The Spinal Cord is a length of nerves that run along the spine and is how nerve signals travel from the brain to the body.
The Spinal Cord is enclosed within the backbone behind the vertabrae.
The Spinal Cord is composed of white matter (the axons of nerve cells) on the outside shell and grey matter (the main nerve bodies) on the inside.

⚜ What is Skin? ⚜
Skin covers the body and helps protects it from the elements and infection.
The outer layer of the skin is made of a protein called Keratin which are skin cells that have died.

The Dermis is a layer of living cells and lies below the Epidermis and Basal layer.

CORTEX
⚜ What is a Cortex? ⚜
The Cortex is the outer layer of organs in the body.
The Cerebral Cortex is the cortex of the brain and surrounds the grey matter.
The Visual Cortex surrounds the lower back area of the brain.
Other Cortex include the Sensory Cortex and the Motor Cortex.
EAR
