2.3 Overview of Nervous System Structure Flashcards
microcircuit
Localized interconnected neurons form a microcircuit. They process specific kinds of information and can accomplish sophisticated tasks such as processing sensory information, generating movements and mediating learning and memory.
neural networks
There are long-lasting connections between various brain regions, those are called neural networks, which are macrocircuits that are made up of multiple embedded microcircuits.
autonomic motor system / visceral motor system
The autonomic nervous system is involved in controlling the involuntary action of smooth muscles, the heart and various glands. It has two subdivisions: sympathetic and parasymphathetic branches. In general, the sympathetic system uses the neurotransmitter norepinephrine, and the parasympathetic system uses the neurotransmitters acetylcholine. The two systems frequently operate antagonistically.
meninges
The CNS is made up of the brain and spinal cord, and each is covered with three protective membranes
nucleus
a collection of cell bodies in the central nervous system. Nuclei are located throughout both the brain and the spinal cord.
layer
A common organizational cluster of neurons in the
central nervous system
commissures
Axons may project from one cerebral hemisphere to the other in bundles. The largest of these interhemispheric projections is the main commissure crossing the hemispheres called the corpus callosum.
