  5. platysma Sternoclei- domastoid

  6. sternocleidomastoid

  7. Infrahyoid muscles thyrohyoid Omohyoid (superior and inferior belly) sternothyroid sternohyoid

  8. stylohyoid digastric (anterior and posterior belly) Suprahyoid muscles mylohyoid

  9. Thyroid gland Parathyroid glands

  10. Hyoid bone(between c3 and c4) Thyroid cartiliage Cricoid cartilage(c6) Crico-thyroid membrane Tracheal cartilage (“c”)

  11. mastoid Hyoid bone(between c3 and c4) Thyroid cartiliage Laryngeal prominence Cricoid cartilage(c6) scapula sternum

  13. vessel

  14. Artery : Common carotid artery( upper border of thyroid cartilige level) internal and external carotid artery Vein: Internal and external jugular vein

  15. artery Internal jugular vein External jugular vein

  16. artery Common carotid artery Subclavian artery (Anterior and middle scalenus) Brachiocephalic artery

  17. upper border of the thyroid cartilage

  18. Internal carotid artery External carotid artery Carotid sinus

  19. vein Internal jugular vein External jugular vein Anterior jugular vein

  20. Analysis Give drug Parenteral nutrition （give nutrition from the recirculating system not digestive system ） Subclavian vein

  21. Fascia and fasical space

  22. Superificial fascia: Skin ,platysma Anterior jugular vein ,External jugular vein Nerve:cervical branch of facial nerve(platysma) cervical nerve Cervical fascia※ ( Investing layer Pretracheal layer Prevertebral layer)

  23. Cervical fascia

  24. pretracheal fascia Infrahyoid m. trachea esophagus thyroid Internal jungular vein Pretracheal layer s.c.m Commoncarotid a. Carotid sheath Vagus n. Buccopharyngeal fascia scalenus Investing layer Prevertebral layer Trapezius

  25. carotid sheath Posterointernal-common and internal carotid artery Anteroexternal-internal jugular vein Between and behind them-vagus nerve anterior posterior

  26. recurrent laryngeal nerve sympathetic trunk Vagus nerve

  27. Fascial space: Pretracheal space Retropharyngeal space Fascial space within Pretracheal laryer

  28. Buccopharyngeal fascia Prevertebe-al laryer Pretracheal space Retropharyn- geal space Fascial space within Prevertebral laryer

  29. Pretracheal space: Thyroid ima artery, Inferior thyroid vein and thymus gland in baby Retropharyngeal space: Fascial space within Pretracheal laryer: cervical tuberculosis become axillary abscess and transfer to mediastinum

  32. s.c.m Anterior triangle Posterior triangle

  33. Anterior belly of digastric m. Hyoid bone Superior belly of omohyoid m.

  34. Submandibular triangle-submandibular gland Submental triangle-submental gland Carotid triangle-carotid sheath

  35. division of the neck Anterior triangle Suprahyoid region: submental triangle submandibular triangle Infrehyoid region: muscular triangle※ carotid triangle※ Posterior triangle

  36. muscular triangle Position Neighborhood Artery Vein Nerve Thyroid gland Superior laryngeal nerve Recurrent laryngeal nerve

  37. SHAPE: H-shaped, isthmus, lateral lobes and pyramidal lobe 50%

  38. POSITION： • Two lateral lobes:at lower part of larynx and anterolateral sides of upper part of trachea • Isthmus: anterior to 2nd--4th tracheal cartilages • Upper pole:mid-point of thyroid cartilage • Lower pole：6th tracheal cartilage

  39. COVERING OF THE THYROID GLAND THYROID SHEATH (false capsule): formed by pretracheal fascia FIBROUS CAPSULE (true capsule): external membrane of thyroid gland

  40. CAPSULE-SHEATH SPACE : between false and true capsules, contains loose connective tissue, blood vessels, nerves and parathyroid gland. SUSPENSORY LIG. OF THYROID GLAND: formed by false capsule, fix the gland at larynx and trachea, and moves up and down when swallowing

  41. Neighborhood： Anterior：superficial fascia(skin,platysma…) investing fascia （s.c.m. infrahyoid muscles ） pretracheal fascia

  42. posteromedial：trachea, esophagus, recurrent laryngeal nerve posterolateral: carotid sheath(common carotid artery, internal jugular vein and vagus nerve) cervical sympathetic trunk behind pretracheal fascia

  43. CLINICAL SIGNIFICANCE tracheal compression-dyspnea（can not breath) esophageal compression-dysphagia（can not swallow) compression of recurrent laryngeal nerve-hoarse voice sympathetic trunk-Horner syndrome

  44. ARTERIES OF THYROID GLAND • Superior thyroid artery: arise from the anterior aspect of the origin of the external carotid a. • Inferior thyroid artery ：branch of thyrocervical trunk • Thyroid ima artery (10%):arise from brachiocephalic trunk of aortic arch

  45. Thyrocervical trunk

  46. VEINS OF THYROID GLAND Superior thyroid vein：accompanied by homonymous artery and joins internal jugular vein. Middle thyroid vein: one, or two, three, or absent; joins internal jugular vein which is thin, preventing bleeding or air embolus when ligation Inferior thyroid vein:joins brachiocephalic veins in front of trachea. Plexus thyroideus impar:formed by anastomosis of branches of two inferior thyroid veins with tributaries of isthmus in front of trachea.

  47. NERVES RELATED TO THYROID GLAND Superior laryngeal nerve Internal branch:distribute in the laryngeal mucous membrane above glottis vocalis , accompanying the superior laryngeal artery External branch:goes inferioanteriorly accompanying the superior thyroid artery, separates with the artery at 1 cm distant to upper pole of lateral lobe to supply cricothyroid muscles and inferior pharyngeal constrictor
