IV. Anatomy: Muscles
- Intrinsic (Originate in hand)
- General
- Delicate finger movements
- Thenar and Hypothenar Muscles
- Position thumb and small finger for pinching
- Interossei and Lumbricals
- Insert into proximal phalanges and extensor hoods
- Metacarpal phalangeal joint flexion
- Interphalangeal joint extension
- General
- Extrinsic (Originate in Forearm)
- Wrist flexors and extensors
- Stabilize wrist in slight dorsiflexion
- Finger Flexors
- Deep Flexors (5)
- Flex distal phalanges of fingers and thumb
- Superficial Flexors (4)
- Flex middle phalanges of fingers
- Course
- Under Annular ligaments (Pulleys)
- Between distal palmar crease and IP joint
- Conditions
- Deep Flexors (5)
- Finger Extensors
- Course dorsally over fingers and thumb
- Extend proximal phalanges
- Conditions
- Wrist flexors and extensors
V. Anatomy: Blood Supply
- Neurovascular bundles
- Contain digital artery, vein, and nerve
- Two bundles: one radial and the other ulnar
- Radial and Ulnar arteries join in 2 arches
- Superficial Palmar Arch: superficial to flexor tendon
- Located at base of first web space
- Deep Palmar Arch (deep to flexor tendons)
- Proximal to superficial arch by 1 cm
- Superficial Palmar Arch: superficial to flexor tendon
VI. Anatomy: Nerve
- Ulnar Nerve
- Median Nerve
- Motor
- Allows for fine control of pincer grasp
- Innervates thenar Muscles and two radial lumbricals
- Sensation
- Radial 3.5 fingers, and their dorsal tips
- Cutaneous innervation Image
- Course
- Passes via Carpal Tunnel through volar wrist
- Test function
- Opposition of thumb to each finger
- Observe thenar Muscles for contractions
- Conditions
- Motor
- Radial Nerve
- Motor
- Innervates extrinsic wrist and finger extensors
- Does not innervate any intrinsic Muscles
- Sensation
- Dorsally for 3.5 fingers
- Cutaneous innervation image
- Test function
- Wrist and hand extension against resistance
- Conditions
- Radial Tunnel (elbow)
- Handcuff Neuropathy (wrist)
- Motor
