The Nervous System

Study Notes

Introduction to the Nervous System

The nervous system has four primary functions: sensing the world through vision, hearing, smell, taste, and touch; transmitting information; processing information; and producing a response.
The main tractology in the nervous system involves three processes: sensory input, integration, and motor output.
Sensory input involves gathering information to monitor changes occurring inside and outside the body.
Integration refers to processing and interpreting sensory input to decide if action is needed.
Motor output is a response to integrated stimuli that activates muscles or glands.
The nervous system is composed of two main divisions: the Central Nervous System (CNS), which includes the brain and spinal cord, and the Peripheral Nervous System (PNS), which includes nerves.
There are two types of motor actions: somatic, which happens in skeletal muscles and is voluntary, and autonomic, which happens in smooth and cardiac muscles and is involuntary.
The autonomic motor actions have two parts: sympathetic and parasympathetic.
The nervous system is made up of cells called neurons.
Neurons are specialized cells that transmit electrical signals and communicate with each other through chemical signals.
The nervous system is responsible for coordinating and controlling the body's functions and maintaining homeostasis.
Understanding the nervous system is essential for studying human anatomy and embryology.
