Detailed explanation-1: -Motor Neurons-Transmit impulses from the brain and spinal cord to the muscles and glands, directing body actions. Interneurons-Neurons that form bridges to transmit impulses between other neurons.
Detailed explanation-2: -Answer and Explanation: Efferent neurons are motor cells that carry information from the brain to effector cells. Efferent pathways carrying messages from the brain to other parts of the body telling them what to do.
Detailed explanation-3: -Neurons are the nerve cells that transmit impulses. Supporting cells are neuroglia. The three components of a neuron are a cell body or soma, one or more afferent processes called dendrites, and a single efferent process called an axon. The central nervous system consists of the brain and spinal cord.
Detailed explanation-4: -Impulses are carried along one or more of these fibres, called dendrites, to the cell body; in higher nervous systems, only one fibre, the axon, carries the impulse away from the cell body. Bundles of fibres from neurons are held together by connective tissue and form nerves.
