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 |
