Nervous System and Contractions/El sistema nervioso y las contracciones musculares

En esta lección vamos a repasar cómo el sistema nervioso juega un papel en la contracción muscular.

TERMS TO KNOW
  • Motor Neuron

    A neuron that delivers signals to muscles or glands.

  • Sarcomere

    The basic units of muscle contractions.

  • Calcium

    An ion necessary for muscle contractions to occur.

  • Actin

    A protein referred to as the "thin filaments" involved in contractions.

  • Myosin

    A protein referred to as the "thick filaments" involved in contractions.

  • Neuromuscular Junction

    The area where the end of a motor neuron comes close to a muscle fiber.

  • Synapse

    The gap between the end of a motor neuron and a muscle fiber.

  • Neurotransmitter

    A chemical messenger that carries signals across the synapse between cells.

  • ​Troponin

    A protein found on actin filaments that plays a role in muscle contractions.

  • ​Tropomyosin

    A protein found on actin filaments that plays a role in muscle contractions.
