Which part of a reflex arc would have a cell body in the posterior root ganglion?
The sensory (afferent) neuron has a cell body located in the posterior root ganglion of the spinal nerve. This neuron carries sensory information from the peripheral receptors to the central nervous system.
What is the first event associated with a reflex?
The first event associated with a reflex is the stimulus, which activates sensory receptors in the body. These receptors then send a signal to the spinal cord, bypassing the brain to produce a quick response from motor neurons, resulting in the reflex action.
Which reflex arcs contain no association neuron?
The patellar reflex is an example of a 2-neuron reflex arc. It has 1 sensory neuron and 1 motor neuron. It does not contain an association neuron and so is considered the most simple reflex in humans.
What is the processing center of a visceral reflex?
The processing center of a visceral reflex is typically located in the central nervous system, such as the brain or spinal cord. This is where the information from sensory receptors is integrated and a response is generated to regulate internal organ function.
The sensory receptor sensory neuron motor neuron and effector involved in a reflex form a?
The sensory receptor, sensory neuron, motor neuron, and effector involved in a reflex form a reflex arc. This is a neural pathway that controls a reflex action in response to a stimulus without conscious thought.
Where are the sensory receptors of a withdrawal reflex located?
bull
The sensory receptors of a withdrawal reflex are located in the what?
Skin.
Where are sensory stretch receptors of the withdrawal reflex located?
they are located in the limbs, because the limbs are the effectors of the withdrawal reflex.
A withdrawal reflex employs what neurons?
Withdrawal reflex or flexor reflex employs sensory neuron, interneuron and motor neuron.
Which is the first structure stimulated in a reflex arc?
Sensory receptors.
What interneurons in a withdrawal reflex are located in the?
The interneurons involved in a withdrawal reflex are located in the spinal cord. These interneurons receive signals from sensory neurons that detect the painful stimulus and transmit signals to motor neurons that cause the withdrawal response. The spinal cord acts as a relay station for these signals, allowing for a quick and automatic response to potential harm.
What is a movement caused by the spinal cord interpreting an impulse from sensory receptors?
a reflex
A response caused by the spinal cord interpreting an impulse from sensory receptors?
Reflex
Where are most sensory receptors located?
In the human being, it is the eye. Hence the ancient method of "stick a needle in your eye" to prove death. No reflex, no life.
What reflex has at least one interneuron placed between the sensory and motor neurons?
The withdrawal reflex, such as the withdrawal of a hand from a hot stove, involves at least one interneuron placed between the sensory neuron carrying the pain signal and the motor neuron causing the muscle to move away from the source of the pain.
Does a withdrawal reflex employ a converging circuit?
Yes, a withdrawal reflex typically involves a converging circuit in the spinal cord where sensory input from multiple sensory neurons converge onto a single motor neuron. This allows for a rapid and coordinated response to a potentially harmful stimulus.
What is the name of the reflex associated with the sensory stimulation of the pulmonary stretch receptors that stimulates a deeper breath upon inspiration?
The reflex associated with the sensory stimulation of the pulmonary stretch receptors is known as the Hering-Breuer reflex. It is responsible for inhibiting inspiration to prevent overinflation of the lungs, promoting expiration and maintaining normal breathing patterns.
