Meaning and Definition
A dynamic, motile structure at the tip of a developing neuron's axon or dendrite that explores the environment to guide the axon toward its target.
A specialised cellular structure responsible for pathfinding in the developing nervous system; it can refer to the leading edge of any growing cellular process in biology, though this is rare.

FAQ
Frequently Asked Questions
No, it is a highly specialised scientific term used primarily in neuroscience and developmental biology. The average native speaker would not know it.
Absolutely not. Using it in a business context would be incorrect and confusing. Use terms like 'growth area', 'expansion focus', or 'core growth sector' instead.
A growth cone is a temporary, motile structure at the tip of a growing neuron that finds the path. A synapse is the permanent, functional junction between two neurons where communication occurs. The growth cone helps form the synapse.
Not in the standard neuroscientific sense. Plant root tips have a similar exploratory function, but the term 'growth cone' is reserved almost exclusively for neurons. A botanist might use the term analogously in very specific discussions.
A dynamic, motile structure at the tip of a developing neuron's axon or dendrite that explores the environment to guide the axon toward its target.
Growth cone is usually highly technical/scientific in register.
Growth cone: in British English it is pronounced /ˈɡrəʊθ ˌkəʊn/, and in American English it is pronounced /ˈɡroʊθ ˌkoʊn/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Imagine a growing plant's root tip feeling its way through soil; a 'growth cone' is like a root tip for a nerve cell, 'coning' outwards to find its path.
Conceptual Metaphor
THE GROWTH CONE IS A SCOUT/EXPLORER (it probes the environment); THE GROWTH CONE IS A STEERING WHEEL (it directs the axon's growth).
