axial skeleton consists of the bones of the head, neck and trunk
Appendicular skeleton includes the bones of the arms, legs and girdles
Long Bones A bone is considered a _________ bone if it is longer than it is wide and it has chubby ends. examples are finer bone, thigh bone, Tibia and Fibia
Short Bones not longer than they are wide. They are often cube shaped. Examples are wrist bones
Flat Bones They are just that - flat. They are like sheets of molded clay. Examples are sternum and cranial bones
irregular Bones Have processes, spines, and ridges that stick out and serve as attachments points for tendons and ligaments
Sesamoid Bones Look like sesame seeds . They grow on tendons where there is a lot of friction.
Foramina or foramen Holes or openings in the skull. They allow passage of blood vessels and nerves
Foramen Magnum The occipital bone contains a large opening called ________, which allows the spinal cord to exit the cranial cavity.
external occipital protuberance Located on the occipital bone's posterior surface. It is typically larger in males and is an attachment point for a tendon to connect muscle to the bone.
ethmoid and sphenoid irregular bones that make up the majority of the cranial cavity floor.
cribiform The ethmoid bone includes a structure called the ______ plate. This plate consists of two depressions in the cranial cavity's anterior floor. Has many wholes for nerve endings to pass through
Sella Turcica formed by the sphenoid bone , this bone houses the pituitary gland and is in a shape of a saddle.
conchae The ethmoid bone forms long bony ridges called _________. in the nasal cavity.
List the spinal column bones 7 cervical bones, 12 thoracic bones, 5 lumbar bones, 1 sacrum and 1 coccyx
List the facial bones nasal, lacrimal, zygomatic, inferior nasal concha, maxilla, palatine, mandible, vomer.
List the cranial Bones frontal, occipital, temporal,parietal, ethmoid and sphenoid
Sphenoid Bone Forms part of the cranial floor. Lateral posterior portion of eye orbits. Lateral portion of cranium anterior to temporal bones.
Ethmoid bone Anterior portion of the cranium, including medial surface of the eye orbit and roof of nasal cavity.
Temporomandibular Joint Where the mandible and temporal bone are joined.
Maxillae Form upper jaw, anterior portion of hard palate, part of lateral walls of nasal cavity and floors the eye orbits.
saccrum There is only one. Attached at the end of the lumbar vertabras. Five fused sacral bones. Forms posterior wall of pelvic girdle
Coccyx tail bone. Three to five fused rudimentary vertebrae
Palatine bones Form posterior portions of hard palate, lateral wall of nasal cavity
zygomatic bones cheek bones. Also form floor and lateral wall of each eye orbit
lacrimal bones medial surfaces of eye orbits
Nasal bones Form bridge of the nose
vomer In midline of nasal cavity. Forms nasal septum with the ethmoid bone
Inferior nasal conchae attached to lateral walls of nasal cavity
mandible lower jawbone. Only movable skull bone.
Intervertebral Disks shock absorbers
Four Curvatures Cervical Curvature, Thoracic Curvature, Lumbar Curvature and Sacral Curvature
Scoliosis abnormal spinal curvature with a lateral curve
Kyphosis abnormal spinal curvature: hunchback
Lordosis abnormal spinal curvature: Swayback
Herniated Disk Herniation with soft matrix oozing out. Places pressure on the spinal cord or spinal nerves. Can cause severe pain
Cervical Vertebrae Support neck
Atlas: Cervical Vertebra 1 Articulates occipital condyles of occipital bone. Supports head
Axis: Cervical Vertebra 2 possesses the odontoid process (Dens) . Serves as a pivot point for atlas
Thoracic Vertebrae Larger vertebra with longer spinous process then cervical vertebrae
Ribs Articulate on the facets of the transverse processes and bodies
Lumbar Vertebrae Heavy, thick bodies to support greater stress and weight. Larger processes for attachment of back muscles
