The nervous system can be divided into two major subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS), shown in [link]. The CNS is comprised of the brain and spinal cord; the PNS connects the CNS to the rest of the body. In this section, we focus on the peripheral nervous system; later, we look at the brain and spinal cord.
Peripheral Nervous System
The peripheral nervous system is made up of thick bundles of axons, called nerves, carrying messages back and forth between the CNS and the muscles, organs, and senses in the periphery of the body (i.e., everything outside the CNS). The PNS has two major subdivisions: the somatic nervous system and the autonomic nervous system.
The somatic nervous system is associated with activities traditionally thought of as conscious or voluntary. It is involved in the relay of sensory and motor information to and from the CNS; therefore, it consists of motor neurons and sensory neurons. Motor neurons, carrying instructions from the CNS to the muscles, are efferent fibers (efferent means “moving away from”). Sensory neurons, carrying sensory information to the CNS, are afferent fibers (afferent means “moving toward”). Each nerve is basically a two-way superhighway, containing thousands of axons, both efferent and afferent.

Answer: The unexpected death of his father would be described as an <u>acute stressor</u> for Theo.
Explanation:
- Acute stressor is a traumatic, unexpected experience which results in psychological shock or acute stress disorder (ASD). Symptoms include distressing dreams and frequent flashbacks of the event, lack of sleep, absence of positive emotions, anger, aggression, etc.
- Acute stress differs from chronic stress in that it is short-term, which makes it easier for our body to cope with it. Chronic stress, on the other hand, is long-term and can result in increased blood pressure, heart rate, and other health issues.
- Primary appraisal is one's assessment of a particular event, which includes making a decision if that particular event represents a stressor. Primary appraisal is followed by secondary appraisal, a process in which a person considers how to cope with a particular event.
