types of joints, motions of neck and trunk, prime movers of neck and trunk,...

Description

Kinesiology Notes Neck/Trunk Unit Important Concepts to Remember: 

Joint Motions of the Neck o Flexion, extension, hyperextension o Lateral bending o Rotation



Joint Motions of the Trunk o Flexion, extension, hyperextension o Lateral bending o Rotation



Importance of the Facet Joint



Movements in specific vertebral areas o Lumbar: flexion and extension o Thoracic: rotation and lateral bending o Cervical: all motions



The layers of trunk muscles o Superficial o Intermediate o Deep



5 Prime Movers of the Neck: o Sternocleidomastoid * o Splenius Captius* o Splenius Cervicis* o Scalenes * o Erector spinae



9 Prime Movers of the Trunk o Rectus Abdominis* o External Oblique o Internal Oblique o Transverse Abdominis o Erector Spinae o Transversospinalis o Interspinalis o Intertransversarii

o Quadratus Lumborum *5 Muscles you need to know OI information! Neck and Trunk: Study Guide Content 1. Know the vertebra parts and the specific vertebrae joint movements

2. Know actions of trunk/neck.  Flexion, extension, hyperextension  Lateral bending  Rotation 3. Know the O, I, A information for these muscles:  Sternocleidomastoid o O: sternum and clavicle o I: mastoid process o A: bilaterally – flexes neck, unilaterally – laterally bends the neck, rotation to the opposite side  Scalene o O: transverse processes of cervical vertebrae o I: ribs one and two o A: bilaterally – assists neck flexion, unilaterally – lateral bending of the neck  Splenius capitis o O: lower half of nuchal ligament, spinous processes C7-T3 o I: lateral occipital bone, mastoid processes o A: bilaterally – extend head, unilaterally – rotate and laterally flex to the same side  Splenius cervicis o O: spinous processes T3-T6 o I: transverse processes C1-C3 o A: bilaterally – extend head, unilaterally – rotate and laterally flex to the same side  Rectus abdominis o O: pubis o I: costal cartilage of ribs 5-7

o A: trunk flexion, compression of abdomen 4. Know the summary of muscle actions for both neck and trunk. NECK Action Flexion Extension Lateral bending Rotation (same side) Rotation (opposite side) TRUNK Action Flexion Extension Lateral bending

Rotation (same side) Rotation (opposite side) Compression of abdomen
