Haversianadj.

Brit.

/həˈvəːʃn/, U.S.

/həˈvərʒ(ə)n/

Origin: From a proper name, combined with an English element; modelled on a Latin lexical item. Etymons: proper name Havers , -ian suffix.

Etymology: < the name of Clopton Havers (1657–1702), English physician, who described various structures of the bones and joints in Osteologia Nova (1691) + -ian suffix, after post-classical Latin Haversianus (1720 or earlier).

Anatomy.

1. Haversian gland n. [after post-classical Latin glandula Haversiana (1720 or earlier)] now historical and rare a pad of adipose tissue covered by synovium; (in early use also) a synovial fold.Both of these structures were originally thought to be glands secreting synovial fluid.

ΚΠ

1839 R. Adams in Todd's Cycl. Anat. & Physiol. II. 785/2 The fatty and vascular cellular structure named Haversian gland.

1944 Brit. Med. Jrnl. 12 Feb. 228/2 The fatty pads (Haversian glands) are structurally fit to act as manometers of intra-articular pressure.

2001 S. W. Wiesel & J. N. Delahay Princ. Orthopaedic Med. & Surg. xv. 352/1 In addition, the normal tissues in the floor of the acetabulum, specifically the pulvinar (haversian gland) and the transverse acetabular ligament, further fill the acetabulum.

2. Haversian canal n. any of numerous tiny longitudinal channels, surrounded by concentric lamellae of bone and containing blood vessels and connective tissue, which are present in cortical bone.

1838 Athenæum 1 Sept. 635/2 These tubes are surrounded by concentric lamellæ, exactly as the Haversian canals.

1939 T. L. Green Pract. Animal Biol. iii. 248 The major part of the tooth is composed of dentine, a hard dense substance similar to bone but without Haversian canals.

1996 Canad. Geographic Sept. 71 (caption) The black shapes are Haversian canals, bone channels once round, now crushed flat by eons underground.

2012 C. Crowder & S. Stout Bone Histol. v. 126 It should be possible to distinguish sheep bone from human bone based on the presence of smaller secondary osteons and Haversian canals in sheep.

3. Haversian system n. a Haversian canal and the surrounding lamellae of bone (often considered as a structural unit of bone); = osteon n.

1845 R. B. Todd & W. Bowman Physiol. Anat. I. v. 123 Each Haversian system..has only its small innermost lamella in contact with them [sc. blood-vessels].

1928 S. Moore & J. A. Key tr. R. Leriche & A. Policard Normal & Pathol. Physiol. of Bone i. 24 Histologists have tried to make the Haversian systems the structural units of bone.

1986 D. Koontz Strangers i. ii. 200 An unusual chemical environment in the marrow cavity and in the haversian canals..actually encourages the growth of marrow cells.

2012 C. Crowder & S. Stout Bone Histol. v. 113 The horse femur exhibited rings of Haversian systems alternating with bands of lamellar bone.

4. Haversian fringe n. now rare a fold of synovium, often containing blood vessels and adipose tissue, projecting into the synovial cavity; (also) a small projection from the edge of such a fold; a synovial fold or villus.

ΚΠ

1848 Quain's Elements Anat. (ed. 5) I. p. ccci We may cite the Haversian fringes of the synovial membranes.

1904 G. A. Piersol Normal Histol. (ed. 7) viii. 132 Many of the Haversian fringes contain vascular tufts.

1921 Med. Rec. 12 Feb. 259/2 The..synovial membrane..is a cellular tissue smooth for much of its extent but thrown into folds or villi called Haversian fringes.

5. Haversian lamella n. any of the thin concentric layers of bone surrounding a Haversian canal.

1848 Quain's Elements Anat. (ed. 5) I. p. cxliii This apparently cellular structure..occurs chiefly at the circumference of a series of Haversian lamellae.

1912 J. S. Kingsley tr. R. Hertwig Man. Zool. 78 The Haversian lamellae are concentrically arranged around the lumen of the Haversian canals.

2007 J. C. Stevenson & M. S. Marsh Atlas Osteoporosis (ed. 3) ii. 9/2 Trabecular bone..consists mainly of more fragmented systems of Haversian lamellae.

6. Haversian space n. a space between Haversian systems present during the development and remodelling of bone.

ΚΠ

1852 London, Edinb., & Dublin Philos. Mag. 4 468 These spaces, produced by absorption, are called by the authors [sc. J. Tomes and C. de Morgan] Haversian spaces.

1916 C. Davison & F. D. Smith Autoplastic Bone Surg. iii. 57 The Haversian spaces are formed during the process of dissolution.

2005 L. Solomon et al. Apley's Conc. Syst. Orthopaedics & Fractures (ed. 3) 55/2 Haversian spaces enlarge,..i.e. year by year, the bones become slightly more porous.

7. Haversian fold n. rare a fold of synovium, often containing blood vessels and adipose tissue, projecting into the synovial cavity; cf. Haversian fringe n. at sense 4.

ΚΠ

1876 Quain's Elements Anat. (ed. 8) II. 203 The Haversian folds..agree in general structure with the rest of the tissue of the synovial membrane.

1910 Trans. Sect. Surg. (Amer. Med. Assoc.) 40 The synovial membrane in those places where it is thrown into folds (Haversian folds or fringes) is lined by epithelioid cells.
