medullary cavity
The intervertebral discs are composed of an outer layer called the annulus fibrosus, which is made of tough fibrous tissue, and an inner gel-like core called the nucleus pulposus. These components provide cushioning and support to the spinal column, allowing for flexibility and shock absorption.
Most of the umbrella mass is a gelatinous material - the jelly - called mesoglea which is surrounded by two layers of protective skin. The top layer is called the epidermis, and the inner layer is referred to as gastrodermis, which lines the gut.

The disks are firm yet compressible. On outer side you have tissue called as annulus fibrosus. On inner side you have soft gelatinous tissue called as nucleus pulposus.

Inner Medulla
The cooler region in a Bunsen flame is called the outer cone or outer mantle. This region is typically blue in color and has a lower temperature compared to the inner cone.
The most dense region of the Earth is called the core. It is divided into the inner core, which is solid due to high pressure, and the outer core, which is molten due to high temperature.
The Medulla is the inner region of a lymph node. It contains B cells, plasma cells, and macrophages.
