These structures dictate the permissible motions of the knee.
What is the articular surfaces of the tibia and femur
100
A homogeneous representation of a rigid body in space.
What is a pose?
100
These joints, characterized by a fluid capsule, hyaline cartilage are the most prevalent joint in the human body
What are synovial joints?
100
In Euler's theorem, there are this many distinct sequences of rotation.
What is twelve?
100
Basically.
What is Prof. Kaupp's most overused phrase?
200
These 'ropes' form part of the passive control elements of the knee.
What are the ligaments?
200
How many independent parameters do we need to define an object in space?
What are three?
200
This force is transmitted in both synarthrosis and diarthrosis joints
What is compression?
200
The classical theory, presented by Euler, was based upon a nested gimbal. His theory holds that a sequence of rotations is either a gimbal hierarchy, or this.
What is a temporal order of rotations?
200
During weightlifting, a person typically starts in a position of low __X___ for high __Y___ and ends in a position of high ___X___ for low ___Y___
What is congruence and maneuverability?
300
These structures of the knee help to stabilize and increase conformity of the joint during motion
What are the mensicii?
300
These are the three required elements for defining the position and orientation of a rigid body in space.
What is a global reference frame, a local reference frame and the position of one with respect to the other?
300
This type of joint is primarily held in place by muscular forces and constraints.
What is a force-closed joint?
300
Decomposition of an Euler matrix, relates specific elements of the Euler rotation matrix to this, in order to find the specific angles between axes.
What is the rotation matrix, or direction cosine matrix?
300
These entities are the cosines of the angles between the vector and the three coordinate axes.
What are direction cosines?
400
The muscles in this group contribute to ensuring proper tracking of the patella.
What is is extensor group?
400
These are the two types of problems when using homogeneous transfomrations
What are alias and alibi problems?
400
This characteristic describes the amount of redundancy of a series of segments and joints.
What is maneuverability?
400
This is the name of the principle that explains why an ZYX Euler sequence isn't the same as a YZX.
What is non-commutative?
400
In your labs, measurements of joint angles during motion analysis are subject to error caused by this, described as one joint rotation (e. g., flexion) being interpreted as another (e.g., abduction).
What is crosstalk?
500
These are the major biochemical components of articular cartilage.
What are proteoglycans, collagen and water?
500
This type of homogeneous transformation converts global coordinates from a starting position to global coordinates at a final position.
What is a global displacement or transformation?
500
1. Articular surfaces
2. Ligaments
3. Muscular forces
4. Motor control
5. Contact area
What is imposed constraints of joint motion?
500
This is a primary reason as to why Euler angles are more prone to error in nominal joints than ideal ones.
What is orthogonality?
500
Mechanism and magnitude dictate this phenomena, which epidemiology illustrates occurs most often in youth.
