This document provides an extensive exploration of the senses and the somatic nervous system, detailing how the body perceives and processes various stimuli from the environment. It begins with an overview of sensory systems, focusing on how sensory information is received through afferent pathways and processed in the central nervous system (CNS). Key sensory modalities discussed include touch, proprioception, pain, temperature, and vision, with an in-depth look at the structure and function of...
