Stimulus, sensory neuron, intermediary neuron, motor neuron and defector organ
is the correct order of general reflex arc.
What is the proper ordering of 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 is the correct order of steps in a reflex arc?
So the reflex arc consists of these five steps in order-
sensor, sensory neuron, control center, motor neuron, and muscle
. These five parts work as a relay team to take information up from the sensor to the spinal cord or brain and back down to the muscles.
What are the 5 parts of a reflex arc?
- sensory receptor.
- sensory neuron.
- integration center.
- motor neuron.
- effector target.
What are the 6 stages of the reflex arc?
- stimulus → receptor →
- sensory neurone → relay neurone →
- motor neurone → effector →
- response.
Which of the following lists the parts of a reflex arc in the correct order?
Effector, receptor, sensory neuron, motor neuron.
What is the correct simple spinal reflex arc?
The correct answer is (d)
receptor, afferent neuron, integration center, efferent neuron, effector
.
What occurs during the reflex arc?
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 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.
What 4 things make up a reflex arc?
The simplest arrangement of a reflex arc consists of
the receptor, an interneuron (or adjustor), and an effector
; together, these units form a functional group. Sensory cells carry input from the receptor (afferent impulses) to a central interneuron, which makes contact with a motor neuron.
Who controls reflex?
The spinal cord
is the primary control centre for reflex behaviour. The spinal cord connects the brain and the spinal nerves. So we can say that, reflex arc is controlled by the spinal cord.
What kind of message will tell the foot to kick the ball?
The
somatic nervous system
carries messages that control body movements. It is responsible for activities that are under your control, such as waving your hand or kicking a ball.
How does a reflex arc work step by step?
- 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 is the function of reflex arc?
A reflex arc is a neural
pathway that controls a reflex
. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
What are the four components of Monosynaptic somatic reflex arc?
- A receptor (in this case, the muscle spindle).
- An afferent component (sensory input).
- A central component (spinal processing).
- An efferent component (motor output).
What is somatic reflex arc?
The somatic reflex arc is
the neural pathway resulting in involuntary actions
, also known as reflexes. … Interneurons integrate the signal (if there are multiple sensory inputs) and transmit the signal to the efferent motor neuron. In normal neural pathways, all input goes to the brain for processing.
