Disc
Disc
Disc (pronounced: /dɪsk/), also spelled disk in some contexts, is a term with various meanings in different fields, but in the medical context, it often refers to the intervertebral discs in the spine. The term originates from the Latin discus, which means a round, flat object.
Anatomy
In anatomy, a disc or disk refers to any flat, round plate-like structure in the body. The most common usage is in reference to the intervertebral disc, which is a fibrocartilaginous pad that serves as a cushion between the vertebrae in the spine.
Intervertebral Disc
The intervertebral disc (pronounced: /ˌɪntərvərˈteɪbəl ˈdɪsk/) is a fibrocartilaginous structure that lies between adjacent vertebrae in the vertebral column. Each disc forms a fibrocartilaginous joint to allow slight movement of the vertebrae and acts as a ligament to hold the vertebrae together.
Disc Disorders
There are several medical conditions related to the disc, such as disc herniation, disc degeneration, and discitis. These conditions can cause pain and limit movement, and they often require medical intervention.
Disc Herniation
Disc herniation (pronounced: /ˈhɜːrniːˈeɪʃən/) is a condition in which a tear in the outer, fibrous ring of an intervertebral disc allows the soft, central portion to bulge out beyond the damaged outer rings.
Disc Degeneration
Disc degeneration is a medical condition that can occur as a natural part of aging, but it can also result from injury. It involves the intervertebral disc losing its integrity, flexibility, and shock-absorbing capabilities.
Discitis
Discitis (pronounced: /dɪsˈkaɪtɪs/) is an infection in the intervertebral disc space that can cause severe pain and swelling.
