The Spermatic Chord
What is the primary motor function of the anterior rami of the thoracic spinal roots?
They innervate the Intercostal muscles
What is the primary motor function of the posterior rami of thoracic spinal roots?
Extension of the Back
What is the primary spinal root that causes extension of the Spine?
The posterior thoracic and lumbar rami
What is the primary spinal root that stimulates respiration?
The Thoracic
What is the primary function of the autochthonous musculature of the back?
Extension of the Back
What is the primary function of the Rectus Abdominis?

The anterior rami of T7 to L1
What nerve innervates the autochthonous musculature of the back?
The posterior rami
What nerve innervates the Rectus Abdominus?
The anterior rami of T7 to L1

Absolutely nothing
What planes are used in the anatomy?
Frontal (coronal), Sagittal and Axial
What surfaces are in contact with a zygopophasyeal joint?
The articular processes of the vertebrae
Where does the annulus fibrosus of the intervertebral disc insert?
In the margins of the Epiphyseal plates
Where is the origin and insertion of the ligamentum flavum?
It spans the space between the laminae of adjacent vertebrae
What are the ligaments between 2 vertebrae?
The Anterior Longitudinal Ligament, the Posterior Longitudinal Ligament, the Ligamentum Flavum, the Interspinous Ligament and the Intertransverse Ligament
What is the function of the Transverse Ligament of the Atlas?
To stabilise the the dens of the axis
Why do the intervertebral discs not just get fucking crushed by the all that goddamn weight?
Because the nucleus pulpous acts as a liquid, is incompressible, and is contained by the annulus fibrosus
What structure stabilises the dens of the axis?
The Transverse Ligament of the Atlas

What type of joint is the Atlanto-axial joint?
Synovial, trochoid
What type of joint is the joint between the vertebrae?
Synovial and amphiarthrosis
What type of joint is the joint between vertebral bodies?
Symphysis
