Study Notes
- Reflexes are quick, involuntary responses to specific stimuli.
- Maintain homeostasis by making swift adjustments in the function of organs or organ systems.
- Reflex arc: sequence of events leading to a reflex response.
- Components of reflex arc:
- Receptor: identifies stimulus.
- Sensory neuron (afferent): conveys information to the spinal cord.
- Motor neuron (efferent): transmits information to an effector.
- Interneuron: located in the spinal cord, links sensory neuron to motor neuron.
- Effector: muscle fibers contract or another organ that produces the reflex action (secretion from a gland).
