A
branch like
- receive info from other neurons and moves it on to the soma
4
Q
What is the role of the soma?
A
known as the cell body
- maintains the neuron
- receives messages from the dendrites
5
Q
What is the role of the axon?
A
is a long tube
- transmit neural info from the soma to another neuron
6
Q
What does myelin sheath do?
A
fatty white substance
insulates the axon and protects it + speeds up transmission
7
