Kinesiology 3330 Exam 1 Questions And Answers Solved.

Error Measures - correct answers Errors 1) Spatial accuracy Too far, too short 2) Temporal accuracy Too fast, too slow 3) Force Too much, too little Absolute error (accuracy) - correct answers -measure of how far away you are from the goal AE= trial score- criterion goal Constant Error (performance accuracy and bias) *Does Sign matter? What does this help determine? - correct answers -measure of how far away from the target and what direction -yes - determines too much force or too little force Variable Error - correct answers -measure of how consistent you were Total Error/Root Mean Square Error (RMSE) (skip) - correct answers ... Schmidts Schem theory consists of the following concepts: a) GMP b) coodinative structures c) motor response scheme d) successfully performing a skill requiring movements that have not been made in the same day e) A, C, D - correct answers E) A, C, D When toddler have to pick up a bottle with 2 hands, they are demonstrating: a) perception- action coping b) intrinsic coordinative structure c) order parameters d) none of the above - correct answers b) intrinsic coordinative structure What are the 2 types of coordinate structures? a) intrinsic coordinate structures and developed thru practice b) developed thru practice/sensory coordinate structure c) intrinsic/extrinsic coordinative structures d) none of the above - correct answers a) intrinsic coordinate structures and developed thru practice What would be an example of an order control parameter? a) learning a dance routine b) learning a play, then practicing in a game c) baby attempting to run then falls d) A & B e) All of the above - correct answers d) A & B What term would be characterized as preferred behavioral and energy efficient state? a) Stability b) Attractor c) control d) order - correct answers b) attractor When looking at GMP we can see this as a collection of: a) general motor program b) invariant features c)memory representation of class actions d) A & C e) All of the above - correct answers e) All of the above Is there feedback or no feedback in open loop system? - correct answers no feedback How many lobes of the brain? Name the lobes of the brain. - correct answers 4 lobes; frontal, parietal, occipital, temporal What is the function of the frontal lobe? - correct answers -responsible for the order in which we do things, reasoning, planning, parts of speech, movement, emotions, and problem solving Ex.The frontal lobe allows us to sequence and organize while performing activities. For example, the reason that we know that we should turn off the water after we shower has to do with the functions of the frontal lobe. What is the function of the parietal lobe? - correct answers -associated with movement, orientation, recognition, perception of stimuli Ex) touch, temperature, body position (proprioception), pain What is the is the function of the occipital lobe? - correct answers -associated with visual processing ex) When you see something light is coming into the eyes and signal are being sent to the brain (visual cortex) in the occipital lobe What is the function of the temporal lobe? - correct answers -involved in processing auditory signals Sensory neurons are also known as..... - correct answers afferent neurons What is the 3 parts of a neuron and describe each part? - correct answers 1)Cell body •Contains nucleus (keeps the cells alive) 2)Dendrites •Extensions from cell body -(one to thousands) •Receive information from other cells 3)Axon ("nerve fiber") •Extension from cell body - (one) •Sends information from neuron to neuron, glands, organs, muscles Name the 3 Types of Neurons - correct answers 1) Sensory neurons 2) Motor neurons 3) Interneurons What is the function of a sensory neuron? - correct answers -Also known as "afferent" neurons -Send information to CNS from sensory receptors -Unipolar - 1 axon; no dendrites -Cell body and most of the axon located in PNS; only axon central process enters CNS What is the function of a motor neuron? - correct answers Also known as "efferent" neurons -Two types influence voluntary movement: 1. Alpha motor neurons •Predominantly in spinal cord - axons synapse on skeletal muscles 2. Gamma motor neurons What is the function of interneurons? - correct answers - Specialized neurons that originate and terminate in the brain or spinal cord - Function as connections between: - Axons from the brain and synapse on motor neurons - Axons from sensory nerves and the spinal nerves ascending to the brain -What are the 2 components of the CNS? -The brain has 4 structural components most directly involved in the control of voluntary movement. What are they? - correct answers -Brain and spinal cord 1. Cerebrum 2. Diencephalon 3. Cerebellum 4. Brainstem
