|
Paranasal Sinuses |
Hollow air filled spaces Lined w/nasal mucosa Help lighten skull weight Reduce bone mass Add resonance to voice |
|
|
Ethmoid Bone |
|
|
|
Adult vertebral column |
|
|
|
Vertebra |
|
|
|
Intervertebral Disc Padding for weight bearing. Can change shape. Allows for movement between vertebrae. Movement is small with 2 but increase as they all move. |
Fibrocarilaginous pad Thin in cervicle thicker in lumbar. |
|
|
Sacrum & Coccyx |
5 sacral vertebrae fused after 20 yr of age |
|
|
Thoracic Vertebrae |
Distinguised by spinous process. Long and projects downward. Has articulation sites (facets) on the body and a transverse process for rib attachment. |
|
|
Cervical Vertebrae |
C-1 Atlas doesn't have a body or spinous process
C-2 Upward projecting dens that articulates with the anterior arch of atlas. Others- small body, bifid spinous process, transverse process/foramen |
|
|
Rib Articulation in Thoracic Vertebrae |
Has superior/inferior articular facets on the body for articulation with the head of rib. Has a Transverse process facet for articulation with the rib tubercle. |
|
|
Lumbar Vertebrae Carry the most body weight. Largest and Thickest vertebrae |
Large thick body. Short rounded spinous process. |
|
|
Ligaments of Vertebral Column |
A.L.L.- runs down the front, uniting all. S.P.-connects the spinous processes of the thoracic/lumbar. |
|
|
Thoracic Cage Pg 293 |
12 ribs anchored posteriorly to the thoracic vertebrae. Sternum anchors anterior thoracic cage. |
|
|
Development of skull |
Bones not ossified. Separated by fontanelles filled with fibrous connective tissue. Disappear by 2 yrs. |
|
|
Development of Vertebral Column/Thoracic Cage |
Begins with mesenchyme cells. The differentiate into cartilage model then ossify into bone. |
|
|
Adult Bones |
206 |
|
|
Kid Bones |
Kids have a higher number of bone because they fuse together as they grow. |
|
|
Axial and Appendicular Skeleton |
Protects internal organs, provides support, and movement of body. Primary storage of minerals (ex.calcium and phosphate) Bone marrow stores fat and houses the blood cell producing tissue of the body. |
|
|
Axial Skeleton 80 bones (skull, vertebral column, thoracic cage) |
Forms the vertical central axis of the body. Includes head, neck, chest, & back. Protects brain, spinal cord, heart and lungs. Serves as attachment site for muscles that move the head, neck, back, hip joints, shoulders. |
|
|
Vertebral Column |
24 bones |
|
|
Thoracic Cage |
Includes 12 pairs of ribs, sternum, and the flat bone of the anterior chest. |
|
|
Appendicular Skeleton 126 bones |
Upper/Lower Limbs including bones that attach each limb to the axial skeleton. |
|
|
Nasal Concha |
Surperior/Middle are ethmoid bone. Inferior are a independent bone of the skull. |
|
|
Hyoid Bone |
Independent bone that does not contact any other bone and is NOT part of the skull U shapped. Attached to the larynx below and the pharynx posteriorly. Held in place by muscles. |
