The nervous system is the primary messaging and master control/
regulatory system of the body
1. Receiving stimuli (sensory, afferent)
stimulus arrives at CNS brain and spinal cord
◦ Nerves: bundles of axons TEA
◦ Peripheral nervous system viiiis kfi.sn
inferential
◦ Afferent nerves - from environment to CNS
special senses: sensory pathways that require special sense organs to send
stimuli to the CNS
1. Eye - light energy
2. Nose - olfaction - chemical energy
3. Ear - auditory/equilibrium (balance) - mechanical energy
4. Tongue - gustation - chemical energy
general senses: sensory pathways that do not require a special sense organ. it
uses nerve endings in the skin (dendrites, receiving end)
1. Temperature - thermoreceptor
2. Touch/pressure - mechanoreceptors
3. Proprioception - body awareness
4. Pain - nociceptors
2. Integration: stimuli is interpreted by the brain to decide on an
