Quick Review of upper limbs Veins:
1. Radial Vein: It runs along the radial side of the forearm and joins with the ulnar vein to form the brachial vein.
2. Cephalic Vein: It is located on the lateral aspect of the upper limb and runs in the deltopectoral groove. It is commonly used for venous access.
3. Vein of the Forearm: This refers to the superficial veins in the forearm, including the basilic vein and the median antebrachial vein. These veins contribute to the formation of the brachial vein.
4. Anterior Ulnar Recurrent Vein: It is a small vein that connects the basilic vein with the ulnar vein.
5. Median Cubital Vein: It is a superficial vein that connects the cephalic vein and the basilic vein in the cubital fossa.
6. Deep Veins: There are deep veins that accompany the arteries of the upper limb, such as the deep brachial vein that runs with the brachial artery.
Quick Review of upper limbs Arteries:
1. Subclavian Artery: It is a major artery that supplies blood to the upper limb. It passes through the thoracic outlet and becomes the axillary artery.
2. Axillary Artery: It is located in the axilla and gives rise to several branches that supply the shoulder and upper arm.
3. Thoracoacromial Artery: It is a short artery that branches from the axillary artery and supplies the pectoral muscles and the acromion.
4. Posterior Circumflex Humeral Artery: It is a branch of the axillary artery that supplies the shoulder joint and surrounding muscles.
5. Anterior Circumflex Humeral Artery: It is another branch of the axillary artery that supplies the shoulder joint and deltoid muscle.
6. Brachial Artery: It is the main artery of the upper arm and continues into the forearm. It gives rise to several branches, including the profunda brachii artery.
7. Radial Artery: It is a major artery of the forearm that runs along the radial (thumb) side of the forearm, supplying the forearm muscles and forming the deep palmar arch.
8. Ulnar Artery: It is another major artery of the forearm that runs along the ulnar (pinky) side of the forearm, supplying the forearm muscles and forming the superficial and deep palmar arches.
Quick Review of upper limbs Nerves:
1. Suprascapular Nerve: It innervates the supraspinatus and infraspinatus muscles of the shoulder.
2. Subscapular Nerves (Upper and Lower): These nerves supply the subscapularis muscle.
3. Musculocutaneous Nerve: It innervates the muscles of the anterior compartment of the arm and provides sensory innervation to the lateral forearm.
4. Median Nerve: It supplies the muscles of the anterior compartment of the forearm, as well as the thenar muscles of the hand.
5. Ulnar Nerve: It innervates the muscles of the anterior and posterior compartments of the forearm, as well as the intrinsic muscles of the hand (except for the thenar muscles).
6. Radial Nerve: It supplies the muscles of the posterior compartment of the arm and forearm, as well as the posterior aspect of the hand.
7. Axillary Nerve: It innervates the deltoid muscle and teres minor muscle.
8. Brachial Plexus: It is a complex network of nerves formed by the anterior rami of spinal nerves C5-T1. It gives rise to the major nerves of the upper limb.
9. Medial Brachial Cutaneous Nerve: It provides sensory innervation to the medial aspect of the arm.
10. Medial Antebrachial Cutaneous Nerve: It provides sensory innervation to the medial aspect of the forearm.
