Colloblast Colloblasts are a cell type found in ctenophores. They are widespread in the tentacles of these animals and are used to capture prey. Colloblasts consist of a coiled spiral filament that is embedded in the epidermis and an axial filament with a granular dome.The apical surface of these cells consist of eosinophilic granules that are thought to be the source of adhesion.On contact, these granules rupture, and release an adhesive substance onto the prey. The spiral filament absorbs the impact of the rupture, preventing the ensnared prey from escaping.he apical surface of these cells consist of eosinophilic granules that are thought to be the source of adhesion.

What is the Opposite of Worry? Cultivating a soothing inner voice. This voice, instead of adding fuel to the flames of anxiety, can cool down your anxiety with comforting self-talk, such as, “This is just a temporary mood. 3. Befriending all your emotions. The opposite of worry is learning to welcome and accept every emotion as it arises.

Myeloblast The myeloblast is a unipotent stem cell, which will differentiate into one of the effectors of the granulocyte series. The stimulation by G-CSF and other cytokines triggers maturation, differentiation, proliferation and cell survival. It is found in the bone marrow.

The particles of the dispersed substance are only suspended in the mixture … , unlike a solution, where they are completely dissolved within. colloid is a substance that has tiny particles that do not settle. These particles are large enough to reflect light, therefore the substance's color is shown. An example ma … y be milk because the milk's particles can not be seen individually, but all of them make up a color.

Bone Remodeling They are large, multinucleate cells that form through the fusion of precursor cells. Unlike osteoblasts, which are related to fibroblasts and other connective tissue cells, osteoclasts are descended from stem cells in the bone marrow that also give rise to monocytes.steocytes manufacture type I collagen and other substances that make up the bone extracellular matrix. Osteocytes will be found enclosed in bone. Osteoclasts are bone-resorbing cells (-clast means to break; osteoclasts break down bone).

- Collagen in the Bones. Fibroblasts create the collagen fibers found in our connective tissues, but they are not the only cells that create fibers. Other cells also create the connective tissue fibers found in our bones. In this case, instead of fibroblasts, osteoblasts are laying down new bone fibers.

Fibroblasts The tissue matrix is made almost entirely of collagen, which is the most abundant protein in mammals. Interspersed between the collagen fibers of dense connective tissue, are fibroblasts, which produce a collagen subunit, tropocollagen, which is used to construct larger collagenous aggregates.

Colloid A colloid may be a mixture of one substance that may spread out evenly inside another substance. They may be in two different phases or states of matter. One substance can be the dispersion medium, such as water or gas. The other is kind of dispersed medium, sometimes called the 'internal phase'.

Collagraphy (March 2010) Collagraphy (sometimes spelled collography) is a printmaking process in which materials are applied to a rigid substrate (such as paperboard or wood). The word is derived from the Greek word koll or kolla, meaning glue, and graph, meaning the activity of drawing.

Osteoclast [edit on Wikidata] An osteoclast (from the Greek words for bone (ὀστέον), and broken (κλαστός)) is a type of bone cell that breaks down bone tissue. This function is critical in the maintenance, repair, and remodelling of bones of the vertebral skeleton.

Trophoblast Trophoblasts (from Greek trephein: to feed, and blastos: germinator) are cells forming the outer layer of a blastocyst, which provide nutrients to the embryo and develop into a large part of the placenta. They are formed during the first stage of pregnancy and are the first cells to differentiate from the fertilized egg. This layer of trophoblasts is also collectively referred to as the trophoblast,[1] or, after gastrulation,[2] the trophectoderm, as it is then contiguous with the ectoderm of the embryo.

What do collagen and elastin do? Collagen and elastin are the structure of the skin that maintains both elasticity and firmness. Fibroblast cells create both collagen and elastin matrix that can be activated by glycolic acid and other peels. The special fibroblast cells are found in the papillary level of the second layer of the skin (dermis). Many creams and lotions are marketed to promote collagen formation by fibroblastic activiation.

The Placenta The syncytial trophoblast forms a thin, seamless, and selective barrier between maternal blood and fetal blood. All the critically important nutrients, gases, hormones, electrolytes, and antibodies that pass from mother’s blood to the baby’s blood must travel across this seamless and selective filter.

-       They are triploblastic because they are apart of the phyla Echinodermata. If you look at the animal phylogenetic tree you can see that starfish are apart of … the triploblasts.  The difference between diploblastic and triploblastic is that diploblastic have two germ layers during development which are the ectoderm and endoderm.Triploblastic animals (like starfish, and humans) have three germ layers which are the ectoderm (outside), mesoderm (middle) and endoderm (inside).     They are triploblastic because they are apart of the phyla Echinodermata. If you look at the animal phylogenetic tree you can see that starfish are apart of … the triploblasts.

Histology@ Yale Fibroblasts are by far the most common native cell type of connective tissue. The fibroblast synthesizes the collagen and ground substance of the extracellular matrix. These cells make a large amount of protein that they secrete to build the connective tissue layer. Some fibroblasts have a contractile function; these are called myofibroblasts. Chondrocytes and osteocytes form the extracellular matrix of cartilage and bone. More details and chondrocytes can be found later in this laboratory; osteocytes will be covered in the Laboratory on Bone. The macrophage is the connective tissue representative of the reticuloendothelial, or mononuclear phagocyte, system.
