To better understand, imagine the following situation. [4] There are upper and lower motor neurons in the corticospinal tract. The fibers of the corticospinal tract terminate at different levels in the anterior horn of the grey matter of the spinal cord. For information, see extrapyramidal system. Biology. Meaning and definition of motor unit : A single motor neuron and all the muscle fibers it controls. A nerve cell that trans mits signals from the brain or spinal cord to muscle s or glands. The sensory system detects signals from the outside environment and communicates it to the body via the nervous system. Meaning and definition of motor division : The efferent neurons that convey information from the CNS to the effector cells. The remaining 5–10% pass to the same side. A Dictionary of Biology. motor synonyms, motor pronunciation, motor translation, English dictionary definition of motor. . Motor proteins are the driving force behind most active transport of proteins and vesicles in the cytoplasm. motor unit ... [>>>] motor neuron s Neuron s that receive signals from interneuron s and transfer the signals to effector cell s that produce a response. However, the effect (stimuli and the responses) of sensory and motor neurons are slightly different from that of afferent and efferent neurons. motor | Definitions for motor from GenScript molecular biology glossary. Electric Motor Definition: Electric motor is the electro-mechanical machine which converts the electrical energy into mechanical energy.In other words, the devices which produce rotational force is known as the motor. Cellular functions. Peripheral structures may include skeletal muscles and neural connections with muscle tissues. ‘His own fleet motor insurance has almost quadrupled in price, from €43,200 to €157,400 in the last three years.’ ‘Previously he had sold milk and motor spare parts.’ ‘However, they spent the least on petrol, diesel and other motor oils at £11.00 a week, compared to a UK average of £14.70.’ 2. a muscle, nerve, or center that effects movements. Each cell is responsible for a single length of the fibre (calle…, Cells motor neuron disease any disease of the motor neurons, including spinal muscular atrophy, progressive bulbar paralysis, amyotrophic lateral sclerosis, and lateral sclerosis. Cite this article Pick a style below, and copy the text for your bibliography. The motor endplate is a modified area of the muscle fibre membrane at which a synapse occurs. Something, such as a machine or an engine, that produces or imparts motion. There are two general types: induction and synchronous. motor definition: 1. a device that changes electricity or fuel into movement and makes a machine work: 2. a car: 3…. Note that “motor” is also used in biology in the sense of “connected with movement of the body that is produced by muscles” so that we can speak of motor skills or the motor cortex in the brain. MOTOR LEARNING: "Motor learning is the process through which we internalize and then utilize new information which allow mastery over our motor functions." -Motor medical term defined and online flashcards. What does MOTOR stand for? n. A single somatic motor neuron and the group of muscle fibers innervated by it. The motor impulses originate in the giant pyramidal cells or Betz cells of the motor area; i.e., precentral gyrus of cerebral cortex. The working of an electric motor is based on the fact that a current carrying conductor produces a magnetic field around it.
