the neuron pathway
The short pathway that carries the impulse for an automatic response is called a reflex arc. It involves sensory neurons, interneurons in the spinal cord, and motor neurons to quickly produce a reflex action in response to a stimulus, bypassing the brain.
An automatic reflex arc is a neural pathway that controls reflex actions in response to a stimulus. It involves sensory neurons detecting the stimulus and sending signals to the spinal cord, which then quickly activates motor neurons to produce a rapid and involuntary response, bypassing conscious control from the brain.
Effectors are muscles or glands that bring about a coordinated response in reaction to a stimulus. They execute the commands sent by the central nervous system to produce movements or secretions in response to a specific signal.
A non-reflex arc refers to a neural pathway that does not involve a reflex action, meaning it does not produce an immediate or automatic response to a stimulus. Instead, it may involve more complex processing within the brain, requiring conscious thought or decision-making before a response is generated. This type of pathway is often associated with voluntary movements and higher cognitive functions. Unlike reflex arcs, which operate through spinal cord circuits, non-reflex arcs typically engage various brain regions for processing.
The nervous system and the endocrine system interact to produce a behavioral response. The nervous system sends signals through neurons to initiate a response, while the endocrine system releases hormones that can modulate and sustain that response over time. Both systems work together to coordinate behavioral responses to internal and external stimuli.
A reflex
The short pathway that carries the impulse for an automatic response is called a reflex arc. It involves sensory neurons, interneurons in the spinal cord, and motor neurons to quickly produce a reflex action in response to a stimulus, bypassing the brain.
This process is called classical conditioning, where a neutral stimulus is paired with an unconditioned stimulus until the neutral stimulus alone can produce the same response as the unconditioned stimulus. This creates a conditioned response, where the neutral stimulus now elicits the same response as the unconditioned stimulus.
An automatic reflex arc is a neural pathway that controls reflex actions in response to a stimulus. It involves sensory neurons detecting the stimulus and sending signals to the spinal cord, which then quickly activates motor neurons to produce a rapid and involuntary response, bypassing conscious control from the brain.
our senses will detect stimulus and send impulse into the integrating centre(brain) to interpret. the brain will produce appropriate response toward the stimulus to the effector. e.g when Telephone ring, the ears will detect the stimulus(sound) and the brain will produce the response to pick up the phone (copy from Yahoo answers)
Stimulus?
A reflex pathway is a neural circuit that enables an automatic response to a stimulus without the need for conscious thought. It typically follows a specific path: the sensory receptor detects a stimulus, sends signals through sensory neurons to the spinal cord, where interneurons relay the information to motor neurons, which then activate the appropriate muscles or glands to produce a response. This rapid communication allows for quick reactions, often crucial for survival.
1. Neutral Stimulus(NS)-A stimulus that does not evoke a response 2.Unconditioned Stimulus(US)-A stimulus innately capable of eliciting a response 3.Conditioned Stimulus(CS)-A stimulus that evokes a response b/c it has been paired with an unconditioned stimulus 4.Unconditioned Response(UR)-An innate reflex response elicited by a US 5.Conditioned Response(CR)-A learned response elicited by a CS
When paired with an unconditional stimulus, a neutral stimulus can become a conditioned stimulus and produce the same response as the unconditioned stimulus.
Classical conditioning involves a neutral stimulus acquiring the ability to produce a response that was originally produced by a different stimulus through the process of association. This type of learning was famously demonstrated by Ivan Pavlov's experiments with dogs.
The five stages of the nervous pathway are: 1) Stimulus detection, where sensory receptors detect changes in the environment; 2) Sensory transduction, where the stimulus is converted into electrical signals; 3) Signal transmission, where the signals are transmitted through sensory neurons to the central nervous system; 4) Integration, where the brain processes and interprets the signals; and 5) Response generation, where the brain sends signals to effectors (like muscles or glands) to produce a response. This pathway allows organisms to react to their environment effectively.
A Stimulus is picked up by a receptor, travels along a sensory neurone to either the spinal cord or brain, then it is processed to produce some response.
