2.2 KINESE The Spine

Functions of the Spine

Transmits weight into the pelvis, protects spinal cord, absorbs shock, allows for wide range of motion

Cervical vertebrae

Top seven vertebrae

Thoracic vertebrae

Group of 12 vertebrae after the cervical vertebrae

Lumbar vertebrae

Group of 5 vertebrae after thoracic vertebrae

Sacral vertebrae

Group of 5 vertebrae below the lumbar vertebrae

Coccyx vertebrae

Group of bottom 3-5 vertebrae

Primary/posterior curves

Thoracic and sacral curves

Secondary/anterior curves

Cervical and lumbar curves

Tummy time

How we develop a cervical curve

Psoas strength through sitting up

How we develop a lumbar curve

2 parts of the vertebrae

Body and arch

Annulus Fibrosus

Outer layer of an intervertebral disc

Nucleus Pulposus

Insides of an intervertebral disc

Vertebral arch

A

Vertebral body

B

Pedicle

Lamina

Atlanto occipital joint

Joint connecting the base of the skull to the C1 vertebra, offering flexion and extension in the neck

Atlanto axial joint

Joint connecting the C1 and C2 vertebrae, allows for rotation in the neck

Costovertebral joint

Gliding joint connecting the ribs to the vertebrae

Costotransverse joint

Joint connecting the rib to the transverse process

Costocentral joint

Joint connecting the rib to the vertebral body

Lumbosacral angle

Degree of tilt in the lordotic curve

Superior articulating Facet

Vertebral articular surface that is closer to the body of the vertebra

Inferior articulating facet

Vertebral articular that is further from the body of the vertebra

Sacrum

Bone at the base of the spine made of 5 fused vertebrae, completely fused after 25

Sacral Iliac joint (SI)

Gliding joint that allows the sacrum to nutate and counter nutate

Nutation

The anterior top of the sacrum moves down

Counter Nutation

The anterior top of the sacrum moves up

Passive nutation

A back bend produces ________ in the SI joint.

Passive counter nutation

A forward bend produces _____________ in the SI joint.
