- Description[edit] Each osteon consists of concentric layers, or lamellae, of compact bone tissue that surround a central canal, the haversian canal. The haversian canal contains the bone's blood supplies. The boundary of an osteon is the cement line.

Lamellar structure Lamellar structure. A schematic of a lamellar structure for a eutectic system. Lamellar structures or microstructures are composed of fine, alternating layers of different materials in the form of lamellae. They are often observed in cases where a phase transformation front moves quickly, leaving behind two solid products, as in rapid cooling of eutectic (such as solder) or eutectoid (such as pearlite) systems.

- The question of storage along walls seems to come up a lot. As many of you know, there is an exception for perimeter walls that allows you to forgo the 18-inch clearance between the top of storage shelves and the bottom of sprinkler pendants as long as the perimeter storage isn’t directly below a sprinkler.

What Is Osteon? The osteon, or Haversian system, is the fundamental functional unit of much compact bone. Osteons, roughly cylindrical structures that are typically several millimeters long and around 0.2 mm in diameter. Each osteon consists of concentric layers, or lamellae, of compact bone tissue that surround a central canal, the Haversian canal. The Haversian canal contains the bone’s nerve and blood supplies. Osteoblasts form the lamellae sequentially, from the most external inward toward the Haversian canal.

Their shaped is formed by the rotation movement created to move the cell and they are responsible for spirochete morphology.

It is important that we understand the design and normal structure of fish gills, so lets quickly review the anatomical features of this specialised organ. ‘Branchia’ in Greek means gills and in bony fish (teleosts) = the gills lie in a branchial cavity covered by the bony operculum (gill cover).chematic of the teleost fish gill.

- Zonular lens fibres from the crystalline lens pass deep into the valleys between the ciliary processes. The pars plana is found at the rear most part of the ciliary body, at the taper of its triangular cross-section. At its posterior border it connects with the choroid and abuts the edge of the retina.

- C ells move for a variety of reasons. Bacteria swim by beating their flagella in order to exploit newly created micro-environments and amoeba crawl to gather bacteria to feed on. The cells of vertebrates must move to heal wounds, fend off invaders and the eukaryotic flagella is used to propel sperm cells toward eggs.any cell types in vertebrates adopt a very broad veil-like lamella or pseudopod at the cell front as they advance forward by crawling. This morphology is best illustrated by the keratinocyte where most of the projected surface area is occupied by the lamella (figure 4) (see Lamella expansion).

Intervertebral Discs Annulus Fibrosus and Nucleus Pulposus. Intervertebral discs are composed of an annulus fibrosus and a nucleus pulposus. The annulus fibrosus is a strong radial tire–like structure made up of lamellae; concentric sheets of collagen fibers connected to the vertebral end plates.The sheets are orientated at various angles.he annulus fibrosus encloses the nucleus pulposus. Although both the annulus fibrosus and nucleus pulposus are composed of water, collagen, and proteoglycans (PGs), the amount of fluid (water and PGs) is greatest in the nucleus pulposus. PG molecules are important because they attract and retain water.

Structure of Bone Tissue Compact Bone. Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.Small channels (canaliculi) radiate from the lacunae to the osteonic (haversian) canal to provide passageways through the hard matrix.here are two types of bone tissue: compact and spongy. The names imply that the two types differ in density, or how tightly the tissue is packed together. There are three types of cells that contribute to bone homeostasis.

What is the Haversian System? A Haversian system is a series of concentric circles, called lamellae, found in the compact bone of humans. Compact bone is most often found in the shafts of the long bones of the human skeleton, like those found in the leg. Compact bone is found in the shafts of long bones, and epiphyses are found at the ends. Haversian system, also known as an osteon, is a series of concentric circles, called lamellae, found in the compact bone of humans.

Stentor Cilia mainly cover the rim of the trumpet. In this way, Stentor resemble Vorticella. However, Stentor also have horizontal rows of cilia on the rest of the body to allow it to swim. Contraction and extension are controlled by two longitudinal fiber systems that are found in the cell cortex.

Thylakoid Granum and stroma lamellae. In higher plants thylakoids are organized into a granum-stroma membrane assembly. A granum (plural grana) is a stack of thylakoid discs. Chloroplasts can have from 10 to 100 grana. Grana are connected by stroma thylakoids, also called intergranal thylakoids or lamellae. Grana thylakoids and stroma thylakoids can be distinguished by their different protein composition.
