The bodies of the thoracic vertebra become progressively _______ as we move distally
massive!
T/F. Each of the thoracic vertebra articulate with a pair of ribs
True
False
true
The two facets of the rib articulate with the bodies of two vertebra to form the
Costo-Vertebral Joint
The tubercle of the rib articulates with the TP to form:
type of joint:
type of movement here:
Costo-Transverse Joint
synovial
permits movement of ribs during respiration
movements assoc c/ thoracic spine:
why is there only a little movement of the thoracic spine?
Forward flexion, Extension (very little), Lateral flexion, Rotation
because of the attachment of the ribs and partly because of the arrangements of the Articular Facets
regarding the lumbar, superior facets face:
inferior facets face:
sup
: inward
inf
: outward
sacrum is formed by fusion of:
5 vertebra
sacrum curves:
backwards
Dorsal surface has 2 Articular Facets which articulate with:
with the annominate on each side to form the pelvis
Posterior rami exit via:
dorsal sacral foramina
Anterior Rami exit via:
Anterior sacral Foramina
The Vertebral Canal ends at the:
sacral foramen
(shaped like an upside down V)
regarding the pelvis, There is a curved, irregular articular surface of the sacrum that articulates with:
the annominate on each side to form the pelvis
massive pad of Fibrocartilage that is firmly attached to the vertebra above and below all the way around the circumference:
Intervertebral Discs
T/F:The IVD is solid enough to transmit and support the weight of the body and flexible enough to permit movement between the vertebra’s.
the IVD consists of an outer ring of tough fibrocartilage called:
Anulus Fibrosis
the IVD has a soft center that is of gelatinous consistency called
Nucleus Pulposis
Intervertebral foramen: lateral and posterior portions of the disc makes up part of the IVF through which:
Spinal Nerve emerges
interspinous ligament runs from:
the lower edge of one spinous process to the upper edge of the next one
ligament that serves as a
midline attachment for some important muscles
supraspinous ligament
supraspinatus ligament merges with what ligament and runs the whole length of the spinal column connecting the spinous processes?
interspinous ligament
The Supraspinous ligament in the cervical spine is referred to as the:
Nuchal ligament
purpose of the supraspinous ligament?
help to “reduce flexion” of the spine
structures that limit flexion of the vertebral column is a series of short ligaments that hold the lamina together:
ligamentum flavum
ligamentum flavum lies on the front of the:
lamina
ligament that is made up of yellowish fibrous tissue hence its name which translates to “yellowish ligament”:
Ligamentum flavum
2 ligaments that hold the vertebral bodies together:
which is stronger:
Anterior Longitudinal Ligament
Posterior Longitudinal Ligament
ALL is stronger
what is the difference btwn Anterior Longitudinal Ligament and the Posterior Longitudinal Ligament?
ALL:
limits Ext of spine
covers front and sides of vertebral bodies
thick and strong
attached to upper and lower edges of each vertebral body
PLL:
limits flexion of spine
runs the back of vertebral bodies
its narrow longitudinally where it overlies each body & is widened out where it covers each disc
Each vertebra is attached to its neighbor by:
Intervertebraldiscs and ligaments
and posterior joints
Each Posterior Joint is surrounded by:
by a Capsular Ligament that is loose enough to accommodate the movement that occurs between a set of vertebra
The Capsular Ligament has no great strength but the articular processes themselves are strong because:
because the upper ones face forward and the lower ones face backward
the articular processes prevents slippage of the vertebra above forward relative to the one below
The _______ permits movement and the ________ prevent slippage of the vertebra
Capsular Ligament
Articular Processes
