of glenohumeral flexion in order to flex the elbow fully - ✔✔45 degrees
The main innervation for the elbow flexors is the - ✔✔Musculocutaneous nerve
An injury to the radial nerve would affect the - ✔✔Elbow and wrist extensors
Scapular abduction is aided by - ✔✔The upper and lower trapezius
What control movementsare used to operate a transradial prosthesis? -
✔✔Glenohumeral flexion and biscapular abduction
Biscapular abduction in transradial prosthesis is a control motion used for - ✔✔Activities
at the midline
It is a good reason to fit a child with an upper extremity prosthesis as early as possible because:

- ✔✔Trimlines that exclude the epicondyles
The Muenster type self suspending prosthesis - ✔✔- Limits range of motion no more
than 70%
- Used for short to very short trans-radial amputations
