Upper limb Flashcards
How many layers for the anterior aspect of the forearm
4
the muscles of the first layer?
- Pronator teres
- Flexor carpi radialis
- Flexor carpi ulnaris
- Palmaris lonugs
the muscles of the second layer of the anterior aspect of the forearm
1.Flexor digitorum superficialis
Third layer?
- Flexor digitorum profundus
2. Flxor pollicis longus
Fourth layer
Pronator quadratus
Which muscle is innervated by median+ulnar nerve
Flexor digitorum profundus
Which muscle is innervated only by the Ulnar nerve
Flexor carpi ulnaris
How many muscles on the lateral aspect of the forearm
4
What are the muscles of the lateral aspect of the forearm?
- Brachioradialis
- Extensor carpi radialis longus
- Extensor carpi radialis brevis
- The supinator muscle
Dorsal scapular nerve innervates and emerges
emerges from the superior trunk of ht brachial plexus
- Rhomboid minor
- Rhomboid major
- levator scapulae
The suprascapular nerve
Arises from the superior trunk
- Infraspinatus muscle
- supranspinatus muscle.
- Shoulder joint
Long thoracic nerve
C5-C6-C7
1.Serratus anterior
Upper and lower supscapular nerve
Arise from the posterior cord
innervates the subscapularis muscle
Thoracodorsal nerve
orginates from the posterior cord
- Teres major
- Latissmus dorsi
Lateral pectoral nerve
from the name you can know it.
Arises from the lateral cord
1.Pectoralis major
2.Pectoralis minor
Medial pectoral nerve
Arises from medial cord
Innervates pectoralis minor and major
Pectoral loop is an anastomosis between
Lateral pectoral nerve and medial pectoral nerve
The cords of the brachial plexus are
- Posterior cord
- Medial cord
- lateral cord
Upper trunk gives us
Dorsal scapular nerve
The suprascapular nerve
The subclavian nerve
The posterior cord gives branches to
- Axillary nerve
- Radial nerve
- Upper and lower subscapularis
- Thoracodorsal nerve
Radial nerve is coming from which cord
Posterior cord
Branches of the radial nerve
- Posterior brachial cutaneous nerve
- Posterior antebrachial cutaneous nerve
- The superficial branch of the radial nerve
- The deep branch of the radial nerve
- Muscular branches
The median nerve arises from
the anastomoses of lateral and medial cords
Ulnar nerve arises from
medial cord
