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 |
