What happens at the level of the neuron starting with stimulus and ending with a response?
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
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 the minimum number of neurons required to carry information from a sensory receptor to the somatosensory cortex?
At least three neurons are required to carry information from a sensory receptor to the somatosensory cortex. The first neuron is located in the sensory receptor, the second neuron is in the spinal cord or brainstem, and the third neuron is in the thalamus before reaching the somatosensory cortex.
What occurs during the reflex arc.?
The pathway that an impulse travels from your foot back to your leg is an example of a reflex arc. A reflex arc includes a sensory receptor (in this case, a receptor in your toe), sensory neuron, motor neuron, and effector (leg muscle). Some reflex arcs include interneurons. In other reflex arcs, a sensory neuron communicates directly with a motor neuron.
What molecule is activated from the binding of an odorant to transmembranous receptor molecules on olfactory hairs?
The molecule activated from the binding of an odorant to transmembrane receptor molecules on olfactory hairs is called cyclic AMP (cAMP). When an odorant binds to the receptor, it triggers a signaling cascade that leads to the production of cAMP, which ultimately stimulates the olfactory sensory neuron and initiates the sense of smell.
What happens at the level of the neuron starting with stimulus and ending with a response?
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
What is the pathway of an impulse in a reflex arc?
Sensory receptor, sensory neuron, interneuron, motor neuron, and muscle.
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 another name for afferent neuron?
sensory neuron or receptor neuron.
What is the correct arrangement of a reflex arc?
Receptor → Sensory Neuron → Associative Neuron→ Motor division →Effectors
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.
What structure receives a stimulus from the external environment and relays it to the sensory neuron?
The receptor!
What is neurons associated with sensory receptor?
third order neuron
What are the five parts of a reflex arc?
Summarized below are the 5 major components of the reflex arc: 1. Receptor 2. Afferent (sensory) neurons 3. Association neuron 4. Efferent (motor) neurons 5. Effector
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 minimum number of neurons required to carry information from a sensory receptor to the somatosensory cortex?
At least three neurons are required to carry information from a sensory receptor to the somatosensory cortex. The first neuron is located in the sensory receptor, the second neuron is in the spinal cord or brainstem, and the third neuron is in the thalamus before reaching the somatosensory cortex.
What type of neuron begins a reflex arc?
A sensory receptor is the type of neuron that begins a reflex arc.
