KP
What type of joint is a DISK?
fibrocartilaginous

20%

the intervertabral foramen.
what is annulus fibrosis?
stronger outter edge of layers of collagen fibers around the spine
what is nucleus pulposis?
water/jelly like inside of the annulus fibrosis, used for shock absorption.
how does the endplate receive nutrition?
via dissufion through the endplates.
where is the anterior longitudinal ligament and what does it do?
thin in cervical spine, thickest in lumbar spine. limits backward bending.
which four ligaments limit forward bending?
posterior longitudinal ligament, ligamentun flavum, interspinous ligament, supraspinous ligament
where is the posterior longitudinal ligament the thinnest?
lumbar spine
which three ligaments limit sidebending?
intertransverse ligaments, ligamentum flavum, capsular ligaments
what is the inguinal ligament?
the groin
what are the names of the three layers of muscle in the posterior back?
superficial, intermediate and deep
what does the superficial layer of posterior back muscles do? example(s)
attachment of lower extremities to trunk, these are key for stabilization.
Ex: trapezius
what does the intermediate layer of the posterior back muscles do? And what is this group of muscles known as?
Errctor spinae. Extend length of spine.
what does the deep layer of the posterior back muscles do? And where do they attach?
Segmental stabilizers. Attach to either transverse or spinous processes. They are for rotation and sidebending.
What are the only two muscles attaching to the anterior spine?
Psoas and diaphram
Rectus Abdominis
Origin is anterior 5th-7th ribs with the insertion on the pubic crest and pubic symphysis. Is the 6 pack.
Linea alba
tendinous connective tissue which lies longitudinally between the two parts of the rectus abdominis muscle.
Rectus Sheath
Surrounds the rectus abdominus, a connective tissue.
External obliques
Origin: 5th-12th ribs. V shaped, attaches to the illiac crest
Internal obliques
Origin is 10th-12th ribs. upside down V shaped, attaches to the illiac crest.
What two muscles create the "natural girdle"?
Thoracolumbar fascia and the transverse abdominis
Are there supraspinous or interspinous ligaments in the cervical spine?
no
