The axillary artery is a continuation of the subclavian artery that begins at the outer border of the first rib . It then courses through the axilla while being bordered by the lateral (superiorly), posterior (posteriorly), medial (inferiorly) cords of the brachial plexus and the ansa pectoralis (anteriorly).
Where is the axillary artery located?
The axillary artery, as a continuation of the subclavian artery, begins at the lateral margin of the first rib and ends normally at the inferior border of the teres major. The axillary artery supplies the walls of the axilla and related regions and continues as the brachial artery, to supply to more distal parts of the upper limb.
What is the function of the axillary artery?
Cutaneous innervation by the radial nerve is provided by the following nerve branches:
- Posterior cutaneous nerve of arm (originates in axilla)
- Inferior lateral cutaneous nerve of arm (originates in arm)
- Posterior cutaneous nerve of forearm (originates in arm)
What is mass of left axilla?

Which ribs are commonly fractured?
The most common ribs fractured are the 7th through 10th ribs. Fractures of the first and second ribs are rare but may be associated with serious damage to the brachial plexus of nerves, the subclavian vessels or associated with head, facial or thoracic aorta injuries.
What does a CT scan of the ribs show?
Doctors use chest CT to: examine abnormalities found on chest x-rays. help diagnose the causes of signs or symptoms of chest disease, such as cough, shortness of breath, chest pain, or fever. detect and evaluate the extent of tumors that arise in the chest, or tumors that have spread there from other parts of the body.
Does broken rib pain get worse before it gets better?
The worst pain is usually the first 1-2 weeks and gets gradually better after that. Healing time also depends on the person.
Are obliques ribs?

Description
The axillary region (also known as the arm pit) is a pyramid-shaped area located between the shoulder girdle and thorax. It serves as a space for neurovascular and lymphatic structures to travel through to reach the upper extremity from the neck.
Clinical Relevance
Thoracic Outlet Syndrome (TOS) results from the compression of nerves and/or vessels at or around the apex of the axilla. The clinical presentation and distribution of TOS is dependent upon the structures compressed. A patient with TOS may complain of ipsilateral upper extremity pain, parasthesia, paresis, discoloration, and/or cold sensitivity.
Anatomy of the Human ribs
The Anatomy of the Human Ribs (costae) are one of the integral parts of the chest wall; they make up the lateral part of our body, its anterior and posterior wall and they entirely build the lateral parts of the chest wall.
Parts of the Human Rib Bones
From the anatomy of the human rib cage, we can tell that the human Ribs bones have several parts: head (caput costae) neck (collum costae) body, corpus costae; and the front part of the rib. The head of the rib includes the articular surface, facies articularis capitis costae.
Properties of the ribs
A rib has a flat body, as you can see from the picture of the anatomy of the human rib cage. The upper edge is round and the lower sharp.
Course
The axillary artery is a continuation of the subclavian artery that begins at the outer border of the first rib .
Branches
The superior (highest) thoracic artery is the first branch of the axillary artery. It is given off proximal to the outer border of the anterior scalene muscle. It forms part of the arterial supply to the pectoral muscles .
Mnemonic
Here is a creative way to remember the branches of the axillary artery!

Overview
A fractured rib occurs when one of the bones in your rib cage breaks or cracks.
Symptoms
The pain associated with a broken rib usually occurs or worsens when you:
Causes
Broken ribs are most commonly caused by direct impacts — such as those from motor vehicle accidents, falls, child abuse or contact sports. Ribs also can be fractured by repetitive trauma from sports like golf and rowing or from severe and prolonged coughing.
Complications
A broken rib can injure blood vessels and internal organs. The risk increases with the number of broken ribs. Complications vary depending on which ribs break. Possible complications include:
