The signals from the neurotransmitters are set through the upper motor neuron to the skeletal muscle through the axons. It releases from the axon and acts on the acetylcholine receptors in the muscles for contraction. The somatic nervous system controls the information when any of your senses are used for an action.Īcetylcholine is an excitatory neurotransmitter, also working as an autocrine hormone, that stimulates movements in the somatic nervous system. It also contributes to the input of the senses. The afferent nerves pick up the signals, and the efferent nerves direct the muscles. The somatic nervous system contains the efferent and the afferent nerves involved in the to and fro transport of information. It manages the skeletal muscles voluntarily. It is involved in the voluntary action of the muscles signals. The somatic nervous system is the voluntary nervous system. The somatic and autonomic nervous systems are divisions of the peripheral nervous system. The exchange of information takes place in the form of nerve impulses between neurons. The dendrites receive signals, and the axon transmits signals to other neurons.
The cell body (soma) of the neuron makes sure everything is working fine. They send, receive, and transmit signals across the body. Neurons are the fundamental unit of the nervous system, including the sensory, motor, and mixed neurons. These nerves transport information to and from the central nervous system to other body parts. In contrast, those branching from the spinal cord are spinal nerves. The nerves coming out of the brain are called cranial nerves. The peripheral nervous system consists of all nerves and nerve branches arising from the brain and spinal cord. & parasympathetic Movement Voluntary Involuntary Muscle Type Skeletal muscles Smooth andĬardiac muscles Neurotransmitters Excitatory Excitatory & inhibitory Complexity Less complex More complex Examples Skeletal muscle movement Stomach, heart, pupil What is Peripheral Nervous System?
