lymphatics Flashcards
what are the tributaries of thoracic duct in abdomen?
2 lumbar, 1 gastrointestinal, 2 intercostal,
what vertebral level is thoracic duct, what structure often marks it and how does it enter thorax from abdomen?
L2, cisterna chyli in 20% of individuals, through aortic hiatus.
where does the thoracic duct end?
left jugulosubclavian junction
what are the tributaries of thoracic duct in thorax?
mediastinal-from upper liver, diaphragm, heart, oesophagus,
5/6 upper intercostal trunks
what are the tributaries of thoracic duct in the neck?
left subclavian trunk from left upper limb,
left jugular from left head and neck,
left bronchomediastinal from upper left thorax and heart.
true/false, lymph nodes are spread through the right lymphatic duct and thoracic duct
false. they are free from nodes.
what lymph groups drain breast?
mostly axillary, rest-infraclavicular, parasternal, some intercostal nodes, also abdominal.
where does the lymph drainage of breast go when normal ones are blocked?
inferior deep cervical nodes/ contralateral breast.
what do the superficial and deep inguinal nodes drain and where do they drain their efferent to?
the proximal superficial drains skin, external genitalia except testes, bit of uterus, anal region. the distal one drains lower limb. the deep nodes drain lower limb, perineum, anterior abdominal wall and lymph from superficial nodes. they all drain into external and common iliac and aortic nodes, which then from aortic forms the two lumbar trunks.
true/false, the distal superficial inguinal nodes are along the femoral vein.
false, they’re along great saphenous vein. femoral is for deep inguinal.
where does the lymph from testes drain into?
both lumbar and preaortic
what do the tributaries of lumbar lymph trunks drain?
urogenital organs, posterior body wall, lower limbs.
where does the lymph from lungs drain into?
bronchomediastinal trunk.
