Brachial plexus Dr. Muhammad Bilal
Brachial plexus Definition Network of nerves formed by anterior rami of c5,c6,c7,c8, T1. Function:- 1-Sensory innervation to upper limb. 2- Motor innervation to upper limb & shoulder girdle except Trapezius. 3- Autonomic functions
Parts of Brachial plexus:- 1. Root 2. Trunk 3. Divisions 4. Cords 5. Branches Mnemonics Robert Taylor Drink Cold Beer
Location of Brachial plexus • Cervicobrachial position • Roots, Trunks, & Divisions located in posterior triangle of the neck. • Cords & branches located in the axilla
Location of the brachial plexus Clavicle divides the plexus into 2 parts Infraclavicular part i. Cords ii. Branches Supraclavicular part i. Roots ii. Trunks iii. Divisions
Relation with Axillary artery • The cords of the plexus are named according relationship with the second part of the Axillary artery • Brachial plexus + Axillary artery + vein are enclosed together in a connective tissue wrapping termed the axillary sheath. • The medial cord crosses behind the artery to reach the medial side of the second part of the artery . • Posterior cord lies behind the second part of the artery. • Lateral cord lies lateral to the second part of the artery
• Roots:- Anterior rami of C5,C6,C7,C8,T1. • Trunks:- 3 trunks I. Upper (2 branches) II. Middle III. Lower • Divisions:- 6 division I. 3 Anterior division from each trunk II. 3 Posterior division from each trunk • Cords:- 3 cords I. Lateral cord II. Medial cord III. Posterior cord • Branches:- 13 in numbers I. 5 branches medial cord II. 5 branches form posterior cord III. 3 branches from lateral cord.
Roots 5 nerves root C5-T1. 2 branches 1. Dorsal scapular nerve. 2. Long thoracic nerve. Dorsal scapular
Trunks Upper trunk Branches 1. Suprascapular nerve 2. Nerve to subclavius • Middle & lower Trunk no branch
Divisions 6 divisions of each truck 1. 3 Anterior division from upper, middle & lower trunk. 2. 3 Posterior division from upper, middle & lower trunk. No branch from division
Cords 3 Cords 1. Lateral cord :-anterior division of upper and middle trunk. 2. Posterior cord:- posterior division of all the 3 trunk. 3. Medial cord:- anterior division of lower trunk.
Branches Lateral cord 3 branches Lets musk let 1. Lateral pectoral 2. Musculocutaneous 3. Lateral root of median
Branches Posterior cord 5 branches ULTRA 1. Upper subscapular 2. Lower subscapular 3. Thoracodorsal nerve 4. Radial 5. Axillary
Branches Medial cord 5 branches Medals 4 u 1. Medial pectoral 2. Medial cutaneous nerve of arm 3. Medial cutaneous nerve of forearm 4. Medial root of median nerve 5. Ulnar nerve
The end
