Question 2

Question

Answer
  • erector spinae
  • transversospinalis

Question 3

Question
The intrinsic back muscles are supplied by the [blank_start]posterior[blank_end] rami branches at each vertebral level.
Answer
  • posterior
  • anterior

Question 4

Question

Answer
  • True
  • False

Question 5

Question

Question 8

Question
[blank_start]Facet[blank_end] joints are the joints between the superior and inferior articular processes of adjacent vertebrae
Answer
  • Facet

Question 9

Question
What type of joint is a facet joint? (Enter type and subtype) [blank_start]Synovial Plane[blank_end] Joint
Answer
  • Synovial Plane

Question 10

Question
Intervertebral discs are composed of an outer fibrocartilage ring called the [blank_start]annulus fibrosus[blank_end] and an inner soft pulp called the [blank_start]nucleus pulposus[blank_end]
Answer
  • annulus fibrosus
  • nucleus pulposus

Question 11

Question
Ligaments of the Spine: [blank_start]Supraspinous ligament[blank_end] Strong, fibrous tissue connecting the tips of adjacent spinous processes. Kind of like a pole. [blank_start]Interspinous ligament[blank_end] Weak, membranous tissue connecting the superior and inferior surfaces of the spinous processes. Kind of like a curtain.
Answer
  • Supraspinous ligament
  • Interspinous ligament

Question 12

Question

Answer
  • C1
  • C2
  • C3
  • C4
  • C5

Question 13

Question

  • T1
  • T2

Question 15

Question
What is the anatomical location of the start of the spinal cord? The [blank_start]Foramen Magnum[blank_end]
Answer
  • Foramen Magnum

Question 16

Question
Before the cauda equina, the end of the spinal cord is called the [blank_start]conus medullaris[blank_end].
Answer
  • conus medullaris
