Lösung anzeigen
TESTE DEIN WISSEN

TESTE DEIN WISSEN

What is the function of dendritic spines 

Lösung anzeigen
TESTE DEIN WISSEN

TESTE DEIN WISSEN

What is the function of an axon and most important information about it?

Lösung anzeigen
TESTE DEIN WISSEN

Role in the communication between neurons.

Connected to body by the Axon hillock 

can potentially branch into one or more axon collaterals.

Smallest parts are telodendria or end branches

TESTE DEIN WISSEN

What are the most important facts about cells (of the nervous system)

Lösung anzeigen
TESTE DEIN WISSEN
  • Cells make proteins, which are the building blocks of our body
  • According to Cajal's neuron theory neurons are the nervous systems' functional units (This theory also states that behavior arises through the interaction of discrete cells and that the more neurons an animal has the more complex its behavior is.)

What are the 3 Neurons that exist.

Lösung anzeigen
TESTE DEIN WISSEN
  • Sensory neurons
  • Interneurons
  • Motor neurons.
Lösung ausblenden
TESTE DEIN WISSEN

In what 3 parts can a neuron in all parts of the body be subdivided and how many of them are possible?

Lösung anzeigen
TESTE DEIN WISSEN
  • cell body = soma (serves as the core region of the cell)
  • dendrites (pick up all the information from other cells, many)
  • axon (brings messages to other neurons, ,only one)
