Ligaments/Soft Tissues

Question 1

C: Transverse ligament

Answer 1

Divides the ring of the atlas into two

Compartments are the anterior dens and the posterior spinal cord

Question 2

C: Alar ligament

Answer 2

Attached either side of the dens
Attached to the medial side of the occiput
Relaxed in extension and taut in flexion
Prevents distraction of C1 and C2

Question 3

C: Apical ligament

Answer 3

From the apex of the dens to the foramen magnum

Question 4

C: Tectorial membrane

Answer 4

Covers odontoid process and its ligaments
It’s continuous with the posterior longitudinal ligament which is found on the internal surface of intervertebral canal
Arises from the surface of the axis attaches to the groove of the occipital bone

Question 5

T/L: Posterior longitudinal ligament

Answer 5

Long
Runs posterior to vertebral bodies and intervertebral discs
Extends from back of sacrum and gradually broadens

Question 6

T/L: Anterior longitudinal ligament

Answer 6

Runs down anterior surface of spine, all vertebral bodies and intervertebral discs on ventral side

Question 7

T/L: Ligamentum flavum

Answer 7

Short but thick ligament
Connects lamina over adjacent vertebrae
Preserves upright posture and assists vertebral column in resuming shape after flexion

Question 8

T/L: Thoracolumbar fascia

Answer 8

Posterior layer - superficial transverse processes erector spinae and attached to spinous processes
Middle layer - between erector spinae and quadratus lumborum attached to transverse tips
Anterior - deep to quadratus lumborum, attached to anterior of transverse processes

Question 9

T/L: Rectus sheath

Answer 9

Anterolateral abdominal wall
Anterior layer - EO & IO
Posterior layer - IO & TA
Layers interlace at midline - linea Alba

Question 10

L: Interspinous ligament

Answer 10

Connects spinous processes of adjacent vertebrae

Question 11

L: supraspinous ligament

Answer 11

Connects tips of adjacent spinous processes
