Kin 100 Exam 2
The motor cortex consists of two lateral lobes and a central lobe. It serves to coordinate complex voluntary movements, posture, and balance
False
In the stretch reflex, which muscle is inhibited?
Antagonist
Bowling would be an example of what type of movement?
Closed movement
What stage of learning has the highest amount of error that might not be identified by the individual?
Cognitive stage
A compression force is when a material is stretched apart
False
A runner is most efficient when their Center of Gravity has a large vertical displacement while they run
False
All of the learning curves discussed in class measure learning and not performance
False
An example of a Kinematic measurement would be the speed (MPH) a car travels
False
Creeping is when the infant pulls him/herself along with the stomach on the floor
False
Depth perception is measured with an eye chart and can be defined as the sharpness of vision
False
Reactions time decrease as we age from 40-80
False
Riding a mountain bike through the woods would be an example of a closed movement
False
Supination should take place during the heel strike of the Gait Cycle
False
The Center of Mass (COM) is ALWAYS located within a body
False
When learning a new activity everyone learns at the same rate and has similar learning curves
False
When you are learning a new skill there is usually little to no errors in practice
False
Your knees should not go over your toes when you squat
False
The muscle group that is best able to protect the anterior cruciate ligament (ACL) from injury is
Hamstrings
What is the correct order for the information processing model?
Input, decision making, output, feedback
Which of the following terms is the study of motor performance throughout the life span from birth through old age?
Motor development
Which of the following sensory receptors are located within the muscle?
Muscle spindles
What part of the nervous system contains sensory nerves and receptors?
Peripheral nervous system (PNS)
A normal Q angle is between 18-22 degrees
True
A slap shot in hockey would be an example of a discrete movement
True
Collateral ligaments (MCL & LCL) protect the knee joint from medial and lateral movements
True
Force can be described as a push or a pull against a body/object
True
If you can easily multi task and change the radio station while you re driving, it is assumed you would be in the autonomic stage of learning
True
In the Load Deformation Curve if the velocity is increased then less force is required to reach the yield point at failure point
True
In the Load-Deformation Curve the point at which the material breaks is known as the failure point
True
In the stretch reflex, when the doctor taps your patella with a hammer the quadriceps muscle group is the agonist
True
Increasing the contact surface will reduce the stress of an object by distributing force
True
Kinematics is concerned with the description of movement
True
Motor development is the study of movement behavior and the underlying processes across the lifespan
True
One function of pronation during the Gait Cycle is to absorb shock during the heel strike
True
One function of the Ski boot to transfer forces from the ankle to the large joints and muscle groups of the body
True
The Cerebellum fine-tunes body movements and motor skills using information derived from the sensory neurons
True
The Q angle describes the angle between the thigh bone and an imaginary line extending straight up the patella
True
The function of the ACL is to prevent the tibia from sliding forward
True
The heel strike during walking is part of the Stance Prince
True
When increasing stability to a running shoe manufacturers are increasing the stiffness and reducing the cushioning
True
