The correct pathway of reflex arc is :
Sensory stimulus → Dentrite of sensory neuron → Axon of sensory neuron → CNS → Dendrite of motor neuron → Axon of motor neuron → Effector organ
.
What is the correct sequence in a typical reflex arc?
Receptors –
Muscle – Sensory neuron – Motor neuron – Spinal cord
.
What is the pathway of a reflex arc?
A reflex arc defines the pathway by which a reflex travels—
from the stimulus to sensory neuron to motor neuron to reflex muscle movement
.
What is the correct pathway in a reflex action?
Reflex arcs
Sensory neuron sends electrical impulses to a relay neuron
, which is located in the spinal cord of the CNS. Relay neurons connect sensory neurons to motor neurons. Motor neuron sends electrical impulses to an effector. Effector produces a response (muscle contracts to move hand away).
What is the correct order of steps in a reflex arc quizlet?
Place the following events of a reflex arc in the correct order: 1) motor neuron activation, 2) sensory neuron activation, 3) sensory receptor activation, 4) Information processing, 5) effector response.
What are the 5 elements of the reflex arc?
- sensory receptor.
- sensory neuron.
- integration center.
- motor neuron.
- effector target.
What is the first component of a reflex arc?
The primary components of the reflex arc are
the sensory neurons (or receptors)
that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action.
Which of the following lists the parts of a reflex arc in the correct sequence?
Which of the following lists the parts of a monosynaptic reflex arc in the correct sequence?
Receptor, sensory neuron, motor neuron, effector
.
How does a reflex arc function?
In a reflex arc,
the sensory neuron sends a signal to the interneuron and activates it
. The interneuron then relays that signal to the next neuron, a motor neuron. Motor neurons connect with interneurons in the spinal cord. They send messages from the central nervous system to the body.
What are the 4 types of reflexes?
In our discussion we will examine four major reflexes that are integrated within the spinal cord:
the stretch reflex, the Golgi tendon reflex, the withdrawal reflex and the crossed extensor reflex
.
Do reflexes involve the brain?
This quick response is called a reflex, and reflexes occur without conscious thinking or planning, meaning
the brain is not involved in them
.
What will happen if we don’t have reflex action?
Most reflexes
don’t have to travel up to your brain to be processed
, which is why they take place so quickly. A reflex action often involves a very simple nervous pathway called a reflex arc. … If the reaction is exaggerated or absent, it may indicate a damage to the central nervous system.
What are the 5 steps of the reflex arc in correct order?
Stimulus, sensory neuron, intermediary neuron, motor neuron and defector organ
is the correct order of general reflex arc.
What are the basic steps of a reflex arc?
- A receptor in the skin detects a stimulus (the change in temperature).
- Sensory neurones send electrical impulses to relay neurones, which are located in the spinal cord. …
- Motor neurones send electrical impulses to an effector.
- The effector produces a response (muscle contracts to move hand away).
What are the 6 stages of the reflex arc?
- stimulus → receptor →
- sensory neurone → relay neurone →
- motor neurone → effector →
- response.
What is reflex arc explain with diagram?
A reflex arc is
a simple nervous pathway which is responsible for the sudden reaction known as the reflex action
. The afferent/sensory neurons are present in the receptor organ which receive the stimulus. The neuron transmits the sensory information from receptor organ to the spinal cord.
