Cards

Term
axial skeleton
Definition
bones of the scull, hyoid bone (anchors tounge, hard to break), vertebral column, sternum ribs
Term
appendicular skeleton
Definition
upper extremetry, pectoral girdle, lower extrimetry, pelvic girdle
Term
vertebral column functions
Definition

supports scull, percotal girdle, upper limbs, thorasic cage

transmits body weight to lower limbs

protects spinal nerves, roots, and meninges

Term
distribution of vertebre
Definition

33 total

7 cervical

12 thorasic

5 lumbar

5 saccral fused into one

1 coccyx (4 vertebre with the lower 3 fused)

Term
ligament
Definition
bone to bone connection
Term
intertransverse ligament
Definition
between transverse processes
Term
ligamentum flavum
Definition
connects laminae of vertebre
Term
interspinus ligament
Definition
between spines
Term
ligamentum nuchae
Definition
area in the cervical region with thickened interspinous ligaments and supraspinous ligaments
Term
supraspinous ligament
Definition
between tips of spines
Term
joint
Definition

covers hayline cartlidge on articular facets

the ones between vertebral arches are freely movable synovial joints

Term
anterior longitudinal ligament
Definition
continous, wide, attached to vertebra vodies and discs
Term
posterior longitudinal ligament
Definition

continous, weak, narrow

attached to posterior discs

Term
interveterbal discs
Definition

1/4 of length of column

thickest in cervical and lumbar where more movement is needed

shock absorption

elasticity allows vertebre to move on eachother

resiliance is lost with age

Term
anulus fibrosus
Definition

peripherial part of an interveterbal disc

fibrocartlidgein concentric sheets

Term
hayline end plate
Definition

aka nucleus pulposus

inner part of an intervetebral disc

permit vertebra rocking

gelatenous in kids and adolescents with lots of water.

as you age water turns into fibrocartlidge.

Term
saccrum
Definition

5 rudimentary vertebre fused

concave anteriorlly

upper border articulates L5

lateral border articulates illiac crest forming the sacroiliac joints

Term
sacroiliac joints
Definition
articulation of saccrum with illiac crest
Term
Ala
Definition
wings on side of saccrum
Term
sacral promonotory
Definition

first sacral bulge

upper margin anterior direction

Term
apex
Definition
line between sacrum and coccyx
Term
coccyx
Definition

4 vertebre fused

articulates with sacrum

1st vertebre is usually not fused though

Term
atlas: unique features, joints formed
Definition

C1

no spine or body

forms alanto-axial joint on inferior surface

forms alanto-occipital joints

Term
alanto axial joints
Definition

two joints formed between the interior surface of the atlas and dens of the axis

synovial joint

Term
alanto occipital joints
Definition

formed by the superior articular facets of the atlas with the occipital condyle

synovial joint

allows head to nod

Term
axis
Definition

C2

bifid spine

body

odontoid process (dens) was once the vertebral body of the atlas that fused with the axis body

makes alanto axial joints with atlas

Term
vertebra promines
Definition

C7

small foramen transversum that only transmits the vertebral vein

small and broad body

long non bifid spine

Term
typical cervical vertebre
Definition

bifid spine

body

superior articular facets

transverse processes

posterior/anterior tubericle

foramen transversum (transmits vertebral artery)

Term
defining features of the thorasic vertebre
Definition

small circular vertebral foramen

medium body

spinous process points down

super articular processes point backwards and lateral

transverse costal facets (except T11 and T12) articulate with tubercles of the ribs

inferior articular processes face forward and medial (exept T12 their lateral)

Term
definine features of the lumbar vertebre
Definition

large vertebral body

long slender transverse processes

superior articulating process medial facing

thick lamina

strong pedicle

short flat projected backwards spinous process

triangular vertebral foramen

inferior process articulation surface faces laterally

Term
main purpose of the spinous process
Definition

posterior

lever that attaches muscles and ligaments

Term
main purpose of the inferior articular processes andfacets and composition
Definition

articulate with superior vertebre below making a synovial joint

articular surface has hayline cartlidge

Term
main purpose of the inferior vertebral notch
Definition

forms intervetebral foramen with superior notch from vertebre below

transmits spinal nerves and blood vessels

where dorsal and ventral nerve roots of a spinal nerve unite

Term
articulation =
Definition
joint
