Superficial/Deep Back Flashcards
Secondary Curvature
cervical
lumbar
Components of cervical vertebra
Body, transverse process, foramen transversairum, pedical, lamina, dens (C2), spinous process
Primary Curvatures of the vertebral column
thoracic
sacral
Components of Thoracic Vertebrae
Vertebral foramen Superior costal facet Inferior costa facet Inferior/Superior articulating process Inferior/superior vertebral notch
Symphyses
secondary cartilaginous joints between bodies of 2 adjacent vertebrae
Anterior longitudinal ligament
Anterior side of vertebral body
Posterior longitudinal ligament
Posterior side of vertebral body
Suprapinous ligament
very posterior tip from spinous process to spinous process
Interspinous ligament
run between adjacent spinous processes
Ligamentum Flavum
connects adjacent laminae
Extrinsic Muscles
trapezius, latissimus dorsi, levator scapulae, rhomboids, serratus posterior superior/inferior
Origin of Splenius Capitus/Cervicis
ligamentum nuchae and spinous processes of C7-T6
Insertion of splenius capitus
mastoid process, superior nuchal line,
insertion of cervicis muscle
posterior tubercules of transverse process of C1-C3(must allow lateral bend, movement of neck)
Innervation of Splenius Capitis and Cervicis
Cap- dorsal rami of middle cervical spinal nerves
Cer- dorsal rami of lower cerv
Superficial layers of intrinsic back muscles
Splenius Capitus
Splenius Cervicis
Rhombiod Major/ Minor
C7-T1 (minor)
T2-5 (major)
Dorsal scapular nerve
Serratus posterior superior
Serratus posterior inferior
Superior- nochal ligament, C7-T3 spinous processes; 2nd and 5th ribs
Inferior- spinous process T11-L2, last 4 ribs
Ventral rami of T1-4 spinal nerves (superior)
Ventral rami of T9-T12 inferior)
Semispinalis capitis
transverse processes of 6-7 thoracic vertebrae, 7th cervical
Dorsal rami of cervical spinal nerves
rotation of head
Innervation of Erector Spinae
dorsal rami of respective spinal nerves in each region
