Listen over the apex. Have the patient quantify the chest pain on a 10-point scale. Massage the right carotid artery (to slow the sinus node). When you hear the heart slow, ask the patient to rate the pain again. A significant decrease in pain with massage is a positive test for angina pectoris.
From Wikipedia, the free encyclopedia. Echinocyte (from the Greek word echinos, meaning 'hedgehog' or 'sea urchin'), in human biology and medicine, refers to a form of red blood cell that has an abnormal cell membrane characterized by many small, evenly spaced thorny projections.A more common term for these cells is burr cells.chinocytes, like acanthocytes, may be found in hyperlipidemia caused by liver dysfunction, but the lipids themselves do not integrate into the membrane. Instead, it is speculated that cell surface receptors on the red blood cells bind with HDL cholesterol which induces the shape change.
An echinoderm is a sea animal that has a hard spiny shell, or exoskeleton. Echinoderms display radial symmetry, having 5 similar body extensions from a central point.  The se â¦ ven classes of echinoderms are brittle stars, basket stars, sea urchins, sand dollars, sea lilies, feather stars, and sea cucumbers.chinoderms have swimming larvae that are bilaterally symmetrical, with left and right sides, but they do not 'develop into' bottom-living adult echinoderms, which are radiall â¦ y symmetrical, often star-shaped. The juvenile (young adult), radial from the start, grows from a group of stem cells within the larva.
