Study Notes
Neuron Structure and Function
- Dendrites receive signals from other neurons and transmit them to the cell body.
Consequences of Neuron Damage
- Damage to the cell body of a neuron can lead to the death of the neuron.
Neuron Transmission
- The axon is responsible for transmitting information away from the cell body.
Nerve Fibers
- The primary role of nerve fibers (axons) extending from the cell body is to transmit information to other neurons, muscles, or glands.
