humerus
on the posterior - The_________extends the humerus.

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.

humerus
delotoid, subscapularis, supraspinatus, infraspinatus, teres minor
Muscles that attach the axial skeleton to the
pectoral girdle (shoulder)
trapezius, pectoralis major, serratus anterior

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.
