Appendicular Skeleton - 🧠 ANSWER ✔✔Limbs, pectoral girdle, pelvic girdle
Functions of the Skeletal System - 🧠 ANSWER ✔✔1. Support
2. Movement/Locomotion
3. Storage of Ca and P04

5. Protection
What Makes Up Osseous Tissue? - 🧠 ANSWER ✔✔-Matrix of Bone
-Collagen fibers
-Bone Cells
Matrix of Bone consists of: - 🧠 ANSWER ✔✔- hydroxyapatite crystals
(Calcium Phosphate and Calcium Hydroxide)
- Enables bone to resists compression
- 2/3 of bone mass
Collagen Fibers: - 🧠 ANSWER ✔✔- makes up 1/3 of bone mass
- gives bone tensile strength
Bone Cells (Osteocytes and other cells) - 🧠 ANSWER ✔✔account for 2% of
bone mass
Osteocyte - 🧠 ANSWER ✔✔mature bone cell that maintains the bone
matrix
,Osteoprogenitor cell - 🧠 ANSWER ✔✔Stem cell that divides to produce
osteoblasts
Osteoblast - 🧠 ANSWER ✔✔Immature bone cell that secretes osteoid, the
organic bone matrix
Osteoclast - 🧠 ANSWER ✔✔multinucleate cell that secretes acid and
enzymes to dissolve bone matrix
Osseous Tissue Types - 🧠 ANSWER ✔✔compact bone and spongy bone
Compact bone - 🧠 ANSWER ✔✔-dense and solid
-forms walls of bone
-resists parallel compression
Spongy bone - 🧠 ANSWER ✔✔-surrounds medullary cavity
-resist multi directional or light strain
-open network of struts and plates
Epiphysis - 🧠 ANSWER ✔✔ends of long bones
Diaphysis - 🧠 ANSWER ✔✔shaft of long bones
Metaphysis - 🧠 ANSWER ✔✔transition between epiphysis and diaphysis

, Periosteum - 🧠 ANSWER ✔✔superficial layer of compact bone, everywhere
besides within a joint, multi cell layer
Functions of Periosteum - 🧠 ANSWER ✔✔- Isolates and protects bone from
surrounding
- Attachment for circulatory and nervous supply
- Bone growth and repair
- Attachment site for tendons and ligaments
Endosteum - 🧠 ANSWER ✔✔inside bone, lines the medullary cavity,
perforating canal, and central canal
Both the Endosteum and Periosteum have: - 🧠 ANSWER ✔✔- Osteoblast:
produces matrix
- Osteoprogenitor cells: produce osteoblasts
- Osteoclast: breakdown matrix
Appositional growth - 🧠 ANSWER ✔✔- Osteoblasts in periosteum add bone
to matrix to surface.
- Forming circumferential lamellae on out surface
- Osteons are formed
