Motor nerve - Wikipedia
A motor nerve, or efferent nerve, is a nerve that contains exclusively efferent nerve fibers and transmits motor signals from the central nervous system (CNS) to the muscles of the body. This is different from the motor neuron, which includes a cell body and branching of dendrites, while the nerve is made up of a bundle of axons.
Motor neuron: Anatomy and structure - Kenhub
2023年10月30日 — Motor neurons, also known as efferent neurons, are nerve cells responsible for carrying central nervous system signals towards muscles to cause voluntary or involuntary movement through the innervation of effector muscles and glands. Their nerve fibers are considered to be the longest in the human body.
Motor Neuron: Function, Types, And Structure - Simply Psychology
2023年9月27日 — Motor neurons (also referred to as efferent neurons) are the nerve cells responsible for carrying signals away from the central nervous system towards muscles to cause movement. They release neurotransmitters to trigger responses leading to muscle movement.

2023年7月24日 — Overall, motor neurons (or motoneurons) comprise various tightly controlled, complex circuits throughout the body that allows for both voluntary and involuntary movements through the innervation of effector muscles and glands. The upper and lower motor neurons form a two-neuron circuit.
Motor Neuron - The Definitive Guide - Biology Dictionary
2020年5月13日 — A motor neuron is a cell of the central nervous system. Motor neurons transmit signals to muscle cells or glands to control their functional output. When these cells are damaged in some way, motor neuron disease can arise. This is characterized by muscle wasting (atrophy) and loss of motor function. Motor Neuron.
Nerves: Types, Function & Anatomy - Cleveland Clinic
Sensory nerves carry signals to your brain to help you touch, taste, smell and see. Motor nerves carry signals to your muscles or glands to help you move and function. You also have two main groups of nerves branching out from your brain and spinal cord:
Motor neuron - Wikipedia
A motor neuron (or motoneuron or efferent neuron[1]) is a neuron whose cell body is located in the motor cortex, brainstem or the spinal cord, and whose axon (fiber) projects to the spinal cord or outside of the spinal cord to directly or indirectly control effector organs, mainly muscles and glands. [2] There are two types of motor neuron ...
Motor cranial nerves: Anatomy, functions and components
2023年10月30日 — The oculomotor, trochlear, abducens, accessory, and hypoglossal are motor cranial nerves that are responsible for the motor functions in the head and neck.
Motor Neurone - Physiopedia
Motor neurones are cells in the brain and spinal cord that allow us to move, speak, swallow and breathe by sending commands from the brain to the muscles that carry out these functions. Their nerve fibers are the longest in the body, a single axon can stretch from the base of the spinal cord all the way to the toes.
