What's the difference between medullated and myelinated?
Medullated
Definition:
(a.) Furnished with a medulla or marrow, or with a medullary sheath; as, a medullated nerve fiber.
Example Sentences:
(1) Thus these data indicate that although the aortic C-fibres are reset in chronic hypertension, they are reset less than the medullated aortic baroreceptors from the same animal.
(2) Four patients had Gorlin's (or basal cell nevi) syndrome and pronounced medullated nerve fibers.
(3) In 9-week-old undernourished rats, the number and caliber of myelinated fibers were normal while the cross-sectional area of non-medullated fibers was 29% smaller than controls.
(4) The threshold for activation of 54 medullated aortic baroreceptors in the same animals was from 70 to 140 (mean 109) mmHg.
(5) After 6 months the histological examination revealed the presence of newly germinated medullated nerve fibers and motor end plates.
(6) In cross sections of the phrenic nerve 1--2 cm above its entrance into the diaphragm, after an incubation period of 24 hours, 86% of the medullated nerve fibres displayed a high enzyme activity and therefore were classified as motoric.
(7) The mean activity at 100 mmHg was, for the C-fibres 5.0 Hz and for the medullated fibres 34 Hz.

(10) The patient had the typical marfanoid habitus, with thickened lips and alae nasi, neuromas on lips and tongue, medullary carcinoma of the thyroid gland, phaeochromocytomas, and medullated corneal nerve fibres.
(11) The major limitation is a time- and frequency-dependent block of nonmedullated fibers which makes the technique suitable only for differentiating between medullated fibers and nonmedullated fibers with low frequency traffic.
(12) That this inhibition is due to nonmedullated vagal afferents (C fibers) was demonstrated by selective cooling of the vagi, anodal block of medullated afferents, and selective electrical stimulation of medullated and nonmedullated fibers.

(17) In experiments on the isolated aortic arch preparation the electrophysiological characteristics of the aortic baroceptors with the medullated and non-medullated fibres were studied by means of a selective block of conduction in these fibers.
(18) Repetitive stimulation of a single medullated nerve fiber of Xenopus yields a succession of postspike voltage-time curves which are nearly coincident until attainment of a voltage that corresponds to that of the maximum attained by the normal postspike undershoot.
(19) Baroceptors with the non-medullated fibers had a higher threshold pressure and a wider functional range.
(20) The histological studies using electronic microscope showed many non-medullated endings, which were often found beneath the epithelium and in the lamina propria of the villi close to the blood vessels.
