KK: /ˈɛktoʊdɜrm/
The outer layer of cells in an embryo that develops into the skin, nervous system, and some sense organs.
The ectoderm is crucial for the development of the nervous system in vertebrates.
Ectoderm → It is formed from "ecto-" (from Greek "ektos", meaning outside) and "derma" (from Greek "derma", meaning skin). The word "ectoderm" refers to the outermost layer of cells or tissue in an embryo that develops into the skin and nervous system.
Think of 'ecto-' meaning 'outside' and 'derma' meaning 'skin' — this helps you remember that ectoderm is the outer layer of skin in an embryo.
