What type of sensory receptor helps humans detect light?
Photoreceptors detect light during vision. More specific examples of sensory receptors are baroreceptors, propioceptors, hygroreceptors, and osmoreceptors.
Which type of neuron detect stimuli and transmit signals to the brain and the spinal cord?
Afferent neurons are sensory nerves These are sensory neurons carrying nerve impulses from sensory stimuli toward the central nervous system and brain. Afferent neurons carry signals to the brain and spinal cord as sensory data.
Why does a reflex arc result in a very quick response *?
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
Which type of neuron relays signals from the central nervous system to the muscles?
Motor neurons have a long axon and short dendrites and transmit messages from the central nervous system to the muscles (or to glands).
What are the 6 sensory receptors?
Sensory receptors are primarily classified as chemoreceptors, thermoreceptors, mechanoreceptors, or photoreceptors….Adequate Stimulus.
| Sensory receptors with corresponding stimuli to which they respond. | |
|---|---|
| Receptor | Stimulus |
| Photoreceptors | Visible light |
| Proprioceptors | Sense of position |
| Thermoreceptors | Temperature |
Which body locations typically lack Proprioceptors?
Which body locations typically lack proprioceptors? The skin surface does not contain proprioceptors.
What is the correct path of reflex arc?
The correct pathway of reflex arc is : Sensory stimulus → Dentrite of sensory neuron → Axon of sensory neuron → CNS → Dendrite of motor neuron → Axon of motor neuron → Effector organ.
Which is the correct order of events in a reflex arc?
Stimulus, sensory neuron, intermediary neuron, motor neuron and defector organ is the correct order of general reflex arc.
Which type of neuron is the fastest?
myelinated neuron
The type of neuron that conducts the fastest is a myelinated neuron. These neurons are insulated by sheets of lipids called myelin.
