| ureteric bud | The primordial cellular outgrowth from the mesonephric duct that gives rise to the epithelial lining of the ureter, of the pelvis, and calyces of the kidney, and of the straight collecting tubules. Synonym: ureteric bud. (05 Mar 2000) |

| limb bud | The limbs of vertebrates start as outpushings of mesenchyme surrounded by a simple epithelium. The distal region is referred to as the progress zone. There has been extensive study of positional information within the limb bud that determines, for example: the proximal distal pattern of bone development and the anterior posterior specification of digits.

| liver bud | The primordial cellular diverticulum of the embryonic foregut endoderm that gives rise to the parenchyma of the liver. (05 Mar 2000) |
| lung bud | The endodermal lung primordium which will give rise to the epithelial lining of the respiratory tract. Synonym: lung bud. (05 Mar 2000) |
| axillary hair | Hair of the armpit. (05 Mar 2000) |
| bamboo hair | Hair with regularly spaced nodules along the shaft caused by intermittent fractures with invagination of the distal hair into the proximal portion, with intervening lengths of normal hair, giving the appearance of bamboo; seen in Netherton's syndrome; autosomal recessive trait. Synonym: trichorrhexis invaginata. (05 Mar 2000) |
| bayonet hair | A spindle-shaped developmental defect occurring at the tapered end of the hair. (05 Mar 2000) |
| beaded hair | An autosomal dominant trichodystrophy in which brittle hairs show a series of constrictions, usually without a medulla. Synonym: beaded hair, moniliform hair. Origin: L. Monile, necklace, + G. Thrix, hair (05 Mar 2000) |
| bulb of hair | Hair bulb, the lower expanded extremity of the hair follicle that fits like a cap over the papilla pili. Synonym: bulbus pili, hair bulb. (05 Mar 2000) |

| cartilage-hair hypoplasia | An autosomal recessive form of dwarfism characterised by shortness of the extremities without skull defects, and with sparse, brittle hair of light colour. There is a peculiar, not adequately explained severity in the clinical course of varicella and herpes in such patients. (05 Mar 2000) |
| vestibular hair cells | Cell's in the sensory epithelium of the maculae and cristae of the membranous labyrinth of the inner ear; afferent and efferent nerve fibres of the vestibular nerve end synaptically upon them; from the apical end of each cell a bundle of stereocilia and a kinocilium extend into the statoconial membrane of the maculae and the cupula of the cristae. (05 Mar 2000) |
| caterpillar-hair ophthalmia | The presence of nodular swellings on the conjunctiva, due to penetration of ocular tissues by the hairs of caterpillars. Synonym: caterpillar-hair ophthalmia. (05 Mar 2000) |
| medulla of hair shaft | The central axis of some hairs, containing a column of large vacuolated and keratinised cells; the medullary portion is surrounded by the cortex. (05 Mar 2000) |
