What is end plate?
What is end plate?
The end plate is a bilayer of cartilage and bone that separates the intervertebral disks from the adjacent vertebrae (Fig. By age 18, the epiphyseal cartilage has thinned and a subchondral bone plate has formed, thus creating the adult end plate bilayer. Simultaneously, the ring apophysis fuses to the vertebral body.
What is sclerosis of the spine?
Narrowing of the intervertebral disc space with sclerosis of the adjacent vertebral bodies may occur as a consequence of infection, neoplasia, trauma, or rheumatic disease. Some patients have been described with backache and these radiological appearances without any primary cause being apparent.
How is the end plate potential generated?
End plate potentials are produced almost entirely by the neurotransmitter acetylcholine in skeletal muscle. Acetylcholine is the second most important excitatory neurotransmitter in the body following glutamate. Acetylcholine is synthesized in the cytoplasm of the neuron from choline and acetyl-CoA.
Where is the end plate?
End-plate potential (EPP), chemically induced change in electric potential of the motor end plate, the portion of the muscle-cell membrane that lies opposite the terminal of a nerve fibre at the neuromuscular junction.
What does it mean to have endplate sclerosis?
A: Endplate sclerosis is a medical term that refers to an increased thickening or density at the top and bottom of a vertebra, which means that the upper and lower endplates of the vertebral body are sunken, hardened and thickened. Endplate sclerosis occurs when the intervertebral disc is enlarged,…
When does osteoarthritis lead to endplate sclerosis?
New transverse bone beams are constantly produced in the vertebral body. When the disc begins to lose fluid, disc degeneration occurs. Disc degeneration often leads to osteoarthritis and endplate sclerosis. Endplate sclerosis commonly occurs in the early stages of osteoarthritis. The extent of endplate sclerosis increases with age.
How long will it take for endplate sclerosis to go away?
Bare with me, this might take a while. So I’ve had a few spine surgeries done over the last couple of years and I can’t remember the last time I sat up straight without thinking about my back. It’s been a pain.
Where are endplates located in the vertebral system?
Endplates are structures present on the top and bottom of each vertebra (except the sacral vertebrae), and are in direct contact with the intervertebral disc. The sclerosis of these endplates is associated with decreased blood supply to these structures.
What is endplate sclerosis and vacuum phenomenon?
The presence of a linear radiolucency in the disk space (vacuum phenomenon) is a typical finding of degenerative disk disease. It is often associated to other findings of degenerative disk disease such as disk space narrowing and endplate sclerosis. Gas in the disk space is rarely associated to disk space infection.
What does endplate changes mean?
Vertebral endplate signal changes (VESC) are more common among patients with low back pain (LBP) and/or sciatica than in people who are not seeking care for back pain. The distribution and characteristics of VESC have been described in people from clinical and non-clinical populations.
What is Spinal endplate sclerosis?
End plate sclerosis is a medical term that refers to an increased thickening or density at the top and bottom of a vertebra. According to Spine-health.com, these end plates attach to intervertebral discs. Vertebra are separated from each other by these discs.
What is endplate sclerotic changes?
The endplates are the cartilage coverings of the upper and lower parts of the vertebral bodies. Schmorls nodes are found commonly and usually are not a cause of pain. Sclerotic changes in the endplate and end plate defects are from wear and tear and sclerosis just means scarring down.
