"The motor system is the set of central and peripheral structures in the nervous system that support motor functions, i.e. movement."
The systems that allow the brain to control movement.
Structure and Function of Neurons: Understanding the basic structure of neurons and how they transmit signals is crucial to understanding motor systems.
Motor Cortex: This region of the brain is involved in planning, controlling, and executing voluntary movements.
Basal Ganglia: This group of nuclei in the brain is important for motor control, with disruptions in the basal ganglia implicated in conditions such as Parkinson’s disease.
Cerebellum: This part of the brain is important for motor coordination and balance.
Spinal Cord: The spinal cord plays a critical role in motor function, relaying commands from the brain to the muscles.
Reflexes: Reflexes are automatic, involuntary movements that are triggered by certain stimuli.
Muscle Physiology: Understanding the mechanics of muscles and how they contract is important for understanding motor systems.
Sensory Feedback: Feedback from the senses is essential for the brain to adjust and control movements.
Motor Learning: The process by which the brain learns to control movements requires an understanding of the various mechanisms involved.
Motor Control Disorders: Disorders such as Parkinson’s disease and cerebral palsy can affect motor function and provide insight into how the motor system works.
Neuroplasticity: The brain’s ability to adapt and change in response to experience is crucial to understanding how motor learning occurs.
Development of the Motor System: Understanding how the motor system develops from infancy to adulthood is important for understanding how it functions.
Computational Modeling: Computer models can be used to simulate various aspects of motor control and can provide insights into how the system works.
Brain-Machine Interfaces: These interfaces can be used to enhance or replace motor function and are an exciting area of research in motor systems.
Functional Imaging Techniques: Techniques such as fMRI and PET allow researchers to observe the brain in action during motor tasks and can provide valuable insights into motor systems.
Somatic motor system: Controls voluntary movements of skeletal muscles.
Autonomic motor system: Regulates the activity of smooth muscles, cardiac muscles, and glands.
Sympathetic motor system: Prepares the body for "fight or flight" response by increasing heart rate, constricting blood vessels, and dilating airways.
Parasympathetic motor system: Responsible for "rest and digest" response by causing the heart rate to slow down, dilating blood vessels, and constricting airways.
Enteric motor system: Controls the movements of the gastrointestinal tract, including peristalsis.
Ocular motor system: Controls the movements of the eyes, including convergence, divergence, and movements during saccades.
Vestibular motor system: Regulates balance and spatial orientation by integrating information from the vestibular organs in the inner ear.
Basal ganglia motor system: A group of structures in the brain that regulate movement and posture by modulating signals to the thalamus and cortex.
Cerebellar motor system: Regulates the accuracy and coordination of movements by modulating signals to the primary motor cortex.
Spinal motor system: A system of neurons in the spinal cord that control reflexes and voluntary movements of the limbs, trunk, and head.
"Peripheral structures may include skeletal muscles and neural connections with muscle tissues."
"Central structures include cerebral cortex, brainstem, spinal cord, pyramidal system including the upper motor neurons, extrapyramidal system, cerebellum, and the lower motor neurons in the brainstem and the spinal cord."
