funiculus

 [fu-nik´u-lus] (pl. funic´uli) (L.)
cord: anatomical nomenclature for a cordlike structure or part, especially one of the large bundle of nerve tracts that make up the white matter of the spinal cord. adj. adj funic´ular.
anterior funiculus ventral funiculus.
dorsal funiculus the white substance of the spinal cord lying on either side between the posterior median sulcus and the dorsal root.
lateral funiculus (funiculus latera´lis) the lateral mass of fibers on either side of the spinal cord, between the anterolateral and posterolateral sulci.
posterior funiculus dorsal funiculus.
funiculus sperma´ticus the spermatic cord.
ventral funiculus the white substance of the spinal cord lying on either side between the ventral median fissure and the ventral roots of the spinal nerves.

cord

The whole cross- section (section), grey matter (GM), dorsal horn (DH), ventral horn (VH), white matter (WM), dorsolateral funiculus (DLF), and ventrolateral funiculus (VLF) were analyzed for sparing (b).
For the stab injury to the dorsal funiculus, the trace of the needle tract and accompanying damage to the dorsal column were revealed by the eriochrome cyanine R staining (Figure 3(d)).
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.
The majority of this assimilate enters the seed coat through the funiculus and then moves symplastically to either the ovule or the fiber (Ryser, 1992).
Stim: stimulation; Rt: right; cut: left C5 segmental hemisection of cervical cord; short broken line: dorsal corticospinal tract (posterior funiculus); long broken line: ventral corticospinal tract; arrow: sprouting; gray line: activation of the ventral corticospinal tract; arrow head: contralateral additional C2 hemisection.
These pores are plugged with cell complexes that aid in the transport of material through the cells of the funiculus (Bobin, 1977; Mukai et al., 1997).
funiculus: Stalklike structure connecting an ovule to its placental surface within an ovary.
The number and type of sensilla found on the funiculus and potential sexual dimorphism in these structures have not been determined.
In the literature, mainly concerning ovine species, descriptions about the vascular arrangement of the spermatic funiculus have been observed (NOORDHUIZEN-STASSEN et al., 1985; CARVALHAL et al., 2000) and little attention has been given to caprine species (SOUZA et al., 1992; OLIVEIRA et al., 2002).
Green fluorescent protein (GFP)-OECs, or OECs prepared from GFP transgenic rats, were transplanted into a chemically induced demyelinating lesion in the rat dorsal funiculus (Figure 2).
In the transverse sections, the only gross lesion observed was a thin, white discolored area in the left dorsal funiculus in the cranial cervical spinal cord segments.
