branches of the costocervical trunk:
superior intercostal and deep cervical
part 3 of the subclavian artery includes:
dorsal scapular artery
parts of the subclavian artery are in relation to:
the anterior scalene muscle
anterior jugular vein descends neck and drains into:
external jugular or subclavian veins
right and left jugular veins unite in midline to form:
jugular venous arch
internal jugular vein unties with:
subclavian vein to form brachiocephalic vein (venous angle)
thoracic duct terminates in junction between:
left IJV and left subclavian veins
near junction, the thoracic duct is joined by:
left jugular trunk, left subclavian trunk, and left bronchomediastinal trunk
left jugular trunk drains:
left side of head and neck
left subclavian trunk drains:
left upper limb
left bronchomediastinal trunk drains:
left half of thoracic structures
5 groups of superficial LNs form a ring around the head:
occipital, mastoid, pre-auricular and parotid, submandibular, and submental nodes
superficial cervical lymph nodes are found along:
EJV on superficial surface of SCM
superficial cervical LNs primarily drain:
posterior and posterolateral regions of the scalp through occipital and mastoid LNs
deep cervical LNs are found along the:
IJV
deep cervical LNs are divided into upper and lower groups by the:
intermediate tendon of omohyoid
jugulodigastric deep cervical LNs:
most superior, located where posterior belly of digastric crosses IJV; receives lymphatic drainage from tonsils and tonsillar region
jugulo-omohyoid deep cervical nodes:
located just inferior to intermediate of omohyoid; receives lymphatic drainage from the tongue
nerves in the root of the neck:
phrenic, vagus, and sympathetic trunks
vagus nerve branches in the neck:
pharyngeal, superior laryngeal, right recurrent laryngeal, left recurrent laryngeal, and cervical cardiac branches
postsynaptic neurons from ganglia send fibers to the cervical spinal nerves via:
gray rami communicantes
3 layers of cervical viscera from superficial to deep:
endocrine, respiratory, and alimentary levels
endocrine layer of cervical viscera consists of:
thyroid and parathyroid
respiratory layer of cervical viscera consists of:
larynx and trachea
alimentary layer of cervical viscera consists of:
pharynx and esophagus
thyroid gland lies deep to:
sternohyoid and sternothyroid muscles
accessory thyroid tissue may appear:
anywhere along the course of the thyroid gland as it relocates during development
thyroid gland receives arterial supply from:
superior thyroid and inferior thyroid arteries
superior thyroid artery supplies the:
anterosuperior aspect of the thyroid
inferior thyroid artery supplies the:
posterior aspect of the thyroid including inferior pole
thyroid ima artery
a small, unpaired thyroid ima artery arises from the brachiocephalic trunk in approximately 10% of people
superior thyroid veins drain:
superior poles
middle thyroid veins drain:
middle of lobes
inferior thyroid veins drain:
inferior poles
superior and middle thyroid veins drain into:
IJV
inferior thyroid vein drains into:
brachiocephalic vein
thyroid gland lymphatics drain initially into:
prelaryngeal, pretracheal, and paratracheal LNs
prelaryngeal LNs drain into:
superior deep cervical LNs
pretracheal and paratracheal LNs drain to:
inferior deep cervical LNs
injury to recurrent laryngeal nerve causes:
hoarseness
arterial supply to parathyroid glands is mostly from:
inferior thyroid glands
