Cervical spondylolisthesis occurs when one vertebra in your neck (cervical spine) slips forward or backward relative to the one below it. When this happens at the very bottom of the neck—where C7 overlaps T1—it’s called C7–T1 spondylolisthesis. This misalignment can pinch nerves or the spinal cord, causing pain, numbness, or weakness in your neck, shoulders, arms, or hands Cleveland ClinicPubMed Central.
Anatomy
Structure & Location
The C7 vertebra sits at the base of your neck, just above T1, forming the cervicothoracic junction. Each vertebra has:
Body: the weight-bearing front section
Pedicles & laminae: the “walls” forming the spinal canal
Spinous process: the bony bump you feel at the back of your neck
Facet joints: small joints on the back of each vertebra that guide movement
At C7–T1, the cervical spine’s flexible neck transitions into the rigid upper back Spine-health.
Origin & Insertion
Several muscles attach at C7–T1. For example, the trapezius muscle:
Origin: spinous processes of C7–T12, ligamentum nuchae, and occipital bone UW RadiologyNCBI
Insertion: lateral third of clavicle, acromion, spine of scapula UW RadiologyNCBI
These attachments help move your head, neck, and shoulders.
Blood Supply
Vertebral arteries travel up through openings in the side (“transverse foramina”) of C1–C6; at C7 they usually exit and join to form the basilar artery in your skull.
Segmental cervical arteries branch off the upper back arteries to supply C7–T1 Spine-health.
Nerve Supply
C8 nerve root exits just below C7 and can be compressed if C7 slips on T1.
Dorsal rami (branching from spinal nerves) supply the muscles and skin at this level Spine-health.
Main Functions
Flexion/Extension: bending your head forward and back
Lateral Flexion: tilting your head side to side
Rotation: turning your head left and right
Weight Bearing: supporting the skull’s weight
Protection: shielding the spinal cord and nerve roots
Muscle Attachment: anchoring muscles that move your neck and shoulders Spine-health.
