The Nervous System word list, defined
- NEURON /njuːrɒn/ · noun
- A cell in the nervous system that processes and transmits information through electrical and chemical signals. Neurons are the basic building blocks of the brain and nervous system. Related: nerve cell, ganglion cell, neuroglia, synapse.
- SYNAPSE /sɪˈnæps/ · noun
- A synapse is a small gap between two neurons across which chemical signals pass. It is a crucial part of the nervous system, enabling communication between neurons. Related: connection, link, junction, interface.
- AXON /ˈak.sɒn/ · noun
- The long, slender fiber of a neuron that conducts electrical impulses away from the nerve cell body toward other neurons, muscles, or glands. Related: nerve fiber, neurite.
- DENDRITE /ˈdɛn.draɪt/ · noun
- A short branching extension of a nerve cell (neuron) that receives electrical signals from other cells; also, a branching, tree-like crystalline structure or mineral formation. Related: branch, arborization, process.
- MYELIN /ˈmaɪ.ə.lɪn/ · noun
- A fatty insulating substance that surrounds the nerve fibers of the vertebrate nervous system. Related: myeline, medullary substance, fatty sheath, nerve sheath.
- CEREBRUM /ˈsɛrɪbrəm/ · noun
- The cerebrum is the largest and most highly developed part of the brain, consisting of two hemispheres and responsible for higher functions such as thought, reasoning, memory, and voluntary movement. Related: brain, cerebral cortex, grey matter, encephalon.
- CEREBELLUM /ˌsɛrəˈbɛləm/ · noun
- The large, ridged structure at the back of the brain, below the cerebrum, responsible for coordinating voluntary movement, balance, and posture. Related: little brain.
- BRAINSTEM /ˈbreɪnstɛm/ · noun
- The stalk-like portion of the brain that connects the cerebrum and cerebellum to the spinal cord, comprising the midbrain, pons, and medulla oblongata. It controls many automatic functions essential to life, including breathing, heart rate, and reflexes. Related: brain stem.
- CORTEX /ˈkɔːr.tɛks/ · noun
- The outer layer of an organ or structure, especially the deeply folded grey matter covering the cerebrum of the brain, responsible for higher functions such as thought, language, memory, and perception. Related: outer layer, grey matter, mantle, covering.
- GANGLION /ˈɡæŋɡliən/ · noun
- A ganglion is a mass of nerve tissue or a knot of nerve fibers, often found in the skin or other parts of the body. It can also refer to a swelling or lump, especially one that is caused by a collection of fluid or a tumor. Related: knot, swelling, lump, tumor.
- REFLEX /rɪˈflɛks/ · noun, verb
