Your alarm clock woke you up early in the morning as a signal that you need to prepare for class. You stretched, yawned, and began to salivate as you smell the brewing coffee. Your stomach also begins to rumble. List the divisions of the nervous system that are involved in each of these responses
Hearing the alarm clock (sensory), stretching (motor), and smelling the brewing coffee (sensory) involve the somatic nervous system. Yawning (parasympathetic) and salivating (salivary secretion is regulated by the parasympathetic and sympathetic) involves the autonomic nervous system. The rumbling of the stomach (motor) involves the enteric nervous system.
