Shapes of Bones
This bone of the hand is a long bone
Phalanges
Long bones are formed through what pathway
Endochondral
This type of bone is located in the outer region
Cortical (compact/lamellar)
The part of the hair strand that is visible
Shaft
The prefix Chondro means what?
cartilage
The vertebrae are what shape of bone
Irregular
Flat bones are formed through which pathway
intramembranous
This is the structural unit of compact bone
Osteon
Name 3 functions of the hypodermis
Subcutaneous fat, Thermoregulation, Nutrient storage, Absorption of impact forces, Adhering skin to general area
This cell produces matrix
Chondroblasts
The bones of the skull are majority of what shape
Flat
in this pathway bone is laid on top of a cartilage matrix
Intramembranous ossification
This type of bone is characterized by "struts"
Spongy (cancellous/trabeculae)
This gland is associated with body odor
Apocrine
This helps resist compressive forces
collagen fibers
The coccyx is what shape?
Irregular
once the epiphyseal plates are fully ossified
These are small canals that branch between lacunae across the lamellae
Canaliculi
Which part of the epithelium is vascularized and innervated?
Dermis
Bone matrix is made up of what?
80% H2O
20% protein fibers (collagen or elastic)
Chondroitin and hyaluronic acid
The patella is what type
sesamoid
This type of growth is characterized by border cells differentiating and adding matrix onto existing cartilage matrix
appositional growth
This type of lamellae is formed between osteons
Interstitial lamellae
This sensory receptor is responsible for pain receptor.
Noci
Can cartilage repair itself? explain your answer.
Yes, cartilage can repair itself. However, this is done extremely slowly due to vascularization. In most cases of injury surgical intervention is needed.
