Henle Anat.|ˈhɛnlɪ|
The name of F. G. J. Henle (see Henlean a.) used in the possessive and with of adjunct to designate numerous anatomical structures, as: a. Henle's layer (or layer of Henle), a single layer of cubical cells in the inner root sheath of the hair follicle, between Huxley's layer and the outer root sheath. Formerly also called Henle's sheath etc. (cf. sense c).
1853Busk & Huxley tr. Kölliker's Man. Human Histol. I. 186 The outermost layer [of the inner root-sheath of the hair], which alone was formerly known, the inner root-sheath of Henle, is formed of elongated cells without nuclei. 1860G. Buchanan tr. Kölliker's Man. Human Microsc. Anat. 109 (caption) A portion of the root of a dark hair..f. outer fenestrated layer (Henle's layer). 1892H. E. Clark Wilson's Anatomist's Vade Mecum (ed. 11) 70 The inner root-sheath [of a hair] is again divisible into..an outer layer (Henle's sheath). 1970T. S. & C. R. Leeson Histol. (ed. 2) xiii. 263/2 Henle's layer..is a single layer of flattened, clear cells which contain hyaline fibrils.
b. Henle's loop (or loop of Henle), a portion of a uriniferous tubule from where it passes from the cortex of the kidney into the medulla to where it returns into the cortex, also spec. the central part of this where it forms a distinct loop at its deepest point in the medulla. Also called Henle's (looped) tube or Henle's tubule etc.
1867Quain's Elem. Anat. (ed. 7) II. 930 The tubes in question have been designated looped tubes of Henle. 1877W. Turner Introd. Human Anat. II. xi. 785 Each intermediary tube..descends..into the medullary pyramid, where it turns on itself, forms a loop, known as the looped tube of Henle, and reenters the cortex as the ascending limb of the looped tube. 1885[see loop n.1 4 a]. 1890Billings Med. Dict. I. 631/2 Henle's loop, loop of Henle. Ibid., Henle's tubules, looped tubules of Henle. 1970T. S. & C. R. Leeson Histol. (ed. 2) xvi. 374/2 The loop of Henle consists of the straight part of the proximal tubule in the descending limb, a thin segment in descending and ascending limbs, and the straight part of the distal tubule in the ascending limb.
c. Henle's sheath (or sheath of Henle) (see quot. 1942). Cf. sense a.
[1878M. L. Ranvier Lecons Histol. Syst. Nerveux I. x. 159 Nous pouvons vous montrer sous un de ces microscopes des nerfs composés d'un seul tube nerveux qui possèdent une membrane enveloppante; j'appellerai cette membrane, gaîne [= sheath] de Henle, du nom de l'auteur qui l'a découverte. ]1887Buck's Handb. Med. Sci. V. 145/1 The sheath in this form has been named the sheath of Henle (Ranvier). There is a space between the nerve-fibre and the sheath. 1890Billings Med. Dict. I. 631/2 Henle's sheath, a continuation of the fibrous tissue of the perineurium. 1942O. Larsell Anat. Nervous Syst. iv. 48 A delicate sheath of connective tissue fibers, continuous with the endoneurium of the nerve trunk, is intimately associated with and surrounds the neurolemma of most individual peripheral fibers. This is usually called the sheath of Henle.
d. Henle's gland (or gland of Henle), any of numerous gland-like structures in the conjunctiva of the eye-lid (see quot. 1933).
1890Billings Med. Dict. I. 631/2 Henle's glands, short tubular glands said to be found on the palpebral conjunctiva. 1933E. Wolff Anat. Eye & Orbit iii. 105 Henle's ‘Glands’ occur in the palpebral conjunctiva between the tarsal plates and the fornices. They are probably not true glands, but folds of mucous membrane cut transversely. 1961S. Duke-Elder Syst. Ophthalm. II. iii. 115 The epithelial depressions between them were originally described by Henle (1866) as glands (the glands of Henle) and were termed conjunctival crypts by Dubreuil (1908). |
