5.1: Objectives

Learning Objectives

• Distinguish between the somatic and autonomic efferent divisions of the nervous system, highlighting their pivotal roles and functions in physiological processes.
• Examine the alternate nomenclatures associated with each division of the autonomic nervous system (ANS).
• Identify the specific points of origin from which neurons emerge from the CNS for each autonomic division.
• Investigate the anatomical disparities between pre- and postganglionic neurons within sympathetic and parasympathetic divisions.
• Discriminate between long and short reflexes within the ANS.
• Recognize and categorize the neurotransmitters released from neurons within the ANS, elucidating their functions.
• Differentiate between antagonistic and complementary/cooperative effects in target organs that receive dual innervation, and analyze how these interactions contribute to overall physiological equilibrium.
• Explain the autonomic division responsible for controlling effector organs lacking dual innervation. Identify the specific organs and tissues under its regulatory influence.
• Locate the various receptor types linked to autonomic efferent innervation, elucidating their roles in mediating responses within target tissues.
• Distinguish between cholinergic and adrenergic nerve supplies within the ANS, emphasizing their distinct neurotransmitter preferences and resultant effects.
• Investigate the precise brain centers involved in regulating and coordinating autonomic motor pathways.
