Tensor



noun
1.
Anatomy. a muscle that stretches or tightens some part of the body.
2.
Mathematics. a mathematical entity with components that change in a particular way in a transformation from one coordinate system to another.
noun
1.
(anatomy) any muscle that can cause a part to become firm or tense
2.
(maths) a set of components, functions of the coordinates of any point in space, that transform linearly between coordinate systems. For three-dimensional space there are 3r components, where r is the rank. A tensor of zero rank is a scalar, of rank one, a vector

n.
A muscle that stretches or tightens a body part.
tensor
(těn’sər, -sôr’)

A structure of quantities arranged by zero or more indices, such as a scalar (zero indices), a vector (one index), or a matrix (two indices), which is invariant under transformations of coordinates.

Any of various muscles that stretch or tighten a body part, as the muscle that acts to tense the soft palate, called the tensor palati.
