-
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
-
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:
-
sacrum is formed by fusion of:
5 vertebra
-
-
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
