HESI: SKELETAL
| Question | Answer |
|---|---|
| AXIAL SKELETON | HRS2V; H=HYOID; R=RIBS; S=SKULL, STERNUM; V=VERTEBRAL |
| APPENDICULAR SKELETON | PUPL; P - PECTORAL GIRDLE; U=Upper Limbs; P=Pelvic Girdle; L=Lower Limb |
| LONG BONES | LAF2T; L=LEG; A=Arm; F=Finger, Forearm; T=Thigh |
| SHORT BONES | SAW; A=Ankle; W=Wrist |
| FLAT BONES | SCRS; S=STERNUM; C=CRANIUM; R=Ribs; S=SCAPULAE |
| IRREGULAR BONES | PSF; P=Pelvic Girdle; S=Skull(floor); F=Face |
| complex salt of Ca(PO4)3 & CaCO3 | HYDROXYAPATITE |
| Proximal & Distal Ends of Bones | Epiphyses |
| Bone Shaft | Diaphysis |
| most common bone | LONG BONES |
| Medullary Cavity | where Red & Yellow Bone Marrow are located |
| Red Marrow | Hematopoietic (RBC forming) |
| Yellow Marrow | Adipose containing |
| PERIOSTEUM | anchor pt for Tendons & Ligaments |
| Connect Muscle to Bone | Tendons |
| Connect Bone to Bone | Ligaments |
| Mature Bones Cells | Osteocytes |
| site where Osteocytes are housed | LACUNAE |
| site where blood vessels & nerves are housed in bone tissue | Haversian Canal |
| hard, outside of bone | Compact Bone |
| inner, cancellous bone | Spongy Bone |
| make up Spongy Bone | Trabecullae |
| where are osteocytes most comon | Compact Bone |
| produce new bone | Osteoblasts |
| involved in bone reabsorption | Osteoclasts |
| joints allows movement btw 2 flat surfaces | Plane or Gliding Joints |
| joints allow for angular movement | Hinge Joints |
| example of Hinge Joints | Elbow & Knee |
| joints allow for rotational movement btw 2 bones | Pivot Joints |
| example of Pivot Joints | Atlas/Axis - shaking head to say "NO" |
| joints that consist of spherical head in a round concavity | Ball & Socket Joints |
| exp of Ball & Socket Joints | Shoulder & Hip |
| decrease in joint angle from anatomical position | Flexion |
| e.g. of Flexion | bend your elbow up, means you're flexing A FOREARM |
| return to anatomical position | Extension |
| looking @ your toes | Flexing your head |
| returning head back to anatomical position | Extending your head |
| HYPEREXTENSION | rolling a bowling ball & arm reaches very back of arc |
| movement of limbs AWAY from body in coronal plane | ABDUCTION |
| movement of limbs back to anatomical position | ADDUCTION |
| circular movement of body part | ROTATION |
| Lateral Rotation | move (anterior surface) limbs to side (away from body) |
| Medial Rotation | move (anterior surface) limbs toward body |
| lateral rotation of hand = anatomical position | Supination |
| medial rotation of hand | Pronation |
