Crenation is the loss of water from an animal cell due to osmosis. Lysis is the rupture of the cell wall due to too much water moving into an animal cell due to osmosis. Both â¦crenation and lysis have drastic effects on the animal cell.
Causes of cervical herniated discs. A herniated disc is caused by severe compression in the spine, usually due to general wear and tear or injury. Usually, a herniated disc will either occur in the cervical spine (neck) or lumbar spine (lower back) due to the natural degeneration of the spine over time. The cervical spine is responsible for supporting and stabilizing the head and neck, as well as allowing movement at the pivot point between the head and neck.
