This quiz is on the material learned in class on the first part of the vertebral column. (Also contains a little of the sub occipital triangle)

Questions and Answers

1.

What vertebrae can be seen in the middle of the suboccipital triangle?
- A.
  
  C1
- B.
  
  C2
- C.
  
  C3
- D.
  
  C4
Correct Answer
A. C1

Explanation
The vertebrae that can be seen in the middle of the suboccipital triangle is C1, also known as the atlas. The suboccipital triangle is a region located at the base of the skull, formed by the superior oblique, inferior oblique, and rectus capitis posterior major muscles. C1 is the first cervical vertebrae and it articulates with the occipital bone of the skull, allowing for flexion and extension movements of the head.

Rate this question:
2.

Rectus Capitis Posterior Major attaches inferior to the ______ of _____ vertebrae and superior to the _______ _______. (Answer: answer, answer, answer answer) use abbreviations.

Correct Answer
SP, C2, nuchal line

Explanation
The Rectus Capitis Posterior Major muscle attaches inferior to the spinous process (SP) of the second cervical vertebra (C2) and superior to the nuchal line.

3.

Rectus capitis minor attaches to the posterior tuberble of C1 and attaches to the nuchal line.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Rectus capitis minor is a small muscle located at the back of the neck. It originates from the posterior tubercle of the atlas (C1 vertebrae) and inserts into the nuchal line, a ridge on the occipital bone. This muscle is responsible for flexing and rotating the head. Therefore, the statement that Rectus capitis minor attaches to the posterior tubercle of C1 and attaches to the nuchal line is true.

Rate this question:
4.

Which muscle has an attachment on SP C2? (select all that apply)
- A.
  
  Rectus capitis posertior major
- B.
  
  Rectus capitis posterior minor
- C.
  
  Obliquus capitis superior
- D.
  
  Obliquus capitis inferior
Correct Answer(s)
A. Rectus capitis posertior major
D. Obliquus capitis inferior

Explanation
The correct answer is Rectus capitis posertior major and obliquus capitis inferior. These muscles both have an attachment on SP C2.

Rate this question:
5.

What muscle does not attach to the nuchal line.
- A.
  
  Rectus capitis posterior major
- B.
  
  Obliquus capitis superior
- C.
  
  Obliquus capitis inferior
- D.
  
  Rectus capitis posterior minor
Correct Answer
C. Obliquus capitis inferior

Explanation
The obliquus capitis inferior is the correct answer because it does not attach to the nuchal line. The nuchal line is a ridge on the occipital bone of the skull, and the obliquus capitis inferior muscle attaches to the spinous process of the axis vertebra, not the nuchal line.

6.

The artery found in the suboccipital triangle is call the ________ artery.

Correct Answer
vertebral

Explanation
The artery found in the suboccipital triangle is called the vertebral artery.

7.

The suboccipital triangle ______ rotates the head on C1/C2.

Correct Answer
ipsilaterally

Explanation
The suboccipital triangle is a group of muscles located at the base of the skull. These muscles work together to help rotate the head. When the head is rotated ipsilaterally, it means that it is being turned towards the same side as the muscles in the suboccipital triangle. Therefore, the correct answer is "ipsilaterally".

8.

Cervical and Lumbar vertebrae have a ______ curve while thoracic and sacral vertebrae have a _______ curve. (anwser: answer, answer)

Correct Answer
lordotic, kyphotic

Explanation
Cervical and Lumbar vertebrae have a lordotic curve while thoracic and sacral vertebrae have a kyphotic curve. The lordotic curve in the cervical and lumbar regions helps to maintain balance, absorb shock, and provide flexibility in the spine. The kyphotic curve in the thoracic and sacral regions helps to protect the internal organs and provide stability to the spine.

Rate this question:

9.

Cervical curve is also known as a primary curve.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Secondary, you develop when you start picking up your head

Rate this question:
10.

Ventral rami in the thoracic region turn into plexuses.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Ventral rami in the thoracic region don't have plexuses, they just turn into intercostal nerves.

Rate this question:
11.

Spinal cord is the size of the vertebral foramen.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
1/3 the size. rest is filled with fluid and other stuff.

Rate this question:
12.

The _______s and the _______s make up the vertebral arch. (Answer: answer, answer ....alphabetical order)

Correct Answer
lamina, pedicle

Explanation
The lamina and the pedicle are the components that form the vertebral arch. The lamina is a thin, flat plate of bone that extends from the pedicle and forms the posterior portion of the arch. The pedicle, on the other hand, is a short, thick piece of bone that connects the lamina to the body of the vertebra. Together, the lamina and pedicle provide support and protection to the spinal cord, forming the structure of the vertebral arch.

Rate this question:

13.

Spina Bifida is when....
- A.
  
  Spinal cord develops outside the vertebral foramen
- B.
  
  Lamina doesn't close to make spinous process
- C.
  
  Fractured vertebrae
- D.
  
  Vertebrae develops with no transverse processes
Correct Answer
B. Lamina doesn't close to make spinous process

Explanation
Spina Bifida is a congenital condition where the lamina, a part of the vertebra, fails to close properly, resulting in the incomplete formation of the spinous process. This can lead to a range of complications, including the protrusion of the spinal cord and its covering through the gap in the vertebrae. The other options mentioned in the question are not accurate descriptions of Spina Bifida.

Rate this question:
14.

The pars interarticularis is what connects the articular processes. This is same thing as the lamina.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
it is NOT the lamina, it is a separate piece of bone.

Rate this question:
15.

You have one vertebral arch made up of 2 pedicles and 2 laminas.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The vertebral arch is indeed made up of two pedicles and two laminas. The pedicles are short, thick processes that connect the vertebral body to the lamina, which are flat plates of bone that form the posterior portion of the arch. Together, the pedicles and laminas enclose the vertebral foramen, which houses the spinal cord. Therefore, the statement "You have one vertebral arch made up of 2 pedicles and 2 laminas" is true.

Rate this question:
16.

The zygapophysial joint is also known as a facet joint.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement is true because the zygapophysial joint is indeed another term for a facet joint. Facet joints are located in the spine and connect the vertebrae together, allowing for movement and flexibility. They are synovial joints that have cartilage-covered surfaces and a synovial membrane that produces synovial fluid to lubricate the joint. The zygapophysial joint is the specific name for these facet joints in the spine.

Rate this question:
17.

C1 spinal nerve is called C1 and C2 spinal nerve is called C2.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
C2 is called greater occipital nerve but C1 is called the suboccipital nerve.
