The posterior triangle of the neck is the triangular space on the side of neck behind the sternocleidomastoid muscle. Its apex is directed upwards and backwards towards the mastoid process and base downwards towards the clavicle.
Boundaries:
Anterior is bounded by the posterior border of sternocleoidomastoid muscle.
Posterior is the anterior margin of trapezius muscle.
Inferiorly is bounded by the superior aspect of middle third of the clavicle.
The floor of posterior triangle is muscular and is formed from above downwards by the following muscles:
1. Semispinalis capitis.
2. Splenius capitis.
3. Levator scapulae.
4. Scalenus medius.
5.and on a smal area the Scalenus anterior is also observed. Most of scalenus anterior lies behind the inferior extremity of sternocleidomastoid muscle.
Through the scalene hiatus passes the subclavian artery and trunks of brachial plexus. In front of the scalenus anterior passes the phrenic nerve which is oriented vertically, and the subclavian vein which is oriented horizontally. At this level the subclavian vein recieves the external jugular vein.

Hey ! I think you missed suprascapular artery...
It is the internal jugular with phrenic not external
Niceeeee
Isn't this the lateral region of the neck?

Yes, it is also called, the lateral region of the neck (lateral cervical region).
All things perfect but 1 thing to correct: There's no nerve named greater auricular nerve.......it is great auricular nerve

Maybe both are incorrect, since names must follow a strict convention of root words, prefixes and affixes based on the greek and latin languages. Maybe, look it up yourself to be sure.
its serratus anterior not scalenus anterior maybe

Serratus anterior is a muscle on the side of thorax. Originates on the first 8 ribs at the side of the chest and inserts in the anterior lenght of the medial border of scapula. It is not a muscle of the neck.
