Lamella, in cell biology, is also used to describe the leading edge of a motile cell, of which the lamellipodia is the most forward portion. [5] The lipid bilayer core of biological membranes is also called lamellar phase. [6] Thus, each bilayer of multilamellar liposomes and wall of a unilamellar liposome is also referred to as a lamella.
The periosteum is a membrane that covers the outer surface of all bones, [1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline cartilage.)
Lamellae on a gecko's foot. In surface anatomy, a lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between. Aside from respiratory organs, they appear in other biological roles including filter feeding and the traction surfaces of geckos. [1]
This article contains a list of organs in the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming a more common practice [1] [2]); however, there is no universal standard definition of what constitutes an organ, and some tissue groups' status as one is debated. [3]
This is a result of the slippery lamellae sliding past each other when the corpuscle is structurally deformed by external pressure so that effects of sustained pressure are soon dissipated by the lamellae, abolishing deformation of the central axon terminal itself. [8] The capsule thus acts as a physiological high-pass filter. [3]
The lamina propria: a connective tissue layer under the epithelium of an organ. [5] The nuclear lamina: a dense fiber network inside the nucleus of cells. [6] The lamina affixa: a layer of epithelium growing on the surface of the thalamus. The lamina of Drosophila is the most peripheral neuropil of the insect visual system.
They are part of the outer fibrous layer of periosteum, entering into the outer circumferential and interstitial lamellae of bone tissue. Sharpey's fibres also attach muscle to the periosteum of bone by merging with the fibrous periosteum and underlying bone as well.
5. Vas spirale. 6. Zona arcuata, and 6’, zona pectinata of the basilar membrane, with a, its hyaline layer, B, its connective-tissue layer. 7. Arch of spiral organ, with 7’, its inner rod, and 7”, its outer rod. 8 feet (2.4 m) of the internal rods, from which the cells are removed. 9 feet (2.7 m) of the external rods. 10.
