| 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 deformities, congenital | Congenital structural deformities of the upper and lower extremities collectively or unspecified. (12 Dec 1998) |
| 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. Synonym: Leyden-Mobius muscular dystrophy, pelvofemoral muscular dystrophy, scapulohumeral muscular dystrophy. (05 Mar 2000) |
| limb-kinetic apraxia | An inability to make movements or to use objects for the purpose intended. Synonym: cortical apraxia, innervation apraxia, limb-kinetic apraxia. (05 Mar 2000) |
| limb lead | One of the three standard leads (leads I, II, III) or one of the unipolar limb lead's (aVR, aVL, aVF). (05 Mar 2000) |
| limb myokymia | Myokymia present in one or more limbs; various causes, one of the more common being prior plexus radiation. (05 Mar 2000) |
| 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) |
| accessory flexor muscle of foot | <anatomy, muscle> Origin, by two heads from the lateral and medial borders of the inferior surface of the calcaneus; insertion, tendons of flexor digitorum longus; action, assists long flexor; nerve supply, lateral plantar. Synonym: musculus flexor accessorius, musculus quadratus plantae, accessory flexor muscle of foot, caro quadrata sylvii, musculus pronator pedis, plantar quadrate muscle, quadrate muscle of sole. (05 Mar 2000) |
| radial flexor muscle of wrist | <anatomy, muscle> Origin, common flexor origin of the medial condyle of humerus; insertion, anterior surface of the base of the second and most often sending a slip to that of the third metacarpal bone; action, flexes and abducts wrist radialward; nerve supply, median; its tendon travels in its own canal roofed by a layer of the transverse carpal ligament. Synonym: musculus flexor carpi radialis, radial flexor muscle of wrist. (05 Mar 2000) |
| paradoxical flexor reflex | Dorsal flexion of the great toe produced by firm lateral pressure on the calf muscles. Synonym: paradoxical flexor reflex. (05 Mar 2000) |
| groove for tendon of flexor hallucis longus | Groove for tendon of the flexor hallucis longus; a vertical sulcus on the posterior process of the talus continuous with a similar groove on the underside of the sustentaculum tali of the calcaneus. Synonym: sulcus tendinis musculi flexoris hallucis longi. (05 Mar 2000) |
| common flexor sheath | The synovial sheath that surrounds the eight tendons of the superficial and deep flexors of the digits of the hand as they pass through the carpal canal; it is commonly continuous with the digital sheath of the little finger. Synonym: vagina communis musculorum flexorum, ulnar bursa. (05 Mar 2000) |
| musculus biceps flexor cruris | <anatomy, muscle> Origin, long head (caput longum) from tuberosity of ischium, short head (caput breve) from lower half of lateral lip of linea aspera; insertion, head of fibula; action, flexes knee and rotates leg laterally; nerve supply, long head, tibial, short head, peroneal. Synonym: musculus biceps femoris, biceps muscle of thigh, musculus biceps flexor cruris. (05 Mar 2000) |
