APK 3110C Lecture Notes - Lecture 4: Myocyte, Motor Neuron, Sensory Neuron
Document Summary
Inborn (intrinsic): a predictable motor response to a stimulus. Learned (acquired): a reflex that results from practice or repetition. Sensory neuron: transmits afferent impulses to the cns. Integration center: may be a single synapse between a sensory neuron and a motor neuron (monosynaptic) or involve multiple synapses with chains or interneurons (polysynaptic) a. Motor neuron: conducts efferent impulses from the integration center to effector organ. Effector: muscle fiber or gland cell that responds to efferent impulses (by contracting or secreting)
