|
Maxillary Bones (Left and Right Maxilla). This is where the maxillary sinuses are found |
|
|
Nasal Bones (Left and Right Nasal Bone) |
|
|
Frontal Bone. This is where the frontal sinus is found |
|
|
Mandible. This is the only mobile skull bone |
|
|
Zygomatic Bone (Right) |
|
|
Temporal Bone (Right). The external acoustic meatus, zygomatic process, mastoid process, and styloid process are all found here. |
|
|
Parietal Bone (Right) |
|
|
Cribriform Plate of the Ethmoid Bone. The part that sticks up like a sail is called the Crista Galli. This is where the olfactory nerves enter the nasal sinuses |
|
|
Internal Acoustic Meatus. This is the only opening found on the inside of the temporal bone. |
|
|
Sella Turcica. This is where the pituitary gland sits |
|
|
Temporal Process of the Zygomatic Bone |
|
|
Mandibular Condyle. This articulates with the temporal process at the glenoid fossa of the temporomandibular joint (TMJ) |
|
|
Coronoid Process |
|
|
Ethmoid Bone. Ethmoid Sinuses found here |
|
Name the Opening |
Foramen Magnum. This is where the spinal cord exits the skull and enters the spinal column |
|
|
Occipital Condyle (Left). These articulate with the C1 (atlas) and allow you to look up and down. |
|
|
Mastoid Process (Left). Point of insertion for the sternocleidomastoid muscle |
|
|
Hyoid Bone. Supports the tongue |
|
|
C1 (Atlas). Articulates with the occipital condyles allowing you to look up and down. |
|
|
C2 (Axis). Articulates with C1 (Atlas) and allows you to turn your head left and right. Has a distinctive odontoid process (the part that sticks up) known as the dens |
|
|
Dens (Process of the C2 Vertebra that articulates with C1) |
|
|
Thoracic Spine. T1-12. These attach to ribs. The ribs are named first rib (attaches to T1), second rib (attaches to T2) and so on. The body is much larger than cervical vertebrae and unlike cervical, they do not have foramen in the transverse processes. Thoracic vertebrae all have articulation points for ribs (these are concave areas at the ends of the transverse processes) |
|
|
Lumbar Spine (L1-5). Much larger body that Thoracic vertebrae because they support more weight. |
|
|
Sacrum (5 fused vertebra that have passage for nerves) |
|
|
Coccyx (4 fused vertebra that the muscles of the pelvic floor attach to) |
|
|
Manubrium (top part of the three fused bones that make up the sternum) |
|
|
Body of the Sternum (central part of the fused bones that make up the sternum) |
|
|
Xiphoid Process (bottom part of the three bones that make up the sternum) |
|
|
Zygomatic Process of the Temporal Bone |
|
|
Cervical Spine (C1-7). These have the smallest vertebral bodies because they don't support as much weight. The transverse processes have holes in them called transverse foramen. C1 and C2 are specialized (Atlas and Axis) to allow you to look up, down, left, and right. |
|
|
Occipital Bone. Foramen Magnum and occipital condyles found here. |
|
|
Sphenoid Bone. Sella Turcica found here. This is the view of this bone from inside the skull, but it can be seen from the outside as well (it lies just behind the zygomatic arch on the left and right sides of the skull). |
|
|
Sphenoid Bone. This is the view of the bone from the outside, left side of the skull. The sella turcica is found here. |
|
|
Lacrimal Bone. Named for lacrimation (meaning secretion of tears), because the tear ducts (lacrimal ducts) are found here. The hole is called the nasolacrimal canal |
|
|
Mental Foramen (left). Transmits the terminal ends of the inferior alveolar nerve (cranial nerve 5) that supplies sensation to the teeth |
|
|
External Acoustic Meatus. Site of the ear canal. Found superior to the styloid process on the temporal bones |
|
Suture Line |
Squamosal Suture. |
|
Suture Line |
Occipital Suture. |
|
Suture Line |
Coronal Suture. |
|
|
Wormian Bone. Also called sutural bones or intra sutural bones. These are extra bone pieces that occur within a cranial suture. These are irregular bones that occur during ossification and though they are irregular, they are not rare. |
|
|
Infraorbital Foramen. Allows passage for the infraorbital artery, vein, and nerve which are branches of the maxillary branch (V2) of the trigeminal nerve (CN V), which is responsible for sensation in the face and motor functions such as biting and chewing. |
|
|
Vomer. This is a small, thin bone that separates the left and right nasal cavities |
|
|
Palatine Bones (Left and Right). Commonly called the hard palate (along with the maxilla) |
