Need to know- fun facts
Functions of the Skeletal system
100
What is Periosteum?
tough, fibrous membrane that covers and protects the outer surface of bone
100
What system does the skeletal system work with for movement?
The skeletal system works with the muscular system to allow for movement.
100
How are joints classified?
Function- range of motion
Structure- material that holds the joints together
100
How many bones does the adult human skeleton have?
206
100
What does the skeletal system store?
The interior of the bone can store minerals (calcium, phosphorus) and chemical energy (fatty acids)
200
What are the main organs of the skeletal system?
Bones and joints
200
Who is this?
Tung Tung Sahur
200
What are the layers of the skeletal system?
Compact bone- dense and tough outer layer
spongy bone- lighter and slightly flexible
bone marrow- jelly like,
200
How does the skeletal system help us maintain homeostasis?
Bones are able to absorb or release calcium into the blood to maintain a stable environment in the body.
200
How does the skeletal system help with production of blood cells?
Red bone marrow inside some larger bones produces blood cells as well as many other types of cells.
300
What is compact bone?
Makes up the dense outer layer of bone.
300
What organs might the ribs protect?
heart and lungs
300
What are the axial and appendicular parts of the skeletal system?
Appendicular- 126 bones oif the appendages (arms and legs) and the girdles (shoulder and pelvic) that connect them with the axial skeleton and provide support and flexibility
Axial- 80 bones along the axis of the body which protect the internal organs
300
Whats the main differences between the male and female skeletons?
Difference found at the pelvis
Female skeletons are not as massive
Female thoracic rib cage is more rounded and smaller
300
What do ligaments do?
What do tendons do?
ligaments- Attach bone to bone
tendons- Attach muscles to bone
400
What is connective tissue?
Densely layered collagen fibers
400
How does the skeletal system work with the muscular system?
Musles are attached to bones with tendons and ligaments
When the muscle is contracted, the skeletal system can move
400
What are some ways that bones can be classified?
- Long bones
-Short bones
- Irregular bones
- Flat bones
- Sesamoid bones
400
How many pounds of pressure would it take to break a bone?
25-160
400
What part do joints play in the skeletal system?
They hold the skeleton together and support movement
500
What is spongy bone?
found inside bones and is lighter and less dense than compact bone because it is porous
500
What does the vertebrae protect?
The spinal cord
500
What is the difference between Exoskeletons and Endoskeletons?
External: made up of chitin and calcium cartbonate that provides protection to creatures such as insects and crustacea
Internal: skeleton of an animal that is comprised of bone and cartilage
500
What are some diseases of the skeletal system?
osteoporosis- loss of bone tissue
osteomalacia- softening of bones associated with vitamin d deficiency
arthritis- inflammatory disease that damages joints and surrounding tissue
Scoliosis- side to side curve of the spine
bone cancers
Breaks strains and fractures
500
What is the primary function of the skeletal system? At least one.
- The primary function is to form a solid framework of bones and connective tissues to support the body
-Protects the body tissues and internal organs
- Anchors the skeletal muscles
