All sensations excluding vision, hearing, taste, smell, and balance.

Includes touch, temperature, proprioception, and nociception.

Receptors signaling potential pain, but pain perception varies.

First-order neurons transmitting signals from skin to spinal cord.

Third-order neurons relaying sensory info from thalamus to cortex.

The point where sensory pathways cross in the nervous system.

Sensory structures that encode environmental energy into signals.

Specialized nerve endings like Golgi tendon organs and Pacinian corpuscles.

To determine presence and severity of sensory impairment and its location.

An assessment that includes sensory exams alongside history and physical evaluation.

The process of distinguishing between different conditions based on symptoms.

Includes screening and comprehensive testing to assess sensation types.

Sensations like nociception, temperature, light touch, and pressure tested on skin.

Conveys sensations of proprioception, vibration, and discriminatory touch.

Transmits sensations of pain and temperature to the brain.

Procedures to ensure accurate and reliable sensory testing results.

Recording modalities tested, grading, and patient impact during evaluation.

Assessing awareness of body position and movement through joint position tests.

Pain is always an output of the brain, regardless of tissue damage.

Pain does not equal the amount of tissue damage.

Pain is influenced by thoughts, activity, sleep, mood, and stress.

Acute pain serves a useful protective function to warn of danger or injury.

Chronic pain results from a hypersensitive nervous system; it often doesn't warn of damage.

Many treatments can help reduce a hypersensitive nervous system and improve quality of life.

Nociceptors signal injury, but their activity alone isn't sufficient to cause pain.

Fast nociception is well-localized, sharp, and short-lasting.

Slow nociception is dull, aching, poorly localized, and longer-lasting.

A theory stating mechanical stimulation can decrease pain perception by 'closing the gate' on pain messages.

A neuropeptide that plays a role in maintaining nociceptive signals, elevated in chronic pain.

Pain perceived in a different area from the source, commonly happening between viscera and skin.

Sensory change without stimuli, such as tingling or prickling sensations.

Unpleasant abnormal sensations; includes allodynia and hyperalgesia.

The most reliable pain indicator is the patient’s self-report; pain is subjective.

Pathways that transmit sensory information from the body to the brain, including spinal nerves and ascending tracts.

Part of the anterolateral system that transmits fast nociception and temperature sensations.

A sensory region of skin corresponding to a specific spinal nerve root.

Compares intended movements to actual movements and adjusts them for coordination.

Pain that comes on suddenly due to a specific injury or tissue damage.

Pain that lasts longer than expected for tissue healing, sometimes without clear cause.

Pain resulting from damaged nerves in the absence of peripheral receptor activation.

A condition caused by pressure on a nerve, leading to sensory deficits.

Dysfunction or pathology in a peripheral nerve affecting sensation and motor control.

Loss of all sensation and motor function below the level of the injury.

Hemisection of the spinal cord leading to ipsilateral loss of proprioception and contralateral loss of pain/temperature.

Acts as a relay station, processing sensory and motor signals between different brain areas.

Mediated by C fibers, this system handles poorly localized pain and emotional responses.

Receptors that respond to external stimuli, located on the skin.

Receptors that respond to internal stimuli, found in organs like the heart and digestive tract.

Receptors that provide an internal sense of body position and movement, found in joints and muscles.

Also known as tonic receptors; they continue to fire as long as there is a stimulus.

Also known as phasic receptors; they stop firing soon after the stimulus is applied.

Receptors that respond to mechanical deformation like touch and vibration.

Receptors that respond to potential tissue-damaging stimuli, interpreted as pain.

Pathway for discriminative sensations like touch and proprioception; heavily myelinated.

First order fibers that carry sensory information from receptors to the CNS.
