[Go] difference between 'anatomical structure' terms?

[David Hill]

Hi Maria,

The first one covers any type of anatomical structure formation, whether 
it is a stable structure or a transient structure, whether it is an 
internal structure or an external structure.
The second one covers the formation of an anatomical structure that 
contributes to the shaping of something that is part of its development. 
Development is considered to be a more stable progression over time.

examples: The formation of a pseudopod in an ameoba would not be 
considered formation involved in morphogenesis because it would not be 
thought of as the formation of an anatomical structure that was part of 
the shaping of the ameoba during its development.

The formation of an axon from a neuron would be considered the formation 
of an anatomical structure involved in morphogenesis because it 
contributes to the creation of the form of the neuron in a developmental 
sense.

Hope this helps!

David
