15. The nervous system Flashcards
What is the function of the nucleus of a neuron?
To provide DNA of cell
What part of the neuron provides the DNA for the cell?
Nucleus
What part of a neuron RECEIVES information FROM other neurons and carry information TOWARDS the cell body
Dendrite
What is the function of a dendrite?
To RECEIVE information FROM other neurons and carry information TOWARDS the cell body
What part of a neuron carries information FROM the cell body TO other neurons?
Axon
What is the function of the axon?
To carry information FROM the cell body TO other neurons
What is the function of an axon terminal?
To stores and secretes neurotransmitters which carry chemical messages to other neurons/cells
What part of a neuron stores and secretes neurotransmitters which carry chemical messages to other neurons/cells
Axon terminal
What is the function of the myelin sheath?
To insulate axon
which increases the rate at which nerve impulses are conducted along the axon
