Label the diagram of the **Distal end of the Humerus**
26
CN: Describe the expression "funny bone"
The groove for the **unlar n.** houses the **unlar n.** and when it is compressed, it is painful. THIS! Is the origin of the expression "funny bone"; relates to the presence of the Ulnar N. in this groove on the humerus=funny
27
CN: Describe an **Avulsion fracture** of the **Medial Humeral Epicondyle**
Severe **ABDUCTION** of the elbow Leads to a piece breaking off epicondyle
28
Label the diagram of the **Distal end** of the **Humerus**

40
Label the diagram of the **Distal Radius**
41
CN: What is **Colle's Fracture?**
Fractures of the **Distal end of the radius**
42
What are these bones?
CARPALS 8 of them!
43
Label the **Carpal** bones
44
What are the bones of the **proximal row** of the **Carpal B.?**
1. Scaphoid 2. Lunate 3. Triquetrum 4. Pisiform
45
What are the bones of the **distal row** of the **Carpal B**.?
1. Trapezium 2. Trapezoid 3. Capitate 4. Hamate
46
CN: Which is the most commonly fractured Carpal Bone?
Scaphoid
47
Label the **Anterior Aspect** of the **Carpal Bones**
48
CN: Describe what the carpal tunnel is
The passage **anterior** to the **carpal bones** AND **posterior** to the **flexor retinaculum**
49
CN: If swelling occurs in the carpal tunnel, what is likely to happen?
Median N. can be compressed resulting in **carpal tunnel syndrome** \*produces, parasthesia, anesthesia and pain
50
CN: The **carpal tunnel** transmits the following tendons:
- Flexor digitorum profundus - Flexor digitorum superficialis - Flexor carpi radialis t. - Median N.
51
CN: What is **Guyon Tunnel** referring to?
Unlar Canal: The depression b/w the **Pisiform** and **Hamate**
52
CN: What is **Guyon's Canal Syndrome?**
When **ULNAR N.** compressed, causes a loss of sensation and muscular weakness "aka, handlebar neuropathy"
53

At the THUMB! That's number 1
54
What is the only metacarpal with something "interesting" occuring?
3rd Metacarpal Has styoloid process on it's base
55
CN: Describe **Boxer's Fracture**
The head of the **5th Metacarpal** is susceptible to fracture when an individual punches something with a closed fist
