An Overview of the Brain and Nervous System

The brain receives input, processes information, and produces output.
The nervous system is divided into the central nervous system (CNS) and peripheral nervous system (PNS).
The PNS consists of the autonomic nervous system (ANS) and somatic nervous system (SNS).
The ANS regulates the internal environment, while the SNS regulates the external environment.
The spinal cord contains motor and sensory neurons and pathways.
Dermatomes refer to the strip of skin innervated by one nerve, while myotomes refer to a group of muscles innervated by the same motor nerve.
The ANS branches into sympathetic and parasympathetic, which have opposite effects on various bodily functions.
The enteric nervous system regulates gut functions.
The brain is organized into different structures, including the forebrain, brainstem, and cerebellum.
Information flows through the brain from inputs to outputs in each region.
Neuromodulation involves the release of acetylcholine, serotonin, norepinephrine, and dopamine to various brain areas.
The cerebellum is involved in refining movements and has connections to the cerebral cortex. The diencephalon includes the thalamus and hypothalamus, which relay information and regulate homeostatic processes.
