9.4 Superficial Muscle Of Front Of Forearm Flashcards
What is the most lateral superficial muscle of the front of the forearm?
Brachioradialis
True or False: The pronator teres is located on the medial side of the forearm.
True
Which muscle is primarily responsible for flexing the wrist?
Flexor carpi radialis
Fill in the blank: The __________ is the most medial muscle in the superficial layer of the anterior forearm.
Flexor carpi ulnaris
What muscle is located between the flexor carpi radialis and the palmaris longus?
Flexor digitorum superficialis
Which muscle has a tendon that passes through the carpal tunnel?
Flexor digitorum superficialis
True or False: The palmaris longus is absent in about 15% of the population.
True
What is the function of the flexor carpi ulnaris?
It flexes and adducts the wrist.
Identify the muscle that is primarily a weak flexor of the elbow and assists in forearm pronation.
Brachioradialis
Which two muscles originate from the medial epicondyle of the humerus?
Flexor carpi radialis and flexor carpi ulnaris
What is the primary action of the flexor digitorum superficialis?
Flexes the middle phalanges of the fingers.
Name the muscle that is the most superficial on the anterior forearm.
Palmaris longus
True or False: The brachioradialis is part of the superficial flexor group of the forearm.
False
Which muscle assists in flexing the wrist and is located on the radial side?
Flexor carpi radialis
What is the innervation of the flexor carpi ulnaris?
Ulnar nerve
Which muscle is absent in a significant portion of the population, making it a variable muscle?
Palmaris longus
Fill in the blank: The __________ is located just lateral to the flexor carpi ulnaris.
Flexor carpi radialis
What is the role of the pronator teres?
It pronates the forearm.
Which muscle is responsible for flexing the middle and proximal phalanges?
Flexor digitorum superficialis
Identify the muscle that contributes to wrist flexion and is positioned medially.
Flexor carpi ulnaris
True or False: The flexor digitorum superficialis has four tendons that extend to the fingers.
True
What is the common origin point for most superficial flexor muscles of the forearm?
Medial epicondyle of the humerus
What action does the flexor carpi radialis perform?
Flexes and abducts the wrist.
Identify the muscle that lies directly medial to the flexor carpi radialis.
Palmaris longus
Which muscle is primarily involved in the flexion of the elbow?
Brachioradialis
True or False: The superficial muscles of the forearm are primarily innervated by the radial nerve.
False
