Anything, or any part, corresponding to the toe of the foot; as, the toe of a boot; the toe of a skate. 4. <machinery> The journal, or pivot, at the lower end of a revolving shaft or spindle, which rests in a step. A lateral projection at one end, or between the ends, of a piece, as a rod or bolt, by means of which it is moved. A projection from the periphery of a revolving piece, acting as a cam to lift another piece. <medicine> Toe biter, a morbid condition of the foot in which the toe is depressed and the heel elevated, as in talipes equinus. See Talipes. Origin: OE. Too, taa, AS. Ta; akin to D. Teen, G. Zehe, OHG. Zeha, Icel. Ta, Sw. Ta, Dan. Taa; of uncertain origin. 60. Source: Websters Dictionary (01 Mar 1998) |
| toe clonus | Alternating movements of flexion and extension of the great toe following forcible extension at the metatarsophalangeal joint. (05 Mar 2000) |
| toe-crack | See: sand-crack. (05 Mar 2000) |
| toe-drop | Inability to dorsiflex the toes, usually due to paralysis of the toe extensor muscles. (05 Mar 2000) |
| toe itch | Cutaneous larva migrans caused by larvae of hookworms. Synonym: ancylostoma dermatitis, ancylostomiasis cutis, coolie itch, dew itch, ground itch, swamp itch, swimmer's itch, toe itch, water itch, water sore. (05 Mar 2000) |
| lateral surface of toe | The lateral surface of a toe. Synonym: facies lateralis digiti pedis. (05 Mar 2000) |
| long extensor muscle of great toe | <anatomy, muscle> Origin, lateral surface of tibia and interosseous membrane; insertion, base of distal phalanx of great toe; action, extends the great toe; nerve supply, anterior tibial. Synonym: musculus extensor hallucis longus, long extensor muscle of great toe. (05 Mar 2000) |
| long flexor muscle of great toe | <anatomy, muscle> Origin, lower two-thirds of posterior surface of fibula; insertion, base of distal phalanx of great toe; action, flexes great toe; nerve supply, medial plantar. Synonym: musculus flexor hallucis longus, long flexor muscle of great toe, musculus flexor longus hallucis. (05 Mar 2000) |
| adhesion phenomenon | A phenomenon manifested by the adherence of antigen-antibody-complement complex to "indicator cells" (microorganisms, platelets, leukocytes, or erythrocytes), the reaction being sensitive and specific for the antigen and antibody in the complex. Synonym: erythrocyte adherence phenomenon, immune adherence phenomenon, red cell adherence phenomenon. (05 Mar 2000) |
| AFORMED phenomenon | As induced pulsus alternans progresses, a state in which alternating heart depolarisations fail to eject any blood, thus allowing longer diastolic filling; the subsequent beat is then able to produce a significant ejection; at high rates the cardiac minute volume and blood pressure may appear normal. Origin: Alternating, failure of response, mechanical, to electrical depolarisation (05 Mar 2000) |
| all-or-nothing phenomenon | <physiology> Refers to the phenomenon where the strength of a nerve impulse is not dependent on the strength of the stimulus. Instead, there is a threshold level of stimulus strength that must be reached before the nerve will fire an impulse (at full capacity). Below the threshold, the nerve will not fire at all. <cardiology> It also refers to the same phenomenon observed in the heart muscle, which will either contract fully or not at all. <psychology> In studies of behaviour, it refers to the same phenomenon where a behavioural stimulus will either produce a complete response or no response at all. Also called all-or-nothing principle, all-or-none law, all-or-none responsiveness, etc. (15 Nov 1997) |
| Anrep phenomenon | Homeometric autoregulation of the heart whereby cardiac performance improves as the afterload (aortic pressure) is increased. (05 Mar 2000) |
