Structure of the CNS  The CNS is a highly complex tissue that controls all of the body activities and serves as a processing center that links the body to the outside world.  It is an assembly of interrelated “parts”and “systems”that regulate their own and each other’s activity.  1-Brain                                   2-Spinal …

Water: comprises 60 - 90% of most living organisms (and cells) important because it serves as an excellent solvent & enters into many metabolic reactions Intracellular (inside cells) = ~ 34 liters Interstitial (outside cells) = ~ 13 liters Blood plasma = ~3 liters 40% of blood is red blood cells (RBCs) plasma is similar to interstitial fluid, but contains plasma proteins serum = plasma with clotting proteins removed intracellular fluid is…

TYPES OF TEETH The human permanent dentition is divided into four classes of teeth based on appearance and function or position. Incisors, Canines, Premolars & Molars…

INNERVATION OF THE DENTIN-PULP COMPLEX Dentine Pulp Dentin Nerve Fibre Bundle Nerve fibres The nerve bundles entering the tooth pulp consist principally of sensory afferent fibers from the trigeminal nerve and sympathetic branches from the superior cervical ganglion. There are non-myelinated (C fibers) and myelinated (less than non, A-delta, A-beta) fibers. Some nerve endings terminate on or in association with the odontoblasts and others in the pre…
