1
Q

Biceps Brachii and Brachialis muscles

A

Location: Cross the anterior elbow joint
Function: Flexion of the forearm

2
Q

Brachioradialis Muscle

A

Location: Descending on the lateral side of the forearm, inserts upon the styloid process of the radius
Function: Assisting the biceps brachii and brachialis in the flexion of the forearm

3
Q

5 Superficial Muscles Invovled in flexion or pronation

A

Alll attach to the medial epicondyle of the humerus, pronator teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris, flexor digitorum superficialis

4
Q

Pronator Teres

A

Function: rotates the palm backward

5
Q

Flexor Carpi Radialis

A

Function: flexes the wrist on the lateral side

6
Q

Palmaris Longus

A

Location: includes a long tendon which expands to form a dense connective tissue sheet (palmar aponeurosis) in the hand
Function: tense the palm and assists in flexion of the wrist.

7
Q

Flexor Carpi Ulnaris

A

Function: flexes the wrist on the medial side

8
Q

Fexlor Digitorum Superficialis

A

Location: sends tendons to the middle phalanx of the medial four digits (Index, long, ring and little fingers, but not the thumb)
Function: acts in flexion of the proximal and middle phalanges, and assists in the flexion of the wrist.

9
Q

MP Joints

A

moved in waving motions

10
Q

PIP joints

A

May also be independently moved with each digit flexing separately.

11
Q

Three deep muscles involved in flexion or pronation

A

Flexor pollicis longus, flexor digitorum profundus, pronator quadratus

12
Q

Flexor Pollicis Longus

A

Location: To the thumb distal phalanx
Function:

13
Q

Flexor Digitorum Profundus

A

Location: Distal phalanx of the medial four digits (Index, long, ring and little fingers)
Function: Allows (in some people) independent flexion of only the fingertips in these digits

14
Q

Pronator Quadratus

A

Location: Found near the wrist
Function: Flat square muscle, contracts with the pronator teres, in producing rotation of the hand, with the palm moving in a posterior (dorsal) direction

15
Q

Thenar Eminence

A

Two sets of intrinsic muscles that form the prominent bulge on the thumb side

16
Q

Hypothenar Eminence

A

Medial Side of the palm
