Answer 11

thoracic vertebra

Question 12

vertical disc fibers

Answer 12

cervical vertebra

Question 13

fryettes law one of coupled T/L motion

Answer 13

when the spine is in a neutral position side bending and rotation will occur in opposite directions

Question 14

Fryettes law two of coupled T/L motion

Answer 14

when a spine is in a non-neutral positioning side bending and rotation will occur in the same directions

Question 15

fryettes law 3 of coupled T/L motion

Answer 15

when motions of the spine are coupled, the first planer motion will be the strongest and they will progressively decrease as each additional motion is added on.

both close

Question 26

components of the discs

Answer 26

annulus fibrosus= resist torsion Nucleus pulposus= water like and resists compression

Question 27

anterior chain muscles of the spine

Answer 27

longus colli and psoas

Question 28

posterior chain muscles of the spine

Answer 28

paraspinals, gluts, and hamstrings

Question 29

the movers muscles of the spine

Answer 29

erector spine, rectus abdominus, obliques, glut max, hamstrings

Question 30

the stabilizers of the spine

Answer 30

multifidus, rotators, pelvic floor, diaphragm, Transverse abdominals

Question 31

purpose of the pelvic ring

Answer 31

protection of the pelvic elements Males generate more force through there pelvic because they have a greater surface area from the triangular shape of their sacrum

Question 32

C1 on C2 function

Answer 32

-support the head on the spine encases and protects neural elements -allows for quick motions and -reflective balance and righting reactions

Question 33

C1

Answer 33

has no vertebral body

Question 34

C2

Answer 34

-Peg-like dens projects superiorly from the body into the ring of C1 -Dens is anterior superior to the spinal core and is where rotation of the head occurs

Question 35

occipital-atlanto (OA) joint

Answer 35

altas (C1) and the occipital condyles; where nodding of the head occurs

Question 36

Atanto-Axial (AA) joint

Answer 36

3 total articulations - inferior and superior facets of C1 and C2 - dens and anterior arch in the middle - where head roation occurs

Question 37

tectorial membrane

Answer 37

continuation of the posterior longitudinal ligament, passes over AA and attaches to the floor of the cranial cavity

Question 38

alar ligament

Answer 38

V shape ligament that connects the Dens to the occiput

Question 39

cruciate ligament of the atlas

Answer 39

band aid over the dens and connects dens to C1

Question 40

head forward position

Answer 40

with every inch the head moves forward is equivalent to an extra 100% of the weight of the head

Question 41

the thoracic spine rule

Answer 41

T1-T3- same level T4-T6- 1/2 level below T-T9- Full level below T10- Full level below T11- 1/2 a level below T12- same level

Question 42

posterior longitudial ligament

Answer 42

-posterior to vertebra and discs inside of the spinal canal -becomes thin and weak across the lower lumber segments biomechanically associated with increased disc herniation at L4 and L%

Question 43

spinal segment

Answer 43

the adjacent halves of two vertebra, the disc, contents of the vertebral and intervertebral foramen, the facets, associated ligaments, and associated muscle, fascia, and integument innervated by the spinal nerve
