A receptor (protein) on a neuron that receives stimulus (light, pressure, chemical...etc). The stimulus generates a receptor potential (local disturbance/slight depolarization in membrane potential).

Where can you see adaptation of the nerve cells in the simple sensory receptor?
in the liver
The three primary levels of neural integration in a somatosensory system?
-Level I: The receptor level corresponding to the sensory receptors -Level II: The circuit level corresponding to the ascending pathways -Level III: The perceptual level corresponding to the awareness of the incoming stimuli
What is the advantage of having multiple receptor subtypes for a neurotransmitter?
Multiple receptor subtypes allow for more "fine-tuned" neuromodulation of a given "signal" in a neural network. Each receptor subtype typically has a different binding affinity for the given neurotransmitter. Therefore, the neurotransmitter may bind more strongly or more weakly to one subtype over another. This is most likely an effect of genetic variation, as the genes coding for the protein(s) present in the receptor slightly vary from subtype to subtype, yet still allow for binding by the neurotransmitter ligand.
Which receives signals a fluid mosaic model or a receptor?
a receptor
What is the most simple nervous system pathway?
The reflex arc is the simplest neural circuit.
How are neural impulses generated?
The neural impulse is the electrical charge that goes from the nerve receptor to the brain. They are generated when the nerve receptor detects a foreign stimuli.
The receptor cells that convert light energy into neural signals are called?
The receptor cells that convert light energy into neural signals are called photoreceptor cells. These cells are located in the retina of the eye and are responsible for producing electrical signals in response to light stimulation.
Functions of sensory receptor?
Sensory receptors translate physical energy into neural signals.
What is the role of the receptor?
The main role of the NMDA receptor in the body is in ensuring neural plasticity. Further research is on-going to further refine understanding of this receptor, and this conclusion may change in future as more studies may find further roles for this receptor.

What are you doing when you use your 5 senses?
A sensory receptor in that part of the body sends an electrical signal via a neural pathway to the appropriate processing region of the brain.
The process of changing physical stimulus to neural stimulus is called what?
Transduction is the process of changing physical stimulus to natural stimulus. This causes receptor cells to produce an electrical change in response.
The three primary levels of neural integration in a somatosensory system?
-Level I: The receptor level corresponding to the sensory receptors -Level II: The circuit level corresponding to the ascending pathways -Level III: The perceptual level corresponding to the awareness of the incoming stimuli
What two type of cell populations make up neural tissue?
Sensory (receptor), motor (effector), and intermediate (relay) nuerones. They have functions of transmitting impulses to nerve cells, from nerve cells to effector muscles, and from one nerve cell to another respectively.
What are important tissue receptor tumor markers?
estrogen receptor, progesterone receptor, interleukin-2 receptor, and epidermal growth factor receptor.
