Spongy bone Spongy bone. Definition. noun. (1) The osseous tissue that fills the interior or cavity of bones with a latticework of small spicules or flat pieces of mineralized bars (trabeculae) and interstices containing bone marrow or fat.(2) The tissue inside of bones that resembles a sponge or a honeycomb with spaces containing bone marrow or fat.Supplement. This type of osseous tissue lies subjacent to the compact bone, and is made distinct by its spongy structure. It is found at the ends of long bones and in the vertebrae.It has low density and strength but has high surface area that allows room for blood vessels and marrow.his type of osseous tissue lies subjacent to the compact bone, and is made distinct by its spongy structure.

Epithelium Study Guide 1 A stratified squamous epithelium is quite thick, with squamous cells on the surface overlying deeper layers of taller cells.  2 Cuboidal describes cells that are rather box-shaped, not flattened. 3  Cuboidal epithelial cells typically appear square or rectangular in cross section, with a round, centrally placed nucleus. Stratified signifies two or more layers of epithelial cells. 2  By convention, a stratified epithelium is described according to the shape of cells on its free surface. 3  Regardless of whether the surface cells are squamous, cuboidal, or columnar, the underlying cells are usually cuboidal.

Spherocytosis Spherocytosis is an auto-hemolytic anemia (a disease of the blood) characterized by the production of spherocytes-red blood cells (RBCs), or erythrocytes, that are sphere-shaped, rather than bi-concave disk shaped. Spherocytes are found in hereditary spherocytosis and autoimmune hemolytic anemia.his is caused by a molecular defect in one or more of the proteins of the red blood cell cytoskeleton, including, spectrin, ankyrin, Band 3, or Protein 4.2. Because the cell skeleton has a defect, the blood cell contracts to its most surface-tension efficient and least flexible configuration, a sphere.

- Helicoidal flow. Helicoidal flow is the cork-screw-like flow of water in a meander. It is one example of a secondary flow. Helicoidal flow is a contributing factor to the formation of slip-off slopes and river cliffs in a meandering section of the river.

Simulate a Beautiful Nuclear War Right in Your Browser The simulator is simple: You start with two nation-states that have some factories and some fighters and some bombers and some ICBMs. Over the course of the simulation they go from Defcon 5 down to 1 and ultimately destroy each other in beautiful flashes of vector graphic goodness. There's a lot going on here, and no key in the actual sim. But Swain explained each simple, geometric graphic, and a bit of the simulation's logic, in a thread on Hacker News:

- Hereditary spherocytosis is a disorder of the membrane (the surface) of your red blood cell that causes your red blood cells to be shaped like spheres instead of flat discs. Spherocytosis causes red blood cells tohave difficulty passing through your spleen. complete blood count test will check your red blood cell levels and the number of immature red blood cells you have. A high number of immature red blood cells can indicate hereditary spherocytosis.

- Now you know that the earth is a spheroid (which is another word for ellipsoid). As you may have suspected, however, it is not a perfect spheroid. The earth's surface is not perfectly symmetrical, so the semi-major and semi-minor axes that fit one geographical region do not necessarily fit another one.

Spherocytosis Spherocytosis is an auto-hemolytic anemia (a disease of the blood) characterized by the production of spherocytes-red blood cells (RBCs), or erythrocytes, that are sphere-shaped, rather than bi-concave disk shaped. Spherocytes are found in hereditary spherocytosis and autoimmune hemolytic anemia.he misshapen but otherwise healthy red blood cells are mistaken by the spleen for old or damaged red blood cells and it thus constantly breaks them down, causing a cycle whereby the body destroys its own blood supply (auto-hemolysis). The term non hereditary spherocytosis is occasionally used, albeit rarely.

- The earth's shape is a spheroid. Although the earth's shape is technically an ellipsoid, its major and minor axes do not vary greatly. In fact, its shape is so close to a sphere that it is often called a spheroid rather than an ellipsoid. A spheroid is simply an ellipsoid that approximates a sphere. These examples are two common world spheroids used today with their values rounded to the nearest meter.

Sporophyte: Definition & Examples Spores are haploid reproductive cells. Remember, a sporophyte is a diploid organism, so in order to produce haploid cells with half the number of chromosomes, meiosis must occur. Meiosis is a type of cell division that cuts the number of chromosomes in a cell in half. In sporophytes, it occurs in structures called sporangia (sporangium is singular). Once spores are produced in a sporangium, they are often released into the air. A single haploid spore will undergo mitosis, or cell division without a reduction in chromosome number, to become a multicellular haploid gametophyte.
