Eyes and ears, because the other three senses are not possible to detect a distance object.

Directional stimuli are environmental stimuli, particularly light and sound, that the direction of which it comes and the direction of the response to the stimulus are of upmost importance. Non-directional stimuli are those where receptors do not detect the direction from which they come. Chemical stimuli are usually not directional.
The Lens are very flexible, thus they can focus on light from nearby & distant objects. Also, photoreceptors receive light and convert it into electrical signals. Cones/Rods then detect small changes from far away.
Meissner's corpuscles
No, not directly. Some sensory neurons can detect the effect of a motor neuron firing.

Sensory (afferent) neurons
They are nerves. These nerves tell us exactly what we feel, and then send that information to the brain.
they are called receptors.
Auditory sensory neurons are specialized to detect stimuli from the environment which triggers the neuron to transmit a message to the central nervous system. These stimuli are both voluntary and involuntary.

Sensory Neurons- they detect stimuli and transmit signals to the brain and the spinal cord, which are both made up of interneurons
