motor. (Science: neurology, physiology) A muscle, nerve or centre that effects or produces movement.
What does motor mean in medical terms?
Motor: Something that produces or refers to motion. For example, a motor neuron is a nerve cell that conveys an impulse to a muscle for contraction, which then moves a joint.
What is a motor easy definition?
1 : one that imparts motion specifically : prime mover. 2 : any of various power units that develop energy or impart motion: such as. a : a small compact engine. b : internal combustion engine especially : a gasoline engine. c : a rotating machine that transforms electrical energy into mechanical energy.
What is the main function of motor?
The motor system is the set of central and peripheral structures in the nervous system that support motor functions, i.e. movement. Peripheral structures may include skeletal muscles and neural connections with muscle tissues.
What does motor output mean?
1. Something, such as a machine or an engine, that produces or imparts motion. 2. A device that converts any form of energy into mechanical energy, especially an internal-combustion engine or an arrangement of coils and magnets that converts electric current into mechanical power.
What are motor neurons in psychology?
Motor neurons (also referred to as efferent neurons) are the nerve cells responsible for carrying signals away from the central nervous system towards muscles to cause movement. They release neurotransmitters to trigger responses leading to muscle movement.
What is motor neuron in biology?
Motor neurons are a specialized type of brain cell called neurons located within the spinal cord and the brain. … The latter localize both in the brainstem and the spinal cord and are the mediators between the brainstem and the spinal cord and their peripheral targets, the muscles.
How do motors work physics?
An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor.
What is motor type?
Definition: Electric motor is the electro-mechanical machine which converts the electrical energy into mechanical energy. … The electric motor is mainly classified into two types. They are the AC motor and the DC motor. The AC motor takes alternating current as an input, whereas the DC motor takes direct current.
What is motor impulse?
… impulse traveling in the upper motor neuron from the cerebral cortex in the brain to the spinal cord. The nerve impulse then travels in the lower motor neuron from the spinal cord to the neuromuscular junction, where the neurotransmitter acetylcholine is released.
What is motor control in the brain?
Motor control is the regulation of movement in organisms that possess a nervous system. Motor control includes reflexes as well as directed movement. … Some researchers (mostly neuroscientists studying movement, such as Daniel Wolpert and Randy Flanagan) argue that motor control is the reason brains exist at all.
Where is the motor system?
Body movement relies on the motor systems located in the spinal cord, brain stem, cerebellum, and cerebrum, which communicate with each other via certain pathways.
How does motor neuron function together with sensory neurons?
Sensory cells carry afferent impulses to a central interneuron, which makes contact with a motor neuron. The motor neuron carries efferent impulses to the effector, which produces the response.
What is sensory input integration and motor output?
Sensory input is when the body gathers information or data, by way of neurons, glia and synapses. … After the brain has processed the information, impulses are then conducted from the brain and spinal cord to muscles and glands, which is called motor output.
Which of these functions is handled by motor neurons?
Motor neurones are cells in the brain and spinal cord that allow us to move, speak, swallow and breathe by sending commands from the brain to the muscles that carry out these functions. Their nerve fibers are the longest in the body, a single axon can stretch from the base of the spinal cord all the way to the toes.
