What is a lamina medical term?
The lamina is the flattened or arched part of the vertebral arch, forming the roof of the spinal canal; the posterior part of the spinal ring that covers the spinal cord or nerves.
Which is called lamina?
The flat and expanded portion of the leaf in its entirety is known as the lamina. In short, the blade of the leaf or the leaf blade is called the lamina of a leaf.
What lamina contains?
The basal lamina consists of a mixture of collagens, laminin (glycoprotein), perlecan (heparan sulphate glycoprotein), entactin (glycoprotein). These proteins can bind to each other to make a highly crosslinked extracellular matrix as shown in this diagram.
What is thin lamina?
A thin layer of bone, membrane, or other tissue. The thinnest recognizable layer of sediment, differing from other layers in color, composition, or particle size. Laminae are usually less than 1 cm (0.39 inches) thick. A very thin layer of material. noun.
Is lamina a bone?
lamina: flat plates of bone originating from the pedicles of the vertebral body that form the posterior outer wall of the spinal canal and protect the spinal cord. Sometimes called the vertebral arch.
What bone has a lamina?
vertebra
The lamina is the part of the vertebra that connects the spinous process and the transverse process.
What is incision of Lamina?
Incisions of lamina means V shaped cuts of leaf balde. Here it refers when leaf blade is has cuts in such a way that these cuts reach upto mibrib of leaf. This is the characteristic of compound leaves.
What is the use of Lamina?
The lamina is the expanded portion or blade of a leaf and it is an above-ground organ specialized for photosynthesis.
What is lamina reticularis?
Clinically, the lamina reticularis is the region of the basement-membrane zone in human large airways that accumulates collagen and leads to the subepithelial fibrosis associated with asthma (7, 8).
What is lamina in biology?
Lamina is a general anatomical term meaning “plate” or “layer”. It is used in both gross anatomy and microscopic anatomy to describe structures. The vertebral laminae: plates of bone that form the posterior walls of each vertebra, enclosing the spinal cord. The laminae of the thalamus: the layers of thalamus tissue.
Is lamina and leaf blade same?
Structure of a Typical Leaf Each leaf typically has a leaf blade called the lamina, which is also the widest part of the leaf. Some leaves are attached to the plant stem by a petiole. Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves.
What is mean by lamina in physics?
A two-dimensional planar closed surface which has a mass and a surface density (in units of mass per areas squared) such that. The center of mass of a lamina is called its geometric centroid. SEE ALSO: Cross Section, Geometric Centroid, Perimeter, Plane Curve, Solid.
Which is the best definition of a lamina?
Definition of lamina 1 : a thin plate or scale : layer 2 : either of two broad, flat plates of bone of a vertebra that is fused with and extends from the pedicle to the median line of the neural arch to form the base of the spinous process and that along with the pedicle forms the posterior part of the vertebral foramen
What is the definition of the lamina basalis?
basal lamina. 1. the layer of the basement membrane lying next to the basal surface of the adjoining cell layer, comprising two layers, the electron-lucent lamina lucida and the electron-dense lamina densa.
Which is a synonym for the term lamina lucida?
2.a term sometimes used as a synonym for lamina lucida. reticular laminaa layer of the basement membrane, adjacent to the connective tissue, seen in some epithelia; it is of variable thickness and is composed of condensed connective tissue with a reticulum of collagen fibers.
What is the definition of a lamin protein?
Also found in: Dictionary, Wikipedia. lamin. n. Any of a class of filamentous proteins that form a meshlike layer inside the nuclear membrane of animal cells and have a variety of functions, including providing mechanical support for the nucleus, organizing chromatin, and regulating DNA replication and transcription.
