Origins and Insertions
This location is the insertion for many abdominal muscles and lies midline through the abdominal area.
Linea alba
This is the action of the scalenes as a group when the origin is fixed.
Elevate the ribs during inhalation
These connect the transverse processes to the body of the vertebrae.
Pedicles
This nerve innervates the orbicularis oris.
This is Kayla's favorite food.
Chips and queso
This is the origin and insertion of the rectus abdominis.
O: Pubic crest, pubic symphysis
I: Cartilage of fifth, sixth, and seventh ribs and xiphoid process
This muscle rotates the trunk to the opposite side and laterally side bends to the same side on the anterior side of the body
External Oblique
The temporal bone articulates with this bone superiorly and this bone posteriorly.
Parietal bones, occipital bone
This is another name for the erector spinae muscles.
Paraspinals
These are the actions of the upper trapezius on the vertebral column. (2!)
Rotate the head and neck to the opposite side (unilaterally), laterally flex to the same side (unilaterally) and extend the head and neck (bilaterally)
This is the origin and insertion for the sternocleidomastoid
Sternal head: top of manubrium
Clavicular head: medial 1/3 of clavicle
Insertion: Mastoid process of temporal bone and the lateral portion of superior
nuchal line of occiput
This is the action of the rectus abdominis on the pelvis.
Tilts pelvis posteriorly
These form a gliding joint with three degrees of freedom.
Superior and inferior articular facets
Without this nerve, you can't breathe.
Phrenic nerve
This is the joint between the head and neck (specific name)
Atlantooccipital joint
These are the muscles that can move origin to insertion in this unit. (list 3)
Pec major and serratus anterior (inhalation with scapula fixed)
Rectus Abdominis
External Oblique
Quadratus Lumborum
Scalenes
During exhalation, this action occurs on the diaphragm.
Diaphragm moves upward
Spinous processes of these bones are typically long, thin, and inferiorly oriented.
A push up with hands planted on the floor would be considered this kind of kinetic chain.
Closed chain
Which abdominal muscle compresses the contents of the stomach acting as a girdle?
This muscle originates at the transverse processes of C6-C7 and inserts onto the second rib.
Posterior Scalene
These are the actions of the Multifidi
rotate the vertebral column to the opposite side and extend the vertebral column
Movement between the intervertebral discs is this type while this type of joint is present between the articulating facets.
Gliding joint
These are the muscles of mastication and they are innervated by this nerve.
Lateral Pterygoid, Medial Pterygoid, Masseter, Temporalis
Trigeminal N
Who is Kayla's favorite college quarterback of all time?
