Chapter 1 - Applied Anatomy And Physiology Flashcards
What is the skeleton?
- provides a framework for movement
- made up of bones and different joints
Musculoskeletal system
When the muscular system and the skeletal system work together to allow movement at joints
Flat bones
- Often quite large
- protect vital organs
- pelvis
- cranium
- scapula
- sternum
- ribs
- clavicle (collar bone)
- jaw bone
- talus
Long bones
- enable large movements
- femur (thigh bone)
- tibia (shin bone) & fibula
- metatarsals & phalanges (toes)
- radius & ulna
- humerus
- metacarpals & phalanges (fingers)
Short bones
- enable finer controlled movements
- tarsals
- carpals
Irregular bones
- shaped to protect
- vertebrae (protect spinal cord)
- patella
Articulating bones
Bones that meet at a joint to enable movement
Articulating bones at the shoulder
Scapula, clavicle, humerus
Articulating bones at the elbow
Humerus, radius, ulna
Articulating bones at the hips
Pelvis, femur
Articulating bones at the knee
Femur, patella, fibula, tibia
Articulating bones at the ankle
Tibia, fibula, talus
What are the 6 functions of the skeleton?
- Support
- Protection
- Movement
- Shape and structure
- Blood cell production
- Storage of minerals
Support of the skeleton
- Support for muscles and vital organs
- without support the body would be a mass of soft tissue and unable to move
Protection of vital organs
-reduces chance of injury during physical activity
Movement
- The ability to move is central to all physical activities
- occurs when muscles contract and pull on bones
