QuestionChoice
Aα fibre is a large diameter, myelinated afferent nerve fibre that carries information about proprioception from muscles. It is not involved in the pain gate theory.

Aα fibres
QuestionChoice
Aβ is a large diameter, myelinated afferent nerve fibre that carries information about heavy pressure, light touch, deep touch and vibration. Rubbing the knee causes signals to travel down the Aβ fibres blocking pain signals traveling in the C-fibres. In the pain gate theory, this action closes the pain gate.

QuestionChoice
Aγ fibre is a small-diameter, myelinated nerve fibre that innervates muscle spindles and is involved in regulating muscle spindle sensitivity and muscle tone. It is not involved in the pain gate theory.

QuestionChoice
C fibre is a small-diameter, unmyelinated nerve fibre that carries information about pain and temperature. The action of rubbing causes signals to travel down the Aβ fibres blocking pain signals traveling in the C-fibres. In the pain gate theory, this action closes the pain gate.

A 5-year-old boy tripped and hurt his knee. His mother started rubbing his knee to help ease the pain.

Which nerve fibre is being recruited to block the pain signals?
