| Question | Answer |
| How many bones does the skeleton contain? | 206 |
| what is contained in the axial? | skull, vertebral column, sternum, ribs |
| what is contained in the appendicular? | extremities and the appropriate girdles |
| Tuberosity | large bump (deltoid, tibial) |
| Tubercle | smaller bump (greater and lesser tubercles of humerus) |
| Process | projection (acromion, coracoid) |
| Spine or Spinous process | longer, thinner projection (scapula |
| Condyles | bony knobs at either end of a long bone (femoral) |
| Epicondyles | smaller knobs above condyles (humeral) |
| Fossa | smaller, flatter smooth surface (vertebral, prox. humerus) |
| Notch | allows passage of structures (scapular) |
| Foramen | hole, also allows passage of structures (obturator, skull) |
| Diathrodial | They have joint cavity and there are
6 subtypes |
| Synarthrodial | They have no separation, and there are 3 subtypes |
| what are the 3 types of Synarthrodial joints? | -cartilaginous joint
-sutured joint
-ligamentous joint |
| Hayaline/Articular cartilage | Protects ends of bone |
| Fibrous cartilage? | -Cushions impact
-Maintains bone position |
| Ligaments | bone to bone contact |
| what are he 6 types of diarthrodial joints? | -hinge joint
-ball and socket joint
- irregular joint
-condyloid joint
-saddle joint
-pivot joint |
| hinge joint | uniaxial |
| saddle joint | biaxial |
| ball and socket joint | multiaxial |
| plane joint | nonaxial |
| sagittal plane | front and back movement of the arm |
| frontal plane | arms flapping |
| transverse plane | twisting of the hip, hand, or shaking your head (rotation) |
| Bursa | -fibrous sac-like structure containing fluid
-decreases friction |
| Bursits | trauma to a bursa sac- can become inflamed |
