efferent neuron

An efferent neuron, also known as a motor neuron, is a nerve cell that transmits signals from the central nervous system (CNS) to effectors like muscles or glands. These signals cause muscles to contract or glands to secrete substances, enabling movement and bodily functions. Unlike sensory neurons, which carry information to the CNS, efferent neurons carry commands away from it.12

Efferent neurons are crucial for voluntary and involuntary movements. For instance, they are involved in the contraction of skeletal muscles for actions like walking, as well as smooth muscles in organs for processes such as digestion and breathing. The transmission of these signals is vital for the body to interact with its environment and maintain internal balance.31
