Physiology and Psychology of Pain Quiz

The _____________ is a quick and easy way to assess pain where the patient marks an X on a line 10 cm in length.

Visual Analogue Scale

Fastest conduction velocity; found in muscles and tendons and provide proprioceptive information.

A-Alpha

Slowest conduction velocity; found in the skin and provide pain, touch, pressure, and temperature information

C

Slow conduction velocity; slightly myelinated, found and the skin and provide touch, pressure, temperature and pain information

A-Delta

Fast conduction velocity; found in the skin and provide touch and vibration information

A-Beta

First order neurons transmit impulses from the sensory receptors to the dorsal horn of the spinal cord.

True

____________ are mechanoreceptors located in the dermis, are responsible for detecting vibrating or moving stimuli on the skin, and adapt to stimuli rapidly

Meissner's Corpuscles

During the withdrawal reflex, the sensory signal is sent to the spinal cord, crosses through the _____________ of the spinal cord, and exits the spinal cord with a motor signal that leads to a response

Interneuron

________________ are activated by severe chemicals released when tissue is damaged and generates a pain sensation that is slow in onset, duller in intensity and diffusely localized.

C nociceptors

___________ are located in the epidermis of the skin and are responsible for detecting very light touch to the skin

Merkel's Disks

Pain tolerance is the level of noxious stimulus required to alert the individual to a potential threat to tissue

False

_____________ is described as chronic pain that is a result of an underlying disease such as arthritis or a tumor

Nociceptive Chronic Pain
