Question
1. Describe the sensory receptors located in the skin that provide tactile sensory information related to movement. 2. Discuss three movement-related characteristics influenced by tactile sensory information; indicate how we know each of them is influenced by tactile sensory information. 3. Describe three types of proprioceptors, where each is located, and the type of movement information each provides 4. Discuss three methods researchers have used to investigate the role of proprioception in motor control and what the results of that research have told us about two roles of proprioception in the control of movement. 5. Describe the anatomical pathway the image of an object would take through the eye and visual neural system.Explanation / Answer
1.Mechanoreceptors - when we touch we activate CNS with information related to pain , temperature, stretch and movement.
Greatest information in the finger tips.
2.Movement accuracy-decreases when tactile information is not available.
Movement consistency- without tactile sensory feedback movement trial from one to another is also decreased.
Movement force adjustments- depends on tactile feedback .
3.propiocetors are sensory neurons located in muscle, tendon , ligament and joints which picks up the information of position and sense of joints.
muscle spindles- located in skeletal muscle for length of muscle fibers.
golgy tendon body - in the muscle fibers towards the tendon to detect muscle tension and force.
joint receptors- located in the joints for intense movement and position
5.anatomical pathway of image and object
the neural signs are initiated by the retina via axons of ganglion through optic nerves and crosses at optic chiasma and then tovtge lateral geniculate body to the primary visual cortex
