Regions of Upper Limb

Upper limb consists of four regions: arm, forearm, wrist, and hand

Bones of Upper Limb

Bones of upper limb include humerus, radius, and ulna

Muscles of Upper Limb

Muscles involved in movement of arm:
- Flexion: deltoid, coracobrachialis, pectoralis major
- Extension: triceps brachii
- Abduction: deltoid
- Adduction: pectoralis major, deltoid
- Rotator cuff muscles: deltoid, supraspinatus, etc.
Muscles involved in movement of forearm:
- Flexion: biceps brachii, brachialis
- Extension: triceps brachii

Muscles of Forearm

Muscles of anterior compartment of forearm:
- Superficial muscles: flexor digitorum superficialis, etc.
- Deep muscles: flexor pollicis longus, flexor digitorum profundus, etc.
Muscles of posterior compartment of forearm:
- Superficial muscles: extensor digitorum communis, etc.
- Deep muscles: extensor pollicis longus, extensor indicis, etc.

Carpal Tunnel Syndrome

Carpal tunnel contains tendons from flexor pollicis longus, flexor digitorum profundus, and flexor digitorum superficialis
Awkward postures or repetitive hand movements can cause irritation and inflammation of tendons
Swelling of tendons can compress the median nerve, leading to pain at the wrist region

Cubital Fossa and Brachial Artery

Cubital fossa is a triangular region in the anterior aspect of the elbow
Brachial artery is located in the cubital fossa

This quiz covers the different regions, bones, and muscles of the upper limb, including their roles in movement and relation to conditions like carpal tunnel syndrome. Test your knowledge of the upper limb anatomy.
