Establishes & maintains the longitudinal axis of the body. Motions occur as a result of the combined motions of the individual veretebrae.
Protects the spinal cord. Shock absorption and transmission (intervertebral disc)
Provides the vertebral column with more strength and resilience (10x more than if a straight rod)
Small, smooth, flat surface on a bone
Anterior, weight bearing part of the vertebrae
Body of the vertebrae
Posterior portion of the vertebrae
The opening for the spinal cord
Where one vertebrae sits on another
Most posterior palpable part of the vertebrae
Between each vertebrae. Absorbs and transmits shock. Maintains flexibility of Vertebral column.
Outside of the intervertebral disk
Inside the intervertebral disk
C1 is also called the what? Also helps give the neck is rotating capability
C2 is referred to as this? Gives the neck a pivot point due to the odontoid process
C7 has a long & prominent spinous process
Where the ribs articulate with the vertebrae
Region of the back that is most injured. Absorbs most of the bodies weight and the weight we carry. Most of the motion occurs at L4-L5.
O= sternum and clavicle I= mastoid process A= bilat: flexes neck Unilat: laterally bends the neck, rotation to opposite side
O= transverse processes of cervical vertebrae
I= ribs 1-2
A= bilat: assists neck flexion
Unilat: lateral bending of the neck
A= trunk flexion; compression of the abdomen
A= bilat: trunk flexion & compression of abdomen
Unilat: lateral flexion, rotation to opposite side
A= bilat: trunk flexion, compression of abdomen
Unilat: lateral flexion, rotation to same side
A= compression of abdomen
Can be static or dynamic, deals with alignment of various body segments
This must be maintained at all times.
During gait; pelvis dips side to side
Lateral pelvic tilt
Decrease the amount of stress placed on ligaments, muscles, and tendons. Improves function. Decreases amount of muscle energy needed to keep the body upright.
