- The lymphatics of the upper limb are classified into two main groups:
𝑰. 𝑺𝒖𝒑𝒆𝒓𝒇𝒊𝒄𝒊𝒂𝒍 𝒍𝒚𝒎𝒑𝒉𝒂𝒕𝒊𝒄𝒔 ⇈
1. Lymphatics from the middle, ring, and little fingers and from the medial part of
the hand follow the basilic vein.
- They terminate into the supra-trochlear lymph nodes, then into the lateral (brachial)
lymph nodes, and finally into the apical group of the axillary lymph nodes.
2. Lymphatics from the thumb, index, and lateral part of the hand follow the cephalic
vein.
- They pass through the “deltopectoral groove” and pierce the “clavipectoral fascia” to
terminate into the apical group of the axillary lymph nodes (see axillary lymph nodes).
𝑰𝑰. 𝑫𝒆𝒆𝒑 𝒍𝒚𝒎𝒑𝒉𝒂𝒕𝒊𝒄𝒔 ⇊
- They are few in number.
- They ascend along the main blood vessels of the upper limb to terminate into the
lateral (brachial) group of axillary lymph nodes.
