Intervertebral joints The Vertebral Column Protects the Spinal
Intervertebral joints & The Vertebral Column - Protects the Spinal Cord - Supports the Head & Trunk It is formed of 26 peaces: • 24 Vertebrae • One Sacrum (5 fused vertebrae) • One Coccyx (3 - 4 partly fused Coccygeal vertebrae) 12/17/2021 1

Each Vertebra Has: 1. Body 2. Vertebral Arch 3. Vertebral Foramen Between the Arch the Body 12/17/2021 9
The Arch consists of: 1. A pedicle on Either Side 2. A lamina on Either Side 3. At the Junction of the Pedycles & Lam there are Three Processes 12/17/2021 10

At C 1, base of the nose and the hard palate. At C 2, the teeth of a closed mouth. At C 3, the mandible and hyoid bone. At C 4, the common carotid artery bifurcates. From C 4– 5, the thyroid cartilage From C 6– 7, the cricoids cartilage 12/17/2021 23
At C 6, the esophagus becomes continuous with the laryngopharynx and also where the larynx becomes continuous with the trachea. It is also the level where the carotid pulse can be palpated against the transverse process of the C 6 vertebrae. 12/17/2021 24
