Where is axilla located?
The axilla is an anatomical region under the shoulder joint where the arm connects to the shoulder. It contains a variety of neurovascular structures, including the axillary artery, axillary vein, brachial plexus, and lymph nodes.
What is axillary position?
The axilla (also, armpit, underarm or oxter) is the area on the human body directly under the joint where the arm connects to the shoulder.
Where is the axillary lymph node located?
The body has about 20 to 40 bean-shaped axillary lymph nodes located in the underarm area. These lymph nodes are responsible for draining lymph – a clear or white fluid made up of white blood cells – from the breasts and surrounding areas, including the neck, the upper arms, and the underarm area.
Is the axillary posterior or anterior?
The axillary apex is the interval between the superior border of the scapula, the posterior border of the clavicle, and the external border of the first rib. The pectoralis major and the latissimus dorsi form the major anterior and posterior folds, respectively, of the axilla.
What is the muscle under the armpit called?
Pectoralis major: This large fan-shaped muscle stretches from the armpit up to the collarbone and down across the lower chest region. It connects to the sternum (breastbone).
What is the difference between sentinel and axillary lymph nodes?
Axillary dissection removes more nodes and disrupts more of the normal tissue in the underarm area than a sentinel node biopsy. So, it’s more likely to affect arm function and more likely to cause lymphedema. For this reason, sentinel node biopsy is the preferred method to check the axillary lymph nodes.
Can axillary lymph nodes be felt?
Lymph nodes can only be felt in the areas listed: head and neck. arms. axilla (armpits)
Is the axillary vein in the axillary sheath?
The structures traversing the apex of the axilla are grouped into a neurovascular bundle. However, the axillary vein (as well as lymphatics and lymph nodes) is outside the axillary sheath, providing room for it to expand. …
