Spinal Bones & Movement
The number of articulating vertebrae in the spinal column.
What is 24?
These are the prime movers in cervical extension, against resistance.
What is the erector spinae?
The trunk is composed of these.
What is thoracic spine, rib cage, and pelvic girdle?
The pull-up or chin-up.
What is closed?
This is the most critical phase that leads to the desired result of an activity, skill, or movement.
What is the preparatory phase?
These can be palpated on the posterior surface of the spine, especially when it's flexed.
What is the spinous process?
From medial to lateral these are the erector spinae muscles.
What is spinalis, longissimus, iliocostalis?
This muscle is responsible for breathing during quiet rest.
What is the diaphragm?
Using the leg extension machine.
What is open?
This phase uses a high amount of eccentric activity to decelerate the limb or body segment.
What is the follow-through phase?
This joint produces the most movement in the cervical region and is considered a trochoidal joint.
What is atlantoaxial joint or C1/C2?
This muscle concentrically contracts to perform extension of the head, right cervical rotation, and right cervical lateral flexion.
What is the right splenius capitis?
This muscle inserts on the costal cartilage of the 8th, 9th, and 10th ribs and the linea alba.
What is the internal oblique?
Alternating prone extension or the Superman exercise.
What is open?
In this phase, there is barely any movement; the body is in a comfortable and balanced position.
What is the stance phase?
Nearly all the movement of the spinal column occurs within these two regions of the spine.
What is the cervical and lumbar spine?
This muscle contracts to perform cervical flexion, left cervical rotation, and right cervical lateral flexion.
What is the right sternocleidomastoid?
This muscle inserts at the anerior half of the crest of the ilium, inguinal ligament, crest of pubis, and fascia of rectur abdominis.
What is the external oblique?
The bench press or chest press.
What is open?
Some sports skills have this phase, where the body regains balance and positioning to be ready for the next sport demand.
What is the recovery phase?
This is described as a return movement from lateral flexion to a neutral position.
What is reduction?
This muscle inserts on the transerse processes of the first 3 cervical vetebrae .
What is the splenius cervicis?
During the up portion of the sit-up with rotation to the left, these muscles are used the most.
What is the left internal oblique and right external oblique?
Fingertip push-ups.
What is closed?
During a baseball pitch, this phase includes the arm going forward into shoulder girdle protraction, shoulder joint internal rotation and diagonal adduction until the release of the ball.
What is movement phase?
