Examples of intervertebral disc in the following topics:
-
- Intervertebral discs composed of fibrous cartilage lie between adjacent vertebral bodies from the second cervical vertebra to the sacrum.
- Each disc is part of a joint that allows for some movement of the spine, acting as a cushion to absorb shocks from movements, such as walking and running.
- Intervertebral discs also act as ligaments to bind vertebrae together.
- The inner part of discs, the nucleus pulposus, hardens as people age, becoming less elastic.
-
- Fibrocartilage comprises the intervertebral discs in vertebrate animals, which must withstand a tremendous amount of stress.
-
- Each platelet is disc shaped and 2–4 μm in diameter.
-
- This line, an intercalated disc, assists in passing electrical impulses efficiently from one cell to the next while maintaining the strong connection between neighboring cardiac cells, allowing the cardiac muscle cells to synchronize the beating of the heart.
- Cardiac muscle tissue also has intercalated discs, specialized regions running along the plasma membrane that join adjacent cardiac muscle cells and assist in passing an electrical impulse from cell to cell.
-
- Within the double membrane are stacked, disc-shaped structures called thylakoids.
-
- Cardiac muscle can be
further differentiated from skeletal muscle by the presence of intercalated
discs that control the synchronized contraction of cardiac tissues.
-
- In vertebrates, the notochord develops into the vertebral column or spine: a series of bony vertebrae each separated by mobile discs .
-
- In some nemertine species, another larva specific to the nemertinis, a pilidium, may develop inside the young worm from a series of imaginal discs.
