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.
For typical liver mitochondria, the area of the inner membrane is about 5x as large as the outer membrane due to cristae. This ratio is variable and mitochondria from cells that have a greater demand for ATP, such as muscle cells, contain even more cristae.he inner membrane of mitochondria is similar in lipid composition to the membrane of bacteria. This phenomenon can be explained by the endosymbiont hypothesis of the origin of mitochondria as prokaryotes internalized by a eukaryotic host cell.
