Study Notes
Nervous System Overview
- The nervous system is composed of two main components: the Central Nervous System (CNS), which includes the brain and spinal cord, and the Peripheral Nervous System (PNS), which includes nerves that connect the CNS to the rest of the body.
Function of the Nervous System
- The primary function of the nervous system is to control and coordinate body functions, including movement, sensation, perception, and cognitive processes.
Grey and White Matter
- Grey matter is composed of neuronal cell bodies, dendrites, and synapses, and is responsible for processing and integrating information.
- White matter is composed of myelinated axons, which facilitate rapid transmission of signals between different regions of the nervous system.
Neuronal Communication
- Neurons communicate through electrical and chemical signals, which allow them to transmit and receive information.
Peripheral Nervous System
- The PNS is responsible for transmitting signals between the CNS and the rest of the body, allowing for the control of voluntary movements and the reception of sensory information.
Meninges
- The meninges are protective membranes that surround the CNS, providing mechanical protection and immune function.
Sulci and Gyri
- Sulci are grooves and gyri are folds on the surface of the brain, which increase the brain's surface area and allow for more efficient processing and transmission of information.
Signal Transmission
- The PNS is responsible for delivering signals to and from the CNS, allowing for the integration of sensory information and the control of motor responses.
White Matter Function
- The primary function of white matter is to facilitate rapid transmission of signals between different regions of the nervous system.
Reflex Actions
- The spinal cord is responsible for controlling reflex actions, which are automatic responses to sensory stimuli that do not require conscious thought.
