The trunk Flashcards
(43 cards)
Sternocostal joint
- what articulates
- function
- sternum and ribs
- slightly mobile and flexible to allow ribcage to expand and contract for breathing
true ribs
1-7
- articulate via costocartilage directly with the sternum
false ribs
8-10
- do not articulate directly with the sternum
floating ribs
11-12
- no anterior connection
what are intervertebral joints seperated by
intervertebral discs
3 paired bones which make up the pelvic girdle
illium
ischium
pubis
what’s the pubic symphysis
midline joint between the 2 pubic bones
3 common structures of a vertebrae bone
- vertebral body (excluding c1)
- vertebral arch
- vertebral foramina (canal)
what’s part of the vertebral arch
- spinous process (excluding c1)
- transverse processes
- articular processes (superior and inferior)
Lordosis and kyphosis what part of the vertebrae is what
cervical - L
thoracic - k
lumbar - L
sacrum & coccyx - K
is the vertabral body front or back
front
are cervical vertebrae big or small
small
are lumbar vertebrae big or small
big
on the 2nd - 6th cervical certainly what’s the spinous process called
bifid process
on c2-6 does it have a big or small foramen (hole)
big
on the cervical what surrounds the transverse foramen
transverse process
on the cervical what is on the transverse process
anterior and posterior tubercles
does the 7th cervical have a bifid spinous process
no
does the 7th cervical have a transverse foramen
yes
what’s different about the cervial vertebrae
- spinous process is split into 2 (bifid process)
- big foramin (whole)
purpose of interverbal discs
shocker absorption and facilitate movement (as adds a bit of space between each bone)
what’s the structure of the intervertebral discs
- the outer casing is tough = called the annular fibrosis
- softer centre = called the nucleus pulposus
where does the intervertebral discs get its nutrients from
the vertebral bone above
degree of flexion at the spine
90 degrees
