Isotropic bands

Short description: Lighter bands of skeletal muscle cells

In physiology, isotropic bands (better known as I bands) are the lighter bands of skeletal muscle cells (a.k.a. muscle fibers). Isotropic bands contain only actin-containing thin filaments.^[1]

The darker bands are called anisotropic bands (A bands). Together the I-bands and A-bands contribute to the striated appearance of skeletal muscle.

Isotropic bands indicate the behavior of polarized light as it passes through I bands.^{[citation needed]}

Diagrams provide an indication of what I and A Bands look like, through a microscope.
