Coating that provides nutrients to eye. The general senses can be divided into somatosensation, which is commonly considered touch, but includes tactile, pressure, vibration, temperature, and pain perception.
The pain and temperature receptors in the dermis of the skin are examples of neurons that have free nerve endings. Which of the following statements is correct Select one a A constructor used to.

The base of the stapes covers the oval window which allows sound waves to pass from the tympanic membrane, into the cochlea of the inner ear. Light touch is transduced by the encapsulated endings known as tactile (Meissner's) corpuscles. An individual sensory modality represents the sensation of a specific type of stimulus.
An interoceptor is one that detects stimuli from internal organs and tissues, such as the receptors that sense the increase in blood pressure in the aorta or carotid sinus.
