Med-Surg Nervous System Exam – Foundations, Neuro Anatomy & Nursing Care Verified Questions provided with A+ Graded Rationales Latest Updated 2026 What are the key functions of the nervous system? Control of mobility, sensation, cognition, and involuntary processes. What is involved in the central nervous system? Brain Spinal cord What is involved in the peripheral nervous system? 12 cranial nerves Spinal nerves Autonomic nervous system What are neurons? Cells that transmits impulses within nervous system. Either enhances or inhibits the impulse. What are sensory (afferent) neurons? Control sensation and transmit messages from peripheral nervous system to central nervous system. What are motor (efferent) neurons? Control mobility and transmit messages from central nervous system to peripheral nervous system. What is the function of dendrites in a neuron? Receive information from neurons and transmit message to soma. What is the function of the myelin sheath in a neuron? Fatty substance; provides insulation and allows for fast transmission of impulse. What is the function of the cerebrum? Largest part of the brain that controls motor, cognitive, and sensory function. The two hemispheres control the opposite sides of the body (i.e. left hemisphere controls right side of body). What is the cerebral cortex? Outer layer of cerebrum made up of gray matter. What are the functions of the sub-cortical structures? Hypothalamus, pituitary gland, etc. Memory, emotion, pleasure, hormone production. What is the function of the frontal lobe of the brain? Contains motor cortex. Memory, speech/language, personality, decision-making. What is the function of Broca's area in the frontal lobe of the brain? Essential for speech function. What is the function of the parietal lobe of the brain? Contains sensory cortex. Interpreting signals such as touch, position, temperature, etc. What is the function of the occipital lobe of the brain? Contains visual cortex. Visual processing/interpretation. What is the function of the temporal lobe of the brain? Contains auditory cortex. Hearing/recog
