In anatomy, the term ligament is used to denote three different types of structures:^[1]

1. Fibrous tissue that connects bones to other bones. They are sometimes called "articular ligaments"^[2], "fibrous ligaments", or "true ligaments".

Torso is an anatomical term for the central part of the many animal bodies (including that of the human) from which extend the neck and limbs. It is sometimes referred to as the trunk. The torso includes the thorax and abdomen.

vertebral column (backbone or spine) is a column of 34 vertebrae, the sacrum, intervertebral discs, and the coccyx situated in the dorsal aspect of the torso, separated by spinal discs. It houses the spinal cord in its spinal canal.

The anterior longitudinal ligament is a ligament that runs down the anterior surface of the spine. It traverses all of the vertebral bodies and intervertebral discs.

The posterior longitudinal ligament is situated within the vertebral canal, and extends along the posterior surfaces of the bodies of the vertebræ, from the body of the axis, where it is continuous with the membrana tectoria, to the sacrum.

Intervertebral discs (or intervertebral fibrocartilage) lie between adjacent vertebrae in the spine. Each disc forms a cartilaginous joint to allow slight movement of the vertebrae, and acts as a ligament to hold the vertebrae together.

The ligamenta flava connect the laminæ of adjacent vertebræ, from the axis to the first segment of the sacrum.

They are best seen from the interior of the vertebral canal; when looked at from the outer surface they appear short, being overlapped by the laminæ.

The supraspinal ligament (supraspinous ligament) is a strong fibrous cord, which connects together the apices of the spinous processes from the seventh cervical vertebra to the sacrum; at the points of attachment to the tips of the spinous processes fibrocartilage is

The Nuchal ligament is a fibrous membrane, which, in the neck, represents the supraspinal ligaments of the lower vertebræ.

It extends from the external occipital protuberance and median nuchal line to the spinous process of the seventh cervical vertebra.

A zygapophysial joint (zygapophyseal, or facet joint) is a synovial joint between the superior articular process of one (lower) vertebra and the inferior articular process of the adjacent (higher) vertebra. There are two facet joints in each vertebral motion segment.

Costovertebral articulations -- The articulations of the ribs with the vertebral column may be divided into two sets:

• Articulation of head of rib -- connecting the heads of the ribs with the bodies of the vertebrae.

The Articulations of the Heads of the Ribs (costocentral articulations) constitute a series of gliding or arthrodial joints, and are formed by the articulation of the heads of the typical ribs with the facets on the contiguous margins of the bodies of the thoracic vertebræ
