Cis-retinal is transformed to trans-retinal d. photoreceptor. Merkels disks are densely distributed in the fingertips and lips. If strong enough, the graded potential causes the sensory neuron to produce an action potential that is relayed into the central nervous system (CNS), where it is integrated with other sensory informationand sometimes higher cognitive functionsto become a conscious perception of that stimulus. In the eye, the __________ humor is gelatinous. Opaque: What do Merkel cells detect? The __________ ligaments connect the ciliary body to the lense. In proprioception, proprioceptive and kinesthetic signals travel through myelinated afferent neurons running from the spinal cord to the medulla.
