muscle of the forearm and cubital fossa Flashcards
how many muscles does the anterior compartment have
it consists of 8 muscles
what innervates these 8 muscles
the median and ulnar nerve
the 8 muscles are divided into 3 muscle groups what are they
-Superficial group with 4 muscles
- Intermediate group with 1 muscle
- Deep group with 3 muscles
what makes up the superficial group
-pronator teres muscle
-flexor carpi radialis muscle
-palmaris longus muscle
-flexor carpi ulnaris muscle
what makes up the intermediate group
-the flexor digitorium superficialis muscle
what makes up the deep group
-the flexor digitorum profundus muscle
-the flexor pollicis longus muscle
-the pronator quadratus muscle
what is the origin of the pronator teres muscle
the medial epicondyle and coronoid process of the ulna
where is the insertion in the pronator teres muscle
the lateral aspect of the shaft of the radius
what action does the pronator teres muscle do
pronation
where is the pronator teres muscle innervated
by the median nerve
the origin of the flexor carpi radialis muscle
the medial epicondyle of the humerus
what is the insertion point of the flexor carpi radialis muscle
the base of the second and third metacarpals
what is the action of the flexor carpi radialis muscle
flexion and abduction at the wrist joint
