sensory neurons
In the skin, neurons that detect stimuli are called mechanoreceptors for touch, nociceptors for pain, and thermoreceptors for temperature. In the eyes, neurons that detect light stimuli are called photoreceptors, specifically rods and cones located in the retina.
Eyes and ears, because the other three senses are not possible to detect a distance object.
Eyes detect light and visual information in the form of colors, shapes, and patterns. Light entering the eyes is focused by the lens onto the retina, where it triggers nerve impulses that are then processed by the brain to create the images we see.
No, vision is the process of detecting light with the eyes. Without light, there would be no stimuli for the eyes to detect, making it impossible to see.
The normal eye vision can detect a stimuli of over 120 degrees range vertically. It can also detect 160 degrees range horizontally.
sensory neurons
Ascaris, a genus of parasitic roundworms, do not have eyes. Instead of eyes, they have specialized sensory structures that help them detect changes in their environment. These structures allow them to sense light, chemicals, and other stimuli, which are important for their survival and behavior in their host organisms.
The distal ends of sensory neurons are called dendrites. Dendrites receive incoming signals or stimuli from the environment through sensory receptors, such as in the skin, eyes, ears, and other sensory organs. These signals are then transmitted to the cell body of the neuron and eventually to the central nervous system for processing.
The nerve cells connected in the eyes, nose, skin, and tongue are called sensory neurons. These specialized cells are responsible for detecting and transmitting sensory information from these organs to the brain for processing. Each type of sensory neuron is tuned to respond to specific types of stimuli, such as light (in the eyes), odors (in the nose), touch (in the skin), and taste (in the tongue).
Compound eyes detect motion, and simple eyes detect light. or The compound eyes are used to "see". The simple eyes are used to detect light intensity.
The simple eyes also called ocelli are only used to detect light intensity and not for seeing.
