WebbThe whole process is called the mechanism of muscle contraction and it can be summarized in three steps: (1) A message travels from the nervous system to the muscular system, triggering chemical reactions. (2) The chemical reactions lead to the muscle fibers reorganizing themselves in a way that shortens the muscle--that’s the contraction. WebbA motor neuron is basically a nerve cell whose function is to respond to sensory stimulation by producing the required muscular movement. Motor neurons are located in the spinal cord, and their axon protrudes outside …

The motor neurons run out of the spinal cord and connect with a muscle. Motor neurons, like sensory neurons, can be quite long, connecting the spinal cord with our most distant appendages. Webb28 apr. 2024 · There are many different types of reflexes, but the most basic is called a simple reflex. A simple reflex contains only one space where information in the spinal cord travels between two nerve cells, called neurons. The space between two neurons is called a synapse.

WebbDoes the brain send it messages? Muscles move on commands from the brain. Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles.
