Q

Why is it difficult to identify and repair spinal cord damage

A

Consists of 31 pairs of nerves each of which have many nerve fibres
Spinal cord is 1.5cm in diameter
Therefore identifying and repairing damage to an individual nerve fibre without damaging others is extremely difficult
Usually lead to permanent loss of function/disability

Q

PARKINSONS

A

Progressive neurodegenerative disorder
Affects movement and motor function
Characterized by symptoms like tremors, rigidity, slowness of movement and postural instability
Caused by the loss of dopamine-producing nerve cells in the brain, particularly in the substantia nigra
Treatment options include medication, deep brain stimulation, and physical therapy
