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.
In this electron micrograph, many adjacent mitochondria are visible within the muscle cell. Itâs no coincidence that they are located close to one another â they do that in order to share glucose, amino acids and fatty acids in order to distribute the production of ATP across a coordinately linked network.
