21
what are the primary and secondary flexors of the elbow?
primary
(1) biceps
(2) brachialis
(3) brachioradialis
secondary
(1) pronator teres
(2) ECRL
22
what position is the biceps brachii stronger as a flexor of the forearm?
supinated (think biceps curl)
23
in addition to flexing the forearm, what does the biceps brachii flex?
the long head flexes the shoulder
24
what are the primary and secondary extensors of the elbow?
primary
(1) triceps
secondary
(1) anconeus
25
what are the primary and secondary pronators of the elbow?
primary
(1) pronator teres
(2) pronator quadratus
secondary
(1) flexor carpi radialis
(2) brachioradialis
26
what are the primary supinators of the elbow?
primary
(1) biceps brachii
(2) supinator
27
what are the primary and secondary flexors of the wrist?
primary
(1) flexor carpi radialis
(2) flexor carpi ulnaris
(3) palmaris longus
secondary
(1) flexor digitorum superficialis
(2) flexor digitorum profundus
28
what are the primary and secondary extensors of the wrist?
primary
(1) ECRL
(2) ECRB
(3) extensor carpi ulnaris
secondary
(1) extensor digitorum
(2) extensor digiti minimi
(3) extensor indicis

(1) extensor carpi ulnaris
(2) flexor carpi ulnaris
secondary
(1) extensor digiti minimi
(2) flexor digitorum profundus
30

31
chronic nerve inflammation may lead to what in areas of the skin innervated by sensory nerves?
hypersensitivity and allodynia
32
what is allodynia?
pain with touch
33
what is a myotome?
a muscle or group of muscles served by a single nerve root
34
what is a dermatome?
the area of skin supplied by a single nerve root
35
what is a sclerotome?
area of bone or fascia supplied by a single nerve root
36
what is a deep tendon reflex (DTR)?
a brisk contraction of a muscle in response to a sudden stretch induced by a sharp tap on the tendon at the insertion of the muscle
37
how are myotomes graded?
0-5; same as MMTs
38
what do myotomes test?
gross muscle movements, not individual muscles
39
what is hyporeflexia?
an absent or diminished response to DTR
40
what is hyperreflexia?
the hyperactive or repeating (clonic) response to DTR
41
how do you grade DTR?
Grade 0 = no response; always abnormal
Grade 1 = a slight but definitely present response; may or may not be normal
Grade 2 = a brisk response; normal
Grade 3 = a very brisk response; may or may not be normal
Grade 4 = hypertonic. a tap elicits a repeating reflex (clonus); always abnormal
42
how to differentiate between a spinal nerve and peripheral nerve issue?
muscular issues
-if a gross movement is affected, more likely to be myotome or SPINAL nerve
-if an individual muscle is affected (using MMT), more likely to be a PERIPHERAL nerve
43
when hyperreflexia presents, where does that indicate the lesion is located?
CNS Lesion
44
when hyporeflexia presents, where does that indicate the lesion is located?
Peripheral Nerve lesion
45
