APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -People living with SMA have insufficient levels of the SMN protein, which leads to loss of motor neurons in the spinal cord and causes weakness and wasting of the skeletal muscles.

Detailed explanation-2: -Spinal muscular atrophy (SMA) types 1 through 4 all result from a single known cause-a deficiency of a protein called SMN, which stands for “survival of motor neuron.” Deficiency of SMN protein occurs when a mutation (flaw) is present in both copies of the SMN1 gene-one on each chromosome 5.

Detailed explanation-3: -The first step of SMA is conceptualization, which involves determining who might be harmed and how. If no one is likely to be harmed, then there’s no ethical problem.
