| Culver's root | <botany> Dried rhizome and roots of Veronicastrum virginicum (family Serophulariaceae). Indigenous to North America. Formerly used as a cathartic. Synonym: black root, Culver's root. (05 Mar 2000) |

| cuticle of root sheath | cuticula vaginae folliculi pili |
| hair root | The part of a hair that is embedded in the hair follicle, its lower succulent extremity capping the dermal papilla pili in the deep bulbous portion of the follicle. Synonym: radix pili. (05 Mar 2000) |
| hairy root culture | A relatively new type of plant culture, which consists of highly branched roots of a plant, covered with a mass of tiny root hairs. These cultures do not require hormones or vitamins to grow, so they can grow on simple media of salts and sugars. Just as importantly, they produce secondary metabolites at levels similar to those made in the original plant, so they can be used as replacement plants for making such compounds as food flavours and fragrances.

| sensory root of ciliary ganglion | Sensory fibres passing from the eyeball through the ciliary ganglion to their cell bodies in the trigeminal ganglion via the nasociliary nerve. Synonym: radix sensoria ganglii ciliaris, ramus communicans nervi nasociliaris cum ganglio ciliari, radix nasociliaris, long root of ciliary ganglion, nasociliary root, radix longa ganglii ciliaris. (05 Mar 2000) |
| sensory root of pterygopalatine ganglion | <anatomy, nerve> The ganglionic branches, two short sensory branches of the maxillary nerve in the pterygopalatine fossa, the fibres of which pass through the pterygopalatine ganglion without synapse. Synonym: radix sensoria ganglii pterygopalatini, rami ganglionici nervi maxillaris, rami ganglionares, nervi pterygopalatini, nervi sphenopalatini, pterygopalatine nerves, sensory root of pterygopalatine ganglion. (05 Mar 2000) |
| sensory root of trigeminal nerve | <anatomy, nerve> The large sensory root of the trigeminal (or fifth cranial) nerve, extending from the semilunar ganglion into the pons through the middle cerebellar peduncle or brachium pontis, immediately lateral to the small motor root. Synonym: radix sensoria nervi trigemini, portio major nervi trigemini. (05 Mar 2000) |
| short root of ciliary ganglion | A branch of the oculomotor nerve supplying parasympathetic preganglionic nerve fibres to the ciliary ganglion. Synonym: radix parasympathica ganglii ciliaris, radix oculomotoria ganglii ciliaris, motor root of ciliary ganglion, oculomotor root of ciliary ganglion, radix brevis ganglii ciliaris, short root of ciliary ganglion. (05 Mar 2000) |
| spinal root of accessory nerve | <anatomy, nerve> Originates from the upper five or six cervical spinal segments, emerges from the lateral surface of the spinal cord and ascends through the foramen magnum to join the cranial root. Synonym: radices spinales nervi accessorii, ramus externus nervi accessorii, pars spinalis nervi accessorii, spinal part of accessory nerve. (05 Mar 2000) |
| nasociliary root | Sensory fibres passing from the eyeball through the ciliary ganglion to their cell bodies in the trigeminal ganglion via the nasociliary nerve. Synonym: radix sensoria ganglii ciliaris, ramus communicans nervi nasociliaris cum ganglio ciliari, radix nasociliaris, long root of ciliary ganglion, nasociliary root, radix longa ganglii ciliaris. (05 Mar 2000) |
| nerve root | One of the two bundles of nerve fibres (dorsal and ventral roots) emerging from the spinal cord that join to form a single segmental (mixed) spinal nerve; some of the cranial nerves are similarly formed by the union of two roots, in particular the fifth or trigeminal nerve; in the case of the eighth cranial (vestibulocochlear) nerve, each of its two components (vestibular root and cochlear root) is referred to as a root even though they do not join each other and their central connections are distinctive, conjoined nerve root, two adjacent nerve root's with the same common origin from the dura mater. (05 Mar 2000) |
| nerve root sleeve | In myelography, the funnel-shaped extension of the opacified subarachnoid space that surrounds each nerve root as it enters its neural foramen. (05 Mar 2000) |
| stilted root | Adventitious aerial roots arising from the trunk and branches, presumably providing support to the plant. (09 Oct 1997) |
| superior root of vestibulocochlear nerve | Radix vestibularis, radix superior nervi vestibulocochlearis, superior root of vestibulocochlear nerve, vestibular root of vestibulocochlear nerve. (05 Mar 2000) |
| sympathetic root of ciliary ganglion | Postganglionic fibres,having cell bodies in the superior cervical ganglion, branching from the carotid plexus passing through the ciliary ganglion without synapse to reach the eyeball. Synonym: radix sympathica ganglii ciliaris. (05 Mar 2000) |
