Study Guide Overview
This study guide covers the nervous system, focusing on its divisions: the Central Nervous System (CNS) (brain and spinal cord) and the Peripheral Nervous System (PNS). The PNS is further divided into the autonomic (involuntary actions) and somatic (voluntary actions) nervous systems. The autonomic nervous system includes the sympathetic ("fight or flight") and parasympathetic ("rest and digest") divisions. Key concepts include the functions of each division and their roles in various scenarios.
#AP Psychology: Nervous System Study Guide ðŸ§
Welcome to your ultimate nervous system review! Let's make sure you're feeling confident and ready for anything the AP exam throws your way. We'll break down the complex stuff into easy-to-digest pieces and focus on what really matters for test day.
#Overview of the Nervous System
The nervous system is your body's super-fast communication network. It's like the internet, but way cooler. It's divided into two main parts:
- Central Nervous System (CNS): The brain and spinal cord – the command center.
- Peripheral Nervous System (PNS): All the nerves outside the CNS – the messengers.
The CNS processes info and sends out commands, while the PNS relays signals between the body and brain. Think of it like HQ (CNS) sending messages via couriers (PNS) to the troops (body).
#Subsystems of the Nervous System
#Central Nervous System (CNS)
#Functions:
- Consists of the brain and spinal cord, the command centers of the nervous system ðŸ§
- Receives and processes sensory information from all over the body.
- Sends out motor commands to control movement, behavior, and internal processes.
- Integrates and coordinates all neural activity, allowing for complex functions like thought, emotion, and consciousness.
- Stores memories, enables learning, and generates our perceptions and subjective experiences.
#Peripheral Nervous System (PNS)
#Functions:
- Includes all the nerves and ganglia outside the brain and spinal cord.
- Serves as a communication relay between the central nervous system and the rest of the body.
- Collects sensory inform...
