final 3.0 Flashcards
(31 cards)
how many bones consist of the lumbar, cervical, and thoracic
Lumbar= 5
Cervical=7
Thoracic=12
what do the facet joints articulate with
surface arising from lamina
what is the pars interarticularis
Area connecting superior and inferior facets
which structure is T3 and T7 parallel with
T3 –scapular spine
T7 –inferior angle scapula
which structure is L4 and L5 parallel with
L4—iliac crest
L5—PSIS
is the intervertebral disc’s column anterior or posterior
anterior
is the zygapophyseal joints column anterior or posterior and how many are there at each level
posterior and 2 at each level
what is the anatomy of the intervertebral disc
Annulus fibrosis “cake” Nucleus pulposus “jelly” Vertebral endplates “icing”
true or false
the nuclues pulposus is mostly made of water
true
flexion of the spine causes movement of the disc translation in which direction
posterior
extension of the spine causes movement of the disc translation in which direction
anterior
if the Superior facets face inward & slightly backward are they concave or convex
concave
if the Inferior facets face outward and slightly forward are they concave or convex
convex
does flexion and extension of the spine cause them to open or close and what happens if a person side-bends
Flexion = open Extension = close Side-bend = ipsilateral closes, contralateral opens
what are the ROM at the lumar spine
flexion= 80 degrees extension= 20-30 degrees side-bending= 35 degrees rotation= 45 degrees
define the thoracolumbar fascia
Dense connective tissue envelopes spinal musculature
define nutation and counternutation
nutation= flexion counternutation= extension
what does L-spine/innonimate extension cause at the sacrum
sacral nutation
what does L-spine/innonimate flexion cause at the scarum
sacral counternutation
whats the OIAN of multfidus
O: Sacrum
Transverse processes
I: Spinous processes
A: Extension
Rotation (opposite)
Lateral flexion (same)
IN: Dorsal primary rami of spinal nerves C1-L5
whats OIAN of the transversospinalis
O: Transverse process
I: Spinous process (one above)
A: Extension
Rotation (opposite)
Lateral flexion (same)
IN: Posterior primary rami
what is the meninges made of
Dura mater
Arachnoid mater
Pia mater
Cerebrospinal fluid
what spinal bones the lumbar plexus include and which nerves do they innverate
Spinal nerves T12-L5
Lateral femoral cutaneous
Femoral nerve
Obturator nerve
what spinal bones does the sacral plexus include and which nerves do they innverate
Spinal nerves L4-S3 Superior gluteal nerve Inferior gluteal nerve Tibial nerve Common peroneal nerve
