What does funiculus mean?
"Funiculus" is the Latin-derived term for a slender, cordlike structure composed of bundled fibres. In human and veterinary anatomy it most often denotes one of the columns into which the white matter of the spinal cord is divided — the anterior, posterior, and lateral funiculi — each carrying distinct tracts of sensory and motor nerve fibres. Botanists use the same word for the small stalk that anchors an ovule to the placenta within a flower's ovary, through which nutrients pass to the developing seed; the scar left when the seed detaches is called the hilum. The word comes from Latin funiculus, a diminutive of funis, meaning rope or cord, which also gave us the funicular railways that haul passengers up steep slopes on cables. Because it describes such specific structures, funiculus belongs firmly to specialist vocabulary in medicine and plant science rather than everyday language, but it remains a precise and widely used term in both fields.
nounA slender cordlike structure or bundle of fibres, especially in anatomy and botany; in botany specifically the stalk attaching an ovule to the placenta, and in neuroanatomy one of the longitudinal divisions of white matter in the spinal cord.
- In anatomy/neuroanatomy: any of the cordlike bundles of nerve fibres forming divisions of the spinal cord's white matter.
- In botany: the stalk by which an ovule (and later the seed) is attached to the placenta of the ovary.
"The surgeon traced the funiculus carefully to avoid severing the nerve pathway."
"The lateral funiculus of the spinal cord contains ascending sensory pathways."
"Under the microscope, each seed remained joined to the ovary wall by its delicate funiculus."
The plural follows Latin convention; "funiculi" is standard in anatomical and botanical literature, though anglicized forms are occasionally seen.
"Both anterior funiculi of the spinal cord carry descending motor tracts."
Every time you ride a funicular railway up a mountainside, you're riding the same Latin word doctors use for the nerve tracts running down your spinal cord.

Etymology of funiculus
"Funiculus" comes directly from Latin, where it was a diminutive of funis, "rope" or "cord," literally meaning "little rope." The same root produced the adjective funicular and underlies the noun funicular railway, named for its cable, as well as funambulist, referring to a tightrope walker. The term was adopted into anatomical and botanical nomenclature in early modern scientific Latin to describe cordlike biological structures.

How funiculus is actually used
"Funiculus" is a technical term confined almost entirely to medical, neurological, and botanical writing; it rarely appears in general prose. Its plural "funiculi" is standard in scientific literature.
Easily confused with funiculus
"Funicular" is an adjective (or a noun for a cable-hauled railway) derived from the same Latin root, whereas "funiculus" is the anatomical or botanical cord itself.
