Kinesthesis refers to sensory input that occurs within the body. Postural and movement information are communicated via sensory systems by tension and compression of muscles in the body.
A television system involves equipment located at the source of production, equipment located in the home of the viewer, and equipment used to convey the television signal from the producer to the viewer.
The purpose of all of this equipment, as stated… Visual cues to movement The eye is by far the most effective organ Kinesthesis refers to the sensing movement. Some animals are especially sensitive to visual stimuli that move in specific ways.
Generally the eyes of lower animals seem to respond selectively to what is of importance to survival. This is an economical arrangement since the animal tends to respond only to essential stimuli, the brain having little to do but relay signals to the motor system.
It is an inflexible mechanism, however; higher animals process visual information in more elaborate ways, the brain being more heavily involved. Features of human visual experience also suggest that movement detectors exist in the human brain.
Each retina in most higher animals has a central foveal zone for detailed colour and pattern vision and a surrounding peripheral zone that effectively is sensitive only to the grosser features of the outer visual field.
The peripheral retina is especially sensitive to movement often a signal of dangerwhich induces a reflex turning of the eyes to project the image on the fovea and permit the moving object to be recognized.

Visual stability Mechanisms have evolved that yield stable, clear visual input despite swaying and other blurring factors. In a reflex mechanism called optokinetic nystagmusthe eyes pursue a moving scene to keep the image stationary on the retina.
When they can move no farther, they snap back and pursue the scene again in a to-and-fro alternation of slow pursuit and quick return. These eye movements are readily observed in people who are looking at a moving pattern of stripes or turning their heads, this response being inhibited only when something stationary is visually fixated.
Similar nystagmic movements are triggered by impulses arising in the inner ear when the head moves. These persist even when the eyes are closed and may be felt by pressing the eyelids lightly as one rotates the whole body.
In a related stabilizing activity the eyes scan in quick jerks saccades with short fixations; e. Normally the eyes cannot move steadily over a stationary scene but make a series of stationary images like still photographs ; visual function tends to be suppressed when there is saccadic blurring.
Yet the eyes can follow a steadily moving object smoothly. When one looks from one point to another, movements of the retinal image are the same as those produced by a moving scene on a stationary eye.
It might be thought that the sensory structures found in the eye muscles would provide the cues for judging whether it is the eye or the scene that has moved. Yet we see the scene as stationary only when we move our eyes voluntarily and not when they are moved passively by the finger.
This suggests that motor-nerve signals inform us whether our eyes are moving, rather than the sensory structures in the eye muscles.
When the eye is moved by pushing it with the finger there is no normal motor discharge to inform the brain, and changes in retinal image are perceived as movement of the scene. Indeed, people with paralyzed eye muscles experience the scene as moving when they try to move their eyes.
When the motor discharge thus generated is not accompanied by the expected image motion, the person falsely perceives the scene and the eye to be moving together. Relative visual movement A visual field containing familiar objects provides a stable framework against which relative motion may be judged.
People often report that an isolated point of light in a dark room is moving when it is not; the experience is known as autokinetic movement.Kinesthesis refers to the A) process of organizing and interpreting sensory information. B) diminished sensitivity to an unchanging stimulus.
C) quivering eye movements that enable the retina to detect continuous stimulation. the process of organizing and interpreting sensory information.
C) increasing perception of a constant, annoying. The book addresses balance in standing and sitting, how to use arms to prevent injury, free and supported breathing, anatomical information about how the body works, training the kinesthetic sense, importance of movement for musicians and practical exercises for students and teachers.
"Kinesthesis refers to sensory input that occurs within the body." Proprioceptors are nerves which are located in your joints, tendons, and muscles that are working with the brain to let a person.
May 27, · The etymological meaning of the word as used in physiology refers specifically to the motion of the body, and a distinction between kinesthesia and the sense of the position of the body is sometimes made in technical texts.
In popular use the distinction is made less often. n. The sense that detects bodily position, weight, or movement of the muscles, tendons, and joints.
The sensation of moving in space. Other articles where Kinesthesis is discussed: human sensory reception: Kinesthetic (motion) sense: Even with the eyes closed, one is aware of the positions of his legs and arms and can perceive the movement of a limb and its direction.
