Neurodevelopment Basics
Cards in this deck (10)
- 1InductionOne tissue (inducer) causes a change in another (responder)
- 2Which modalities can cell signalling use?Contact mediated or distance
- 3What is Signal Transduction?A cascade of biochemical reactions eventually causes transcription factors to translocate to the nucleus and alter gene expression
- 4What is the Organiser?Tissue region that can organise other tissues
Creates an embryonic axis
Releases a soluble neural inducing signal - 5What is Competence?The ability of undifferentiated cells to take on a specific fate
- 6What is Specification?The process guiding a cell to a particular fate
- 7What is Commitment?A measure of how firmly a developing cell adheres to its fate
- 8If the Organiser is absent, what tissue does the ectoderm form?Dermis
- 9Is the signal from the Organiser permissive or instructive?Permissive - neural tissue develops i its presence regardless of other agents
- 10What is the signal used by the Organiser?Bone Morphogenetic Protein (BMP)
