Anatomy of the Head & Neck - Chap. 3 Skeletal system
Tuberosity
A large, often rough prominence -Typically attachment areas for muscles or tendons
Crest
A prominent, often roughened border or ridge
Head
A rounded surface projecting from a bone by a neck
Meatus
A type of canal in bone
Spine
An abrupt prominence of the the bone that may be a blunt or sharply pointed projection
Articulation
Area of the skeleton where the bones are joined
Fossa
Depression on a bony surface
Process
General term for any prominence on a bony surface
Cornu
Hornlike prominence (only on hyoid)
Notch
Indentation at the edge of a bone
Canal
Longer, narrow, tubelike opening in bone
Fissure
Narrow, cleftlike opening in bone
Cranial Bones
Occipital Frontal Parietal Temporal Sphenoid Ethmoid
Condyle
Oval bony prominence, usually at articulations
Arch
Prominent bridgelike bony structures
Bones of the orbit - According to instructor
Rim = Frontal, maxillary, & zygomatic bones Floor/Base (Inside) = Sphenoid, ethmoid, & lacrimal bones
Tubercle or eminence
Rounded elevation on the bony surface
Sulcus
Shallow depression or groove, such as that on a bony surface
Foramen
Short, windowlike opening in bone
Line
Straight, small ridge
Lambdoidal suture
Suture between occipital bone & paired parietal bones
Coronal suture
Suture extending between the frontal & parietal bones
Sagittal suture
Suture extending from the front to the back of the skull, between the parietal bones
Suture
Union of bone joined by fibrous tissue (generally immovable)
Facial bones
Vomer Lacrimal bones Nasal bones Inferior nasal conchae Zygomatic bones Maxillary bones Mandible
