PPT-PNS; THE REFLEX ARC AND GENERAL PROPERTIES OF SPINAL REFLEXES

REFLEX Reflex is an involuntary response to stimulus REFLEX ARC Reflex Arc is the basic unit of integrated reflex activity It consists of Sense organ an afferent neuron one or more synapses that are generally in a central integrating area an efferent neuron an effector organ . Integrative Physiology I: . Control of Body Movement. About this Chapter. Neural reflexes. Autonomic reflexes. Skeletal muscle reflexes. The integrated control of body movement. Control of movement in visceral muscles. Objectives:. To describe the pathway nervous impulses travel through a reflex. To observe reflexes and reaction times. Journal: List the layers of protection around the central nervous system from the vertebrae to the spinal cord. . Reflexes are natural physical responses a baby has that helps him or her to survive outside of the womb. Many reflexes which are present at birth will generally subside within a few months as the baby grows and matures. While some reflexes may be more prominent in certain babies, reflexes help pediatricians identify if a baby is growing and maturing as he or she should be. . Chapter 13 Part 4. Anatomy &Physiology.
