Pathologies of the nervous system that may be recognized include deformities, atrophy, tumours, granulomas, haemorrhage, congestion, oedema and other anomalies recognised histologically as necrosis, encephalitis or meningitis. In vertebrates it consists of two main parts, called the central nervous system (CNS) and the peripheral nervous system (PNS). Chapter 10 Assessment. The SNS is the mobilization system often referred to as the fight-or-flight response. The primary role of the PNS is to connect the CNS to the organs, limbs, and skin.

However, it is only when disease or injury impair its function that we fully appreciate the relevance of our sensory modalities. Briefly stated, the nervous system coordinates controls and enables the vast majority of bodily function, including movement, thinking, autonomic, or automatic, things like pupil reflexes and sensory perception. The Nervous System is what helps all parts of the body to communicate with each other. Sensory receptors are dendrites of sensory neurons specialized for receiving specific kinds of stimuli. Sensory receptors are classified by three methods: 1,2 However, this tripartite classification of sensory neurons fails to convey the complexity of the neurons that encode stimuli as diverse as the temperature of the environment, texture of a surface, the direction of a .
