Platysma
Bell of the foot corresponds to the:
Heads of metatarsals
Anconeus is responsible for:
a. helping maintain elbow extension
b. stabilizing the elbow joint during other movements of the UE
c. all of these
d. initiating extension of the elbow
ALL OF THESE
- Helping maintain elbow extension
- Stabilizing the elbow joint during other movements of the upper extremity.
- Initiating extension of the elbow
Muscle innervated by the radial nerve
a. FCR
b. FPL
c. FDS
d. APL
Abductor Pollicis Longus
Overlapping of receptive field improves this phenomenon sensation
Localization
The conoid and trapezoid are ligaments that connect the:
coracoids and clavicle
In the process of rising up from the sitting position, the following muscles are active, EXCEPT:
iliopsoas
The trapezius and serratus anterior:
acts as synergists in UPWARD ROTATION and antagonist in RETRACTION and PROTRACTION
in what movement of the scapula are the upper and lower trapezius muscles synergists:
upward rotation
in a midclavicular fracture, the structure that protects the underlying vessels from being injured is the:
subclavius
the highest content of elastic fiber is found in the ligament:
ligamentum flavum
NOT an extrinsic muscle of the hand:
a. EPL
b. ED
c. ECR
d. FDS
extensor carpi radialis
this does not describe the 7th rib
a. typical rib
b. has two demifacets on its head
c. longest rib
d. most oblique rib
most oblique rib (9th rib)
stimulation of the vagus nerve may be expected to result in
vasodilation and bradycardia
bradycardia is heart beats less than
60 per minute
N= 60-100bpm
interaction between actin and myosin filaments during muscle contraction is brought to a stop because of:
decrease concentration of intracellular calcium ions
a shunt muscle:
will usually have a long lever arm like the brachioradialis (for stability)
a house painter who often works with raised arms as the hands work at a height should primarily be given strengthening exercises for the:
serratus anterior (SH flex et UR)
efferent fibers of the muscle spindle come from the
gamma motor neuron
inability to make a complete fist with palmarflexion of the wrist is due to
passive insufficiency of the wrist extensors
muscle which has its distal attachment on the pisiform
flexor carpi ulnaris
the glenohumeral joint is most instable in this position
flexed, abducted, externally rotated (FABER)
the functional position of the deltoid ligaments are the following, EXCEPT:
lateral malleolus
deltoid ligaments:
ANTATI: ant. talotibial
POTATI: post. talotibial
CATI: calcaneotibial
TINA: tibial navicular
the attachment of the deltoid ligaments are the following, EXCEPT:
a. none of these
b. slight extension of the wrist to 40deg.
c. radial deviation to 5deg.
d. ulnar deviation to 15deg.
slight extension of the wrist to 40deg.
type of nerve fiber that has the fastest conduction:
large myelinated axons
this ligament does NOT contribute to the stability of the hip joint:
a. ischiofemoral ligament
b. ligamentum teres
c. pubofemoral ligament
d. iliofemoral ligament
ligamentum teres
this is a movement in the transverse plane
external rotation
the most commonly injured ligament of the ankle joint in the sprain is the
anterior talofibular ligament
with the forearm in the fully pronated position, flexion of the elbow is carried out mostly by the
brachialis
the biggest volume that can be expired by a person is called
vital capacity
the lumbrical muscle:
a. all of these are true
b. is the only intrinsic muscle responsible for MCP-flexion
c. together with the dorsal interossei, are primarily responsible for extension of the DIP joint
d. has a better leverage as a DIP extensor compared to its leverage as an MCP flexor
has a better leverage as a DIP extensor compared to its leverage as an MCP flexor
the blood supply of the posterior thigh muscles comes mainly from
profunda femoris artery
responsible for shoulder retraction
trapezius and rhomboids
a lesion of the subthalmic nucleus will result in
hemiballismus
triceps activity is enhanced by
elbow extension combined with shoulder flexion
