The neck can be divided into
anterior and posterior triangle
Boundaries of anterior triangle superiorly
Inferior border of mandible
Boundaries of anterior triangle posteriorly
Anterior border of sternocleidomastoid
Boundaries of anterior triangle anteriorly
Middle of the neck
Anterior triangle contents
Suprahyoid and infrahyoid muscles
Common carotid artery
Internal jugular vein
CN VII, IX, X, XI and XII
Boundaries of posterior triangle anteriorly
Posterior border of sternocleidomastoid
Boundaries of posterior triangle posteriorly
Anterior border of trapezius
Boundaries of posterior triangle inferiorly
Midle 1/3rd of clavicle
Posterior triangle contents
Omohyoid muscle Splenius capitis, levator scapulae and scalene muscles External jugular vein Subclavian artery CN XI Cervical plexus
Location of thyroid gland
Visceral compartment of the front of the neck
Where does the thyroid gland lie in relation to the larynx
Anterior
Anatomical parts of thyroid gland
Right and left lobes
Isthmus

Endocrine
Function of parathyroid glands
Endocrine glands
Produce parathyroid hormones
Location of the parathyroid glands
Variable, on the back of the thyroid glands
Compartments of the neck in horizontal section
Vertebral
Vascular
Visceral
Musculofascial collar
Neurovascular structures of the neck
Carotid sheath
Carotid arteries
Internal jugular vein
Vagus nerve

Common carotid artery
External and internal carotid arteries
Internal and external jugular veins
Where does the common carotid artery branch from on the right side?
Brachiocephalic artery
Where does the common carotid artery branch from on the left side?
Directly from arch of the aorta
Cervical plexus is formed by
ventral rami of C1-C5
