Hair Follicle Receptors

terminationes nervorum folliculorum pili

Hair follicle receptors are nerve endings wrapped around and running along the roots of hair follicles in hairy skin. When a hair bends, the follicle moves and stimulates these endings. They include rapidly adapting lanceolate endings and circumferential endings, and are linked to Merkel cells near some follicles.

Anatomical Data

Structure & Supply

LocationAround hair follicles in hairy skin throughout the body
Parts
  • Longitudinal lanceolate endings
  • Circumferential endings
  • Associated Merkel cells
Nerve SupplyA-beta, A-delta and C-tactile sensory fibres of the regional cutaneous nerves
Blood SupplyPerifollicular capillary network
Biomechanics

Function & Actions

Detect bending of hairs and light movement across hairy skin.

Clinical Relevance

Clinical Notes

Hair follicle receptors explain why we feel even slight hair movement, such as an insect landing on the arm. In hairy skin, which lacks Meissner corpuscles, they are the main detectors of light moving touch. Slow C-tactile fibres around follicles respond to gentle stroking and are thought to support pleasant, social touch.

Allodynia

Pain from normally harmless touch, such as brushing hair or clothing, seen in neuropathic pain and conditions like shingles.
