36
MUSCLES in NECK - surrounding THYROID
- STERNOCLEIDOMASTOID (big) - STERNOTHYROID - STERNOHYOID - OMOHYOID
37
NECK COMPARTMENTS are bound by..
PRETRACHEAL FASCIA - separates things and surrounds neck muscles
38
where does the PRETRACHEAL FASCIA go from and to
HYOID BONE to PERICARDIUM (around heart)
39
PRETRACHEAL FASCIA has 2 COMPARTMENTS
MSUCULAR and VISCERAL
40
whats in the VISCERAL COMPARTMENT of the PRETRACHEAL FASCIA

41
what is the name of the CONNECTION / COMMUNICATION of the THORAX with the ROOT of the NECK
SUPERIOR THORACIC APERTURE / THORACIC OUTLET (opening at top of thoracic cavity)
42
what does the SUPERIOR THORACIC APERTURE allow
allows STRUCTURES to PASS TO/FROM NECK and UPPER LIMB (/in or out of thorax) ie Trachea, Oesophagus, Veins, Arteries
43
BOUNDARIES of the SUPERIOR THORACIC APERTURE

49
what are LYMPH VESSELS VITAL for
help TRANSPORT and FILTER EXCESS FLUID (LYMPH) before RETURNING it to VENOUS CIRCULATION
50
