Axial Skeleton Vertebral Columm

• disc-shaped, weight-bearing region

  .

  A) Body

  
• Spinous processes project posteriorly, and transverse processes project laterally

  .

  A) Transverse Process

  B) Spinous Process - Spine of Vertebra

  
• Lable the fallowing items marked in tape

  .

  A) Body

  B) Transverse Process

  C) Spinous Process - Spine of Vertebra

  
• The atlas has no body and no spinous process. The superior surfaces of lateral masses articulate with the occipital condyles

  .

  A) Cervical Vertebra - Atlas (C-1)

  
• The axis has a body, spine, and arches as do other cervical vertebrae. The dens is a pivot for the rotation of the atlas


  .

  A) Axis ( C-2)

  
• The five lumbar vertebrae (L1-L5) are located in the small of the back and have an

  enhanced weight-bearing function. They have large, kidney-shaped bodies and flat hatchet-shaped spinous processes - ( Distinguished by Spine going straight back )

  .

  A) Lumbar Vertebra

  
• There are twelve vertebrae (T1-T12) all of which articulate with ribs. Major markings include two facets on the heart-shaped body for articulation of ribs, and a long spinous process -(Distinguished by downward angle)

  .

  A) Thoracic Vertebra

  
• Seven vertebrae (C1-C7) are the smallest, lightest vertebrae. C3-C7 are distinguished with an oval body, short spinous processes, and large, triangular vertebral foramin - ( Distinguished by holes )

  .

  A) Cervical Vertebra

  
• along with body enclose the vertebral foramen

  .

  A) Vertebral Arch

  
• make up the vertebral canal through which the spinal cord passes

  .

  A) Vertebral Foramen

  
• Lable the fallowing Items in tape

  .

  A) Vertebral Foramen

  B) Vertebral Arch

  
• Consists of five fused vertebrae (S1-S5), which shape the posterior wall of the pelvis. The L5-S1 intersection is the sight of most low-back pain

  .

  A) Sacral Vertebra - Sacrum

  
• What is a major markings of the sacral vertebrae (sacrum)

  sacral canal, sacral hiatus,

  A) Sacral Foramina

  
• The coccyx is made up of four (in some cases three to five) fused vertebrae that articulate superiorly with the sacrum

  .

  A) Coccygeal Vertebrae (Coccyx)

  
• Lable the following items in tape

  .

  A) Sacral Vertebra - Sacrum

  B) Sacral Foramina

  C) Coccygeal Vertebrae (Coccyx)

  
• A dagger-shaped, flat bone that lies in the anterior midline of the thorax. Results from the fusion of three bones – the superior manubrium, the body, and the

  inferior xiphoid process

  .

  A) Sternum ( Body of Strenum)

  
• Results from the fusion of three bones – the superior manubrium,


  .

  A) Manubrium

  
•  Results from the fusion of three bones-inferior xiphoid process 


  .

  A) Xiphoid Process

  
• How many true ribs ?

  7
• How many floating ribs

  2
• How many false ribs ?

  3
• Lable the fallowing items in tape

  .

  A) Sternum ( Body of Strenum)

  B) Manubrium

  C) Xiphoid Process

  D) 3 false ribs

  E) 7 true ribs
