Nervous System MBLEX Questions and Answers Rated A+ Effects of massage/bodywork on the nervous system: - How does massage influence the nervous system? It provides stimulating effects across the nervous system, potentially calming or activating nerves, offers biofeedback to pinpoint tension locations in the body; normalizes both the sympathetic and parasympathetic divisions of the Autonomic Nervous System; releases spasms in tissue around the spinal cord, which can alleviate nerve strain; potentially affects coordination centers through massage of the head and face; and aids in pain management by promoting the release of substances like endorphins. Difference between the autonomic and somatic nervous systems: - What distinguishes the autonomic from the somatic nervous systems? Autonomic: Controls glands, smooth muscles, and heart function. Somatic: Governs voluntary muscle movements. Difference between the central and peripheral nervous systems: - How do the central and peripheral nervous systems differ? Central: Comprises the brain and spinal cord. 2 Peripheral: Includes all nerves connecting the CNS to the body's tissues and organs. Difference between the sympathetic and parasympathetic nervous systems: - How do the sympathetic and parasympathetic nervous systems contrast? Sympathetic: Supplies nerves to glands, involuntary muscles of internal organs, and blood vessel walls, preparing the body for energy-demanding tasks. Parasympathetic: Preserves energy and counters the actions of the sympathetic division. Sciatic nerve: - Describe the sciatic nerve. It is the longest and widest nerve in the human body, extending from the upper leg to the foot's posterior aspect, connecting nearly all skin of the leg, muscles of the back thigh, and those of the leg and foot to the nervous system. Mixed nerve: - What defines a mixed nerve? Nerves that carry both sensory (afferent) and motor (efferent) signals within the same bundle; all spinal nerves are examples of mixed nerves. 3 Efferent nerves: - Define efferent nerves. Nerves that transmit signals from the central nervous system via motor neurons to target muscles and glands, directing movements away from the CNS. Cranial nerves: - What are cranial nerves? Twelve pairs of nerves directly
