Triangle of occultation

Trapezius, rhomboid, latissimus dorsi

1

Anterior longitudinal ligament

Anterior to bodies of vertebra

2

Posterior longitudinal ligament

Posterior aspect of vertebral column

3

Ligamenta flava

Join laminae of adjacent vertebra

4

Inter spinous ligament

Interior to spinous processes

5

Supra spinous ligament

On top of spinous processes

6

Nuchal ligament

Nuchal line to c7
Attaches to supra spinous ligament

7

Tectorial membrane

Continuation of posterior longitudinal ligament through foramen magnum

8

Suboccipital nerve

Posterior ramus of c1
Innervates sub occipital triangle

9

Vertebral artery

In sub occipital triangle

10

Greater occipital nerve

Posterior ramus of c2
Emerges inferior to obliqus capitis inferior and ascends to posterior scalp
Distribution of skin over neck and occipital bone

11

Spinal accessory nerve

Cranial nerve XI
SCM, lateral cervical region
Runs on the levator
Trapezius

12

Roots of brachial plexus

C5-c8 and t1
Between anterior and middle scalene

13

Lesser occipital nerve

C2
Supplies skin of the neck and scalp posterosuperior to the auricle

14

Great auricular nerve

C2 and c3
Ascending vertically across sternocleidomastoid onto the parotid gland
Divides and supplies posterior aspect of the auricle and the area of skin overlying the angle of the mandible to the mastoid process

15

Transverse cervical nerve

C2 and c3
Supplying the skin covering the anterior cervical region
Curves around middle of posterior border of SCM and passes anteriorly and horizontally across it, deep to the EJV and platysma

16

Supra clavicular nerves

C3 and c4
Common trunk under cover of SCM and send small branches to skin of the neck and cross the clavicle to supply skin over the shoulder

17

Phrenic nerves

Originate chiefly from the 4th cervical nerves but receive contributions from c3 and c5
Above anterior scalene

18

External jugular vein

Angle of mandible crosses SCM obliquely, deep to platysma, pierces investing layer of deep cervical fascia
Inferior part of lateral cervical region
Terminates in subclavian vein

19

Subclavian vein

Drains upper limb
Inferior part of lateral cervical region
anterior to anterior scalene and phrenic nerve

20

Transverse cervical artery

Originates from thyrocervical trunk, branch of subclavian artery
Divides into superficial cervical and dorsal scapular
Superficial and lateral to phrenic and anterior scalene muscles
Crosses trunks of brachial plexus
Deep to trapezius


21

Dorsal scapular artery

anterior to insertions of rhomboid muscles, accompanying dorsal scapular nerve

22

Supra scapular artery

Arises from cervical dorsal trunk or directly from subclavian
Infero laterally across anterior scalene and phrenic
Crosses subclavian artery and cords of brachial plexus
Passes posterior to clavicle to supply muscles on the posterior aspect of the scapula

23

Occipital artery

Branch of external carotid artery crosses apex of lateral cervical region ascending to supply posterior half of the scalp

24

Third part of subclavian artery

supplies blood to upper limb
Begins approximately a fingers breadth superior to the clavicle, opposite the lateral border of the anterior scalene muscle
In contact with first rib as passes below anterior scalene
