Describe Monosynaptic reflex: When a reflex arc consists of only two neurons in an animal (one sensory neuron, and one motor neuron), it is defined as monosynaptic.Monosynaptic refers to the presence of a single chemical synapse.n polysynaptic reflex pathways, one or more interneurons connect afferent (sensory) and efferent (motor) signals. All but the most simple reflexes are polysynaptic, allowing processing or inhibition of polysynaptic reflexes within the spinal cord.
1-7. REFLEX ARC An impulse follows a conduction pathway from its origin in the dendrites or neuron cell body in one part of the body to the impulse's end somewhere else in the body.One pathway is called a reflex arc and is a functional unit of the nervous system.The basic parts of a reflex arc are a receptor, a sensory neuron, a center, a motor neuron, and an effector. a. Function of Components of a Reflex Arc.Functions are: (1) Receptor. The receptor activates a nerve impulse in a sensory neuron in response to a change in the body's internal or external environment.(2) Sensory neuron. This neuron conducts the impulse from the receptor to its axonal end in the central nervous system.he receptor activates a nerve impulse in a sensory neuron in response to a change in the body's internal or external environment. (2) Sensory neuron. This neuron conducts the impulse from the receptor to its axonal end in the central nervous system.
