Class 3 Flashcards
What are the superficial muscles of the anterior forearm
Pronator teres
Flexor carpi radialis
Palmaris longus
Flexor carpi ulnari
Where do the superficial muscles originate from
Medial epicondyle
What nerve innervates the superficial muscles
Median nerve
Ulnar nerve innervates flexor carpi ulnaris
What are the actions of the superficial anterior muscles
Pronator teres = pronation
Radialis = flexion of wrist + abduction
Palmaris longus = flexion of wrist
Ulnaris = flexion of wrist + adduction
What other superficial muscle is involved in flexion of elbow
Brachioradialis
Stands out when you flex against resistance
What innervates brachioradialis
Radial nerve
What is a sign that you are looking at superficial muscles
Cannot see nerves
What is the anterior intermediate muscle
Flexor digitorum superficialis
Where does FDS originate and attach and what is the actions
Originate from medial epicondyle
Attach to middle phalanges 2-5
Flex wrist, MCP and proximal IP
What innervates FDS
Median nerve
What are the deep muscle layers
Flexor digitorum profundas
Flexor polices longus
Pronator quadrates
Where does FDP originate and attach and action
Ulnar -> distal phalanges 2-5
ALL wrist and finger joints
Flexion
What innervates FDP
Medial 2 fingers = ulnar
Lateral 2 = median nerve
Where does FPL originate, attach and action
Radius -> distal plalanx of thumb
Flexion of MTP and IP
Median nerve
Where does pronator quadrates originate and attach and action and nerve suppy
Ulna - radius
Pronation
Median
