Which of the following are correct names for the tube that connects the middle ear to the nasopharynx? Bulbous corpuscles are also known as Ruffini corpuscles, or type II cutaneous mechanoreceptors. Merkels disks are densely distributed in the fingertips and lips. the general sense of touch, which is known as somatosensation, can be separated into light pressure, deep pressure, vibration, itch, pain, temperature, or hair . Mechanoreceptors sense stimuli due to physical deformation of their plasma membranes. Bulbous corpuscles are also present in joint capsules, where they measure stretch in the components of the skeletal system within the joint. The somatosensory is the system of nerve cells that responds to changes to the external or internal state of the body. 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. Trans-retinal is reconverted to cis-retinal -Lens Posterior one-third of the tongue and the superior pharynx - Glossopharyngeal nerve (CN IX) Ruffini endings also detect warmth. Meissners corpuscles extend into the lower dermis. *Stapes A free nerve ending, as its name implies, is an unencapsulated dendrite of a sensory neuron.
