| Starling's curve | A graph in which cardiac output or stroke volume is plotted against mean atrial or ventricular end-diastolic pressure; with increasing venous return and atrial pressure the output proportionately increases until further increments overload the heart and the output falls. Synonym: Frank-Starling curve. (05 Mar 2000) |

| Starling's hypothesis | The principle that net filtration through capillary membranes is proportional to the transmembrane hydrostatic pressure difference minus the transmembrane oncotic pressure difference; although well established, it is called Starling's hypothesis to distinguish it from Starling's law of the heart. (05 Mar 2000) |
| Starling's law | The energy liberated by the heart when it contracts is a function of the length of its muscle fibres at the end of diastole. Synonym: Starling's law. (05 Mar 2000) |
| Starling's reflex | Tapping the volar surfaces of the fingers causes flexion of the fingers; analogous to Rossolimo's reflex, for the toes. (05 Mar 2000) |
| starling | 1. <ornithology> Any passerine bird belonging to Sturnus and allied genera. The European starling (Sturnus vulgaris) is dark brown or greenish black, with a metallic gloss, and spotted with yellowish white. It is a sociable bird, and builds about houses, old towers, etc. Called also stare, and starred. The pied starling of India is Sternopastor contra. 2. <zoology> A California fish; the rock trout. 3. A structure of piles driven round the piers of a bridge for protection and support; called also sterling. Rose-coloured starling. Origin: OE. Sterlyng, a dim. Of OE. Stare, AS. Staer; akin to AS. Stearn, G. Star, staar, OHG. Stara, Icel. Starri, stari, Sw. Stare, Dan. Staer, L. Sturnus. Cf. Stare a starling. Source: Websters Dictionary (01 Mar 1998) |

| Starling's h. |
the direction and rate of fluid transfer between blood plasma in the capillary and fluid in the tissue spaces depend on the hydrostatic pressure on each side of the capillary wall, on the osmotic pressure of protein in plasma and in tissue fluid, and on the properties of the capillary wall as a filtering membrane.

| Starling's l. |
the energy liberated with each contraction of the heart is a function of the length of the fibers composing its muscular walls; increased preload causes increased end-diastolic volume (or pressure), which increases the force of ventricular contraction. Called also Frank-Starling l. or mechanism.

| Starling's law of intestine |
A law stating that a stimulus within the intestine (i.e., the presence of food) initiates a band of constriction on the proximal side and relaxation on the distal side. This results in a peristaltic wave.
