Spinal 2 Exam 2 Week 2 Flashcards
How many joints are typically formed at the vertebral body of T12?
Typically 8; ten if the rib ligaments are included.
Which muscle(s) is attached to the vertebral body of T12?
Psoas major and psoas minor
What does the superior tubercle of T12 represent?
The mammillary process of lumbar vertebrae.
What ligaments form the costotransverse joint of the twelfth rib?
The superior costotransverse ligament from T11 and the lumbocostal ligament from L1.
What is the orientation of the inferior articular facets of T12?
They face forward, downward, and lateral.
What muscles attach to the spinous process of T12?
The trapezius, latissimus dorsi, serratus posterior inferior, iliocostalis lumborum, spinalis thoracic, multifidus, rotator longus, rotator brevis and interspinalis.
Which erector spinae muscle is unique in its attachment to the T12 spinous process?
Iliocostalis lumborum
Which muscles attach to the vertebral body of thoracic vertebrae?
Longus Colli, psoas major, and minor.
What accounts for the direction of the lumbar curve?
The vertebral body and intervertebral disc have a greater anterior height than posterior height.
What muscles may attach to a typical lumbar vertebral body?
Psoas major, psoas minor.
What is the name given to ligaments which attach vertebral body to articular process?
Transforaminal ligaments
What ligaments attach the vertebral body to the transverse process?
Corporotransverse ligaments
What is the proposed function of the Hofmann ligaments in the cervical-upper thoracic region?
Resist caudal movement of the dural sac; resist gravitational forces on the dura and cord.
What osseous conditions of lumbar vertebrae facilitate a spinal tap in this region?
Overlap of the laminae, shingling, diminishes; overlap of spinous processes, imbrication, diminishes.
A styloid process occurs with what frequency and as a result of what condition?
7% occurrence as a result of congenital elongation of the lumbar accessory process.
What was believed to be entrapped by the mammillo-accessory ligament?
The medial branch of the dorsal ramus of the lumbar spinal nerve
What muscle(s) attach to the lumbar accessory process?
Longissimus thoracis and intertransversarii
What muscle(s) will attach to the mammillary process?
Multifidis and intertransversarii
What names are given to the condition in which the right zygapophysis of a vertebral couple lies in a plane or position different from the left zygapophysis?
Joint asymmetry or joint tropism
What is the name(s) of the condition when the typical lumbar spinous process increase in length due to the aging process?
Baastrup’s syndrome or “kissing spines”
What ligaments attach to the transverse process of the fifth lumbar vertebra?
The lumbosacral, iliolumbar, mammillo-accessory and intertransverse ligaments.
What is the name given to the congenital condition in which the fifth lumbar spinous process is elongated, the sacrum exhibits spina bifida, and dorsiflexion produces pain?
Knife clasp syndrome
Lumbar spondylosis has not been reported in what groups of individuals?
Fetuses, newborns, rarely in children under five years old, patients who have never walked and in on-erect species.
What is the appearance of a spondylolysis in a lumbar vertebra upon oblique x-ray view.
A collared Scotty dog.
