What is the definition of spindle in science?

Definition. noun, plural: spindles. (1) A collection of minute fibers composed of microtubules, which are prominent during cell division, as mitotic spindle or ”mitotic apparatus”. (2) A specialized innervated muscle structure involved in the reflex action and in proprioception, as muscle spindle.

What does spindle mean in law?

Answer: Spindled is jargon for the process of filing a motion, and filing the notice that the motion will be presented to the court for a hearing. The term spindle is used because the motion and notice papers used to be attached to the clerks file with a needle, or spindle.

What does spindle mean in medical terms?

1. a pin tapered at one end or both ends, or something with this shape. 2. the thin, tapering figure occurring during metaphase of cell division, composed of microtubules radiating from the centrioles and connecting to the chromosomes at their centromeres. Called also mitotic spindle.

What is the correct way of using spindle?

Correct way of using a spindle is to rotate it in a clock wise direction so that more fibres started joining to earlier fiber and getting twisted.

What do spindle fibers look like?

When viewed using a light microscope, the spindle (named after a device used for spinning thread) looks like a hairy, elongated ball originating (in animal cells) from the asters around the centrioles, or from opposite sides of the plant cell.

Where do spindle fibers come from?

Microtubules that form the spindle fibers come from centrosomes, which are organelles located in opposite poles near the nucleus. In mitosis, these filaments form at opposite poles of the cell and meet at the equatorial plane.

What is a spindle on a vehicle?

In an automobile, the wheel spindle, sometimes simply called the spindle, is a part of the suspension system that carries the hub for the wheel and attaches to the upper and lower control arms. Spindles are carried by steering knuckles or uprights.

What is spindle shaft?

Definition. A spindle is a rotating shaft with a fixture for holding a tool (in the case of a milling, grinding, or drilling spindle) or a workpiece (in the case of a turning spindle). The spindle shaft serves as a support, a positioner, and a rotary drive for the tool or workpiece.

How do you spell spindle cell?

a spindle-shaped structure, composed of microtubules, that forms near the cell nucleus during mitosis or meiosis and, as it divides, draws the chromosomes to opposite poles of the cell.

What is spindle shape?

Definition. adjective. Having a shape like a spindle, that is being wide in the middle then tapering at both ends.

What happens if spindle fibers dont form?

Spindle fiber formation occurs but spindle fibers cannot function properly, i.e. they cannot separate the daughter chromosomes in the division process. Chromosomes clump in several areas of the cell rather than along the single metaphase plate. Mitosis is disrupted and growth increases.

How do you identify spindle fibers?

In mitosis, these filaments form at opposite poles of the cell and meet at the equatorial plane. Collectively, they form a spindle-shaped structure, which is widest at the middle then tapers at both ends. The spindle fibers form during prophase.

Where is a spindle located on a car?

A spindle is a part of a vehicles suspension. Tying the wheel and tire into the steering system, the spindle is in the front of the vehicle in most cases; however, some front-wheel drive vehicles also have rear spindles. The spindle pivots between the upper and lower A-frames or on the strut.
