neural arch n.
See vertebral arch.
Lastly there are a pair of minute projections arising from the posterior end of the neural arch, below the postzygapophyses.
The base of the neural arch is also concave in this vertebra.
The prezygapophyses are situated at the sides of the anterior end of the neural arch, and look directly outwards.
The middle part of this articular joint is made by the body of the vertebra; its outer parts are in the neural arch.
Between the base of the neural arch and its successor is a small foramen for the exit of the spinal nerve.
The jagged edge directly posterior to the area occupied by the neural arch in the type extends 0.5 mm.
The neural arch is low, and is drawn out into a slight blade-like neural spine.
The neural arch is slightly depressed; its width is somewhat less than the width of the cotyle.
The exoccipitals also bear a pair of surfaces for articulation with corresponding ones on the neural arch of the first vertebra.
neural arch and spine a little less in height than length of centrum.
