CLT Anatomy & Physiology for Laser Therapy 2

Question 1

Which layer of the skin contains the fibroblasts primarily responsible for collagen synthesis targeted in laser therapy?

Accepted Answer

Dermis

Answer

The dermis contains fibroblasts that produce collagen and elastin, making it the primary target for laser-stimulated tissue remodeling.

Question 2

What is the primary chromophore in melanin-targeting laser treatments?

Accepted Answer

Eumelanin

Answer

Eumelanin is the dominant brown-black pigment that selectively absorbs laser energy in pigment-targeting treatments.

Question 3

Which nerve fiber type is most involved in transmitting the pain signals that low-level laser therapy aims to modulate?

Accepted Answer

C fibers

Answer

C fibers are unmyelinated slow-conducting fibers that transmit chronic pain and are a key target for photobiomodulation analgesic effects.

Question 4

The Langerhans cells found in the epidermis primarily serve what function relevant to laser treatments?

Accepted Answer

Immune surveillance and antigen presentation

Answer

Langerhans cells are dendritic immune cells in the epidermis that help modulate the inflammatory response triggered by laser energy.

Question 5

Which anatomical structure in a hair follicle is responsible for hair regeneration and is a consideration in laser hair removal?

Accepted Answer

Bulge region

Answer

The bulge region contains hair follicle stem cells responsible for regeneration, and effective laser hair removal must damage this area to prevent regrowth.
