Answer» Correct Answer - D Autonomic neural system controls internal organs. ANS is divided into 2 parts: (i) Sympethetic neural system-SNS (Thoracicolumbar outflow), (ii) Parasympathetic neural system-PSNS (Craniosacral outflow). SNS is activated under stress condition. SNS increases heart beat while PSNS decreases. SNS constricts arteries (increase BP) while dilates pupil, decreases salivation, tear secretion and increases sweat secretion. ltBrgt PSNS dilates arteries (lower BP) while constricts pupil, increases salivation, peristalsis. |
