monsynaptic reflex arcs
monosynaptic reflex arcs
Please restate this question for clarification...
The pathway that an impulse travels from your foot back to your leg is an example of a reflex arc. A reflex arc includes a sensory receptor (in this case, a receptor in your toe), sensory neuron, motor neuron, and effector (leg muscle). Some reflex arcs include interneurons. In other reflex arcs, a sensory neuron communicates directly with a motor neuron.
Reflexes are uncontrollable movements that happen almost instantly in response to a stimuli. A reflex arc, a neuronal circuit that controls reflexes, is where reflex activities takes place.
ANS reflex arcs are stimulated by input from sensory or visceral receptors. The signals are processed in the hypothalamus (or regions of the spinal cord) and target effector control is then regulated via myelinated preganglionic neurons
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.
A reflex action is an action that happens almost instantly without conscious thought. Grasp a very hot handle of a saucepan on the stove, and you immediately release the handle to avoid further burning by reflex action.
No, it has 2 visceral motor neurons. A visceral reflex has a receptor, a sensory neuron, a processing center, and 2 visceral motor neurons.
Many authors refer to the CNS portion of the reflex arc as the integration center.In regards to a monosynaptic reflex arc, the synapse is the only portion of the integration center.Polysynaptic reflex arcs, have multiple synapses and interneuron(s).
Ganglion
An autonomic reflex arc is similar to the somatic kind, but differs principally in the motor output side. The sensory side is similar in that a transducer sends a signal via a nerve fiber into the CNS. As with the somatic arc, this sensory fiber is associated with a pseudo-unipolar neuron in a craniospinal ganglion, usually one of the dorsal root ganglia. In the autonomic arc, the sensory transducer is often located in or associated with visceral organs.
