Vertebrae
The bodies of the vertebrae within this area are fatter and broader; they have to carry a lot of load.
What are the lumbar vertebrae?
What is the direction of internal muscle torque in a crunch?
what is up and what is flexion?
This muscle of the neck, which is named after the insertions, does contralateral rotation and flexion when activated bilaterally.
What is the sternocleidomastoid?
This ligament is continuous and covers the length of the spine, resisting posterior shear and excessive extension.
What is the anterior longitudinal ligament?
What is an overactive lumbar muscle in lower crossed syndrome?
What is the ES? (iliocostalis and longissimus)
This spinal section has vertebrae which are smaller, and a main function is to support the head.
What is is cervical spine?
In a standing lateral bend exercise, with a weight in your right hand. What is the active oblique muscle and in which direction?
What is left internal and/or external obliques?
Drawing my right shoulder to my left knee is activating which oblique muscles? (think not only muscle name but which side, too)
In standing position, what is the direction of external muscle torque?
What is down what is flexion?
This is the anatomically correct term for the joint between the occipital bone and the atlas.
What is the atlantoocciptical joint?
At the cervical spine, what is the direction of external torque in a crunch and what muscles resist this?
External torque is extension.
Resisting this (flexion) SCM
This back muscle of your lower lumbar region can create lateral flexion when activated unilaterally.
What is the Quadratus lumborum?
(can say lumbar region of ES; iliocostalis and longissiumus)
This muscle not only contributes to lower crossed syndrome when overactive, but can also create anterior lumbar shear.
What is the psoas (Iliopsoas ok!)
This is the anatomical term for the horseshoe off the back of the vertebral body, composed of the pedicle, lamina, and the foramen.
What is the neural arch?
When representing forces in a FBD and assessing the plank, what are the external forces at L4-L5 and in what direction?
Gravity, down, creating an extension torque? (what is gravity, down, creating an extension torque)
One muscle named for cap, or head, and one named for the insertion in the neck, these two muscles extend the neck when activated bilaterally.
What are the splenius capitis and cervicis?
This mechanism of potential injury is a decrease in muscle activation in full spinal flexion, leading to potential anterior shear or lumbar anterior translation.
What is the flexion-relaxation phenomenon?
The spinous processes of this vertebrae section point inferiorly.
What is the thoracic spine?
When representing forces in a FBD of a left side plank, what is the internal force direction, muscle torque direction and what trunk muscles would PROB be active?
What is up?
What is left lateral flexion?
QL, left in and external obliques, left erector spinae
This is an intersegmental muscle of the back that's main 'job' is segmental stability but is also a spinal extensor.
What is the multifidus?
(could also say semispinalis, rotatores, or levatores).
What is a typically tight or overactive cervical muscle in upper crossed syndrome?
What is the sternocleidomastoid?
(also, what is the levator scapulae/upper traps?)
