New cards

Neurogenesis

Birth of new neurons from undifferentiated stem cells.

2
New cards

Plasticity

The capability of neurons to change based on experience, forming new dendrites, synthesizing new proteins, and enhancing synapses.

3
New cards

Regeneration

The ability of neurons to replicate or repair, with limited regeneration capacity.

4
New cards

Regeneration in the CNS

Little to no repair of neurons after damage.

5
New cards

Regeneration in the PNS

Axons and dendrites may undergo repair, provided the cell body is intact, the neurilemma is intact, and Schwann cells are active.

6
New cards

Denervation Atrophy

Muscle wasting or atrophy resulting from the loss of nerve supply, preventing normal muscle function and repair.
