چکیده

Unit electrical activity was recorded from single neurons in the isolated lumbo-sacral spinal cord of 14- to 19-day chick embryos, in situ. Spinal cord transection was combined with transection of all lumbo-sacral dorsal roots. The spontaneous discharge of cells is confined, for the most part, to the lower two thirds of the cord. A quasilinear reduction in the number of spontaneously active units was found during the developmental period studied. Comparable results were obtained in decentralized cord with sensory inputs blocked by xylocaine.

Histomorphometric study of the spinal cord segments in the chick and adult male ostrich (Struthio camelus)

In this study, the vertical, transverse and oblique diameters of the spinal cord segments (C1, C6, C12, C18, T1, T4, L1, L4, L6 and L8) and the ratio of gray matter to white matter in chick (l month) and adult (18 months) male ostriches, each group consisted of 3 animals, were measured with standard micrometric method using 6 μm thick sections by light microscope. With advancement of age, the r...

Compound Action Potential of Isolated Spinal Cord: A Biophysical Analysis to Address Activity of Individual Fibers Following Contusion Injury

Compound action potential (CAP) of spinal cord represents valuable properties of neural fibers including excitability, rate of myelination and membrane integrity. These properties are measured using amplitude, latency and area under curve of CAPs recorded from spinal cord. Here, the isolated spinal cord was set in a double sucrose gap (DSG) chamber and its response to intracellular stimulation ...

Regulation of acetylcholinesterase in cultured chick embryo spinal cord neurons.

Primary nerve cell cultures contain acetylcholinesterase (AChE: EC 3 .l .1.7) and other special macromolecules associated with cholinergic transmission [l--4 J . Cultured chick nerve cells, like cultured muscle, have been shown to release AChE into their medium [ 5 $1. The experiments presented here examined the levels of activity and release of AChE in nerve cell cultures after treatment with ...

Segmental lineage restrictions in the chick embryo spinal cord depend on the adjacent somites.

We have investigated whether the developing spinal cord is intrinsically segmented in its rostrocaudal (anteroposterior) axis by mapping the spread of clones derived from single labelled cells within the neural tube of the chick embryo. A single cell in the ventrolateral neural tube of the trunk was marked in situ with the fluorescent tracer lysinated rhodamine dextran (LRD) and its descendants...

A Chick Embryo in-Vitro Model of Knee Morphogenesis

   Background: In this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. Methods: The developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of ...
