A diagram illustrating horizontal integration and contrasting it with vertical integration. Horizontal integration is the process of a company increasing production of goods or services at the same part of the supply chain. A company may do this via internal expansion, acquisition or merger. The process can lead to monopoly if a company captures the vast majority of the market for that product or service. Horizontal integration is orthogonal to vertical integration, where companies integrate multiple stages of production of a small number of production units.
The cortex of the brain which contains nerve cell bodies. The gray matter is in contrast to the white matter, the part of the brain that contains myelinated nerve fibres. The gray matter is so named because it in fact appears gray. The white matter is white because that is the colour of myelin, the insulation covering the nerve fibres.
The cerebral cortex covers the outer portion (1.5mm to 5mm) of the cerebrum. It is the layer of the brain often referred to as gray matter.The cortex (thin layer of tissue) is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white.he cerebral cortex covers the outer portion (1.5mm to 5mm) of the cerebrum.
