Joints, Ligaments and Vessels Flashcards
An example of a uniaxial joint is
knee
An example of a multiaxial joint is
hip
A ligament
attaches bone to bone
Which of the following statements are NOT true about skeletal muscle:
Involuntary movements
Isometric
contraction
A contraction of muscle in which no noticeable shortening of
the muscle took place.
How many different types of muscle are there?
3
Ipsilateral
On the same side of the body, or limb
Which of the following statements are NOT true about articular cartilidge
Has its own nerve supply
How many different types of synovial joint are there?
4
How many different types of blood vessels are there?
5
Ligament
A dense regularly arranged connective tissue that attaches
bone to bone
Medial
The side or aspect nearest the midline of the body
Median
Situated or placed in the middle of the body
Mid Stance Event
The point at which the body passes directly over the
supporting limb in normal walking.
Mid Stance Period
The part of the stance phase which starts with toe off of the
opposite foot and ends when the body is directly over the
supporting limb (mid stance event). This makes up the first
half of the single support phase
Mid Swing Event
The point where the reference extremity passes directly
below the body
Mid Swing Period
The portion of the swing phase from maximum knee flexion of
the reference extremity to a tibial vertical position.
Moment
The rotational potential of the forces acting on a joint, also
called torque.
Moment Arm
The perpendicular distance from the action of a force to the
axis of rotation.
Momentum
The tendency to remain in motion unless an opposing force is
applied. Mass times velocity.
Observational Gait
Analysis
Visual definition of an individual’s limb and trunk motions during
walking.
Open Kinetic Chain
or Open Chain
The state of non-weightbearing. Observed during the swing
phase of the gait cycle.
Origin
A place of attachment of muscle to a more stationary bone,
the end opposite the insertion.
Joint Forces
Forces that act on articular surfaces and are due to muscular
action, gravity and inertia
Kinematics
The branch of dynamics that deals with motion but excludes
the consideration of mass and force.
