What is the response of an effector?
to provide a counter stimulus to neurons i hope this helped ^^
Reflexes involve at least three neurons and all arcs through the spinal cord?
Reflexes involve a sensory neuron that detects a stimulus, an interneuron in the spinal cord that processes the information, and a motor neuron that sends the response signal to the muscle or gland. These three neurons work together in a reflex arc to produce a rapid and involuntary response to a stimulus.
How do sensory neurons motor neurons and interneurons work together to produce a response to an environmental stimulus?
This forms what is called a reflex arc. If you would touch a very hot pan, your body will respond very fast to remove your hand before it burns badly. If you had to think about it, the burn would be more severe. So this bypassed the brain and is called a reflex arc. Sensory neurons sends info into the central nervous system (CNS), passes the info to the interneuron and it passes that to the motor neuron. The interneuron also send info to the brain and you note that "that is hot!". If you pay attention to this, you will see that you will remove your hand before you feel the burn.
The response of an effector is?
The response of an effector is the action or change that it produces in response to a stimulus. Effectors are organs or structures in the body that carry out the response, such as muscles contracting in response to a nerve signal. This response helps to bring about homeostasis and maintain the body's internal balance.
When leg muscles respond to a stimulus by moving the foot this response depends on the function of?
Nerves
What stimulus below this intensity will result in no response in a neuron?
Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.
What is a automatic reflex arc?
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.
Is the action potential an all-or-nothing response in neurons?
Yes, the action potential is an all-or-nothing response in neurons, meaning that once a certain threshold is reached, the neuron will fire at full strength regardless of the strength of the stimulus.
A rapid simple automatic response that involves few neurons is?
A reflex action is a fast, automatic response to a stimulus by an effector organ i.e. a muscle.
What is the name of pathway of neurones that impulses in an automatic response follow?
The pathway of neurons that impulses in an automatic response follow is called the reflex arc. This involves sensory neurons detecting a stimulus, sending a signal to the spinal cord, which then processes the information and sends a response via motor neurons back to the muscles or glands.
What is the chain of events for a conscious response starting with stimulus?
A stimulus is perceived by sensory receptors, which then send signals to the brain through the nervous system. The brain processes the information and formulates a response, which is sent back through the nervous system to muscles or glands for action. The response is then carried out, leading to a conscious reaction to the original stimulus.
How is information transferred when movement is fast to a stimulus?
When movement is fast in response to a stimulus, the body sends rapid signals through the nervous system. Sensory neurons detect the stimulus and quickly convey this information to the brain. The brain then processes the information and sends out signals to motor neurons, instructing the body to react accordingly.
