|
|
vertebrae
|
|
|
neurons
|
|

tissue

Explanation:
Detailed explanation-1: -Paralysis occurs when communication between the brain and spinal cord fails. This can result from injury to neurons in the brain (a stroke), or in the spinal cord.
Detailed explanation-2: -Injuries to the spinal cord disrupt the connections between the brain and spinal-cord neurons, creating motor and sensory deficits in areas of the body below the injury, and sometimes causing paralysis.
Detailed explanation-3: -Both the brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by vertebrae, a set of ring-shaped bones. They’re both cushioned by layers of membranes (called meninges) and cerebrospinal fluid.
