Kinesiology Flashcards
x-axis
Runs medial to lateral
y-axis
Runs superior to inferior
z-axis
Runs anterior to posterior
The anterior longitudinal ligament limits which movement?
Extension
The posterior longitudinal ligament limits which movement?
Flexion
Ligamentum flava
Attaches between adjacent laminae and prevents hyperflexion
Ligamentum nuchae
Attacheds to the spinous processes and serves as muscular attachments.
Interspinal ligament
Attaches to spinous processes and limits flexion and rotation.
Intertransverse ligaments
Attaches to transverse processes and limits lateral flexion and rotation.
Motion of the head is caused mainly by what?
Short contrations which bring the head out of neutral. From there, gravity is the motion creating force.
What controls the motion of the head?
Eccentric contraction of contralateral muscles.
Muslces which are primarily responsible for neck flexion
SCM, longus colli and scalenes
Muslces which are primarily responsible for neck extension
Erector spinae
Ligaments which connect to the dens of the axis
Cruciform and alar
Medial atlantoaxial joint
Formed by the anterior arch of the atlas and the dens of the axis.
