With reference to linear motions of the scapula, upward movement of the scapula is referred to as ___________ and downward movement of the scapula is referred to as ____________
elevation; depression
______________ is described as the scapula moving away from the vertebral column in a linear fashion.
Protraction
______________ is described as an angular motion where the glenoid fossa of the scapula tilts downward while the inferior angle moves toward the vertebral column.
Downward rotation
Name the scapular bony landmark that is formed by the junction of the axillary border and the vertebral border.
inferior angle
Name the scapular bony landmark that is found on the superior medial aspect, which provides attachment to the levator scapulae.
superior angle
With regard to scapular bony landmarks, the _____________ is found more medially, while the ___________ is found on the lateral aspect of the scapula.
vertebral border; glenoid fossa
Name the prominent bump on the inferior, posterior aspect of the occipital bone.
external occipital protuberance
Name the region of the spine through which the ligamentum nuchae runs.
cervical
