Axial Skeleton Flashcards
Vertebral column
C7, T13, L7, S3, Cd 20-23
cervical 7, thoracic 13, lumbar 7, sacral 3, cadual 20-23
interarcual space
between vertebral arches of neighboring vertebrae
flavum ligament
space closed with a short and strong elastic ligament
vertebral canal
wider in cervical and lumbar regions and narrows in thoracic and sacral segments
contains spinal cord, roots of spinal nerves etc
C7
no transverse foramen
vertical pointing spinous process
costal fovea (articulates w rib 1)
thoracic vertebrae
spinous process gives surfaces for epaxial muscles to attach
costal fovea in body
mamillary process
ribs 1-9
true ribs
articulate directly with sternum
ribs 10-13
false ribs
do not articulate with sternum
ribs 13
floating ribs
ventral end do not join with bone or cartilage
manubrium
most cranial portion of sternum, articulate with first costal cartilages
lumbar vertebrae
short spinous process
have mobile synovial joint
transverse processes start to point angle more as go down
atlantooccipital joint
condylar, “yes” joint
between atlas and occipital
atlantoaxial joint
pivot, “no” joint
between atlas and axis
supraspinous lig
joints most dorsal end of all spinous processes except cervical
