CT fibers, what do the circular fibers do? Where are they Circle the tooth
Transeptal Fibers Tooth to tooth, cementum from one to the other
What cell is responsible for collagen production? Fibroblasts
What is the connective tissue primarily composed of? Collagen fibers and fibroblasts
What are the ends of the periodontal fibers called that are embedded into the cementum and bone? Sharpey’s Fibers
Propriocepters, what are these? Transmit the perception of pressure to the brain, found in the PDL

Most common type of junction between the enamel and cementum is the most common? Cementum over Enamel
What is the main component of periodontal fibers? Collagen
If there is bleeding noted with a pt. what changes might you see in the gingiva due to this? Color, position of the gingiva caused by the swelling, and consistency, etc.
What is the bone between the roots between two adjacent teeth called? Interdental septum
