Neurobiology 1 Flashcards
1
Q
What is a Paramecia?
A
A single celled eukaryote, that does not require neurons for complex movements.
2
Q
What do Paramecia use to move?
A
Cilia and ion channels.
3
Q
What indicates that ion channels and electrical gradients developed very early on in evolution?
A
Prokaryotes have precursor ion channels of a more complex nervous system.
4
Q
Why do large multicellular organisms require direct connections between sensory and motor cells?
A
Because diffusion of chemical transmitters would be too slow and it is difficult to produce specific responses from this.
