The intersection between a neuron and another neuron, a muscle, a gland, or a sensory receptor is called a synapse. At this junction, the transmitting neuron releases neurotransmitters that bind to receptors on the receiving cell, which can be another neuron, a muscle cell (causing contraction), a gland (triggering secretion), or a sensory receptor (initiating sensory processing). This communication is crucial for nervous system function, allowing for the integration of signals and responses throughout the body.
The first order sensory neuron can sometimes be a sensory receptor because it is what sends the signal to the brain from the receptor. The second order goes from the brainstem to the thalamus.
sensory receptor
A sensory receptor is specialized nerve ending that responds to specific stimuli, such as light, sound, or pressure. The point at which the stimulus intensity is sufficient for the receptor to generate a detectable signal is known as the threshold. Once this threshold is surpassed, the sensory receptor can transmit information to the nervous system, enabling perception of the stimulus.
Receptor potentials are graded changes in the membrane potential of sensory receptors in response to stimuli. When a receptor potential is generated, it can lead to the generation of action potentials in sensory neurons if the depolarization reaches a certain threshold. This conversion of receptor potential to action potentials allows the nervous system to transmit sensory information to the brain for processing and perception. Ultimately, receptor potentials play a crucial role in the sensory transduction process, enabling the body to respond to environmental changes.
No, a reflex arc begins with a receptor that detects a stimulus and sends a signal through a sensory nerve to the central nervous system.

Photoreceptor
Eyes: The sensory receptor in the eyes is the photoreceptor cell, specifically the rods and cones, which detect light and color. Nose: The sensory receptor in the nose is the olfactory receptor, located in the olfactory epithelium, which detects odor molecules. Tongue: The sensory receptors in the tongue are taste buds, which contain taste receptor cells that detect different tastes like sweet, salty, bitter, sour, and umami. Skin: The sensory receptors in the skin include mechanoreceptors (detect touch and pressure), thermoreceptors (detect temperature), nociceptors (detect pain), and proprioceptors (detect body position and movement).
Sensory receptors translate physical energy into neural signals.
Nerve receptor is a specialized cell or nerve endings that respond to sensory stimuli.
Sensory receptor located at the distal end of a neuron or an associated sensory structure. When stimulated it creates a receptor potential, when that reaches its threshold, it will trigger 1 or more nerve impulses in the sensory neuron.
