The nervous reflex arc that typically involves a muscle or gland is known as the motor reflex arc. In this arc, sensory neurons transmit signals from a stimulus to the spinal cord, where they connect with interneurons or directly with motor neurons. The motor neurons then send signals to muscles to contract or to glands to secrete substances, resulting in an immediate response to the stimulus. This process enables rapid reactions to environmental changes, such as pulling away from a hot surface.

In the reflex arc a muscle or gland is considered to be the?

In the reflex arc, a muscle or gland is considered to be the effector. Its role is to respond to the stimulus provided by the sensory neuron and produce the appropriate action, such as muscle contraction or gland secretion.


What muscle is the parotid gland close to?

The parotid gland is close to the masseter muscle, which is one of the main muscles responsible for chewing.


An axon of an efferent neuron could synapse with?

An axon of an efferent neuron could synapse with a muscle fiber, gland, or another neuron in the peripheral nervous system.


Which does not constitute part of a two-neuron reflex?

A two-neuron reflex typically involves a sensory neuron carrying information from a sensory receptor to the spinal cord, where it synapses with an interneuron. The interneuron then synapses with a motor neuron that carries the response signal to an effector organ, such as a muscle or gland. In this pathway, a third neuron would not typically be involved in a two-neuron reflex.


What is The Intersection Between A Neuron And Another Neuron A Muscle A Gland Or A Sensory Receptor?

The intersection between a neuron and another neuron, a muscle, a gland, or a sensory receptor is called a synapse. At this junction, the transmitting neuron releases neurotransmitters that bind to receptors on the receiving cell, which can be another neuron, a muscle cell (causing contraction), a gland (triggering secretion), or a sensory receptor (initiating sensory processing). This communication is crucial for nervous system function, allowing for the integration of signals and responses throughout the body.

How does effector relate to reflex arc?

An effector is a part of the body (such as a muscle or gland) that carries out the response in a reflex arc. In a reflex arc, when a stimulus is detected by a sensory receptor, a message is sent via a sensory neuron to the spinal cord, where it is processed, and then a message is sent via a motor neuron to the effector causing a response.


The structure that brings about response in the nervous system?

The effector such as a muscle or gland brings about response in the nervous system.

Smooth muscle, cardiac muscle, gland


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.


First step in a reflex arc?

A reflex arc involves the following components:The receptor is the part of the neuron (usually a dendrite) that detects a stimulus.The sensory neuron transmits the impulse to the spinal cord.The integration center involves one synapse (monosynaptic reflex arc) or two or more synapses (polysynaptic reflex arc) in the gray matter of the spinal cord.A motor neuron transmits a nerve impulse from the spinal cord to a peripheral region.An effector is a muscle or gland that receives the impulse from the motor neuron. In somatic reflexes, the effector is skeletal muscle. In autonomic (visceral) reflexes, the effector is smooth or cardiac muscle, or a gland.


The efferent division of the peripheral nervous system innervates?

A muscle or a gland. Efferent fibers carry information away from the CNS to innervate tissues that perform functions; such as a gland, a smooth muscle, a skeletal muscle, or cardiac muscle. The antonym to efferent would be afferent.


What division of the autonomic nervous system mediates the reflex release of saliva?

The parasympathetic nervous system stimulates salivary gland secretion, and accelerates peristalsis, so, in keeping with the rest and digest functions, appropriate PNS activity mediates digestion of food and indirectly, the absorption of nutrients.

What 3 neurons make up a reflex arc?

There are actual two types of reflex arc. One contains just two and the other contains three.A reflex arc involves the following components:1. The receptor (sensory neuron) that detects a stimulus.The sensory neuron transmits the impulse to the spinal cord.2.The integration center (interneuron) in the cord. This one can be missing. If it is, the reflex is very, very rapid. If the interneuron is used, it can send information up the cord to the brain. Your response will be faster than your brain's "knowing" what happened.3. A motor neuron transmits a nerve impulse from the spinal cord to a peripheral region.An effector is a muscle or gland that receives the impulse form the motor neuron. In somatic reflexes, the effector is skeletal muscle. In autonomic (visceral) reflexes, the effector is smooth or cardiac muscle, or a gland.


What are the structures and functions of a reflex arc?

A reflex is a rapid, involuntary response to a stimulus such as a hot stove.The reflex arc is the pathway traveled by the nerve impulses during a reflex. Most reflexes are pathways that traverse only the spinal cord.During a spinal reflex, information may be transmitted to the brain, but it is the spinal cord that is responsible. They can happen faster than you can think about it.A reflex arc involves the following components:The receptor is the part of the neuron (usually a dendrite) that detects a stimulus (burn).The sensory neuron transmits the impulse to the spinal cord.The integration center involves one, two or more synapses in the gray matter of the spinal cord.A motor neuron transmits a nerve impulse from the spinal cord to a peripheral region.An effector is a muscle or gland that receives the impulse form the motor neuron (remove the hand). In somatic reflexes, the effector is skeletal muscle. In autonomic reflexes, the effector is smooth or cardiac muscle, or a gland.


What best indicated the pathway that nerve impulses travel in a simple reflex?

A simple reflex travels in this order:StimulusA stimulus (stimuli, plural) is an outside happening that affects the body (i.e., sound, sight, taste, pain). 2. Sensory ReceptionThis is when the body senses the stimulus through receptors located all over the body. Some receptors are clustered to form our major sensory organs (i.e., taste buds on tongue).3. Central Nervous SystemSensory neurons transmit the signal to the CNS (brain and spinal cord) through peripheral nerves that connect from the body's extremities to the CNS.If this simple reflex is part of a simple reflex arc (a stimulus that produces some reflexive response), the brain then sends instructions through a motor neuron to an effector (usually a muscle or gland). This prompts either muscle movement or chemical action.
