Big Picture
The elbow is this kind of joint
What is a Pivot
What is an Interosseous Membrane, which will transmit force from one bone to another.
All the flexors of the forearm come from this boney landmark
What is the medial epicondyle
What 3 muscles in the superficial layer are innervated by the median nerve.
What are Pronator Teres, Palmaris Longus and Flexor Carpi Radialis.
Which of these 3 is the most powerful?
These 2 muscles both cause wrist extension and radial deviation
Extensor Carpi Radialis Longus (base of 2nd metacarpal) and Extensor Carpi Radialis Brevis (base of 3rd metacarpal)
The carrying angle is larger in females. True or False?
True
Bicep Brachii and the Lateral Head of the Triceps share these type of characteristics/functions
What are Fast twitch muscles, powerhouses, quick to fatigue
False. The flexor compartment has 3 (superficial, intermediate and deep) and the extensor compartment has 2 (superficial and deep)
What is the only muscle in the superficial layer to not travel down to the wrist?
Pronator Teres
These 2 muscles both move from the lateral epicondyle, along the posterior forearm and attach to the base of the middle phalanges of digits 2-5 or just the 5th digit.
Extensor Digitorum (Communis) and Extensor Digiti Minimi
Tommy John syndrome would happen at this ligament
What is the medial Collateral Ligament
This muscle stabilizes your elbow, and can prevent flexion
What is the Aconeous
The flexor digitorum superficialis is in this layer of the forearm muscles.
What is Intermediate
This muscles starts at the medial epicondyle, and through the carpal tunnel, and attaches to the middle phalanges. It is powerful. And reaches everything but the DIP
Flexor Digitorum Superficialis
This muscle attaches to the radial styloid process and is the closest extensor muscle to the flexor compartment.
Brachioradialis. It is an elbow flexor
The radius and humerus are in contact while one's arm is at rest. True of False?
False, the are only in contact during weight bearing times
These are slow twitch muscles, are slow to fatigue and always are active when the arm is moving.
What are brachialis and the short head of the triceps
This long muscle tendon is commonly used for graphs
What is the Palmaris Longus
Flexor Carpi Radialis starts at the medial epicondyle and goes all the way to these structures. And at the wrist it runs next to this.
What are the base of the second and third metacarpals. The radial artery
This deep extensor muscle loops around the radius, extends MCPs not IPs, and travels around the thumb.
Extensor Pollicis Brevis
The Anular ligament is lined with this. And what does it do?
What is hyaline cartilage. It reduces friction
This is where to Palmar and Dorsal Radio-Ulnar ligaments attach
What is the unlar styloid process to unlar notch
These 2 muscles in the deep flexor compartment are innervated by the Anterior Interosseous nerve
What are the Flexor Pollicis Longus and the Pronator Quadratus
This muscle is Deep to Flexor Digitorum Superficialis in the arm and hand. Reaches the DIP of the fingers. Flexes all joints in the hand. Adds precision
What is the Flexor Digitorum Profundus
This muscle is deep to extensor digitorum, close to the ulna, and extends MCPs
