When a person abducts the shoulder to 90 degrees, then moves the arm backward, what is that motion called?
Horizontal abduction
The fibula is on which side of the lower leg?
Lateral
What kind of movement is closed chain and what does it promote?
Functional movement and provides stability
(proximal joints moving in relation to fixed distal segment)
What kind of movement is open chain and what does it promote?
Free movement and promotes mobility
(Allows joints to move together or independently of others
What is defined as force?
Any push or pull of matter
What is tensile force?
pulling
What is compressive force?
pushing
What is defined as a first class lever in the body?
Exerted force and resistive force
on opposite sides of axis
(Seesaw motion=human neck)
What is defined as a second- class lever in the body
Resistive force closer to
axis than exerted force
and on same side
(examples are using the wheelbarrow, and the ankle)
What is defined as a third- class lever?
Most common in human body
Allows for higher-velocity
movements
(shoveling is an example)
What is joint reaction force?
Force generated within the joint in
response to external forces acting
upon it
What is stress?
Amount of applied force per area
What is strain?
Amount of material displacement under
specific amount of stress
What is elasticity?
The ability to stretch and return to the
original shape
What is elastic deformation?
Ability to return to normal shape after strain
What is yield point?
Maximum stress that can be sustained before tissue failure
What is Plastic deformation?
*Sprain
*Permanent deformation of tissue but retains continuity
What are Biomechanics?
Examines the structure, function, and motion of the biological systems that make up a living organism
What are the biomechanics of the bone?
Made of calcium and collagen
What is cortical bone?
*Greater mineral content than collagen
*Shaft of long bones
*Rigid support
