Lordotic Curve

Kyphosis

excessive outward curvature of the thoracic spine.

Scoliosis

lateral curvature of the spine.

lordosis

a condition characterized by excessive inward curvature of the spine, particularly in the lumbar region.

Annulus Fibrosis

The tough outer layer of an intervertebral disk that surrounds the soft inner core

Spondylolisthesis

A condition where one vertebra slips forward over the one below it.

Burner / Stinger

A nerve injury often seen in contact sports, causing a burning or stinging sensation down the arm (typically affects the brachial plexus).

Intervertebral Disk

A structure between each vertebra that acts as a shock absorber and allows for flexibility in the spine.

Out of all of the spinal segments, which segment is the most commonly injured and why?

C5 and C6- it has a lot of more mobility

Where is the Cervical Spine Located

Neck

Where is the thoracic spine located

Located in the upper and mid-back, between the cervical spine and lumbar spine.

Where is the lumbar spine located

Located in the lower back, between the thoracic spine and sacrum.

Vertebrae

Bones of the spine

Nucleus Pulposus

The gel-like inner part of an intervertebral disc, providing cushioning and flexibility.

Vertebral Arch

The bony arch that extends from the posterior side of the vertebral body of a vertebra

Vertebral Body

The large, block-like, anterior portion of a vertebra that bears most of the weight.

Vertebral Joints

The point where two vertebrae come together. They include intervertebral discs and facet joints.

Regions of the spine

Small spinal bones located in the neck (C1-C7), upper back (T1-T12), and lower back (L1-L5).

Atlas

The first cervical vertebra (C1) that supports the head.

Axis

The second cervical vertebra (C2) that allows the head to rotate.
