Extra Skeletal Lecture 31 01 2010 20 27 00 Anterior nasal spine projects off of the maxilla Inferior concha OWN BONE Middle concha ethmoid bone Superior concha don t worry about it cant see part of ethmoid Perpendicular plate of the ethmoid is part of the nasal septum Vomer part of nasal septum Holding ethmoid bone by crista galli upper projection of the perpendicular plate of the ethmoid Lateral sides of the ethmoid bone make up orbital Hard palate made up of horizontal plate of maxilla until 2 3 of way and then horizontal plate of palatine Greater and lesser palatine formena two holes in corner of hard palate Vertical perpendicular palate of the ethmoid Two opening on greater wing of sphenoid Foramen ovali is larger Foramen spinosum Suture seperates sphenoid from temporal bone Opening between styloid and mastoid process Stylo masto foramen Peterous portion of temporal below sphenoid and medial to temporal bone in posterior view round opening in petreous portion is carotid canal 2 foramen in temporal just below temporal bone is jugular foramen surrounded by petreous portion and occipital bone greater occipital protrusion bumps onback of the head greater foramen occipital condyle articulate with atlas hypoglossal canal interior near greater foramen only see the lesser wing of the sphenoid in anterior cranial fossa middle cranial fossa squamous portion of the temporal bone and connects to greater wing of the sphenoid foramen ovali and foramen spinosum superior orbital fissure inbetween wings of the sphenoid foramen rotundum above formane ovali petreous ridge separates middle from posterior cranial fossa body of sphenoid hypophysseal for pituitary gland cella churstka posterior cranial fossa temporal and occipital bone cerebellum sits in here cylvus where brain stem sits part of occipital bone internal auditorial acoustical canal jugular foramen just posterior to petreous infrorbital foramen smaller bone inferior orbital fissure in between greater wing of the sphenoid and the maxilla cervical bone transverse foramen holes anterior to transverse process large body pedicle atlas no body transverse foramen anterior and posterior arch superior articular process where is connects to occipital condyle o grooved flatter inferior articular process axis had a body with a dens short transverse process and transverse foramen articulates with c1 o on dens o on atricular processes two occipital processes inhibits us from turning our head back wards thoracic long spinous process o goes down at an oblique angle o notch goes into pedicle one above and one below make a foramen intervertebral foramen how nerves come out of vertebrae lamina connects spinous process to transverse process facets on body inferior and superior where ribs attach facet on transverse process where tubercles of ribs attach lumber thick body thick pedicle short transverse process spinous process looks like a square intervertebral discs cartilage between vertebrae most superior is c2 and c3 o cant have one between atlas and axis because dens is in the way most inferior is between l5 and s1 sacrum primary curvature of spine along with thoracic mandible mental foramen mandibular foramen humerus smooth part attaches to shoulder greater tuberacle rough for muscle attachments o lateral lesser tuberacle o medial to the greater tuberacle groove in between intertuberalan groove one big process don t know name olecerom process carpals know them proximal and distal schaffold not a good blood supply and bone dies quickly 1st digit and metacarpal have a saddle joint o opposition one bone in phalanges is phalanx phalanges is plural o pointer middle ring and pinky have 3 phalinx o thumb has 2 femur head greater trochanter larger than a trochanter lesser trochanter two condyles on distal end o medial is way larger than lateral 31 01 2010 20 27 00 31 01 2010 20 27 00
