Where does the nerve impulse travel from the reflex arc?
The nerve impulse typically travels from the sensory neuron to the spinal cord, where it is processed by interneurons, and then to the motor neuron to elicit a response from the effector organ or muscle.
How hormones function in a reflex arc?
Hormones have nothing to do in reflex arc.
What kind of reflex arc does not require an inter neuron?
A monosynaptic reflex arc does not require an interneuron. In this type of reflex arc, the sensory neuron communicates directly with the motor neuron in the spinal cord or brainstem, resulting in a quick and simple reflex response.
How may you Explain the role of sensory and motor neurones in a reflex arc.?
what is the role of sensory and motor neurones in a reflex arc
What is the name of a neuron that transmits neural impulse from the sensory neuron to the motor neuron?
A relay neurone passes impulses from a sensory neurone to a motor neurone.
What are the type of nerve cells?
There are three different types of neurone: sensory, relay and motor - which are involved in a reflex arc.
What neurons are involved in a reflex?
3 neurons are included in the reflex arc. They are: Afferent neurons (take the message to the spinal cord) (sensory) Association neurons (directs message to the efferent neuron and the brain) (report reflex to the brain) Efferent neurons (takes message to effector) (motor) Not all reflexes have interneurons.
Where does the nerve impulse travel from the reflex arc?
The nerve impulse typically travels from the sensory neuron to the spinal cord, where it is processed by interneurons, and then to the motor neuron to elicit a response from the effector organ or muscle.
What is a relay nerve cells?
Interneuron (relay neurone) Relays messages from sensory neurone to motor neurone. which make up the brain and spinal cord
Type of neurones along a reflex arc?
the sensory receptor begins then the Relay neuron and final the motor neuron
Where do neurotransmitters act?
They act at the end of a synapse. These are where in the nervous system (relay arc) a relay neurone meets a motor neurone. There is a gap called a synapse between these two neurones and so the only way to transmit the electrical impulse is through neurotransmitters which 'jump' across the gap whilist 'holding' on to the impulse.
What is the path that nervous impulse takes through the nervous system?
A nervous impulse begins in the dendrites of a neuron, travels through the cell body and axon, and then is passed on to the next neuron via a synapse. This sequence repeats until the impulse reaches its destination, such as a muscle or gland, where it triggers a response.
How hormones function in a reflex arc?
Hormones have nothing to do in reflex arc.
Describe the reflex arc?
A reflex arc is the neural pathway that mediates a reflex action. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain will receive sensory input while the reflex action occurs.
What is the pathway of reflex?
reflex arc
How is the structure of a neurone adapted for its job in the reflex arc?
The structure of a neuron is adapted for its role in the reflex arc through specialized components like dendrites to receive sensory input, the cell body to process information, and the axon to transmit signals quickly and efficiently. Additionally, the myelin sheath insulates the axon for rapid signal conduction. This overall architecture helps the neuron to rapidly detect and respond to stimuli in reflex actions.
What are the effectors of a reflex arc?
Muscles and glands are the possible effectors of a reflex arc
