Name the attachments for the Trapezius. | Origin (Occipital protuberane, Nuchal ligament, and SP of C7 and thoracic vertebrae) Insertion (clavicle, acromion, and spine of scapula) |
Name the attachments of the Latissimus Dorsi. | Origin (sacrum to T7, thoracolumbar fascia, iliac crest, and ribs 10-12) Insertion (Intertubercular groove of humerus) |
Name the attachments of the levator scapulae. | Origin (TP of C1-C4) Insertion (upper medial scapula) |
Name the attachments of the splenius capitis. | Origin (Nuchal ligament, SP of C7-T4) Insertion (Mastoid process, and occipital protuberance) |
Name the attachments of the splenius cervicis. | Origin (SP of T3-T6) Insertion (TP of C2-C3) |
Name the Erector Spinae muscles | Iliocostalis, Longissimus, and Spinalis |
Name the attachments of the Iliocostalis. | Origin (sacrum, iliac crest, and SP of lumbar and T11-T12) Insertion (Ribs 1-12, and TP of C4-C7) |
Name the attachments of the Longissimus. | Origin (thoracolumbar fascia, TP of lumbar, TP of T1-T5, and AP of C3-C7) Insertion (Mastoid process) |
Name the attachments of the Spinalis. | Origin (SP of L2-T11, Nuchal ligament, and SP of C7) Insertion (SP of T1-T8, and SP of C2) |
Name the attachments of the semispinalis capitis. | Origin (TP of C7-T6) Insertion (between the superior and inferior nuchal lines of the occipital bone) |
Name the attachments of the Multifidus. | Origin (sacrum, lumbar, thoracic, and C7-C4 vertebrae) Insertion (SP of lumbar thoracic, cervical vertebrae to C2) |
Name the attachments of the Rhomboid Major. | Origin (SP of T2-T5) Insertion (medial scapula) |
Name the attachments of the Rhomboid Minor. | Origin (nuchal ligament, and SP of C7-T1) Insertion (medial scapula) |
Identify the border muscles in the suboccipital triangle. | Rectus capitis posterior major, Rectus capitis posterior minor, Obliquus capitis superior, and Obliquus capitis inferior. |
Describe the contents of the suboccipital triangle. | Vertebral Artery and Suboccipital nerve. |
Describe the cervical vertebrae. | The cervical vertebrae are the smallest and have transverse foramen. The Altas C1 - lacks a vertebral body and forms the atlanto occipital joint. The Axis C2- has the "dens" which projects superiorly and articulates with the atlas. |
Describe the thoracic vertebrae. | Medium sized with transverse processes that attach to the ribs |
Describe the lumbar vertebrae. | Largest bodies, these vertebrae hold the most weight. |
Identify the nerve and artery found in the rhomboids. | The dorsal scapular nerve from C5 root of the brachial plexus and the deep branch of the transverse cervical artery from the posterior triangle of the neck. |
Identify the nerve and artery found in the trapezius. | The transverse cervical nerve(Cranial nerve XI), and the superficial branch of the transverse cervical artery from the posterior triangle of the neck. |
