Final answer:
Nerve cells, also known as neurons, are already differentiated and specialized for their roles in the nervous system, with unique structures for transmitting signals. The statement in the question is false.
Step-by-step explanation:
The statement that nerve cells, or neurons, have not yet undergone differentiation is false. Neurons are highly specialized cells that have undergone extensive differentiation. They are characterized by their unique structure, which includes tendrils such as dendrites for receiving signals, and a long axon for transmitting signals to other nerve or muscle cells. Neurons, along with glial cells, make up the nervous tissue and are critical for the computation and communication within the nervous system.
Neurons are electrically active and capable of releasing chemical signals, which are essential for the brain's ability to learn and adapt. While neurons can no longer divide to form new neurons once they are fully differentiated, a process known as neurogenesis allows for the production of new neurons from undifferentiated neural stem cells in the brain, even in adults, though the extent of this is limited.
