Lab Exercise: The Axial Skeleton Skull Virtual Lab As a note: I did not have a picture that showed the following structures well. You are still responsible for them: Sagittal suture Stylomastoid foramen Mandibular fossa Middle nasal conchae Incisive fossa Mandibular notch Mandibular foramen The sinuses

Frontal bone Glabella Supraorbital foramen Nasal bones Lacrimal bone Inferior nasal conchae Zygomatic bone Vomer Maxilla Mandible

Infraorbital foramen Alveolar margin of the maxilla Mental foramen Alveolar margin of the mandible Mandibular symphysis

Frontal process of the maxilla Frontal process of the zygomatic Zygomatic process of the frontal bone Perpendicular plate (ethmoid bone) Zygomatic process of the maxilla

Orbital surface of the frontal bone Orbital surface of the sphenoid bone Orbital surface of the ethmoid bone Orbital surface of the zygomatic bone Orbital surface of the maxilla

Optic canal Superior orbital fissure Inferior orbital fissure

Coronal suture Squamous suture Coronoid process Mandibular condyle Lambdoid suture Styloid process Mastoid process Occipitomastoid suture

Squamous region of temporal bone External acoustic (auditory) meatus Tympanic region Mastoid region Body of mandible Mandibular angle Mandibular ramus (Ramus of Mandible)

Zygomatic process of the frontal bone Frontal process of the zygomatic bone Temporal process of the zygomatic bone Zygomatic process of the temporal bone

Cribriform plate with olfactory foramina Crista galli Lesser wing of the sphenoid Hypophyseal fossa Greater wing of the sphenoid Dorsum sellae Together these make the sella turcica

Foramen lacerum Jugular foramen Foramen magnum Optic Canal Foramen rotundum Foramen ovale Foramen spinosum Jugular foramen Internal acoustic (auditory) meatus Hypoglossal canal Foramen magnum

Palatine process of maxilla Palatine bone Foramen lacerum Petrous region of the temporal bone Carotid canal Jugular foramen Occipital condyle External occipital protuberance

Now quiz yourself!

Together these make?
