Forms the floor of the oral cavity
soft tissues
anterior opening to the oral cavity
Oral fissure (mouth)
posterior opening to the oral cavity
Oropharyngeal isthmus
an area between the ramus of the mandible and the lateral plate of the pterygoid process just posterior to the upper jaw (maxilla)
Infratemporal fossa
the mandibular division of the trigeminal nerve [V3]
mandibular nerve
It is a conduit for one of the major cranial nerves- the mandibular nerve (the mandibular division of the trigeminal nerve [V3]), which passes between the cranial and oral cavities
Infratemporal fossa
The infratemporal fossa is the conduit for
the mandibular nerve (the mandibular division of the trigeminal nerve [V3]), which passes between the cranial and oral cavities.
The pterygopalatine fossa on each side is just posterior to the upper jaw. This communicates with the:
cranial cavity infratemporal fossa orbit nasal cavity oral cavity
Major structure passing the pterygopalatine fossa
(maxillary division of the trigeminal nerve) maxillary nerve [V2]
anterior aspect of the head
Face
contains a unique group of muscles that move the skin relative to underlying bone and control the anterior openings to the orbits and oral cavity
Face
covers the superior, posterior, and lateral regions of the head
Scalp
Seperates the oral cavity from the nasal cavity
Hard and soft palates
The infratemporal fossa is posterior to the
Upper maxilla
Passes between the cranial and oral cavities
Maxillary nerve
Located on on each side is just posterior to the upper jaw
Pterygopalatine fossa
Contains the eyes
Orbit
Upper parts of the respiratory tract and are between the orbits
Nasal cavity
