Questions and Answers
- 1.
Where do your spinal nerves come out from?
- A.
Vertebral Foramen
- B.
Intervertebral Foramen
- C.
Vertebral Body
- D.
Lamina
Correct Answer
B. Intervertebral ForamenExplanation
The spinal nerves come out from the intervertebral foramen. This is the opening formed between two adjacent vertebrae, allowing the spinal nerves to exit the spinal cord and travel to different parts of the body. The intervertebral foramen provides a pathway for the nerves to transmit signals and information between the spinal cord and the rest of the body.Rate this question:

In the lumbar region, superior articular facets have a bump called ______?
Correct Answer
Mamillary BodiesExplanation
The superior articular facets in the lumbar region have a bump called mamillary bodies. These structures are located on the posterior aspect of the vertebrae and serve as attachment sites for ligaments and muscles. The mamillary bodies help to stabilize and support the spine, contributing to its overall strength and function.Rate this question:

A nerve root is the same thing as saying a spinal nerve where it exits the vertebral column.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because a nerve root is indeed the same as a spinal nerve where it exits the vertebral column. The nerve roots are the initial segments of the spinal nerves that emerge from the spinal cord and pass through the intervertebral foramina. These nerve roots then join together to form the spinal nerves, which carry sensory and motor information to and from different parts of the body. Therefore, it can be concluded that a nerve root and a spinal nerve at their exit points are essentially the same thing.Rate this question:

All deep muscles of the back are supplied by the dorsal rami.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the deep muscles of the back, including the erector spinae muscles, are indeed supplied by the dorsal rami. The dorsal rami are branches of the spinal nerves that innervate the deep muscles and the skin of the back. These nerves provide sensory and motor functions to the deep muscles, allowing for movement and sensation in the back. Therefore, the correct answer is true.Rate this question:

The erector spinae has one common inferior tendon. Where does it attach?
- A.
Iliac Crest
- B.
Thoracic SP
- C.
Lumbar SP
- D.
Sacral SP
- E.
Posterior Sacrum
- F.
Coccyx
Correct Answer(s)
A. Iliac Crest
C. Lumbar SP
D. Sacral SP
E. Posterior SacrumExplanation
The erector spinae is a group of muscles that runs along the length of the spine. It has one common inferior tendon, which means that all the muscles in this group come together to attach to the same point. The correct answer options, Iliac Crest, Lumbar SP, Sacral SP, and Posterior Sacrum, are all possible attachment points for the erector spinae tendon. These options represent different areas along the lower part of the spine where the erector spinae muscles can attach, providing stability and support to the spine. The option Coccyx is not correct because the erector spinae does not attach to the coccyx.Rate this question:

What are the 3 actions of erector spinae? ________, _________, _________ (include direction)
Correct Answer(s)
Extension, ipsilateral Rotation, lateral flexionExplanation
The erector spinae muscles are responsible for extending the spine, rotating it to the same side, and laterally flexing it. Extension refers to the action of straightening the spine, bringing it into a more upright position. Ipsilateral rotation means rotating the spine towards the same side, while lateral flexion involves bending the spine sideways. These actions help to maintain proper posture, stabilize the spine, and enable movements such as bending, twisting, and leaning to the side.Rate this question:
- 11.
What muscles are in the transversospinalis group? ________,_________,________
Correct Answer(s)
multifidus, rotatores, semispinalisExplanation
The correct answer is multifidus, rotatores, and semispinalis. These muscles are part of the transversospinalis group, which is located deep in the back. The multifidus muscle helps to stabilize and extend the spine, while the rotatores muscles aid in rotation and lateral flexion. The semispinalis muscle is responsible for extending and rotating the head and neck. Together, these muscles play a crucial role in maintaining posture and controlling movement in the spine.Rate this question:
- 12.
Which answer is true?
- A.
Semispinalis run TP-SP 4 to 6 above
- B.
Semispinalis run TP-SP 2-4 above
- C.
Multifidus run TP-SP 1-2 above
- D.
Multifidus run TP-SP 4-6 above
- E.
Rotatores run TP-SP 2-4 above
- F.
Rotatores run TP-SP 4-6 above
Correct Answer
A. Semispinalis run TP-SP 4 to 6 aboveExplanation

Transversospinalis muscles rotate the back in the same direction as the erector spine.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Erector spinae rotate ipsilaterally and transversospinalis rotate contralaterally.Rate this question:
-
- 15.
Paravertebral Muscles are the same as the transversospinalis muscles.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the paravertebral muscles and the transversospinalis muscles are indeed the same. These muscles are located alongside the vertebrae and play a crucial role in stabilizing and supporting the spine. They help with movements such as rotation, extension, and flexion of the spine. Therefore, it can be concluded that the paravertebral muscles and the transversospinalis muscles are synonymous terms referring to the same group of muscles.Rate this question:
-
- 16.
Paraspinal muscles are the erector spinae and the transversospinalis groups.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the paraspinal muscles indeed include the erector spinae and the transversospinalis groups. The erector spinae muscles are responsible for extending and straightening the spine, while the transversospinalis muscles aid in rotation and stabilization of the spine. Therefore, both of these muscle groups are part of the paraspinal muscles.Rate this question:

Splenius Capitis has inferior attachments on...
- A.
SP C7-T3
- B.
SP C1-C3
- C.
Nuchal ligament
- D.
TP C7-T3
Correct Answer(s)
A. SP C7-T3
C. Nuchal ligamentExplanation
The correct answer is SP C7-T3, nuchal ligament. The splenius capitis muscle has its inferior attachments on the spinous processes of the vertebrae C7-T3, as well as on the nuchal ligament. These attachments allow the muscle to extend the head and neck, as well as rotate and laterally flex the neck.Rate this question:

- 19.
Splenius Capitis attaches superiorly to the mastoid process.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the splenius capitis muscle does indeed attach superiorly to the mastoid process. The mastoid process is a bony prominence located behind the ear, and the splenius capitis muscle originates from the lower half of the nuchal ligament and the spinous processes of the upper thoracic vertebrae. It then travels upward and laterally to insert onto the mastoid process. This attachment allows the splenius capitis muscle to play a role in extending and rotating the head and neck.Rate this question:
