Ligament which limits skull rotation: Alar

Defective portion of vertebra with spondylolisthesis in cervical area: Pedicle

Defective portion of vertebra with spondylolisthesis in lumbar area: Pars interarticularis, Lamina

Common direction of all superior articular facets of vertebrae: Posterior

Structure in contact with posterior surface of dens: Transverse ligament of atlas (part of cruciate)

Most commonly herniated intervertebral disc: L4-5

Nerve injured with fracture of medial humeral epicondyle: Ulnar

Muscle that is the chief flexor and chief extensor at shoulder joint: Deltoid

Muscles innervated by axillary nerve: Deltoid and teres minor

Muscle that initiates abduction of arm: Supraspinatus

Most commonly torn tendon of rotator cuff: Supraspinatus

Two muscles that rotate scapula for full abduction of arm: Trapezius and serratus anterior

Tendon that courses through shoulder joint: Long head of biceps

Chief supinator muscle of hand: Biceps brachii

Primary (major) flexor of the forearm: Brachialis

Orientation of structures located in the cubital fossa-Lateral to Medial: Tendon biceps brachii, brachial a., median n.

Injury to what nerve causes winged scapula: Long thoracic nerve
