Motor (medicine)

Motor (pronunciation: /ˈmoʊtər/), in the field of medicine, refers to the aspect of the nervous system that is responsible for movement. The term is derived from the Latin word 'motor', meaning 'mover'.

Etymology

The term 'motor' is derived from the Latin word 'motor', which means 'mover'. It was first used in the context of neurology in the late 19th century to describe the part of the nervous system responsible for controlling movement.

Definition

In medical terms, 'motor' refers to the neurons or nerves that carry signals from the brain and spinal cord to the muscles, causing them to contract and produce movement. This is in contrast to sensory neurons, which carry signals from the body to the brain and spinal cord.

Related Terms

  • Motor neuron: A type of nerve cell that is directly responsible for controlling muscles. Motor neurons receive signals from the brain and spinal cord and transmit them to the muscles, causing them to contract.
  • Motor cortex: The part of the brain that is primarily responsible for controlling voluntary movement. The motor cortex sends signals to the motor neurons, which then cause the muscles to contract.
  • Motor skills: The ability to perform movements with precision and control. Motor skills are controlled by the motor cortex and motor neurons.
  • Motor system: The part of the nervous system that is responsible for controlling movement. The motor system includes the motor cortex, motor neurons, and the muscles themselves.
  • Motor disorder: A condition that affects the motor system, causing problems with movement. Motor disorders can be caused by damage to any part of the motor system, including the motor cortex, motor neurons, or muscles.
