Kin Flashcards
What is kinesiology?
The study of human movement
Anatomy
The study of body structure
Flexion
Decreasing the angle between two body parts
Extension
Increasing the angle between two body parts
Abduction
Moving a limb away from the bodies midline
Adduction
Moving a limb towards the bodies midline
Pronation
Rotating the forearm, so the palm faces downward
Supination
Rotating the forearms, so the palm faces upwards
Sagittal plane
Divide the body into left and right halves
Frontal plain
Divide the body into front and back halves
Transverse plane
Divide the body into top and bottom halves
Agonist
The muscle primarily responsible for movement
Antagonist
The muscle that opposes the prime mover
Cartilage
A smooth rubbery tissue that cushions joints
Ligament
Connect bone to bone
Tendon
Connect muscle to bone
The four roles of the skeleton
- Support and movement: the skeleton provides a frame to which our muscles and organs attach
- Protection: the skeleton is the bodies armor.
- Blood cell factory: our bone marrow creates our blood cells
- Warehouse: bone minerals, such as calcium, which is essential for bone formation.
How many bones do we have?
Humans have 206 bones, but are born with more than 300
Axital
The axital skeleton is similar to the frame of a car in that all major parts are attached (spine, ribs, pelvis, head)
Appendicular
The appendicular skeleton consists of the bones that connect to the axital skeleton, similar to the car doors due on a car frame (arms, legs, etc.)
Long bone
Found in arms and legs (femur, tibia, humourous)
Flat bones
As the name implies, they are flat (skull pelvis, thoracic cage (ribs, sternum))
Irregular bones
Include the bones of the vertebrae (temporal ethmoid Palatine)
Sesamoid bones
Small bones wrapped within tendons (patella, hallux Sesamoid, pisiform)
