Bones Flashcards
8 of these Ethmoid bone- not accessible Frontal Occiput Parietal (2) Sphenoid Temporal
Cranial Bones
There are 14 of these Inferior nasal concha (2) Lacrimal (2) Mandible-jawbone Maxilla (2) Nasal(2) Palatine(2) Vomer Zygomatic (2)
Facial Bones
Located at the posterior and nefarious aspects of the cranium
Extends superiorly from the external occipital protuberance and laterally to the mastoid process and temporal bones
Occiput
Bump of knowledge
Small superficial point located along the back of the head at the center of the Occiput
Lies between the attachment sites of both the trapezius muscles is the superior attachment for the ligamentum nuche
External Occipital Protuberance
Located along either side of the occipital protuberance faint sometimes bumpy ridges extends laterally in mastoid process
Attachment sites for the trapezius and splenius capitals muscles
Superior nuchal lines
Large rectangular top and sides of cranium
Positioned between frontal,occipital and temporal bones
Saucer shaped extend anteriorly to the level of the ear canal
Merge to form the Sagittal suture,
Parietal Bones
Three important bony landmarks
Mastoid Process
Styloid Process
Zygomatic Arch
Temporal Bone
large, superficial bump directly behind the earlobe. Attachment site for the scm and other muscles more larger in men than women
Mastoid Process
Cheekbone, formed by the temporal and zygomatic bones, attachment site for the masseter muscle
Zygomatic Arch
located behind the earlobe between the mastoid process and the posterior edge of the mandible.
Fanglike shape serves as an attachment site for several ligments and muscles deep not accessible
Styloid Process
located on the anterior aspect of the cranium, forms the forehead and upper rim of the eye sockets, articulates with the parietal bones
frontal bones
located inside the cranium and has major articulation with the fourteen bones of the skull located behind the eyeballs and superior to the zygomatic arches, shaped like a butterfly lateral portions called the greater wings
Sphenoid Bone
Includes the
Nasal Bones-located at the bridge of the nose
Zygomatic-known as the cheekbone forms anterior aspect of the zygomatic arch attachment of the masseter muscle
Maxilla-maxillary bones form the center of the face, inferior portion of the orbit of the eye, surface around the nose and upper jaw and upper row of teeth
Facial Bones
jaw, includes the base (jaw line), submandibular fossa (underside of the mandible and is an attachment site for the suprahyoid muscles), includes the angle, ramus, coronoid process (anteriorly to the condyle of the mandible
MANDIBLE
horseshaped , located superiorly to the thyroid cartilage
hyoid bone
