Henlen.

Brit.

/ˈhɛnli/, U.S.

/ˈhɛnli/

Origin: From a proper name. Etymon: proper name Henle.

Etymology: < the name of Friedrich Gustav Jakob Henle, German anatomist and pathologist (1809–85).With Henle's layer n. at sense 1a compare German Henlesche Schicht (1848 or earlier). With Henle's sheath n. at sense 1b compare German Wurzelscheide von Henle root sheath of Henle (1850 or earlier). With sense 2 compare German Henlesche Schleife loop of Henle, Henlesches Röhrchen little tube of Henle, and Henlesche schleifenförmige Röhre loop-shaped tube of Henle (all 1863 or earlier). With Henle's gland n. at sense 1c compare German Henlesche Schleimdrüse mucous gland of Henle (1871 or earlier, with reference to the gall bladder) and Henlesche Drüse gland of Henle (1873 or earlier, with reference to the conjunctiva).

Histology.

1. In the genitive and with of, designating structures described by the German anatomist F. G. J. Henle.Many of these structures were described in Henle's Allgemeine Anat. (1841) and Handb. der systematischen Anat. des Menschen (1855–71).

a. Henle's layer n. (also layer of Henle) †(a) (in full fenestrated layer of Henle) the internal elastic lamina, a layer of elastic fibres in the inner coat (intima) of an arterial wall (obsolete); (b) the outer layer of the inner root sheath of a hair follicle.

1850 Med. Times 12 Oct. 388/2 These last named fibres are very similar to the elastic fibres which form the internal longitudinal layer which lies next to the epithelium, separating it from the fenestrated layer of Henle.

1853 G. Busk & T. H. Huxley tr. A. Kölliker Man. Human Histol. I. 177 Inner layer of the inner root-sheath (Huxley's layer);..outer fenestrated layer (Henle's layer) [Ger. Henle's Schicht].

1951 G. R. de Beer Vertebr. Zool. (ed. 2) xiv. 201 In contact with the cuticle of the hair is the cuticle of the sheath, and next outside that are Huxley's layer, Henle's layer, and the main epidermal layer of the sheath.

2012 T. Ganguly & P. Karnik in V. R. Preedy Handbk. Hair in Health & Dis. i. 19 A hallmark of this stage of differentiation is the formation of Henle's layer, observable as a cone above the dermal papilla.

b. Henle's sheath n. (also sheath of Henle) †(a) the outer layer of the inner root sheath of a hair follicle (= Henle's layer n. (b) at sense 1a) (obsolete rare); (b) a layer of delicate connective tissue surrounding a nerve fibre.

1853 Monthly Jrnl. Med. Sci. Mar. 280 It was possible to mistake the open striæ of the hair cuticle..for the netted fibres of Henle's sheath.

1879 Jrnl. Nerv. & Mental Dis. 6 115 Isolated nerve fibres in their course through muscles are seen to be enclosed by a sheath, which Ranvier calls after its discoverer, the sheath of Henle.

1942 O. Larsell Anat. Nerv. 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.

2012 A. G. Engel Myasthenia Gravis & Myasthenic Disorders (ed. 2) i. 3/2 A basement membrane covers the myelinated nerve fibers and Henle's sheath, but not the fibroblasts.

c. Henle's gland n. (also gland of Henle) †(a) any of a small number of mucous glands present in the lining of the gall bladder (obsolete rare); (b) any of a number of gland-like structures in the conjunctiva of the eyelid.

1873 tr. F. A. Kehrer in Boston Med. & Surg. Jrnl. 17 Apr. 397 Abnormal secretion of the mucous glands of the gall-bladder (Henle's glands [Ger. Henle'schen Schleimdrüsen]).

1890 H. D. Noyes Textbk. Dis. Eye 228 In the tarsal conjunctiva are certain follicular cavities formed by irregular involutions of its epithelium which are called the glands of Henle.

1933 E. 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.

2015 K. R. Pine et al. Clin. Ocular Prosthetics ii. 55 Henle's glands in the orbital conjunctiva may be repositioned but remain functional.

2. Designating the hairpin-shaped part of a renal tubule, which descends from the cortex into the medulla and reascends to the cortex. Chiefly in loop of Henle, Henle's loop, and (now rare) looped tube of Henle. [Described by Henle in Abhandl. der königl. Gesellschaft der Wissenchaften zu Göttingen (1862) 10 228.]

2007 M. N. Levy & A. J. Pappano Cardiovascular Physiol. (ed. 9) xii. 227/2 Most of the capillaries arising from the efferent arterioles of juxtamedullary glomeruli form long hairpin loops (vasa recta) that accompany the loops of Henle deep into the renal medulla.
