(OAF)

25

What spinal nerve roots make up the brachial plexus?

C5, C6, C7, C8, T1 spinal roots.

26

How is the elbow joint stabilised? It rarely dislocates

-The elbow has a large amount of bony surface area contact between the trochlea of the humerus and the proximal ulna, all the way through its range of flexion and extension.
-The elbow has both medial and lateral collateral ligaments which are each a fan shape from the epicondyles of the humerus to the radius and the ulna

27

What is the carpal tunnel? What structures pass through it?

-Inclosed tunnel of carpal bones
-Median Nerve, Flexor Retinaculum, Opponens Pollicis, Carpal Bones, Flexor Tendons pass through.

28

Why do we have three elbow flexors? Explain what each one does.

-Required when forearm is pronated or supinated
Biceps: Elbow Flexion
Brachialis: Elbow Flexion
Brachioradialis: Elbow Flexion

29

Which dislocates more, the shoulder or the hip. Why is this?

The shoulder because:
-It has a greater range of motion so more range where there is less bone contact
-The glenohumeral ligaments are not as short or tight or strong as the iliofemoral, ischiofemoral or pubofemoral ligaments
-The acetabulum is deeper than the glenoid fossa so there is more bone to bone contact
-The hip is made for weight-bearing more than mobility, it attaches to the pelvic girdle whereas the shoulder only attaches to the clavicle and scapula

30

What muscles retract the scapula?

-Rhomboid Major
-Rhomboid Minor

31

What is the common extensor origin?

The lateral epicondyle of humerus

32

What is the common flexor origin?

The medial epicondyle of humerus
