Spindle neuron Wikipedia

Spindle neurons, also called von Economo neurons (VENs), are a specific class of neurons that are characterized by a large spindle-shaped soma (or body), gradually tapering into a single apical axon (the ramification that transmits signals) in one direction, with only a single dendrite (the ramification that receives signals) facing opposite. Other neurons tend to have many dendrites, and the

Muscle spindle Wikipedia

Structure. Muscle spindles are found within the belly of muscles, between extrafusal muscle fibers. The specialised fibers that constitute the muscle spindle are known as intrafusal fibers (as they are present within the spindle), to distinguish themselves from the fibres of the muscle itself which are called extrafusal fibers. Muscle spindles have a capsule of connective tissue, and run

Spindle | Definition of Spindle at Dictionary

Kinesin family member 11 Wikipedia

Kinesin-5 motors assemble into a bipolar homotetrameric structure that is capable of sliding apart bundles of anti-parallel oriented microtubules. This motor is essential for mitosis in most organisms, wherein it participates in the self-assembly of the microtubule-based mitotic spindle, but is not otherwise required for cell viability. The

Spindle definition of spindle by The Free Dictionary

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. 8. a short, turned or circular ornament, as in a baluster or stair rail.

Structural Biochemistry/Mitotic Spindles Wikibooks, open

The mitotic spindle is known as a director that moves chromosomes during mitosis. It is currently unknown how the microtubule fibers move the chromosomes, although it is believed that motor proteins act like carriers moving the chromosomes in different directions.

Muscle Spindle an overview | ScienceDirect Topics

Muscle spindles can be defined as small, spindle-shaped sensory receptors located in skeletal muscle tissue (Fig. 6.11), and they run parallel to the main muscle fibers (extrafusal fibers).A muscle spindle consists of several differentiated muscle fibers (intrafusal fibers) that are enclosed in a spindle-shaped connective tissue sac.

Spinel Wikipedia

Spinel (/ s p ɪ ˈ n ɛ l /) is the magnesium/aluminium member of the larger spinel group of minerals. It has the formula MgAl 2 O 4 in the cubic crystal system.Its name comes from the Latin word "spinella", which means spine in reference to its pointed crystals.
