Guida verificata passo dopo passo1
Understand the components of a reflex arc: A reflex arc typically involves a sensory neuron (afferent), a motor neuron (efferent), and sometimes one or more interneurons.
Identify the types of reflex arcs: Reflex arcs can be classified as monosynaptic or polysynaptic based on the number of synapses involved.
Define a monosynaptic reflex arc: A monosynaptic reflex arc involves only one synapse between the afferent neuron and the efferent neuron, meaning there are no interneurons involved.
Compare with other types: A polysynaptic reflex arc involves one or more interneurons, leading to multiple synapses. An autonomic reflex arc involves the autonomic nervous system, and a somatic reflex arc involves the somatic nervous system.
Conclude that a monosynaptic reflex arc consists of only an afferent neuron and an efferent neuron, with a direct synapse between them.
