| LIM domain | Domain found in proteins required for developmental decisions. Contain 60 residue conserved, cysteine rich, repeats. Named after first 3 genes in group: Lin 11 (C. Elegans required for asymmetric division of blast cells), IsI 1 (mammalian insulin gene binding enhancer protein), mec 3 (C. Elegans required for differentiation of a set of sensory neurons).

| limb | A leg or arm. A branch of a tree. The upper, free, spreading portion of a corolla or perianth that is connate at the base. (09 Oct 1997) |
| 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.

| limb of helix | A transverse ridge continuing backward from the helix of the auricle, dividing the concha into an upper portion (cymba) and a lower portion (cavity of concha). Synonym: crus helicis, crista helicis, limb of helix. (05 Mar 2000) |
| limb-girdle muscular dystrophy | One of the less well-defined types of muscular dystrophy, probably heterogenous in nature. Onset usually in childhood or early adulthood and both sexes affected. Characterised by weakness and wasting, usually symmetrical, of the pelvic girdle muscles, the shoulder girdle muscles, or both, but not the facial muscles. Muscle pseudohypertrophy, heart involvement, and mental retardation are absent. Variable inheritance.
