Overview Of The Skeleton Flashcards
Name the six main functions of the skeleton
- Support
- Protection
- Movement
- Mineral homeostasis
- Triglyceride storage
- Blood cell production
State how support is a function of the skeleton
Provides structural framework to support soft tissues and provide attachment points for tendons and most skeletal muscles
State how mineral homeostasis is a function of the skeleton
It stores calcium and phosphorus and are released from the bone into the blood on demand
What two minerals contribute to bone strength
Calcium and phosphorus
State how triglyceride storage is a function of the skeleton
Adipose cells in yellow bone marrow store triglycerides
State how blood cell production is a function of the skeleton
Haemopoiesis occurs in red bone marrow in the developing of bones of the foetus and some adult bones
Who has more bones
Infants and children - bones fuse together as they get older
What are the two visions the adult skeleton is grouped in
- Axial skeleton
- Appendicular skeleton
What does the axial skeleton consist of
Skull, spine and thoracic rib cage
How many bones are there in the axial skeleton
80
polydactyly
addition of a finger or a toe
examples of irregular bones
coccyx
vertebra
zygoma
maxilla
sphenoid
temporal
mandible
hyoid
examples of flat bones
scapula
sternum
rib
cranial bones
examples of short bones
carpal bones
tarsal bones
