What are nociceptors?
Pain receptors that are sensitive to harmful stimuli.
What are chemoreceptors?
Receptors that are sensitive to specific kinds of chemicals, such as those involved in smell and taste.
How does adaptation of sensory receptors work?
Adaptation refers to becoming less sensitive to a maintained stimulus over time.
What is the difference between slowly adapting and rapidly adapting receptors?
Slowly adapting receptors respond to sustained stimuli, while rapidly adapting receptors respond quickly to changes in stimuli.
What are mechanoreceptors?
Receptors that respond to mechanical changes, such as touch and pressure.
What are the two types of pain receptors?
A-delta fibers (fast pain) and C fibers (slow pain).
What is the significance of the dorsal root ganglia?
It contains the cell bodies of sensory neurons and is crucial for transmitting sensory information to the central nervous system.
What are photoreceptors?
Receptors that are sensitive to light and are found in the retina.
What is proprioception?
The sense of the position and movement of one's own body parts.
What are sensory receptors?
Specialized neurons that detect various stimuli in the environment and produce receptor potentials.
What is the role of receptor potentials?
They are generated by sensory receptors and allow the nervous system to understand environmental stimuli.
What is the pathway for tactile and proprioceptive information?
They travel through the spinal cord, reach the medulla, and then cross over to the opposite side before reaching the cerebral cortex.
What are thermoreceptors?
Receptors that are sensitive to temperature changes.
What is sensory transduction?
The conversion of one kind of energy to another, specifically physical stimulation to a neural signal.
What is a receptive field?
The specific area in which application of an adequate stimulus causes a receptor to respond.
What is the primary sensory cortex responsible for?
It is responsible for the conscious perception of sensory information.
