|
|
Inferior triangle of the neck: roof and floor
|
roof: investing cervical fasciae
floor: vertebral column with anterior prevertebral muscles |

thyroid gland, larynx, trachea, espohagus
|
|
neck fascia layers: names and organizations
|
superficial layer, investing layer, infrahyoid layer (muscles), carotid sheath (common carotid, internal jugular)
visceral fascia (organs) - pretrachial- thyroids/parathyroids, anterior - buccopharyngeal- posterior of pharynx prevertebral fascia |
|
alar fascia
|
makes T shape, precursor to prevertebral
|
|
fascia danger zone

|
facial expression muscle: innervation and derivation
|
derived from second pharyngeal arch, innervated by facial nerve (C7)
|
|
Inferior triangle of the neck: superficial veins
|
anterior jugular veins, exterior jugular veins, arch of jugular vein
|
|
Inferior triangle of the neck: superficial nerves
|
greater auricular, transverse cervical, supraclavicular
motor: cervical branch of facial nerve |
|
infrahyoid muscles
|
innervated by C1-C3 of ventral rami (ansa cervacalis), used in vocalization and swallowing
thyrohyoid only innervated by C1 |
|
thyroid glands
|
thyroid - has right and left lobe, isthmus in middle.
Cricothyroid cartilage above it, middle of that is pyramidal lobe |
|
parathyroid glands
|
posterior to thyroid glands, 2 pairs - inferior and superior. superior and inf thyroid artery runs near them
|
|
Thyroid gland covering
|
Internal layer is thin and divides gland into lobules, connected to external gland which is tough, between is space with parathyroid glands
|
|
Thyroid gland blood supply
|
External carotid - superior thryoid artery
Subclavian artery - Thyrocervical trunk - inferior thyroid artery be careful for thyroid ima artery when getting to trachea |
|
Thyroid gland innervations:
|
vagus nerve (with carotid art and internal jugular vein), superior laryngeal nerve - external (lateral) and internal (medial), right recurrent laryngeal nerve (usual left), left recurrent laryngeal nerve (usual right)
|
|
Thyroid gland drainage
|
superior and middle thyroid vein - internal jugular.
inferior thyroid vein - left brachiocephalic vein Thyroid venous plexus |
|
Thyroid gland lymph nodes organization
|
superficial and deep rings connected by deep cervical trunk
|
|
thryoid gland lymph nodes
|
superior deep cervical, inferior deep cervical, prelaryngeal, pretracheal, paratracheal
|
|
thyroid gland development
|
starts at basal midline of tongue and migrates to tracheal cartilage
|
|
parathyroid gland development
|
superior pair from fourth pharyngeal arch, inferior pair from the third pharyngeal arch
ultimobranchial body (has parafollucular cells that secrete calcitonin) is from fifth pharyngeal arch |
|
Cysts and fistulas in neck
|
Medial cysts and fistulas are remnants of thyroglossal duct, failure to regress - cyst (neck mass)
lateral cysts/fistulas remnants of ductal portions of cervical sinus, from tissue migration during embryonic development |
