|
which sections of the vertebrae are convex anteriorly? |
cervical & lumbar |
|
|
what are the number of cervical, thoracic, lumbar, sacrum, and coccygeal segments? |
C7 T12 L5 S5 (fused into 1) C3-5 (fused into 1) |
|
|
differentiate b/w scoliosis, kyphosis, lordosis |
scoliosis: lateral curvature kyphosis: increased thoracic curvature lordosis: increased lumbar curvature (sway back) |
|
|
which vertebra is the easiest to palpate |
C7 |
|
|
differentiate b/w whiplash, spinal cord injury
|
whiplash: soft tissue damage spinal cord: dislocation of vertebrae |
|
|
what are the prominent landmarks of cervical vertebrae |
bifid spinous process (small neck muscle attachments) transverse foramen (vertebral artery) |
|
|
what is the atlanto-occipital joint
|
articulation b/w atlas and occipital condyles "yes" |
|
|
what is the atlanto-axial joint |
articulation b/w atlas and axis "no" odontoid process of C2 becomes C1's body |
|
|
name important landmarks of the thoracic vertebrae
|
1. very long spinous process 2. transverse costal faces: articulation for tubercle of rib 3. inferior/superior demi facet- forms facet for rib articulation |
|
|
name the important landmarks of lumbar verterbrae |
nothing just short and chunky |
|
|
what is the sacrum? what is a key feature of this bone? |
5 segments fused together pelvic girdle (supports body weight) LANDMARK: anterior sacral promontory |
|
|
coccyx? what are some bony landmarks of the bone? |
tailbone (3-5) segments fused together LANDMARKS 1. sacral canal 2. sacral hiatus |
|
|
name the 4 segments of the abdominal muscles & the functions of them |
1. rectus abdominis: (center of body, primary muscle (6-pack)) **ab pressure, flexion 2. external oblique (pockets) **lat flexion, rotation contralaterally of trunk 3. internal oblique (perpendicular to pockets) **lat flexion, rotation contralaterally of trunk 4. transversus abdominis (deepest ab muscle, weak muscle [L-->R]) **weight belt, poop, ab pressure |
|
|
define tendinous insertions, abdominal aponeuroses, linea alba |
tendinous: segments (don't divide rectus abdominis up) abdominal: fibrous tissue surround muscle linea: connective tissue separating L&R of rectus abdominis |
|
|
what is the common function of the erector spinae group |
uni: lateral flexion of trunk/vertebral column bilaterally: extension |
