that is a Biology question. the bony matrix is the principle tissue of mature bones. trabecular bone is spongy bone ,which is less dense than compact bone.
That is called an inverse matrix
The null matrix is also called the zero matrix. It is a matrix with 0 in all its entries.
The Transpose of a MatrixThe matrix of order n x m obtained by interchanging the rows and columns of the m X n matrix, A, is called the transpose of A and is denoted by A' or AT.
First we need to ask what you mean by a matrix equalling a number? A matrix is a rectangular array of numbers all of which might be zero and this is called the zero matrix. We can take the determinant of a square matrix such as a 3x3 and this may be zero even without the entries being zero.
This is a reference to a science fiction movie called The Matrix. In it, people were trapped in a virtual reality world and were really slaves to machines. If you're caught in the matrix, you're trapped in a virtual reality.
The thin bony columns are called trabeculae - flat plates with a lattice-like network of thin, bony columns lined with endosteum.

Spongy bones contain what is called cancellous tissue, which is bone with a spongy or honeycomb appearance. This is where new blood cells are made.This cancellous bone framework is called the erythropoietic framework because it makes new blood cells.
large tubercles and/or increased deposit of bony matrix occur at sites of osteoclasts
vertebra
The trabeculae
It's just a "spongy porous tissue" 6/14/2010 actually its also called the cancellous bone as well.
