Q

What does the capsular ligament fuse and attaches with?

A

Fuses with the collateral ligaments
attaches to the tricep brachii muscles, olecranon, lateral epicondyle, in the area btw the humerus, trochlea, and the capitulum.

16
Q

The proximal and radioulnar joint is what?

A

A joint between the forearms head radius and the radial notch of the ulna

17
Q

What is the annular ligament?

A

A ligament that runs between the anterior and posterior edge of the radial notch of the ulna and forms a complete ring around the head radius

18
Q

a ligamentous band of connective teissues that runs between the shafts of the ulna and radius ligament

A

Interosseous ligament (also known as the interosseous membrane)

19
Q

What does the interosseous ligament do?

A

Help distributes pressure between the ulna and radius when force is applied and serves as place of attachment for muscles,

20
Q

Where is the oblique cord and what is it known for?

A

Its located at the proximal end of the interosseous ligament and it prevents the separation bwt the ulna and radius

21
Q

Where is a pivot joint formed at on the wrist?

A

In the conclave notch of the radius and where the round head of the ulna rotates at

22
Q

What is the starting position for describing all fundamental movements of any joint is?

A

The anatomical position

23
Q

What is an the uniaxial joint that is capable of flexion and extension in the sagittal about the frontal horizontal plane?

A

The elbow joint

24
Q

What are the five major muscles that produce motions of flexion and extension of the elbow joint?

A

Brachialis, Brachioradialis, bicep brachii- Flexion
tricep brachii and anconeus- Extension

25
Q

What four muscles are responsible for the movements of supination and pronation of the forearm?

A

Bicep brachii and Supinator- Supination

Pronator Quadratus and Pronator Teres- Pronation

26
Q

How many anterior muscles are there in the elbow and what are they?

A

Three; Brachialis, Brachioradialis, and Bicep Brachii

27
Q

Which anterior muscle is only involved with the elbow joint and its movement of the forearm?

A

Bicep Brachii

28
Q

What are the posterior muscles of the elbow?

A

Tricep Brachii and Anconeus

29
Q

True or False: The anconeus can perform both actions of elbow extension and movement of the forearm

A

False. It can only perform one action- elbow extension

30
Q

What are the muscles of the forearm?

A

Pronator Teres, Pronator Quadratus, Supinator, adn Bicep Brachii

31
Q

What can be known as little league elbow or Pitchers elbow?

A

The inflammation of the pronator flexor group at its origin in the area of the medial epicondyle of the humerus

32
Q

Who was able to make a substitution for a disruptive ligament and what is the procedure called?

A

Dr. Frank Jobe in 1974; The Tommy John Surgery

33
Q

What is tennis elbow?

A

An inflammation in the area of the supinator-extensor muscle group origin on the lateral epicondyle of the humerus
