marginal layer

mar·gi·nal lay·er

the outer, nonnuclear layer of the embryonic neural tube; into its fibrous network grow the longitudinal nerve fibers that eventually become the white matter of the spinal cord and brainstem.
Synonym(s): marginal zone (2)

The current study revealed that the marginal layer of the basal plates of metencephalon in camel embryo undergoes extensive growth ventrally forming a bridge of nerve fibers (pons) that contains the pontine nuclei (Fig.
Mesencephalon: The marginal layer of each basal plate of mesencephalon enlarges and thickened forming the cerebral crura or peduncles (crura cerebri) while the alar plates of the mesencephalon give rise to the anterior and posterior colliculus which appear as two longitudinal elevations separated by a shallow midline depression (corpora quadrigemina) (Fig.
Neuron formation and migration: The neurons are produced in the ventricular zone (VZ) and migrate radially from the VZ to the developing cortex which consisted at the early stage, 1.5 cm CVRL camel embryo, of development from the primitive layers; ventricular, intermediate zone (IZ), and marginal layer (ml) (Fig.
The medial prefrontal cortex of the control group at x400 magnification showed the marginal layer with few scattered cells.

Close above the test specimen surface a thermal marginal layer is created where it is possible to investigate the interference fringes.
The balanced increase of the thermal marginal layer thickness is visible in the figures.
This topic also covers the visualization of temperature fields in a marginal layer on the interface wood--the surrounding environment.
The histological section of the cerebral cortex of the control group showed six cortical layers, from the superficial to deep; marginal layer, cortical plate, subcortical plate, intermediate plate, subventricular, and the ventricular zones.
There was less cellular population in the marginal layer, and a higher concentration of neurons in the cortical plate.
Photomicrograph of the section of the cerebral cortex of the control group showed six cortical layers; marginal layer (M), cortical plate (Cp), subcortical plate (Sp), intermediate plate (Ip), subventricular (SVz), and the ventricular zones (Vz).
