Unit 1: Skeletal System - Functions & Types Of Bone Flashcards
The skeleton has 7 functions. What are they?
- Provide Shape & Support 2. Movement / Leverage 3. Protection 4. Blood Cell Production 5. Mineral Storage 6. Attachment of Soft Tissue 7. Bone Growth
These cells are responsible for bone growth
Osteoblasts
What is a Long Bone, and what is its function?
Longer than wide; consisting of a hollow shaft of compact bone with enlarged ends made of spongy, cancellous bone. Function is to bear weight and provide leverage for movement
Describe the structure and function of an Irregular Bone
Variety of shapes, often randomly shaped. Have projections and processes. Various functions, including protection and muscle attachment. E.g., The Vertebrae
The longest bone of the body is…?
Femur
Where is the humerus found?
Upper arm (Basic) Superior arm, attaching at the shoulder girdle (Perfect!)
What 3 bones have fused to make up the pelvis?
- Ilium
- Ischium
- Pubis
What are the 5 regions of the vertebral column called?
- Cervical
- Thoracic
- Lumbar
- Sacrum / Sacral
- Coccyx
What type of bone is the scapula?
Flat bone
How does the skeletal system allow for the attachment of skeletal muscle?
Soft tissue attachment Bones have irregular shapes, often with bony points (protrusions) or grooves where muscles can attach
Give an example of how the skeleton protects us
- Cranium: natural crash helmet, protecting the brain
- Ribs: protect the lungs & heart Sternum: protects the heart
How does the skeleton produce blood cells
In the bone marrow, normally of long bones
What are the 2 parts of the human skeleton called?
What are the 3 regions of the hand?
- Carpals
- Metacarpals
- Phalanges
What are the 3 regions of the foot?
- Tarsals
- Metatarsals
- Phalanges
