5. apical group (infraclavicular) – surrounds subclavian a. receives lymph vessels arising from the central nodes efferent vessels arising from apical axillary lymph nodes join to form subclavian trunk Right subclavian trunk – opens into the right brachiocephalic v. (angulus venosus) Left subclavian trunk – terminates into the thoracic duct which opens into the left brachiocephalic v. (angulus venosus) LYMPH DRAINAGE OF LOWER LIMB AND ADJOINING PART OF TRUNK the lymph from the lower limb and lower part of trunk is drained into the inguinal lymph nodes INGUINAL LYMPH NODES are divided into the superficial and deep groups SUPERFICIAL INGUINAL LYMPH NODES Receive lymph from: •free lower limb – superficial structures (skin, subcutaneous tissue) •gluteal region • lateral abdominal wall • anterior abdominal wall • external genital organas • uterus! • lower part of the anal canal The lymph from the superficial lymph nodes is drained into the external iliac lymph nodes and into the deep inguinal lymph nodes DEEP INGUINAL LYMPH NODES are placed around femoral vessels in the femoral triangle near the inguinal ligament receive • deep lymph vessels of lower limb (accompanying blood vessels) efferent lymph vessels arising from the deep lymph nodes terminate in the external iliac lymph nodes LYMPH VESSELS OF FREE LOWER LIMB Deep – accompany femoral a. and its branches popliteal lymph nodes are placed around popliteal a. Superficial lymph vessels – accompany saphenous veins medial group – ascends along the great saphenous v. (to terminate into the inferior superficial inguinal nodes) lateral group – ascends along m the small saphenous v. (to terminate partly into the popliteal, partly into the inferior superficial inguinal nodes) 85
LYMPH ORGANS THYMUS lymphoid organ and endocrine gland main function: - differentiation of lymphocytes into the different classes - production of various factors and hormones which regulate lymphocytes production, differentiation and activities within the thymus, peripheral lymphoid tissue and elsewhere located in the anterior mediastinum extends into the neck may reach lower part of thyroid gland (in children) relations: anteriorly – sternum and costal cartilages - infrahyoid muscles posteriorly – heart in pericardium - brachicephalic veins and sup. v. cava - aortic arch and its branches - trachea laterally – pleurae and lungs varies in size with age at birth: 10 – 15 gm grows up to the puberty: 30 – 40 gm progressively diminishes – atrophy, replacement by fat mid-adult life: 10 gm childhood pinkish-grey in colour lobulated right and left lobes connected by fibroareolar tissue Structure: fibrous capsule septa → lobules lobule – cortex, medulla (fewer lymphocytes than the cortex) Blood supply: arteries Thymic branches of inf. thyroid a. and int. thoracic a. Veins – drained into the inf. thyroid, brachiocephalic and int. thoracic veins Nerve supply: sympathetic nerves – cervicothoracic ganglion parasympathetic fibres (vagus n.) 86
