The ligamenta flava (sg.: ligamentum flavum, Latin for yellow ligament) are a series of ligaments that connect the ventral parts of the laminae of adjacent vertebrae. They help to preserve upright posture, preventing hyperflexion, and ensuring that the vertebral column straightens after flexion. Hypertrophy can cause spinal stenosis.
The bases of denticulate ligaments arise in the pia mater and are firmly attached to the arachnoid mater and dura mater at the apex. [2] The denticulate ligaments extend across the subarachnoid space between anterior nerve roots and posterior nerve roots, piercing the intervening spinal arachnoid mater to reach the dura.
The elastin on the other hand is a protein that allows for flexibility. These two elements of the nuchal ligament maintain a complex balance which allows the constant weight bearing of the head along with multidirectional movement without damaging the durability of the ligament through over-use/stretching. [6]
The posterior atlantoaxial ligament is a broad, thin membrane attached, above, to the lower border of the posterior arch of the atlas; below, to the upper edges of the laminæ of the axis.
The supraspinous ligament connects the tips of the spinous processes from the seventh cervical vertebra to the sacrum. [1] Superior to the 7th cervical vertebra, the supraspinous ligament is continuous with the nuchal ligament.
ligamentum arteriosum: extra-hepatic portion of the fetal left umbilical vein: ligamentum teres hepatis (the "round ligament of the liver"). intra-hepatic portion of the fetal left umbilical vein (the ductus venosus) ligamentum venosum: distal portions of the fetal left and right umbilical arteries: medial umbilical ligaments
The anterior longitudinal ligament extends superoinferiorly between the basiocciput of the skull and the anterior tubercle of the atlas (cervical certebra C1) superiorly, and the superior part of the sacrum inferiorly; [1] inferiorly, it ends at the sacral promontory. [2]
