Fig. 3. (A-D) Light micrographs of consecutive sections through a segmental artery
(sg.a.) taken 8 µm apart, showing the connection between interarterial
anastomoses (iaas) and secondary vessels (SV). The vessel path from
the coiled region of iaas (arrowheads in D) is denoted by stippled
arrows in A. Note the numerous nerve bundles (Ne) in association with
secondary vessels. Scale bar, 100 µm. Lissamine Fast Red, 2 µm
section.
