Question 1

What do Dendites do?

Answer 1

Recieve inputs from other neurones and convey graded electrical signals passively to the soma

Answer 2

Synthetic and metabolic centre

It contains the nucleus, ribosome, mitochondria and endoplasmic reticulum

Answer 3

Site of initiation of the “all or none” action potential
