What role does the brain play in a reflex response?
withdrawal reflex involves the processing of brain. it integrates with cerebellar activity
How does the mechanoreceptor reflex effect breathing?
The mechanoreceptor reflex is composed of the inflation reflex and the deflation reflex. The inflation reflex limits the duration of inspiration in response to stretching the walls of the lungs. The deflation reflex stimulates inspiration when the lungs are collapsed. Mechanoreceptor reflexes are insignificant during quiet respiration but they are very important during forced respiration. The mechanoreceptor reflex makes sure your brain knows when to stop breathing and start breathing, basically.
What is a neural transmission that bypasses the brain?
Reflex arc
Why does reflex reinforcement work?
Instead of being processed in the brain, a reflex arc is processed in the vertebra, this allows for faster reflexes. Example of when the reflex arc is used is when a person touches a hot stove. The immediate response (which the reflex arc causes) is to pull away, but it doesn't really hurt till a few seconds after. This is because the brain was first bypassed, but has now had time to process what happened.
Which part of the brain participates in the baroreceptor reflex?
medulla oblongata
During a reflex the nerve impulse reaches?
the brain
Can part of the impulse in a reflex action reach the brain?
because it is the cells
If you are stung by a bee you don't feel any pain until the impulse reaches your?
When stung by a bee a person will not feel any pain until the impulse reaches their brain. The brain is the center of a humans nervous system.
When ever you get stung by a bee you don't fill it until the impulse reaches your?
When you are stung by a bee you don't feel it until the impulse reaches your brain. The signal travels along your nerves to your spinal cord, where it is turned into a chemical message and sent to your brain.
What is the path that nervous impulse takes through the nervous system?
sensory neurone --> enters spinal cord --> relay neurone --> brain(is not a reflex action) or motor neurone(if action is reflex)
What is the difference between a reflex arc and a normal nerve impulse?
A reflex arc doesn't go all the way up to the brain. Thus it NEVER becomes part of the thought process.
How does the four major elements of a simple nervous pathway function during pain withdrawal reflex?
During a pain withdrawal reflex impulses are sent through different nerves and to the spinal cord. This reflex does not make it to the brain but only to the spinal cord. We call this involuntary action because we dont control reflexes. The sensory neurons are the first to recieve the impulse, then they travel to the interneurons, or associative neurons, and then they go to the motor neurons which carries the impulse to the central nervous system. Then the effector is the response, so in this case your musscle will contract.
How does information from the sensory receptorsin the skin get to the brain?
The initial sensory receptor detects a change e.g temperature. This is sent as an electrical impulse via a series of sensory receptors to the spine, if there is a problem a reflex occurs. If there is no problem the impulse is transmitted to the brain through the spinal cord.
A reflex arc begins with the stimulation of a what?
A reflex arc begins with the stimulation of a sensory receptor such as those on the skin. The stimulus is then passed as an electrical impulse along sensory, relay and motor neurones (by-passing the brain) before reaching an effector orgen, like a muscle, which then responds to the stimulus.
Electrical impulses bypasses what area of the brain?
The electrical impulse bypasses the concious areas of your brain so you don't think about subconcious things, like reflex actions for example. This is to help you in dangerous situations and to help you survive.
The knee jerk reflex is an example of a?
A reflex is a rapid, involuntary response to a stimulus. A reflex arc is the pathway traveled by the nerve impulses during a reflex.Most reflexes are spinal reflexes with pathways that traverse only the spinal cord. During a spinal reflex, information may be transmitted to the brain, but it is the spinal cord, and not the brain, that is responsible for the integration of sensory information and a response transmitted to motor neurons.Information is sent to the brain but that takes awhile longer. It is best if you remove your hand from the fire as fast as possible and not wait until the brain yells "hot, hot!".
What type of reflex does not involve the brain?
Patellar Reflex.
