1. What type of cartilage is this and where is it commonly found?

2. Name the origin and insertion of the triceps brachii.

3. Bob loves spending time in the Sun. Recently, he has observed that a mole on his palm has started growing. It is greater than 0.24 inches, is elevated and very firm. What disease does he have? (State the specific subtype)

1. Hyaline, commonly found in joints. 2. Not sure how specific you want, but the origin is the infraglenoid tubercule of the scapula and the insertion is the olecranon process of the ulna (had to look at cheat sheet for specifics). 3. I'd think it's malignant melanoma, probably the nodular type.

All correct, but for number 2: That was just the origin of the long head. The origin of the lateral head is the upper half posterior humerus and the medial head is deep on lower half posterior humerus inferomedial to spiral groove and both intermuscular septa.

Good to know.



1) What vertebra is pictured above?

2) A typical lumbar vertebra has…
a) A short, rounded spinous process.
b) A bifid spinous process.
c) Articulation sites for ribs.
d) transverse foramen.

3) How do the forms (shapes) of different vertebrae relate to their respective functions? (cervical, thoracic, lumbar)

2. a.
3. Cervical are small because they don't need to support much weight. Atlas and axis are very specialized for nodding and shaking your head no. Thoracic are larger and have facets for articulation with ribs. Lumbar are the largest with a large, thick body to support a lot of weight.

All good, your turn!

1. Label this bone:

2. What is the oxygen debt?

3. What do Pacinian corpuscles sense?

1. A - Clavicular Notch, B - Costal Notches, C - Xiphoid Process, D - Body, E - Sternal Angle, F - Manubrium, G - Jugular Notch 2. It's basically a deficit of oxygen after strenuous (anaerobic) exercise, due to a build-up of lactic acid levels. 3. Constantly changing deep touch.

All correct but for number 3, Pacinian corpuscles sense pressure and vibration. Your turn!

There's a lot of embedded questions, but give them a try:

1. What is DEXA (list its full form as well), what disease does it primarily diagnose, and what is the difference between a "t-score" and a "z-score"?

2. What causes skin to shrivel up in water? Why does this happen? What purpose does it serve?

3. Sort SO, FO, and FG muscle fibers into their respective alphanumeric types. Explain why you sorted this way. Which type has the most myoglobin? What is the purpose of myoglobin in these fibers? What replaces myoglobin in other fiber types?
