A more developed two-point tactile discrimination :-a- indicates a greater threshold distance for feeling of two points of touch applied simultaneously b- is seen in the proximal regions of the body compared with the distal regionsc- is inversely related to the size of the receptive fields of the stimulated sensory unitsd- depends upon the type of the involved touch receptor

how does visual transduction occur in rods? Select one: a. By inhibition: light bleaches the rhodopsin molecules, which closes sodium channels. This hyperpolarizes the rods and increases GABA release. b. By excitation: light inhibits rhodopsin molecules, which blocks sodium ion influx. This depolarizes the rods and causes glutamate release. c. By inhibition: light bleaches rhodopsin molecules, which closes sodium channels. This hyperpolarizes the rods and reduces glutamate release. d. By excitation: light activates rhodopsin molecules, which opens sodium channels. This depolarizes the rods and causes glutamate release

Identify, in correct order, of sensation to perception, the major connections of the pathway underlying fine touch, and pressure.   afferent axons decussate at medulla    primary somatosensory cortex activated somatosensory humunculus according to where on body touch was felt   free nerve endings depolarize dendrites of peripheral afferents   axons in the medial lemniscus terminate in the ventral posterior nucleus of the thalamus   axons of afferents enter into dorsal horn of spinal cord and ascend ipsilaterally

How does the size of various parts of the primary somatosensory cortex relate to touch sensitivity and to receptive field size?

What are the functions of the sensorimotor system vision? Please include references.

Which two types of receptors would you expect to find in "tubes" inside your body — namely, blood vessels and the respiratory, digestive, + urinary tracts? Group of answer choices Thermoreceptors Nociceptors Proprioceptors Chemoreceptors Tactile receptors Baroreceptors

The list below classifies sensory receptors by the stimulus that activates them. Using your textbook or other resource, name the receptor for each stimulus type. activated by touch, pressure, vibration, and stretch. activated by changes in temperature activated by light or changes in light wavelengths activated by changes in chemical concentrations in a solution activated by tissue injury or situations that may lead to tissue injury

Table to compare the different types of sensory receptors and to predict the results of damage of each. Please I need a surely answer and a quicker response

Put the following in the correct order of the most direct visual processing pathway from eyes to brain. 1. Lateral geniculate neuron 2. Ganglion cell 3. Visual cortex neuron 4. Bipolar cell 5. Optic nerve 6. Photoreceptor

Retinal ganglion cells fire at a variety of rates depending on characteristics of the visual stimulus. Select one: True False
