The Nervous System word list, defined
- NEURON /ˈnjʊərɒn/ (British); /ˈnʊrɑːn/ (US) · noun
- A neuron is a specialized cell that transmits information through electrical and chemical signals within the nervous system. Neurons receive signals from other neurons or from sensory receptors and pass them to other neurons, muscles, or glands. Related: nerve cell, neurone.
- SYNAPSE /ˈsaɪ.næps/ · noun
- A synapse is the specialized junction between two neurons, or between a neuron and an effector cell, across which signals are transmitted. The term can also refer more broadly to a site of communication or connection. Related: neural junction, neuronal contact point, connection, junction.
- 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 /ˈmaɪəlɪn/ · noun
- A fatty insulating substance that forms a sheath around many nerve fibres, helping electrical impulses travel rapidly along the nervous system. Related: myelin sheath, nerve insulation, medullary 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 swelling or lump, especially a benign one near a tendon sheath or joint; in anatomy, the term also denotes a bundle of nerve cell bodies that functions as a processing center. Related: swelling, lump, node, knot.
- REFLEX /ˈriːfleks/ · noun, verb, adjective
- An involuntary, automatic response to a stimulus, especially a bodily response or an immediate instinctive reaction. The word can also relate to something turned or sent backward, and as a verb means to bend, turn, or draw sharply backward. Related: response, reaction, automatic response, involuntary reaction.
- SENSORY /ˈsɛnsəri/ · adjective
- Relating to the senses or to the process of receiving sensory information. In medicine and psychology, it describes the organs, pathways, or experiences involved in hearing, sight, touch, taste, smell, and related bodily perceptions. Related: perceptual, sensorial, aural, visual.
