CH. 16 Pain, Temperature Regulation, Sleep, and Sensory Function

Set of flashcards based on notes from Chapter 16 covering key concepts in pain, temperature regulation, sleep, and sensory functions.

Pain

An unpleasant sensory and emotional experience associated with actual or potential tissue damage.

Nociception

The processing of pain, involving transduction, transmission, perception, and modulation.

Transduction

The phase where tissue damage by noxious stimuli is converted to electrophysiologic activity.

Pain threshold

The lowest intensity of pain that a person can recognize.

Pain tolerance

The greatest intensity of pain that an individual can endure.

Thermoregulation

The process of balancing heat production, conservation, and loss.

Hypothalamus

The part of the brain that controls temperature regulation.

Fever

A temporary resetting of the hypothalamic thermostat due to pyrogens.

REM sleep

Rapid Eye Movement sleep, characterized by vivid dreaming and is 20%−25% of sleep time.

NREM sleep

Non-Rapid Eye Movement sleep, known for restorative processes and includes N1, N2, and N3 stages.

Olfactory Dysfunction

Impairments in the sense of smell, which can include hyposmia, anosmia, and olfactory hallucinations.

Hyposmia

Impaired sense of smell.

Presbycusis

Age-related hearing loss, especially in high-frequency sounds.

Proprioception

Awareness of the position and location of body parts, important for balance and coordination.

A-beta fibers

Large myelinated fibers that transmit touch and vibration sensations.

Segmental inhibition

A pain modulation process where A-beta fibers inhibit pain transmission.
