Sensory Components of Motor Control

Question 1

Answer 1

Dorsal Stream

Question 2

Sensitive to muscle tension, regulate the level of force produced in the muscle, and more active when the muscle is producing force.

Answer 2

Golgi Tendon Organs

Question 3

Responsible for signaling active, touch, temperature, pressure, and movement.

Answer 3

Tactile - Cutaneous Receptors

Question 4

Answer 4

Primary Visual Cortex

Question 5

Aids object manipulation, movement, accuracy, consistency, force adjustments, timing, and distance estimation.

Answer 5

Tactile information in motor control

Question 6

Answer 6

Posterior Parietal Cortex

Question 7

Responsible for capturing changes in muscle length
Most active when the muscle is STRETCHED.

Answer 7

Muscle Spindles

Question 8

Provides information about the state of the ENVIRONMENT in which one’s body exist. Vision, Audition, and Touch

Answer 8

Exteroception

Question 9

Provides information about the body itself:
Vestibular apparatus
Muscle Spindles
Golgi Tendon Organs

Answer 9

Proprioception

Question 10

Responsible for capturing changes in head position and movement
Crucial for maintaining posture and balance
Semi-circular Canals

Answer 10

Vestibular Apparatus

Question 11

“WHAT” pathway

Answer 11

Ventral stream

Question 12

“WHY” pathway

Answer 12

Dorsal stream

Question 13

Answer 13

Inferior Parietal Cortex

Question 14

Answer 14

Ventral Stream

Question 15

Conscious identification of objects
Sensitive only to events in the CENTER of the visual field
Severely degraded by dim lighting conditions

Answer 15

“What” Ventral Stream

Question 16

Allows the smooth perception of movement
Involves the entire visual field
Spatial localization and object manipulation
Operates unconsciously - size and orientation

Answer 16

“Where” Dorsal stream
