Front View of Skull	This page has been accessed times since 9 November 2001. 29 October 1992, rvsd 20 Sept 94, 12 Sept 95, 24 Oct 96, 22 Sept 97, 20 Sept 99, 19 Sept 00	View of Floor of Cranium

See Fundamentals of Anatomy and Physiology , Martini, 9^thEd, pp. 200-216 and
The Anatomy Coloring Book, Kapit and Elson 3rd, pp. 24-26.

Illustrate two views of the skull:

I. the floor of the cranium. (Martini's 9th, p. 203). (Note the eight bones which form the floor: frontal, ethmoid, sphenoid, two temporals, two parietals and the occipital)

II. the right-front side (3/4 view)

Label all bones with their listed features. Use the illustrations in Martini to aid in locating the bones and their features.

Here is an index page to many skull bone pictures not included on this page.
Here are overall views of the skull:

I. DISARTICULATED BONES OF THE SKULL

	CRANIAL BONES:
	FRONTAL (Contributes to orbit) supraorbital foramen glabella supraorbital (superciliary) ridge Sutures in the calvarium coronal sagittal
	SPHENOID (Contributes to orbit) greater wings lesser wings optic foramina superior orbital fissure (CN III, IV, V¹, VI)
	ETHMOID (Contributes to orbit) middle nasal concha Here are alternative views of the ethmoid: inferior view superior view Here is a (spooky) view up the nose showing the perpendicular plate, the cribriform plate and the middle nasal concha.
	FACIAL BONES:
	TEMPORAL squamous portion: zygomatic process
	ZYGOMATIC (Contributes to orbit)
	LACRIMAL (Contributes to orbit)
	PALATINE (Contributes to orbit) orbital surface
	MAXILLA (Contributes to orbit) frontal process (to frontal bone) zygomatic process infraorbital foramen alveolar margin maxillary sinus anterior nasal spine
	MANDIBLE mandibular angle mandibular notch coronoid process mandibular condyle alveolar margin mandibular foramen mental foramen
	VOMER
	INFERIOR NASAL CONCHA Also known as the turbinate This view is into the nasal cavity, the two lateral curved bones are the inferior nasal conchae.
	NASAL

II. DISARTICULATED BONES OF THE CRANIAL FLOOR

	FRONTAL
	PARIETAL venous sinuses
	TEMPORAL squamous portion petrous portion internal acoustic meatus (CN VIII) carotid canal Jugular foramen (CN IX, X, XI) (between temporal & occipital)
	ETHMOID crista galli (attaches to dura mater) cribriform plate (CN I)
	SPHENOID sella turcica greater wings lesser wings optic foramina (CN II) foramen rotundum (anterior, CN V² ) foramen ovale (lateral, CN V³ )
	OCCIPITAL foramen magnum basioccipital hypoglossal canal (CN XII)
