This vertebral region along with thoracic are considered primary curvatures
What is the sacral region
These structural features of the atlas include the superior and inferior articular parts
What are the lateral masses
the trapezius provides this type of rotation of the head and neck
contralateral
These two regions normally display a lordotic curvature
What are lumbar and cervical
This is the insertion for latissimus dorsi
What is the floor of the intertubercular sulcus or groove
This is the total number of vertebrae in the cervical, thoracic and lumbar spine
What is 24
This bony feature/landmark of the thoracic vertebrae articulates with the tubercle of the rib to form a joint
What is the transverse costal facet?
The origin for this muscle are the posterior tubercles of C1-C4 TVP's
What is levator scapulae
These specific anterior rami will combine to form the lumbosacral plexus
What is L4-S4
The insertion for this muscle is between the angles of the ribs and the tubercles, the mastoid process of the temporal bone and the TVP's in the thoracic and cervical regions
What is longissimus
the posterior longitudinal ligament and this intravertebral disc structure are thinner posteriorly
What is the annulus fibrosus
On the superior surface of the atlas just posterior to the superior articular process is a groove that contains these
What is the vertebral artery and C1 nerve
When Rhomboid major and minor eccentrically contract they assist this type of movement
What is scapular protraction
The anterior rami of T12 will become which nerve
What is the subcostal nerve
These intrinsic back muscles include a brevis and longus part
What are the rotatores
This hooklike extension of the cervical vertebral body is prone to the formation of osteophytes
What is the uncinate process
This vertebral region contains zygapophyseal joints that are oriented vertically in the sagittal plane
What is the lumbar region
These three muscles are considered part of the deep major layer of the intrinsic back muscles
What are semispinalis, multifidus and rotatores
In this type of movement the facet joints become compressed posteriorly with the body on top compressing the intervertebral disc posteriorly
What is extension
This muscle which spans 2-4 vertebral segments and stabilizes the vertebral column along with supporting extension and contralateral rotation is most developed in the lumbar region
What is multifidus
This bony landmark is palpable just inferior to the external occipital protuberance
What is the spinous process of the axis
Starting at this spinal nerve all remaining spinal nerves exit below their respective vertebra
What is the C8 spinal nerve
Which muscles belong to the spinotransversalis group
What are splenius capitis and cervicis
Its name translates into the yellow ligament and extends between adjacent vertebral laminae adding protection to the spinal cord
What is the ligamentum flavum
This muscle does not contribute to the formation of the suboccipital triangle
What is rectus capitis posterior minor
