What is the pathway from stimulus to response?
Overview of the Stimulus-Response Pathway Sensory neurons transmit information from sensory receptors to the central nervous system (CNS) Relay neurons (interneurons) transmit information within the CNS as part of the decision-making process.
How a nerve impulse travels from stimulus to response?
Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon. A nerve impulse travels along the neuron in the form of electrical and chemical signals. The axon tip ends at a synapse. A synapse is the junction between each axon tip and the next structure.
How do neurons respond to stimuli?
Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells). The nucleus of a neuron is located in the cell body. Extending out from the cell body are processes called dendrites and axons.
What type of stimulus does nerve tissue respond to?
Nervous-system response When a neuron is stimulated by an excitatory impulse, neuronal dendrites are bound by neurotransmitters which cause the cell to become permeable to a specific type of ion; the type of neurotransmitter determines to which ion the neurotransmitter will become permeable.
What is the stimulus and what is the response?
A change in the environment is the stimulus; the reaction of the organism to it is the response.
What are some examples of stimulus and response?
Examples of stimuli and their responses:
- You are hungry so you eat some food.
- A rabbit gets scared so it runs away.
- You are cold so you put on a jacket.
- A dog is hot so lies in the shade.
- It starts raining so you take out an umbrella.
What is a stimulus and a response?
How to describe the pathway of a nerve impulse?
The pathway is as follows: Stimulus -> Sensory Receptor -> Sensory Neuron -> Spinal Cord -> Brain -> Spinal Cord -> Sensory Neuron -> Neuromuscular Junction -> Skeletal Muscle Start your 48-hour free trial and unlock all the summaries, Q&A, and analyses you need to get better grades now.
How are neurons involved in the stimulus response pathway?
Overview of the Stimulus-Response Pathway Three types of neurons are required to transmit information via the stimulus-response pathway: Sensory neurons transmit information from sensory receptors to the central nervous system (CNS) Relay neurons (interneurons) transmit information within the CNS as part of the decision-making process
Where does the signal go after leaving the nerve?
The signal leaves the nerve and spreads around the muscle, causing contraction or expansion. The pathway is as follows: Stimulus -> Sensory Receptor -> Sensory Neuron -> Spinal Cord -> Brain -> Spinal Cord -> Sensory Neuron -> Neuromuscular Junction -> Skeletal Muscle
How does pressure on receptors affect nerve impulses?
Pressure on receptors in the skin like Meissner’s corpuscles and Pacinian corpuscles can deform the capsule covering the dendrites of the sensory neurons that they encapsulate. This will open mechanically-gated channels within the dendrites of the sensory neurons and create a graded potential as sodium ions enter the neuron in that region.
