Clinical Cuts: Anatomy and physiology of the nervous system

Today's #ClinicalCuts is about everything... because the nervous system is involved in nearly everything we do, from how we see, to how we walk and talk!

The nervous system is divided into the central nervous system, the brain and the spinal cord, and the peripheral nervous system, which is further divided into the somatic and the autonomic nervous systems.

Broadly speaking, the nervous system can be split into an afferent and an efferent division.

The afferent division brings sensory information from the outside into the central nervous system, and includes visual receptors, auditory receptors, chemoreceptors, and somatosensory or touch receptors.

On the other hand, the efferent division brings motor information from the central nervous system to the periphery, ultimately resulting in contraction of skeletal muscles to trigger movement through the somatic nervous system, as well as contraction of the smooth muscles to trigger activity of the internal organs through the autonomic nervous system.
