anatomy 2 Flashcards
what can a hoarse voice be caused by
impairment of function of L laryngeal nerve
what is the thoracic inlet bounded by
ribs 1, T1, vertebrae and jugular notch
what is between the sternal angle and T4/T5
transverse thoracic plane
what does the ant mediastinum contain
thymus
what is the thymus
lymphoid organ production T cells in childhood that becomes replaced by adipose tissue after puberty
where does the thoracic duct carry lymph to
left venous angle
where does the azygous vein drain blood from
posterior intercostal veins to SVC
what drains lymph into the R venous angle
R lymphatic duct
what is the swollen start of the thoracic duct in the abdomen called
cisterna chyli
where does the phrenic nerve pass through the diaphragm
with the IVC
what is the ligamentum arteriosum the remnant of
ductus arteriosus
describe the L recurrent laryngeal nerve
Recurrent laryngeal branch of left vagus nerve hooks underneath ligamentum arteriosum and the arch of the aorta, heading back up towards the larynx.
describe the R recurrent laryngeal nerve
The right recurrent laryngeal nerve hooks under the right subclavian artery and doesn’t enter the chest.
what does the ligamentum arteriosum connect
the arch of the aorta and the L pulmonary artery
what are central veins
those large veins close enough to the heart such that the pressure within them is said to approximately reflect the pressure within the right atrium
what arises from teh subclavian artery near its origin
internal thoracic artery
what do the phrenic nerves supply somatic sensory to
pericardium
mediastinal parietal pleura
diaphragmatic parietal pleura and peritoneum
what do the recurrent laryngeal nerves supply
pharynx and larynx
what do CNX contain after they have given off their recurrent laryngeal branches
only parasympathetic fibres
what motor supply does the CNX have
pharynx and larynx
what is the sympathetic outflow
thoracolumbar - T1 to L3
what is the parasympathetic outflow
CN III, VII, IX and X and sacral spinal neves
what is the adrenal gland suplied by
T10 - L1
what is the longest vein in the body
saphenous
