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 costiform is lateral, the mammillary is superior (cranial), and the accessory is inferior (caudal). The mammillary is connected in the lumbar region with the back part of the superior articular process. [clarification needed] The accessory process is situated at the back part of the base of the transverse process. The tallest and thickest ...
The medial arcuate ligament is an arch in the fascia covering the upper part of the psoas major.It is attached to the side of the body of the first or second lumbar vertebra, laterally, it is fixed to the front of the transverse process of the first and, sometimes also, to that of the second lumbar vertebra.
The lateral arcuate ligament is commonly described in anatomy textbooks as attaching at the first lumbar vertebra (L1). [2] However, other instances have been found in cadaver studies with attachments at either the second (L2) or third (L3) lumbar vertebra.
A ligament is the fibrous connective tissue that connects bones to other bones. It also connects flight feathers to bones, in dinosaurs and birds. All 30,000 species of amniotes (land animals with internal bones) have ligaments. It is also known as articular ligament, articular larua, [1] fibrous ligament, or true ligament.
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 lumbosacral ligament or lateral lumbosacral ligament is a ligament that helps to stabilise the lumbosacral joint. The ligament's medial attachment is at (the inferior border of) transverse process of lumbar vertebra L5; its lateral attachment is at the ala of sacrum .
The intertransverse ligaments are weak, sheet-like [1] ligaments interconnecting adjacent transverse processes in the thoracic spine, and adjacent accessory processes in the lumbar spine. They act to limit lateral flexion and rotation of the spine.
