| Eversion | Turning foot so sole faces outward.
🗑

| Plantar Flexion | Flexing foot toward sole; pointing toes.
🗑
|
||||
| Pronation | Turning hand so palm is downward (posterior).
🗑
|
||||
| Rotation | Moving part around a longitudinal axis; shaking head "no."
🗑
|
||||
| Supination | Turning hand so that palm faces upward.
🗑
|
||||
| Gliding | Flat bone surfaces move back and forth and side to side.
🗑
|
||||
| What joints have little or no movement? | Cartilaginous and Fibrous.
🗑
|
||||
| Ligament | Reinforces the fibrous capsule; help prevent dislocation of the joint.
🗑
|
||||
| Hyaline Cartilage | The connective tissue that keeps bone ends from crushing when they are compressed.
🗑
|
||||
| Synovial Fluid | The lubricant that minimizes friction and abrasion of joint surfaces.
🗑
|
||||
| Diaphysis | Shaft/body of the bone.
🗑
|
||||
| Endosteum | Lines medullary (marrow) cavity.
🗑
|
||||
| Calcification | Calcium connects with collagen fibers to harden bone.
🗑
|
||||
| Lamellae | Circular, ring-like matrix around a central canal. Concentric rings of calcified matrix.
🗑
|
||||
| What type of cartilage is involved in ossification? | Hyaline
🗑
|
||||
| Osteogenic Cells | Unspecialized stem cells; only cells that go under cell division.
🗑
|
||||
| Osteoblasts | Bone-building cells. "Good cells." Lay down additional matrix and become osteocytes.
🗑
|
||||
| Osteoclasts | Break down the matrix. Reabsorption.
🗑
|
||||
| If body Ca is too low... | PTH is released and osteoclasts break down bone and release Ca into the blood.
🗑
|
||||
| If body Ca is too high... | Ca is deposited into bone matrix as a salt after the bones become stronger and harder.
🗑
|
||||
| What shape is a short bone? | Cubical
🗑
|
||||
| Flat Bones | PROTECT organs. Skull, ribs, scapula, sternum.
🗑
|
||||
| Where is red bone marrow found? | Skull, ribs, sternum, clavicle. Makes RBC, WBC, platelets.
🗑
|
||||
| Foramen | Openings for blood vessels, ligaments, or nerves.
🗑
|
||||
| What is different between an adult and a baby cranium? | The baby's is more larger and disproportional to the rest of the skull.
🗑
|
||||
| What is the difference between Fibrous and Cartilaginous joints? | Fibrous are immovable. Cartilaginous is cartilage that connects bones.
🗑
|
||||
| Tendon | Muscle to bone.
🗑
|
||||
| Ligament--connects? | Bone to bone.
🗑
|
||||
| Axial Skeleton | Bones that lie vertically.
🗑
|
||||
| Appendicular Skeleton | Upper and lower limbs and girdles.
🗑
|
||||
| Fontanels | The soft spots on a young child's skull. Allow growth for skull as they are flexible and reshape once stopped growing.
🗑
|
||||
| Yellow Bone Marrow | Found in long bones, such as the arms and legs. Has fat (adipose) cells that are used in extreme hunger.
🗑
