  • Title: [The formation of the segmental projections of the primary afferents of the wing and leg in the chick embryo spinal cord].
    Author: Poliakova LA, Velumian AA.
    Journal: Zh Evol Biokhim Fiziol; 1991; 27(4):496-502. PubMed ID: 1799104.
    Abstract:
    A comparative HRP study of formation of connections between primary sensory nerve fibers and motoneurones in brachial and lumbosacral cord segments has been made on chick embryos between the 6.5th and 10th days of incubation. HRP was applied to the cut ends of the appropriate nerves via suction pipettes on isolated superfused spinal cord preparation. The first contacts between primary sensory collaterals and motoneuronal dendrites were found to appear both in lumbosacral and branchial cord segments at the same stage, i.e. at the 7.5-8th days of development. This observation does not confirm the widely accepted belief on rostrocaudal sequence of development of the spinal cord, indicating that exceptions from this developmental gradient are quite possible.
