Study Notes
Overview of the Nervous System
- The nervous system is a complex system that allows the body to respond to stimuli, adapt to changes, and maintain homeostasis.
- It consists of two main parts: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
Central Nervous System (CNS)
- Consists of the brain and spinal cord.
- Responsible for integrating and processing information from sensory receptors.
- Acts as the "control center" of the body.
Peripheral Nervous System (PNS)
- Consists of nerves that connect the CNS to the rest of the body.
- Divided into two subsystems:
- Somatic Nervous System: controls voluntary movements and receives sensory information from the environment.
- Autonomic Nervous System (ANS): controls involuntary actions, such as heart rate, digestion, and breathing.
Functions of the Nervous System
- Sensation: receives and interprets sensory information from the environment.
- Integration: processes and analyzes sensory information.
- Motor Control: transmits signals to muscles and glands to respond to stimuli.
- Regulation: maintains homeostasis and regulates body functions.
Types of Neurons
- Sensory Neurons: transmit sensory information to the CNS.
- Motor Neurons: transmit signals from the CNS to muscles and glands.
- Interneurons: integrate and process information within the CNS.
Neurotransmission
- Neurotransmitters: chemical messengers that transmit signals between neurons.
- Synapse: the gap between the terminal end of one neuron and the receptor site of another.
- Synaptic Transmission: the process by which neurotransmitters are released and bind to receptors.
Functions of Glial Cells
- Support: provide structural and nutritional support to neurons.
- Protection: protect neurons from injury and infection.
- Maintenance: maintain the health of neurons and remove waste products.
Nervous System Overview

Central Nervous System (CNS)
- The CNS consists of the brain and spinal cord.

- It acts as the "control center" of the body.
Peripheral Nervous System (PNS)
- The PNS consists of nerves that connect the CNS to the rest of the body.
- It is divided into two subsystems: Somatic Nervous System and Autonomic Nervous System (ANS).
- The Somatic Nervous System controls voluntary movements and receives sensory information from the environment.
- The Autonomic Nervous System (ANS) controls involuntary actions, such as heart rate, digestion, and breathing.
Nervous System Functions
- The nervous system receives and interprets sensory information from the environment through sensation.
- It processes and analyzes sensory information through integration.
- It transmits signals to muscles and glands to respond to stimuli through motor control.
- It maintains homeostasis and regulates body functions through regulation.
Types of Neurons
- Sensory neurons transmit sensory information to the CNS.
- Motor neurons transmit signals from the CNS to muscles and glands.
- Interneurons integrate and process information within the CNS.
Neurotransmission
- Neurotransmitters are chemical messengers that transmit signals between neurons.
- The synapse is the gap between the terminal end of one neuron and the receptor site of another.
- Synaptic transmission is the process by which neurotransmitters are released and bind to receptors.
Glial Cells
- Glial cells provide structural and nutritional support to neurons.
- They protect neurons from injury and infection.
- They maintain the health of neurons and remove waste products.
