Anatomy Flashcards
Two types of join in lumbar spine and classification
Intervertebral- synathrosis secondary cartilaginous
Facets- diathrosis triaxial plane joint
Movements and RoM of lumbar spine
Flexion 40-60
Extension 20-35
Sidebend 15-20
Rotation 3-18
Muscles that cause movements in lumbar spine
Flexion- rec abdominus, psoas major and minor, illiacus
Extension- erector spinae, QL, multifidus
Side bend- erector spinae, ext obliques, QL
Rotation- rotatores, multifidus, ext + int obliques, transverse abs
Flat and vertical muscles in abs
Flat- T abs, int + ext obliques
Vertical- rectus abs, pyrimdialis
Features of lumbar vertebrae
Prominent sp
Large triangular foremen
Large kidney shape body
Long tp
90° saggital facets
Typical T spine and their features
T2-8/9
Medium heart shaped body
Circular narrower foramen
Long slender sp points inferior
2 Demi facets uni laterally on the body for rib head
Rough tp because of costal facets for rib tubercle
60° coronal facet orientation
A typical ribs and why they are a typical
T1- one whole facet for rib one and a Demi facet
T10- one entire facet no Demi facets
T11+12- one entire facet and no facet on tp
Typical ribs and features
Rib 3-9
Head-2 Demi facets for vertebrae
Neck- 2 tubercles, articulatory and non
Body- costal groove for nerves and blood vessels
A typical ribs and why
1- only 1 facet- short and thick
2*- normal but thinner and longer
10- only one facet no Demi facets
11+12- whole facet no articular tubercle- floating
Joints and classification in T spine
Costovertebral- synovial plane
Costotransverse- synovial plane
Intervertebral - secondary cartilaginous
Facet- synovial plane 60° coronal
Different rib motions
Rib 1-5 is pump handle- up down
Rib6-10 is bucket handle- up down on arc
Rib11-12 is calliper- out in
Primary and secondary respiratory muscles
Primary- diaphragm
Secondary- intercostal muscles
Movements in T spine and RoM
Flexion 20-45
Extension 25-45
Sidebend 20-40
Rotation- 35-50
Muscles that create movement in t spine
Flexion- rec ab , int + ext obliques
Extension- erector spinae, semispinalis dorsi, QL
Side bend- erector spinae, QL, int obliques
Rotation- erector spinae, int + ext obliques
Typical cerviacal vertebrae and their features
Bifid spinous process
Mid triangular foramen
Small tp with foramen in them
Saddle shaped vertebral body
Atypical c spine and features
C1- no vert body, no sp, anterior tubercle
C2- Aldontoid peg
C7- sp longer and not bifid
Types of joint in c spine and classification
Intervertabral- cartilaginous secondary
Uncovertabral- functional protects vertebral artery
Facets - plane
Atlantoaxial- medial- pivot, lateral- plane.
Atlantooccipital- condyloid
Movements and RoM in cervical
Flexion 50-70
Extension 70-80
Side bend 20-40
Rotation 70-90
Muscles that cause movements in c spine

athrology of elbow- jointts and classification
humoral ulnar joint- uniaxial hinge
radial humeral joint- uniaxial pivot that allows hinge movements
proximal radial ulnar joint- pivot joint
