LAB FINAL Flashcards
ATYPICAL vertebra - whole spine
C spine - C1,C2,C7
thoracic - T1,T9-12
Lumbar = L5
COUPLED MOTIONS
lat flexion and rotation always happen at the same time except C1 C2
upper - ipsi
lower - contra
what SP’s do not have bifid
C1, C7
ligaments of spine ant –> post
ALL
PLL
FLAVUM
INTERSPINIUS
SUPRASPINOUS
MM test deep neck flexors
supine, elbows bent, hands overhead
flexion of cervical spine by lifting head from table
pressure against forehead in posterior direction
serratus posterior superior
SP’s C7-T3 –> superior external border ribs 2-5
serratus posterior inferior
SP’s T11-L3 -> ribs 9-12
what is the attachment site for the 1st rib on the manubrium called
costal notch on
suprasternal / jugular notch
subclavius
1st rib –> middle 1/3 clavicle
nerve to subclavius
depresses and stabilize clavicle
external intercostal fibre direction vs inner and innermost
external - inferiorly and medially
inners - inferiorly and laterally
facet joint
plane
uniaxial
gliding
flex/ext
lat flexion w rotation
intervertebral joint
cartilaginous
symphysis
amphiarthrosis
triaxial
nutation
ant and inferiorly
pelvic outlet enlarges
ischial tuberosities seperate
pubic symp approx
iliac crest approx
PSIS separate
ASIS flare in
what are the 2 pubic ligaments
superior and inferior (arcuate)
external oblique
external surfaces ribs 5-12 –> linea alba, pubic tubercle, ant half iliac crest
internal oblique
ant and mid 1/3 iliac crest, lat 2/3 inguinal ligament
inferior borders ribs 10-12, linea alba, crest of pubis
transverse abdominis
internal surface costal cartilage 7-12 w diaphragm, thoracolumbar fascia, ant 3/4 iliac crest, lat 1/3 inguinal ligament
–>
linea alba
rectus abdominis
pubic crest, pubic symphysis
costal cartilage ribs 5-7, xiphoid process
QL
iliolumbar ligament, iliac crest
inferior border 12th rib, TVP L1-L4
actions of QL
uni - elevates pelvis, lat flexion of trunk, depress 12th rib
bilat - extend lumbar spine - increase lordosis
structure of spinal discs
cervical - thicker ANTERIORLY
thoracic = equal
lumbar - thicker ANTERIORLY
articular surfaces in lumbar spine
superior and inferior articular processes
diaphragm
sternal - 2 slips xiphoid process
costal - inner surface ribs 6-12
bodies of upper lumbar vertebra
central tendon
PRHENIC
superior gemellus
spine of ischium -> medial surface greater trochanter
inferior gemellus
proximal part ischial tuberosity –> medial surface greater trochanter
obturator internus
pelvic surface obturator membrane , pelvic surface ischium –> medial surface greater trochanter
obturator externus
rami of pubis
trochanteric fossa
