Early studies have shown that more axons leave the dorsal funiculus in the upper cervical region of the spinal cord and that they innervate both sides of the grey matter.
It may be acting to (1) constrain the axons in the dorsal funiculus during decent, (2) regulate branching out of the dorsal funiculus, (3) restrict the axons to one side of the grey matter once they have entered the grey matter, (4) or be involved in fine-tuning the guidance as the axons find the interneurons or (5) involved in the topographic patterning of the CST--meaning that the axons behave differently depending on the relative concentration of EphA4 and ephrin ligand at different levels of the spinal cord.
The length of the antennae, and the length and width of the scape, pedicel and funiculus were measured with the Image Tool 3.
Testicular arteries showed a rectilinear itinerary in the ventrocaudal direction towards to the vaginal opening and together with veins and ductus deferens as part of the spermatic funiculus.
Identified olfactory ensheathing cells transplanted into the transected dorsal funiculus bridge the lesion and form myelin.
Wallerian degeneration occurred in the dorsal funiculus where the white discoloration was observed on gross examination.
After laying, the eggs attach to ovigerous hairs borne on the maternal ovigerous seta; the attachment is through a stalk called the funiculus (Herrick, 1895; Yonge, 1937, 1946, 1955; Cheung, 1966; Fisher and Clark, 1983; Goudeau and Lachaise, 1983).
The funiculus and investment coat, as well as the broken egg capsule, remain attached to the hairs after hatching (for further details, see Saigusa, 1994).
The orientation of the embryo within the EC remained the same, with the funiculus, or attachment stalk, at the distal edge of the presumptive cephalothorax.
The mechanism by which the fertilized egg is attached to the ovigerous hairs and the source of the material that makes up the funiculus and the egg capsule have been subjects of controversy for many years (e.
They are slightly ovate and attached by a funiculus, measuring around 1.
