Development of Descending Supraspinal Pathways in Birds,rvical cord, spinal motoneurons are first born at about 28 h of development comparable to Hamburger and Hamilton’s (HH) stage 8, those in the brachial cord around 52 h (stage HH15), and those in the lumbar cord around 56 h or stage HH17 (McConnell and Sechrist 1980).

Summary,an tetrapods and mammals is the apparent absence of somatomotor cortical areas giving rise to long descending projections to the spinal cord. The phylogenetic constancy of descending supraspinal pathways, at least of those arising in the brain stem, probably implies a comparable pattern of developmePastry 发表于 2025-3-25 02:18:42
