The bones that make up the TMJ joint include; mandible, temporal, and surrounding bones (sphenoid, zygomatic bone and zygomatic arch, maxilla). The joint capsule and ligaments surrounding the articulation allow for slight movement to occur (elevation/depression/ deviation) but also keeps it stabilized. Depression- is the opening of the jaw; anterior rotation of the mandibular condyle of the disk, sliding the disk and condyle forward and downward. Frontal axis Elevation- the closing of the jaw; it involves sliding of the disk and condyle posteriorly and superiorly and occurs around frontal axis in sagittal plane Protrusion/retrusion- is the anterior and posterior movement in the horizontal plane. No rotation takes place but forward and backward motion of all parts of mandible are equal Lateral movement - occurs in horizontal plane around vertical axis. Condyle rotates in the articular fossa while the other condyle glides forward. Movement of the mandible toward the left, requires the left condyle to spin and right condyle to glide forward.

Define how each type of scoliosis presents: R thoracic "C"-curve and R thoracic & L lumbar "S" curve. Define this in terms of convex/concave side of the curve, which side rotation occurs, and which lateral side is shorter
Scoliosis (structural) is the lateral curvature of the spine accompanied with vertebral rotation. Wherever the curve takes place the vertebrae and spinous processes in that area rotate towards the concave portion of the curve. As the rotation occurs and the vertebral bodies shift the spinous processes deviate more and more to the concave side causing the ribs to follow the rotation. This presents with the concave part of the curve having the ribs closer together, and the convex side is more spread apart. Therefore, R thoracic scoliosis will be convex on the right and concave on the left, and the left side will be shorter with vertebral rotation occurring to the left side (concave side). If the patient presents with L lumbar "s" curve is considered to have two scoliotic curves, each curve is described separately. The thoracic curve is convex to the left side and concave to the R, and the lumbar portion is convex to the right, and concave to the left. One portion of the S curve is always bigger (usually the lumbar)- most likely the left side to be shorter.

Explain the relation of the ASIS & Pubic symphysis in neutral, anterior tilt, & posterior tilt.
The ASIS is the point of reference during anterior and posterior pelvic tilt. When the ASIS moves anteriorly the pubic symphysis moves posteriorly. When the ASIS moves posteriorly the pubic symphysis shifts anteriorly. The neutral position is the upright standing position, posture affects this; bad posture in an anterior pelvic tilt increases lumbar extension. Whereas bad posture putting the pelvis into posterior tilt makes the lumbar region kyphotic- flattening the curvature.

A lateral tilt is named by which side? In left single leg stance what happens to the vertebral column and what happens at each of the hip joints?
The tilt is labeled by the unsupported leg, for left single leg stance the right foot is the point of reference. As the right leg leaves the ground to put the person into left single leg stance, the right pelvic side slightly drops and the left side moves up. In relation to the vertebral column; when the pelvis drops or laterally tilts the vertebral column laterally bends in the same direction. (R lateral tilt: Right leg is unsupported, hip drops- Left side moves up- R lateral bend of the vertebral column moves the upper body to the left to compensate for the weight shift).
At the end of a 100-yard dash, please describe:What stabilizing muscles are contracting to allow the abdominals to assist with expiration? Why are they needed?

Explain Hyperventilation and how it can affect a person physiologically. What is a common treatment?
When someone is hyperventilating the person is chest breathing and not using the diaphragm. Knowing that the diaphragm is the main prime mover in proper inspiration, not using it in breathing means that it doesn't descend so the thoracic cavity pressure isn't decreasing enough to allow the lung to fully fill up with air. Chest breathing requires more effort due to the lack of lung volume capacity , the person will need to breathe more rapidly expelling more energy and leads to hyperventilating and fainting.

Cervical Ligaments/Joints where are they located? What is their job/limits? Posterior longitudinal ligament
runs along the vertebral bodies posteriorly, and along the anterior border of the vertebral canal. Purpose is to prevent excessive flexion and to act as a barrier between the intervertebral disks and the spinal cord.
Cervical Ligaments/Joints where are they located? What is their job/limits? Interspinal ligament
runs between successive spinous processes
Cervical Ligaments/Joints where are they located? What is their job/limits? Anterior longitudinal ligament
runs down the vertebral column on anterior surface of bodies. Prevents excessive hyperextension. In the sacrum where it fuses; it is thin superiorly and thick inferiorly.
Cervical Ligaments/Joints where are they located? What is their job/limits? Transverse Ligament-
runs from one side of the atlas to the other and divides the atlas into anterior and posterior compartments Crucial for keeping the dens from displacing posteriorly in the vertebral foramen and damaging the spinal cord
The vertebral column contains fused vertebrae of the:
sacral spine
Accessory ligament that prevents forward rotation of the sacrum

synovial joint anteriorly and syndesmosis posteriorly
Zygomatic arch is made up f what 2 bones?
temporal and zygomatic
AO Joint motion and AA joint movement are almost always combined with movement of ________________________________.
the C3-C7 cervical segments
motion occurs at the lumbosacral joint when the pelvis tilts anteriorly and posteriorly and at what other distal joint?
the hip joints
Ribs 8 through 10 are "false ribs" because: A. they are primarily made of cartilage. B. they articulate with only one vertebral body. C. they do not attach directly to the sternum. D. they have no anterior attachment to the sternum.

vertical direction
Name the suboccipital muscles and describe the action (collectively) of these muscles.
• Rectus capitis posterior major • Rectus capitis posterior minor • Obliquus capitis superior • Obliquus capitis inferior Collectively they all extend the head - they also all stabilize (3 stabilize AO joint and 1 stablizes the AA joint).
1. List and describe the actions of the SCM, Scalenes, and Longus Colli.
• SCM: Sternocleidomastoid does bilateral flexion of the neck and unilaterally does same side lateral flexion of the neck and opposite side rotation. • Scalenes: The scalenes bilaterally assist in neck flexion and unilaterally neck lateral bending • Longus Colli is a prevertebral muscle that flexes the head.
