What does Thoracoacromial artery supply?

Supply. Through its four main branches, the thoracoacromial artery contributes arterial supply to the pectoralis major and minor muscles, the anterior part of the deltoid muscle, and dermal sensation overlying the clavipectoral fascia ².

Similarly, you may ask, what does the Thoracodorsal artery supply?

The thoracodorsal artery supplies predominantly the latissimus dorsi muscle but also gives branches to the serratus anterior muscle, the axillary skin, the subscapular and teres major muscles.

Also, what are the branches of axillary artery? axillary artery: a continuum of the subclavian artery in the axillary area that branches into highest thoracic, lateral thoracic, anterior humeral circumflex, posterior humeral circumflex, thoracoacromial, and subscapularis.

Additionally, what does lateral thoracic artery supply?

In human anatomy, the lateral thoracic artery (or external mammary artery) is a blood vessel that supplies oxygenated blood to the lateral structures of the thorax and breast.

What is the Clavipectoral fascia?

The clavipectoral fascia is a sheet of loose connective tissue which is the deep layer of fascia in the pectoral region. It acts to suspend the floor of the axilla.

What does Subscapular artery supply?

Subscapular artery. The subscapular artery is the largest branch of the axillary artery. It distributes blood to the muscles of the scapular and shoulder regions. The thoracodorsal artery supplies the latissimus dorsi, the broadest muscle of the back.

How deep is the brachial artery?

The deep brachial artery is deep within the arm, and runs parallel to the humerus. It originates just below the shoulder at the axillary artery, and branches into two smaller arteries, the radial and ulnar arteries, at the elbow.

What are the two major branches off of the brachial artery?

The brachial artery gives rise to the following branches:

• Profunda brachii artery (deep brachial artery)
• Superior ulnar collateral artery.
• Inferior ulnar collateral artery.
• Radial artery (a terminal branch)
• Ulnar artery (a terminal branch)
• Nutrient branches to the humerus.

How many internal thoracic arteries are there?

two

What does the anterior circumflex humeral artery supply?

The anterior circumflex humeral artery provides part of the blood supply to the glenohumeral joint, teres major and minor, and deltoid muscles. The ascending branch provides supply to the head of the humerus ¹.

What goes through the triangular space?

The triangular space is an anatomic interval medial to the quadrangular space. Its borders are formed by the long head of the triceps laterally, the teres minor superiorly, and the teres major inferiorly. The circumflex scapular artery, a branch of the scapular artery, passes through the triangular space.

Where does the Thoracodorsal nerve come from?

The thoracodorsal nerve is a nerve present in humans and other animals, also known as the middle subscapular nerve or the long subscapular nerve. It supplies the latissimus dorsi muscle. It arises from the brachial plexus. It derives its fibers from the sixth, seventh, and eighth cervical nerves.

What muscles does the circumflex scapular artery supply?

The subscapular artery has two main branches, the circumflex scapular artery and thoracodorsal artery . The thoracodorsal artery supplies the latissimus dorsi muscle. The circumflex scapular artery passes through the triangular space and participates in the collateral circulation of the scapula ( see Laboratory Three).

What does the internal thoracic artery supply?

The internal thoracic artery supplies the anterior body wall from clavicle to umbilicus including the sternum and the breasts. In addition, via the pericardiophrenic artery it supplies the mediastinum, thymus, phrenic nerves and pericardium.

Where does the lateral thoracic artery branch from?

The lateral thoracic artery originates from the medial surface of the axillary artery, posterior to the distal part of pectoralis minor. It courses inferomedially along the inferior border of pectoralis minor to the anterior surface of serratus anterior.

What does superior thoracic artery supply?

Superior thoracic artery. Running forward and medially along the upper border of the pectoralis minor, the superior thoracic artery passes between it and the pectoralis major to the side of the chest. It supplies branches to the first and second intercostal spaces as well as to the superior portion of serratus anterior

What muscles does the axillary artery supply?

The second part of the axillary artery has two branches: thoracoacromial artery: runs over pectoralis minor to pierce the clavipectoral fascia and supply the clavicle, deltoid, acromion and pectoralis muscles via its four terminal branches.

What are the branches of the subclavian artery?

The branches of the subclavian artery are the:

• Vertebral artery.
• Internal thoracic artery.
• Thyrocervical trunk.
• Costocervical trunk.
• Dorsal scapular artery.

Where does the Suprascapular artery come from?

The suprascapular artery begins at the thyrocervical trunk (a branch of the subclavian artery) and goes across the phrenic nerve and a deep muscle located on each side of the neck called the scalenus anterior.

Where does the internal thoracic vein drain?

In human anatomy, the internal thoracic vein (previously known as the internal mammary vein) is a vessel that drains the chest wall and breasts. Bilaterally, it arises from the superior epigastric vein, accompanies the internal thoracic artery along its course and terminates in the brachiocephalic vein.

Where does the superior epigastric artery come from?

Origin and course. The superior epigastric artery originates at the level of the sixth or seventh costal cartilage. It descends to the anterior abdominal wall, crossing the diaphragm in the interval between the sternal and the costal parts of the muscle.

What nerve runs with lateral thoracic artery?

The long thoracic nerve (respiratory nerve of Bell) originates from roots C5, C6, and C7 of the brachial plexus and provides motor stimulation to the serratus anterior muscle. It usually can be found adjacent to the lateral thoracic artery's origin and runs along the serratus anterior.
