Pl. ˈglomera, (erron.) glomi.
[L., = ball of thread.]
†1. Bot. = glomerule 1 a. Obs.
1832J. Lindley Introd. Bot. 111 Suppose the flowers of a simple umbel to be deprived of their pedicels, and to be seated on a receptacle or enlarged axis, and we have a capitulum or head, named glomus by some, glomerulus by others. 1856J. S. Henslow Dict. Bot. Terms 81 Glomus, synonyme for capitulum.
2. Anat. A small body consisting of a plexus of blood-vessels and associated tissue.
a. Applied, chiefly in mod.L. phrases, to various specific structures in the body.
1839–47R. B. Todd Cycl. Anat. III. 635/2 The former are most numerous at that part which was called by the Wenzels glomus, where the choroid plexus turns up from the inferior cornu into the horizontal portion of the lateral ventricle [of the brain]. 1897W. N. Parker tr. Wiedersheim's Compar. Anat. Vertebr. (ed. 2) ix. 341 These vessels become coiled to form a rete mirabile known as the glomus. 1905J. S. Ferguson Normal Histol. xxii. 458 The Carotid Gland. This body.., from its intimate relation to the blood vessels and nerves, is also known as the glomus caroticum. Ibid. 459 The Coccygeal Gland... It is richly supplied with broad capillaries or sinusoids and hence is also known as the glomus coccygeum. 1928G. R. de Beer Vertebr. Zool. xii. 189 Capillaries grow out from the dorsal aorta forming the glomus. 1949A. S. Romer Vertebr. Body xiii. 435 The tails of many mammals (such as dog, cat, rat) show small tissue masses, termed caudal glomeruli, which contain retia mirabilia. 1956W. J. Hamilton Textbk. Human Anat. 315 A chemo⁓receptor is also present in this region [sc. the aortic arch] and constitutes the aortic body, or glomus aorticum. 1962W. H. Hollinshead Textbk. Anat. xxiii. 823/2 Behind the upper end of the common carotid..is a flattened, somewhat ovoid body, the carotid body (glomus caroticum). This is a highly vascular epithelial body that also contains special nerve fibers. 1964J. Mahon tr. Baer's Compar. Anat. Vertebr. 153 This knot of blood vessels forms the glomus or glomerulus, where filtration of the blood occurs. 1965R. P. Morehead Human Path. xxxiv. 1381/2 Tumors of the glomus tympanicum may arise in the middle ear.
b. [named by P. Masson 1924, in Lyon chirurgical XXI. 257.] One of the large number of structures in the skin of the digits in which a special arrangement of muscle and nerve tissue encloses an arterio-venous anastomosis by-passing the capillaries.
1938Physiol. Rev. XVIII. 234 Masson was dissatisfied with the name ‘arteriovenous anastomosis’ because of the confusion with the traumatic and other unusual connections which have received the same name. Since those in the finger often occur in the form of a group which makes a sort of ball, or skein, and since they have a morphology similar to those found in the glomus coccygeum..he adopted the term ‘glomus’... Tumors involving them he termed ‘glomus tumors’ or ‘glomic tumors’. 1950A. W. Ham Histology xxii. 383/1 In the skin of the fingers and toes, and in certain other sites, arteriovenous anastomoses are present in little bodies called glomi that are disposed deep in the dermis. 1962Gray's Anat. (ed. 33) 727 The glomera play an important part in regulating body temperature. 1965R. P. Morehead Human Path. xxii. 580 A glomus tumor is a benign mass of the cutaneous glomus consisting of epithelium-lined spaces surrounded by glomus cells. |
