Retrolisthesis can narrow the size of the spinal canal to allow spinal nerve irritation. The stress on the intervertebral disc as the backward movement of the vertebra occurs creates much stress on the disc which then causes back pain. (See the white arrow for retrolisthesis.) Examination.
Mitochondria provide cells their energy, and since muscle cells require more energy than skin cells, there is more mitochondria.itochondria is the part of cells that generate energy by turning nutrients and oxygen into fuel for the body. Muscle cells need this ability more because they are constantly â¦ working; fat cells do not need it as much.
As a rule, mitochondrial diseases are worse when the defective mitochondria are present in the muscles, cerebrum, or nerves, because these cells use more energy than most other cells in the body.
