Meaning and Definition
A fluid-filled cavity that forms in the early embryo during the blastula stage.
Also known as the blastocoel, this is the primary cavity within a blastula, resulting from cell division (cleavage) and providing space for cell rearrangement and the beginning of tissue differentiation in embryonic development.

FAQ
Frequently Asked Questions
While the basic principle is the same, the size and prominence of the segmentation cavity can vary significantly depending on the amount of yolk in the egg (e.g., it is very large in animals with little yolk, like frogs).
It is usually displaced or obliterated during gastrulation when a new cavity, the archenteron (primitive gut), forms.
Yes, though in mammals the equivalent early stage is often called a blastocyst, and the cavity is typically referred to as the blastocyst cavity or blastocoel.
It creates a defined internal space that allows cells to move and reorganise, which is crucial for the next stages of embryonic development like gastrulation.
A fluid-filled cavity that forms in the early embryo during the blastula stage.
Segmentation cavity is usually technical/scientific in register.
Segmentation cavity: in British English it is pronounced /ˌsɛɡ.mənˈteɪ.ʃən ˈkæv.ə.ti/, and in American English it is pronounced /ˌsɛɡ.mənˈteɪ.ʃən ˈkæv.ə.t̬i/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of a segment of an orange forming a hollow space. 'Segmentation' (dividing into segments) creates a 'cavity' (a hollow space) in the early embryo.
Conceptual Metaphor
The embryo as a construction site: the segmentation cavity is the first excavated room or hollow space where further development is organised.
