What's the difference between bulb and corm?

Bulb


Definition:

  • (n.) A spheroidal body growing from a plant either above or below the ground (usually below), which is strictly a bud, consisting of a cluster of partially developed leaves, and producing, as it grows, a stem above, and roots below, as in the onion, tulip, etc. It differs from a corm in not being solid.
  • (n.) A name given to some parts that resemble in shape certain bulbous roots; as, the bulb of the aorta.
  • (n.) An expansion or protuberance on a stem or tube, as the bulb of a thermometer, which may be of any form, as spherical, cylindrical, curved, etc.
  • (v. i.) To take the shape of a bulb; to swell.

  • (5) Dioptric aniseikonia was calculated between 1 month and 24 months after surgery (with Gruber's and Huber's computer program) on the basis of most recently obtained values (bulb axis length, depth of the anterior chamber, lens thickness, necessary refraction), and compared with subjective measurements taken with the phase difference haploscope.
  • (6) This observation provides corroboration for the identification of the principal CCK-I neuron in the rat olfactory bulb as the centrally projecting middle tufted cell.
  • (7) One PCR product hybridized to a 4.0 kb RNA concentrated in subpopulations of putative glutamatergic neurons including mitral cells of the olfactory bulb, pyramidal cells of layer V of the cerebral cortex, pyramidal cells of the piriform cortex, and pyramidal cells of field CA3 of the hippocampus.

  • (10) Olfactory bulbs are relatively smaller in felids than in canids or viverrids.
  • (11) Harvest the bulbs once they reach 7-8cm across; if you cut them off at ground level rather than pulling the whole plant up, the roots should produce a second crop of feathery shoots.

  • (14) The staining of HRP-immunopositive cell bodies indicates that the pallial regions studied receive afferent projections from the main olfactory bulb and are reciprocally interconnected by intrapallial associative fiber systems.
  • (15) The cardiac glycoside ouabain was injected into the eye-bulb of the teleost fish, Carassius carassius.
  • (16) The results also indicate that the two parts of the teleost olfactory bulb are differentiated not only functionally but also morphologically.
  • (17) The rhythmic waves induced by these ions were recorded in the olfactory bulb.
  • (18) In oestrogen-treated preparations, tuberoinfundibular arcuate neurons responsive and unresponsive to accessory bulb stimulation could be distinguished by the frequency of successful antidromic propagation into the soma.
  • (19) The volumetric determination of all those tissues relevant for Opthalmodynamography (ODG) showed the lids to contribute about a quarter to the total volume; another quarter each was due to the optic bulb including optic fascicel, external bulbar musculature and orbital fat.
  • (20) Early resection of carotid body tumors, before involvement of the internal carotid artery and carotid bulb, is advocated.

Corm


Definition:

  • (n.) Same as Cormus, 2.
  • (n.) A solid bulb-shaped root, as of the crocus. See Bulb.

Example Sentences:

  • (1) The stability of various concentrations of morphine sulfate solution stored in Cormed III (Kalex) i.v.
  • (2) The TC1 mRNA accumulates during corm development, is more prevalent in corm apical than basal regions, and is either absent, or present at low concentrations, in other vegetative organs such as the leaf and root.
  • (3) We investigated gene expression patterns that occur during taro corm development.
  • (4) The methods were shown to be sensitive and specific and can be used as an alternative to the pharmacopoeial methods having been applied to the determination of colchicine in corms of Merendera persica and in three pharmaceutical preparations.
  • (5) Our results show that corm development is associated with the differentiation of specialized cells and tissues, and that these differentiation events are coupled with the temporal and spatial expression of corm-specific genes.
