Variations in intrafusal fiber size within histochemically identified types of intrafusal fibers in the pigeon.
The myofibrillar adenosine triphosphatase reaction with acid preincubation allowed the identification of three types of intrafusal fibers in pigeon flexor carpi ulnaris muscle spindles. Measurements of cross-sectional areas at the polar region showed much overlap in fiber size among populations of each type.
