Skeletal System Flashcards
1. Osseous Tissue 2. Axial Skeletal System (Skull Bones/Markings, Vertebral Column, & Thoracic Cage) 3. Appendicular Skeletal System (Shoulder/Pelvic Girdle & Upper/Lower Appendicular Skeleton)
OSSEOUS TISSUE
What is the composite material that makes up bone?
(hint: 2)
- Collagen
- Hydroxyapatite
1. Collagen provides resiliency/flexibility
2. Hydroxyapatite provides hard/rigid structure
OSSEOUS TISSUE
What specialized property does bone have during its remodeling?
Piezoelectric effect
The piezoelectric effect (in bones) refers to the ability to convert mechanical stress into electrical potentials. These electrical potentials illicit responses to rebuild bones in said areas of compression
OSSEOUS TISSUE
If a person’s bone easily shatters (i.e., in older people), what composite material of bones are they missing?
collagen
Dr. Glass has a collgen deficiency
OSSEOUS TISSUE
Do bones regrow? Why?
Yes, due to the piezoelectric nature of bones
OSSEOUS TISSUE
What are the functions of osteoclasts?
Break down broken bones
OSSEOUS TISSUE
What are the function of osteoblasts?
Synthesize new bones
OSSEOUS TISSUE
Where are osteocytes (bone cells) found?
osteocytes are living bone cells
lacuna(e)
osteocytes are stuck in composite of hydroxyapatite and collagen matrix inside lacunae

IDENTIFYING VERTEBRA
How do you distinguish if a vertebra is a part of the cervical vertebral column?
(hint: 2)
C1-C7
- A bifid spinous process
- Bilateral transverse foramen
IDENTIFYING VERTEBRA
How do you distinguish if a vertebra is a part of the thoracic vertebral column?
(hint: 2)
(T1-T12)
- The spinous process is pointed downwards
- It has superior, inferior, and transverse costal facets (bilaterally) in order to articulate with ribs
IDENTIFYING VERTEBRA
How do you distinguish if a vertebra is a part of the lumbar vertebral column?
(hint:
L1-L5
- The spinous process is wide and protudes outwards (with no angularture)
