What lamina means?

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 meant by plane Lamina?

In mathematics, a planar lamina (or plane lamina) is a figure representing a thin, usually uniform, flat layer of the solid. It serves also as an idealized model of a planar cross section of a solid body in integration.

What is a lamina in mechanics?

Lamina. An object, such as a piece of metal, whose thickness is very small compared to its length and width can be modelled as a lamina. Modelling an object as a lamina means that its mass can be considered to be distributed across a flat surface as it has no thickness.

Is lamina 2D or 3d?

Lamina shapes include 2D figures that can be drawn on a plane, e.g., circle, square, triangle, rectangle, trapezium, rhombus and parallelogram.

What is another name for lamina?

Where are the lamina?

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.

What is difference between plane and lamina?

Plane is a two dimensional figure with limited/ unlimited two dimensions. Lamina is also a two dimensional figure with limited two dimensions. For example a sheet of paper is a lamina.

What is the area of the lamina?

The area of lamina is equal to the sum of the area of complete squares and the area of squares more than the half. Let n be the total number of complete square and more than half or half square. Area of lamina will be nx as area of one big square = 1cm2.

Is lamina a 3D object?

The decoding component of the Lamina 3D display is the laminated volume, where the image encoded by the PDDM is represented by a relief-like 3D image. The relief-like 3D image is a set of voxels located in the outermost part of the object such that each pixel of the image requires only one depth value.

What is uniform lamina?

Definition: A Lamina is a flat, idealized object of uniform thickness. Laminas are so thin that they can be viewed as 2-dimensional plane regions. Laminas have mass/weight even though their thicknesses are negligible.

What is triangular lamina?

The three medians of a triangle are concurrent (meet at a single, unique point) at a point that is two-thirds of the distance from a vertex to the midpoint of the opposite side. Theorem II. The centre of mass of a uniform triangular lamina (or the centroid of a triangle) is at the meet of the medians.

What is moment of inertia of plane lamina?

Statement: The moment of inertia of a plane lamina about an axis perpendicular to its plane is equal to the sum of its moment of inertia about two mutually perpendicular axes concurrent with perpendicular axis and lying in the plane of the laminar body.

What is the Centre of Lamina?

The center of gravity of a lamina is the point that intersects the lines of action of multiple forces that each individually act to suspend the lamina at equilibrium.

What is the Centre gravity of Lamina?

The position of the center of gravity of a rectangular lamina is at the point of intersection of its diagonals.

How do you find the center of gravity of a regular Lamina?

Take a lamina with three holes near the periphery of the lamina, now suspend the lamina through them, one by one. Draw a line of equilibrium for each suspension point. The point of intersection of these three lines would be the centre of gravity.

What is lamina Class 11?

Lamina is the green expanded part of the leaf, it is also known as leaf blade. The important function of the leaf is only performed in lamina like photosynthesis.

What is the another name of leaf blade?

leaf structure …a broad expanded blade (the lamina), attached to the plant stem by a stalklike petiole. In angiosperms leaves commonly have a pair of structures known as stipules, which are located on each side of the leaf base and may resemble scales, spines, glands, or leaflike structures.

What is the difference between lamina and pedicle?

The pedicles help encase the spinal cord and act as a bridge between the vertebral body and the rest of the vertebra. The lamina is attached to the pedicles and completes the circle of protection around the spinal cord.

Is a lamina a disc?

herniated disc: a condition in which disk material protrudes through the disk wall and irritates surrounding nerves causing pain. 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.

Is lamina a bone?

The vertebral laminae: plates of bone that form the posterior walls of each vertebra, enclosing the spinal cord.

What is plane in drawing?

A plane is a two dimensional object having length and breadth only. Its thickness is always neglected. Various shapes of plane figures are considered such as square, rectangle, circle, pentagon, hexagon, etc. PROJECTIONS OF PLANES.

What is plane lamina in technical drawing?

Ans: Plane is a flat surface whereas lamina is a thin flat plate of a larger composite structure. Two-dimensional figures and lamina are assumed to be on a certain plane.

What is the trace of a plane?

TRACES OF PLANES A plane which is not parallel to any of the principal planes will meet the reference planes in a line, extended if necessary. This line is called trace of the plane. Horizontal trace (H.T.) when the plane meets the H.P. in the line, extended if necessary, then that line called horizontal trace.

How do you find the volume of a lamina?

To Measure The Volume Of An Irregular Lamina Using Screw Gauge. The thickness area of the lamina can be determined using a screw gauge, while the surface area of the lamina is measured using graph paper.

What is the difference between area and volume?

The area is the amount of space occupied by a two-dimensional flat object in a plane. Volume is defined as the space occupied by a three-dimensional object.
