Q

What is the Distal Transverse arch?

A

Located at the Metacarpophalangeal (MCP) joint level

The 1st, 4th, and 5th metacarpals rotate around the 2nd and 3rd metacarpals to either flatten or increase its arc.

27
What is abduction of the thumb?
Thumb in neutral position moving away from the other phalanges
28
What is adduction of the thumb?
Thumb in neutral position moving towards the other phalanges
29
What is extension of the thumb?
Thumb in anatomical position moving laterally away from the other fingers.
30
What is flexion of the thumb?
Thumb in anatomical position moving towards the palm and other fingers.
31
What is opposition of the thumb?
Thumb moving towards the pinkie.
32
What is reposition of the thumb?
Thumb moving away from the pinkie.
33
For forearm pronation and supination which bone rotates around the other?
The radius rotates around the ulna.
34
What types of synovial joints are found in the upper extremities?
Hinge joint Ball in Socket Condyloid Joint Saddle Joint
35
What is a condyloid joint?
Oval articular surface of one bone fits into complementary depression in another. Biaxial joints permit all angular motions
36
What are examples of condyloid joints?
Radiocarpal joints | MCP joints
37
What is a saddle joint?
Similar to condyloid joints but allow greater movement. Each articular surface has both a concave and convex surface.
38
What is an example of a saddle joint?
Carpometacarpal joint of the thumb
39
What is a hinge joint?
Cylindrical projections of one bone fits into a trough-shaped surface on another. Single plane of motion uniaxial joints permit flexion and extension only.
40
What are examples of hinge joints?
Elbow | Interphalangeal joints
41
What is the functional position of the thumb?
Thumb in abduction and opposition with the pads of the 1st and 2nd fingers in line with the pad of the thumb.
42
What occurs when the wrist becomes flexed?
The extensor tendons tighten and the distal transverse arch flattens.
43
What muscles cause flexion of the elbow?
``` Brachialis Biceps brachii Brachioradialis Pronator teres Extensor carpi radialis longus Flexor carpi radialis Flexor carpi ulnaris ```
44
What muscles cause extension of the elbow?
Triceps brachii | Anconeus
45
What is a ball in socket joint?
A spherical or hemispherical head of one bone articulates with a cuplike socket of another. Multiaxial joints permit the most freely moving synovial joints
46
What is an example of a ball in socket joint?
Glenohumeral joint
47
What is the functional position of the hand?
``` 30-40 degrees wrist extension 45-50 degrees MCP flexion 35-45 degrees PIP Flexion 10-25 degrees DIP Flexion 0-10 degrees Ulnar deviation ```
48
What are the pronator muscles of the forearm?
Pronator teres | Pronator quadratus
49
What are the supinator muscles of the forearm?
Biceps brachii | Supinator
50
What are the flexor muscles of the wrist?
``` Flexor carpi radialis Flexor carpi ulnaris Palmaris longus Flexor digitorum superficialis Flexor digitorum profundus ```

52
What are the Radial deviator muscles of the wrist?

What causes flexion of the distal interphalangeal joint?
Flexor digitorum profundus

63
What should be remembered about the Interossei?
``` Dorsal interossei (D.A.B.=Dorsal abducts the fingers) Palmar Interossei (P.A.D.= Palmar adducts the fingers) ```
