Can a first order sensory neuron sometimes be a sensory receptor?
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.

The point where a stimulus is great enough to be sensed is a 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.
What does receptor potentials cause?
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.
Does A reflex arc begins with a receptor at the end of a sensory nerve?
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.
What is the sensory receptor in the eyes What is the sensory receptor in the nose What is the sensory receptors in the tongue What is the sensory receptors in the skin?
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).
What are the sensory receptors for eyes and nose?
The sensory receptors for the eyes are the optic nerve and the retina. The sensory receptor for the nose are the olfactory nerves.
Is the sensory receptor the first element in the sensory pathway?
Yes the sensory receptor is the first element.
Can a first order sensory neuron sometimes be a sensory receptor?
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.
What is an organ that contains receptor cells called?
An organ that contains receptor cells is called a sensory organ. These organs perceive external stimuli such as light, sound, touch, taste, and smell and transmit this information to the brain for processing.
What structure receives a stimulus from the external environment and relays it to the sensory neuron?
The receptor!
Which sensory receptor is responsive to light?
Photoreceptor
Is a control mechanism that intensifies an earlier reaction A sensory receptor An effector Negative feedback Positive feedback?
sensory receptor
Functions of sensory receptor?
Sensory receptors translate physical energy into neural signals.
What is a receptor nerve?
Nerve receptor is a specialized cell or nerve endings that respond to sensory stimuli.
What is the receptor of a reflex arc?
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.
What is the pathway of an impulse in a reflex arc?
Sensory receptor, sensory neuron, interneuron, motor neuron, and muscle.
