Thorax/spine Flashcards
What are 4 characteristic features of the thoracic spine
vertebral body heart shaped
presence of demi facets (inf and sup costal facets)
transverse costal facets
spinous processes are long and start inferior
where does the superior and inferior costal facets articulate with
heads of the rib
where do the transverse costal articulate with
tubercles on the neck of the rib
which type of vertebrae has a heart shaped vertebral body
thoracic vertebrae
which two joints are unique to the vertebral spine
costovertebral and costotransverse
where does the costo-vertebreal joint articulate with
head of the rib articulates with the superior costal facet of the current vertebrae and the inferior costal facet of the one above
where does the costo-transverse joint articulate with
transverse process of the thoracic vertebrae with the tubercle of the adjacent rib
which ribs have costotransverse joints
all ribs except 11 and 12 as these are floating ribs
what is the 1st cervical spine known as
atlas
what is the second cervical spine known as
axis
give characteristics of the cervical spine
triangular vertebral foreamen
bifid spinous process (splits into 2)
has transverse foreamen (holes in the transverse process)
Which type of vertebrae has large vertebral bodies
lumbar spine
which type of vertebrae has triangular vertebral foramen
lumbar
which type of vertebrae has circular vertebral foramen
cervical
Give characteristics of the lumbar vertebrae
large vertebral bodies
vertebral foramen is triangular in shape
transverse processes are long and slender
articular processes have nearly vertical facets
spinous process are short and broad
Which joints run throughout the whole off the vertebral column
cartilaginous joint (symphysis) between vertebral bodies synovial type joint between the vertebral arches which are formed between the articulate processes from adjacent vertebrae
where are cartilaginous joints found
between vertebral bodies
where are synovial type joints found
between vertebral arches
which ligament runs the length of the vertebral column and covers the vertebral bodies and intervertebral disks
anterior and posterior longitudinal ligaments
what does the ligament flavour connect
laminae of adjacent vertebrae
what ligament connects the laminae of adjacent vertebrae
ligamentum flavum
what does the interspinous ligament connect
the spinous processes of the the adjacent vertebrae
what does the supraspinous ligament connect
the tips of adjacent spinous processes
which ligaments are unique to the thoracic spine
radiate ligament of the head of rib
costotransverse ligament which connects the neck of the rib and transverse process
where does the lateral costo-transverse ligament extend to and from
from transverse process to the tubercle of the rib
where does the superior costo transverse ligament passes from and to
upper boarder of the neck of the rib to the transverse process of the vertebrae above
what are the 3 parts of the sternum
manubrum, body and xiphoid process
what joints are at either side of the jugular notch
sternoclavicular joints
where do the anterior intercostal arteries supply
the superior 5-6 intercostal spaces
the anterior intercostal arteries are branches of which artery
internal thoracic artery (aka internal mammory) which is the 1st part of the subclavian artery
at what point does the internal thoracic artery divide into two terminal branches
the 6th intercostal space
what are the 2 terminal branches of the internal thoracic
musculophrenic and superior epigastric
the intercostal nerves are formed from the ventral rami of ……..
T1-T11
intercostal nerve from T12 is formed from which nerve
subcostal nerve
what do lateral cutaneous branches of the intercostal nerve innervate
skin of the side of the thoracic wall
what do anterior cutaneous branches of the IC nerve innervate
it is the terminal part of the IC nerve and innervates the skin near the midline of the chest
Where does the peritoneal sensory branches of the IC nerve run to
the parietal peritoneum on 7th to 11th IC nerves
