Articulations The four major bones of the neurocranium: • Occipital • Parietal • Temporal • Frontal These bones join at sutures, which are bound together by fibrous connective tissue
Articulations • The base of the skull articulates with the atlas (C1), the first cervical vertebra of the vertebral column • The mandible articulates with the two temporal bones on each side at the temporomandibular joint
Individual Vertebrae • The following views are vertebrae from the human spinal column • Some are neck vertebrae and others are mid- and lower-back vertebrae • Most vertebrae consist (are made up of) the same parts
Cervical Vertebrae – C1 and C2 Superior View What are the names for C1 and C2? Answer: C1=Atlas and C2=Axis What is unique about these two vertebrae? Answer: They articulate for head nod and pivot What is the difference between C1 and all other vertebrae? Answer: C1 has no body or spinous process – it is basically a “ring”
C1 and C2 Let’s see, we said that C 1 was called what? Hint: Maps of the world are also known as this Answer: Atlas And the name for C2? Hint: The earth spins on this Answer: Axis C1 is shaped like this piece of jewelry. Answer: a ring
Cervical Vertebrae – C1 and C2 Superior View continued… Do you recognize view #1? Answer: C1-7 Cervical Vertebrae Do you recognize view #6? Answer: Spinous process of Axis Do you recognize view #7? Answer: Transverse process of Axis Do you recognize view #9? Answer: Body of Axis
Name views 1, 6, 7, and 9 Cervical vertebrae 1-7 Spinous process of axis Transverse process of axis Body of axis Axis is your 2nd neck vertebrae
Cervical Vertebrae C3-7, Superior View Do you recognize view #1? Answer: C1-7 Cervical Vertebrae Do you recognize view #2? Answer: Spinous process Do you recognize view #6? Answer: Transverse process Do you recognize view #7? Answer: Body Do you recognize view #9? Answer: Vertebral foramen
Thoracic Vertebra – Superior View How many thoracic vertebrae are in the human body? Answer: 12 (T1-12) T1-12 lie between the cervical and lumbar regions and attached to what bones? Answer: ribs The articular processes project up and down from the left and right sides of the vertebral arch and form joints. What are these joints called? Answer: Facet joints
Thoracic Vertebra – Superior View continued… Do you know view #4? Answer: Spinous process Do you know view #5? Answer: Vertebral body Do you know View #6? Answer; Vertebral foramen Numbers 3 and 7 are facet joints Did you notice that all vertebrae except C1 and 2 are practically the same?
Lumbar Vertebra – Superior View How many lumbar vertebrae are in the human body? Answer: five (L1-5) Do you know view #3? Answer: Spinous process Do you know view #7? Answer: Body Do you know view #8? Answer: Transverse process
Thoracic and Lumbar Vertebrae • Each thoracic vertebrae, like most all vertebrae, have similar structures: a body, vertebral arch, spinous process, pair of transverse processes and two pairs of articular processes • Lumbar vertebrae are the largest in the body. Their large size directly relates to weight-bearing responsibilities
The Spinal Column Can you name views #1-5? Answers: Cervical, Thoracic, Lumbar, Sacrum, Coccyx What directional view is this spine facing? Answer: posterior Can you name views #6-9? #6: Transverse process; #7: Spinous processes; #8: C2/Axis; #9: C1/Atlas
Spinal Column Articulations • The vertebral column is flexible due to its many articulations • Although acting as a single unit, it is really the sum of many small movements (at joints between the vertebrae) • Each vertebra forms three separate joints with the vertebra above or below it: with a pair of facet joints and a single anterior intervertebral joint • T1-10 articulate with rib pairs 1-10
Spinal Column continued… • Do you know the directional view we are looking at now? • Answer: lateral • Is this view a left or right view? • Answer: left • Again, can you name the five regions of the human spinal column? • Answer: • Cervical • Thoracic • Lumbar • Sacrum • Coccyx
Spinal Column continued… Do you know what view #1 represents? Answer: Intervertebral disks Do you know what #4 represents? Answer: Lumbar vertebrae Do you know what #2 and #3 represent? Answer: #2=sacrum and #3=coccyx

Talus Bone • Although considered a foot bone, the talus articulates with the tibia and fibula at the ankle joint • We will learn more about the feet and hands later in term 3

Answer: Anterior superior iliac spine Name view #6. Answer: Ischium Name view #10. Answer: Coccyx Name view #12. Answer: Sacrum Name view #14. Answer: Ilium
