Test 3 Ch. 8-10 Flashcards
Radial nerve innervates this muscle.
triceps brachii
short head of biceps brachii attaches to
coracoid process of scapula
Key bony landmark for radius is
radial tuberosity
Two bones of radioulnar joint provides actions of
supination & pronation
Pronator quadratus is a small muscle located …. on the …. end of the forearm
distally, anterior
Proximal end of the brachioradialis attaches
lateral supracondylar ridge of humerus
Pronator teres performs pronation, but also assists in weak
flexion of elbow joint
Pronator teres is able to perform pronation because it inserts on
radius
Insertion of the supinator is on
lateral surface of the upper 1/3 of radius
Anconeus, triceps brachii, and supinator are located on
posterior region of the upper extremity
Action brachioradialis, brachialis, biceps brachii, and pronator teres have in common
flexion
Biceps brachii performs flexion best in what position
supinated
Triceps brachii and anconeus insert where
olecranon process of ulna
triceps brachii and anconeus are
synergists
Long head of triceps is located on
infraglenoid tubercle of scapula
Long head of the biceps brachii originates on
supraglenoid tubercle of scapula
Brachialis performs true …. as it inserts only on the ….
flexion, ulna
Brachioradialis inserts on
styloid process of radius
Muscles actively contracted on the anterior position of the humerus during flexion of elbow joint are …. and ….
biceps brachii, brachialis
Median nerve inflammation in the carpal tunnel is called
Carpal Tunnel Syndrome
The median nerve sits …. the tendon in the carpal tunnel.
on top of
Ulnar nerve compression often occurs when
ulnar nerve does not have enough room in the cubital tunnel
The cubital tunnel area is between the medial epicondyle and ….
olecranon process
The signs and symptoms of the subacute flare-up are
the same as the acute stage
The nerve that travels through the carpal tunnel
median nerve
The carpal bone located most centrally inferior to the 3rd phalange is ….
capitate
How many carpal bones form the wrist
8
What carpal bone if depressed can shrink the size of the carpal tunnel?
capitate
The distal interphalangeal joints are what type of joint.
hinge/ginglymus
The metacarpophalangeal joints or knuckles are what type of joint?
condyloid
The carpometacarpal joint of the thumb is a …. joint and can perform ….
saddle type, opposition
Muscle that inserts into the palmar aponeurosis of the hand, but does not go through the carpal tunnel ….
palmaris longus
Palmaris longus, flexor carpi radialis, and flexor carpi ulnaris all originate from
medial epicondyle
Proximal interphalangeal joints are what type of joint.
hinge/ginglymus
Pollicis in extensor pollicis longus or flexor pollicis longus means
thumb
The extensor radialis longus, extensor radialis brevis, and extensor ulnaris all originate from
lateral epicondyle of humerus
Flexor carpii radialis flexes the wrist and ….
abducts the hand at the wrist
Muscle that inserts at base of distal phalanges of four fingers
flexor digitorum profundus
Extensor pollicis brevis inserts
base of the proximal phalanx of thumb
Muscle that performs abduction of thumb
abductor pollicis longus
Extensor indicis literally means extending the ….
index finger
Extensor digitorum originates
lateral epicondyle of humerus
Flexor digitorum superficialis is above the …. muscle.
flexor digitorum profundus
To demonstrate flexion of the wrist the therapist would move the ….
palm of hand toward the anterior aspect of forearm.
The muscles of the elbow and radioulnar joints are all intervated from the median nerve, radial nerve & ….. of the brachial plexus
musculocutaneous
