"Sensory neurons, also known as afferent neurons..."
Sensory receptors are specialized structures that respond to stimuli such as light, sound, or touch and convert them into signals that can be processed by the nervous system.
Sensory modalities: The different types of sensory inputs our body receives, such as touch, taste, smell, sight, and hearing.
Sensory transduction: The process where sensory information is converted into neural signals that can be sent to the brain for processing.
Receptor cells: Specialized cells that are responsible for detecting specific sensory stimuli and initiating sensory transduction.
Sensory adaptation: The process where the sensitivity of our sensory receptors adapts to changes in the environment.
Sensation: The process of detecting sensory stimuli and encoding them into neural signals.
Perception: The process of interpreting sensory signals to make sense of the world around us.
Vision: The process of receiving and interpreting visual information, including how the eye works and visual processing in the brain.
Hearing: The process of receiving and interpreting auditory information, including how the ear works and auditory processing in the brain.
Taste: The process of receiving and interpreting taste information, including how taste receptors work and how different taste sensations combine.
Smell: The process of receiving and interpreting smell information, including how olfactory receptors work and the relationship between smell and memory.
Touch: The process of receiving and interpreting tactile information, including how touch receptors work and the role of touch in communication and emotion.
Synesthesia: A neurological condition where the stimulation of one sensory modality leads to the experience of another sensory modality.
Sensory integration: The process of combining sensory information from different modalities to form a coherent perception of the environment.
Mechanoreceptors (touch): Mechanoreceptors are sensory receptors that detect mechanical pressure and touch stimuli, allowing us to perceive physical sensations and textures.
Thermoreceptors (temperature): Thermoreceptors are sensory receptors that detect and respond to changes in temperature, allowing individuals to perceive heat and cold stimuli.
Nociceptors (pain): Nociceptors, often referred to as pain receptors, are sensory nerve endings that detect and transmit signals of potentially harmful stimuli, allowing the brain to perceive and localize pain.
Photoreceptors (sight): Photoreceptors are sensory cells located in the eyes that detect and transform light into neural signals, enabling vision.
Chemoreceptors (smell and taste): Chemoreceptors are sensory receptors responsible for perceiving and distinguishing smells and tastes in the environment.
Hair cells (hearing): Hair cells are specialized sensory receptors in the ear responsible for converting sound vibrations into electrical signals.
Cutaneous receptors (skin senses): Cutaneous receptors, also known as skin senses, are sensory receptors located in the skin that detect various stimuli such as touch, temperature, pain, and pressure.
Proprioceptors (body position): Proprioceptors are sensory receptors that provide information about the position and movement of our body parts.
Baroreceptors (blood pressure): Baroreceptors are sensory receptors located in the walls of blood vessels and the heart that detect changes in blood pressure and initiate responses to maintain homeostasis.
Osmoreceptors (body fluids): Osmoreceptors in the context of Psychology and Sensory Receptors are specialized cells that detect changes in the concentration of body fluids to regulate water balance and maintain internal homeostasis.
Stretch receptors (mechanical pressure): Stretch receptors (mechanical pressure) are sensory receptors that detect changes in muscle length and provide information about the stretching or compression of tissues.
Pacinian corpuscles (vibration): Pacinian corpuscles are sensory receptors found in the skin that detect vibration and pressure.
Golgi tendon organs (tension): Golgi tendon organs are sensory receptors located in tendons that detect changes in muscle tension and provide important information for proprioception and muscle control.
Muscle spindles (stretch and length): Muscle spindles are specialized sensory receptors found within skeletal muscles that detect changes in muscle stretch and length.
Joint receptors (movement and position): Joint receptors refer to specialized sensory receptors located in the joints that provide information about movement and position of body parts.
"...convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials."
"This process is called sensory transduction."
"The cell bodies of the sensory neurons are located in the dorsal ganglia of the spinal cord."
"The sensory information travels on the afferent nerve fibers in a sensory nerve, to the brain via the spinal cord."
"Spinal nerves transmit external sensations via sensory nerves to the brain through the spinal cord."
"The stimulus can come from exteroreceptors outside the body, for example those that detect light and sound."
"...or from interoreceptors inside the body, for example, those that are responsive to blood pressure or the sense of body position."
