NEET PG DENTAL EXAM

Detailed explanation-1: -The brainstem reticular formation (RF) represents the archaic core of those pathways connecting the spinal cord and the encephalon. It subserves autonomic, motor, sensory, behavioral, cognitive, and mood-related functions.

Detailed explanation-2: -The reticular formation nuclei are found deep within the brainstem, along its length. It is easier to appreciate the approximate location of these nuclei if they are superimposed on a posterior view of the brainstem with the cerebellum removed.

Detailed explanation-3: -The reticular activating system (RAS) is composed of an ascending tract and a descending tract. The ascending RAS is responsible for human consciousness level and integrates the functions of the brain stem with cortical, cerebellar, thalamic, hypothalamic, and sensory receptor functions.
