Study Notes
Nervous System
The nervous system is responsible for controlling all bodily functions including sensory perception, movement, thought, learning, memory, emotion, and behavior. It is divided into two main parts: Central Nervous System (CNS) and Peripheral Nervous System (PNS).
Central Nervous System (CNS)
Forebrain
The forebrain includes several structures like the cerebrum, thalamus, hypothalamus, and limbic system. The largest part of the brain, the cerebrum, forms the outer layer of the brain involved in thinking, reasoning, emotions, and voluntary movements.
Midbrain
The midbrain connects the forebrain with the hindbrain and is important for vision, hearing, balance, coordination, and pain and temperature sensation.
Hindbrain
The hindbrain consists of the medulla oblongata, pons, cerebellum, and reticular formation. It controls basic life support functions such as breathing and heart rate.
Cerebellum
Located at the back of the brainstem, the cerebellum plays a crucial role in coordinating body movements.
Spinal Cord
The spinal cord acts as a conduit between the brain and the rest of the body, carrying signals from the brain to muscles and organs and vice versa.
The nervous system works through cycles of electrical impulses moving along nerve fibers, known as action potentials or neural oscillations. Electricity is produced by ion channels located in the cell membrane of neurons, which can either allow positive sodium ions to enter or pump them out, creating electrical gradients within the cell. These gradients create a flow of ions across the membrane, generating signals that are transmitted along nerve fibers.
