MODULE 4 MUSCLES PT 2 Flashcards
triangle muscle at the back
trapezius muscle
The ______ and the _________ are anterior muscles that attach the axial skeleton, via
the rib cage, to the pectoral girdle.
pectoralis minor, serratus anterior
The pectoralis major flexes the
humerus
on the posterior - The_________extends the humerus.
latissimus dorsi
There is one main superficial muscle that moves the humerus and stabilizes the glenohumeral joint:
the deltoid.
The biceps brachii ___the forearm,
while the triceps brachii ___the forearm.
flexes, extends
ANT: The_______and ________muscles flex the wrist and have a common origin on
the medial epicondyle of the humerus.
flexor carpi radialis , flexor carpi ulnaris
POST: The _____and ____, and the extensor carpi ulnaris muscles extend the wrist.
Their common origin is on the lateral epicondyle of the humerus.
extensor carpi radialis longus , brevis,
Muscles that move the forearm
biceps brachii, triceps brachii
Muscles that attach the axial skeleton to the arm
(humerus)
pectoralis major, lattissimus dorsi
Muscles that attach the pectoral girdle to the
humerus
delotoid, subscapularis, supraspinatus, infraspinatus, teres minor
Muscles that attach the axial skeleton to the
pectoral girdle (shoulder)
trapezius, pectoralis major, serratus anterior
Muscles that move the wrist
Extensor carpi radialis longus and brevis,
extensor carpi ulnaris, flexor carpi ulnaris
ANT - The ___-muscle flexes the thigh
iliopsoas
The muscles of the gluteal region extend the thigh. There are three gluteal muscles:
- Gluteus maximus
- Gluteus medius
- Gluteus minimus
are a group of muscles in the medial compartment of the thigh that function mainly to move
the thigh medially with a minor involvement in the movement of the leg by a single muscle component.
Adductors
post - The ____muscles make up the posterior compartment of the thigh. Together these muscles act
to extend the hip and flex the knee.
hamstrings
muscles make up the anterior compartment of the thigh.
The sartorius and quadriceps
the sartorius
crosses the hip and the knee, acting to ___both these joints
flex
The ____muscles solely act on the
knee, as they originate below the hip joint. They act together to extend the knee.
quadriceps
The _____extends the foot (dorsiflexion)
tibialis anterior muscle
The __muscles evert the foot.
peroneus (fibularis) longus
POST: The posterior compartment muscles are those that flex the foot (plantar flexion). THEY INCLUDE THE
Gastrocnemius
* Soleus (immediately deep to gastrocnemius) - TOGETHER FORM ACHILLES TENDON
Muscles that move the ankle and foot-posterior
Gastrocnemius, soleus
Muscles that move the leg-posterior
HAMSTRING
Muscle(s) that move(s) the ankle and foot-anterior
Tibialis anterior
Muscles that move the thigh-posterior
Gluteus maximus, gluteus medius/ minimus
Muscle(s) that move(s) the ankle and foot-lateral
Peroneus longus
Muscle(s) that move(s) the thigh-anterior
lliopsoas
Muscles that move the thigh-medial
Adductors
