Schmidt-Lan·ter·man in·ci·sures

(shmit lahn'tĕr-mahn),
funnel-shaped interruptions of the major dense lines in the regular structure of the myelin sheath of nerve fibers, formerly interpreted as actual breaks in the sheath but shown by electron microscopy to correspond each to a strand of cytoplasm locally separating the two cytoplasmic aspects of the otherwise fused oligodendroglial (or, in peripheral nerves, Schwann cell) membranes composing the myelin sheath.

The anatomy of the medullary segments has been studied and described in humans (WILLIAMS et al., 1995), felines, monkeys (CARVALHO-BARROS et al., 2003), sheep (RAO, 1990), coatis (GREGORES et al., 2010), freshwater dolphins (MACHADO et al., 2003) and sea lions (FETTUCCIA; SIMOES-LOPES, 2004) , but the pattern of the medullary topography of M.
The medullary segments evaluated were the cervical (CS), thoracic (TS), lumbar (LS), and sacrocaudal (SCS) segments and the medullary cone (CM).

In the relationship between the medullary segments and the length of the vertebral column, the indices of the cervical, thoracic, lumbar and sacrocaudal segments are, respectively, 18.47, 35.26, 34.17 and 12.02% in Oryctolagus cuniculus (SANTOS et al., 1999), 22.40, 49.32; 24.07 and 3.68% in Felis concolor, 21.97, 50.83, 11.20 and 15.97% in Tamandua tetradactyla, and 28.02, 35.34, 19.68 and 6.93% in M.
