What is the neural pathway of a single reflex called?
The neural pathway of a single reflex is called a reflex arc. It involves the sensory neuron carrying information from the receptor to the spinal cord, where it synapses with a motor neuron that carries the response signal to the effector muscle or organ. This simple pathway allows for rapid, involuntary responses to stimuli.
Where on the olfactory receptor does the odourant bind?
Odorants bind to specific sites on the olfactory receptors, which are located on the cilia of olfactory sensory neurons in the nasal epithelium. Each olfactory receptor protein has a unique binding site that interacts with certain molecular features of the odorant, triggering a signal transduction pathway. This binding activates the receptor, leading to the generation of neural signals that are sent to the brain for odor perception.
What is the receptor in the pupillary light reflex arc?
The receptor in the pupillary light reflex arc is the retinal photoreceptors, specifically the rods and cones in the retina. These photoreceptors detect light and convert it into neural signals, which are then transmitted via the optic nerve to the brain. The signals are processed in the pretectal nucleus, leading to coordinated constriction of the pupils in response to light stimulus.
What substances has a chemical composition similar enough to dopamine to allow it to fit dopamine receptor sites in the brain?
Substances like norepinephrine, epinephrine, and serotonin have chemical compositions similar enough to dopamine to interact with dopamine receptor sites in the brain. These substances can bind to dopamine receptors and exert similar effects on neural signaling pathways.
Which receives signals a fluid mosaic model or a receptor?
a receptor
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.

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.

It involves the sensory neuron carrying information from the receptor to the spinal cord, where it synapses with a motor neuron that carries the response signal to the effector muscle or organ. This simple pathway allows for rapid, involuntary responses to stimuli.
How are neural impulses generated?
Neural impulses are generated when a neuron receives signals from other neurons or sensory receptors, causing a change in its membrane potential. This change in membrane potential triggers an action potential, a rapid electrical signal that travels down the axon of the neuron. This action potential then triggers the release of neurotransmitters at the synapse, allowing the signal to be passed on to other neurons.
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.
Before an olfactory receptor can detect an odorant it has to?
Before an olfactory receptor can detect an odorant, it needs to bind to a specific odorant molecule. This binding triggers a series of biochemical reactions that generate neural signals, which are then sent to the brain for interpretation.
The sensory receptor sensory neuron motor neuron and effector involved in a reflex form a?
The sensory receptor, sensory neuron, motor neuron, and effector involved in a reflex form a reflex arc. This is a neural pathway that controls a reflex action in response to a stimulus without conscious thought.

Can gastritis be cured?
Simple gastritis can be cured by a course of PPI e.g. omeprazole or H2 receptor antagonists e.g. ranitidine.
