Skeletal System - answer✔Bones + Cartilage
Location: Hyaline Cartliage - answer✔Costal Cartilage, nose, articular joints (ends of long
bones), embryonic skeleton, respiratory structures (larynx), growth plates.
*most predominate type of carliage
Location: Fibrocartilage - answer✔Pubic Symphysis, vertebral discs, meniscus (knee)
Location: Elastic Cartilage - answer✔Epiglottis and outter ear (finnas)
Cartilage Properties - answer✔-CT
-Lots of extracellular matrix (gel-like and some fibers)
-Chondrocytes (most predominate cell) within lacuna
Facts about Fibrocartilage - answer✔-rows of round chondrocytes + parallel collagen fibers
-inbetween hyaline and dense regular tissue
Function of Bones - answer✔-support
-Protect
-Movement
-Mineral Storage (calcium and phosphates)
-hemopoiesis (red bone marrow)
-Energy Storage (yellow bone marrow)
-metabolism (regulates insulin and fat storage)

Flat Bones - answer✔-thin, flattened, curved
-cranial bones
-ribs
-sternum
-scapula
Irregular - answer✔-Various shapes
-vertebrae
-Os Coxae
Short bones - answer✔-Roughly cube shaped
-carpals/ tarsals
-sesamoid bones (within tendons, ie L & R patella)
Compact Bone - answer✔Aka cortical bone. Covers spongy bone
Spongy Bone - answer✔aka trabecular aka cancellous. larger space within, houses marrow
usually at ends
Diaphysis - answer✔shaft of long bone
Epiphysis - answer✔two distinct ends of long bone
Articular cartilage - answer✔covers the epiphysis, made of hyaline cartilage
Metaphysis - answer✔regions where diaphysis joins epiphysis. Usually has the epiphyseal line
there, previously the growth plate.
epiphyseal line - answer✔remnant of epiphyseal plate aka growth plate (disc of hyaline). Used
for bone growth during development
