Pain & the Peripheral Nervous System

Parts of the peripheral nervous system responsible for carrying signals from the CNS to the body:

• autonomic division

• motor division

• sympathetic division

• parasympathetic division

Parts of the peripheral nervous system responsible for carrying signals from the body to the CNS:

• sensory division

• motor division

• sympathetic division

• parasympathetic division

Any structure int he body that receives and reacts to a motor neuron's signal, like muscles and glands:

• effector

• ganglia

• receptor

• neuron

The class of receptors in the PNS that send signals of pain:

• chemoreceptors

• nociceptors

• photoreceptors

• mechanoreceptors

How the brain receives, processes, interprets, and consciously experiences information sent to by the PNS:

• temperature

• perception

• stimulus

• time

General term for the internal or external event that is sensed by the PNS

• temperature

• stimulus

• pain

• time

General term for the detection of an internal or external stimulus by the nervous system:

• sensation

• stimulus

• perception

• pain

Part of the body that carries signals between the brain and spinal cord and the rest of the body:

• visceral nervous system

• autonomic nervous system

• peripheral nervous system

• central nervous system

Part of the brain that acts as a switchboard, first receiving sensory signals and sending them out to the appropriate regions of the cerebrum:

• cerebellum

• thalamus

• limbic system

• hypothalamus

Immediate reactions that don't need conscious processing from the brain, these involve sensation, transmission to the CNS, integration, transmission to an effector, and response

• reflexes

• affectors

• stimuli

• effectors
