Echinocyte 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.

Myocyte A myocyte (also known as a muscle cell) is the type of cell found in muscle tissue. Myocytes are long, tubular cells that develop from myoblasts to form muscles in a process known as myogenesis.There are various specialized forms of myocytes: cardiac, skeletal, and smooth muscle cells, with various properties. The striated cells of cardiac and skeletal muscles are referred to as muscle fibers.ardiomyocytes are the muscle fibres that form the chambers of the heart, and have a single central nucleus. Skeletal muscle fibers help support and move the body and tend to have peripheral nuclei. Smooth muscle cells control involuntary movements such as the peristalsis contractions in the oesophagus and stomach.

Echinoderms Echinoderms are species that belong to the phylum Echinodermata. The phylum contains about 6000 species. Echinoderms get its name from the Greek word which means Spiny Skin, But not all the Echinoderms have spiny skin.

Erythropoiesis â Formation of Red Blood Cells Erythrocytes are derived in the red bone marrow from pluripotent stem cells that give rise to all types of blood cells. Myeloid stem cells are partially differentiated cells that give rise to erythrocytes and several other types of blood cells.

Spur Cell Anemia Differential Diagnoses Echinocytes and keratocytes should be considered in the differential diagnosis of spur cell anemia. Echinocytes or burr cells are spiculated red blood cells with uniform, narrow, spikelike surface projections. Spur cells have fewer spicules, and the spicules vary more in size than echinocytes. Keratocytes are acanthocytelike cells with bizarre shapes and horny projections. Differential Diagnoses.

Echinodermata Class Echinoidea. Echinoids— sea urchins, heart urchins, and sand dollars —are echinoderms without arms and with a spiny shell, or test, formed of tightly fused skeletal plates.The sea urchins (regular echinoids) are hemispherical in shape, round on top and flat on the lower surface.and dollars and heart urchins (irregular echinoids) have a dense covering of short spines, and locomotion is exclusively by movement of the spines. There are two groups of podia-bearing ambulacra, one arranged in a petallike pattern on the upper surface and the other forming a similar pattern on the lower surface.

Background Ectropion is an abnormal eversion (outward turning) of the lid margin away from the globe. Without normal lid globe apposition, corneal exposure, tearing, keratinization of the palpebral conjunctiva, and visual loss may result. Ectropion usually involves the lower lid and often has a component of horizontal lid laxity.

Echinocyte Morphology Echinocyte Morphology. Echinocytes are morphologically altered red blood cells that appear to have numerous, fine, uniform spicules throughout the cell membrane. In mammals, echinocytes have been classified into five main types according to progressive stages in formation and maturation.everal mechanisms of echinocyte formation have been described in the medical literature. Most commonly mentioned is in vitro formation of echinocytes from red blood cell dehydration or expansion of the outer membrane leaflet by amphipathic drugs.

Antigen-presenting cell An antigen-presenting cell (APC) or accessory cell is a cell that displays antigen complexed with major histocompatibility complexes (MHCs) on their surfaces; this process is known as antigen presentation. T cells may recognize these complexes using their T cell receptors (TCRs).

Echinodermata Echinoderms exhibit a type of radial symmetry called pentamerous symmetry in which their body can be divided into five equal parts around a central axis. Echinoderms developed this symmetry after they had already diverged from their bilaterally symmetrical ancestors.chinoderms (Echinodermata) are a group of marine invertebrates that includes star fish, sea lilies, feather stars, brittle stars, sea cucumbers and sea urchins.
