- For the musician known as Somatic, see Hahn Rowe. The somatic nervous system (SoNS or voluntary nervous system) is the part of the peripheral nervous system associated with skeletal muscle voluntary control of body movements. The SoNS consists of afferent nerves and efferent nerves.hus somatic nervous system consists of three parts: 1  Spinal nerves: They are peripheral nerves that carry sensory information into and motor commands out of the spinal cord. 2  Cranial nerves: They are the nerve fibers that carry information into and out of the brain stem.

Autonomic nervous system The peripheral nervous system is comprised of two major parts: the somatic nervous system and the autonomic nervous system. The somatic nervous system is that part of the peripheral nervous system associated with voluntary muscle movements.The autonomic nervous system is the one that is involved primarily in supplying stimulation from the motor nerves to the involuntary muscles and to the glands of the body.Therefore, it is associated with bodily functions such as digestion, respiratory rate, micturition, heart rate, and so on.upplement. The peripheral nervous system, together with the central nervous system, makes up the nervous system. In vertebrates, the peripheral nervous system is not found inside the skull and vertebral column just as central nervous system is.

- The sensory (afferent) division carries sensory signals by way of afferent nerve fibers from receptors in the central nervous system (CNS). It can be further subdivided into somatic and visceral divisions. The somatic sensory division carries signals from receptors in the skin, muscles, bones and joints.he anterior horn cells, although technically part of the central nervous system (CNS), are sometimes discussed with the peripheral nervous system because they are part of the motor unit. In the peripheral nervous system, bundles of nerve ﬁbers or axons conduct information to and from the central nervous system.

THE NERVOUS SYSTEM The vertebrate nervous system is divided into a number of parts. The central nervous system includes the brain and spinal cord. The peripheral nervous system consists of all body nerves. Motor neuron pathways are of two types: somatic (skeletal) and autonomic (smooth muscle, cardiac muscle, and glands).he Autonomic Nervous System is that part of PNS consisting of motor neurons that control internal organs. It has two subsystems. The autonomic system controls muscles in the heart, the smooth muscle in internal organs such as the intestine, bladder, and uterus.

- Skeletal muscle fibers are the effectors of the somatic nervous system and smooth muscle is the common effector of the autonomic nervous system. As the effectors of the somatic nervous system that controls skeletal movement muscles are arranged in antagonistic pairs. Relaxation of an effector muscle does not allow the body to return to a previous position. Antagonous contraction and relaxation by opposing muscles also stops appendages flopping about!

- Motor nerves or motor neurons are a type of cell located in the central nervous system (CNS) that have axons extending outside the CNS to directly or indirectly control muscle contraction. Read on to learn more about motor neurons, and the role they play in your body.

Exercise 16: Nervous Tissue Motor, or efferent neurons: carry impulses from the central nervous system to effectors, such as muscles or glands. Interneurons: receive signals from sensory neurons, integrate information and send signals to motor neurons. Somatic fibers relate to the skin and its derivatives, and to voluntary muscles.

Autonomic Nervous System - Anatomy & Physiology Basic Principles. Within the somatic nervous system, the link between the skeletal muscle cell and the central nervous system consists of a single nerve fibre. Within the ANS, efferent signals are transmitted by two neurons between the CNS and the effector cells.

The peripheral nervous system consists of all body nerves. Motor neuron pathways are of two types: somatic (skeletal) and autonomic (smooth muscle, cardiac muscle, and glands).he Peripheral Nervous System (PNS)contains only nerves and connects the brain and spinal cord (CNS) to the rest of the body. The axons and dendrites are surrounded by a white myelin sheath. Cell bodies are in the central nervous system (CNS) or ganglia.

What Is the Function of the Motor Nerves? There are three types of motor nerves. Somatic motor nerves control skeletal muscles, which cause movement. Special visceral motor nerves control muscles in the face and neck. General visceral motor nerves control the smooth muscles that lack voluntary control, such as the heart. Another term for a motor nerve is motor neuron.. Motor nerves work by sending chemicals, known as neurotransmitters, across a gap between the nerve and the muscle. The neurotransmitters bind to receptors in the muscle fiber and trigger movement.

- 15. Nervous System: Autonomic Nervous System I. Comparison of the Somatic and Autonomic Nervous Systems The somatic nervous system is fairly straightforward. It consists of somatic motor neurons with bodies located in the brain or spinal cord and axons that extend through cranial or spinalnerves. The axons of somatic motor neurons synapse with skeletal muscles. All somatic motorneurons release the neurotransmitter acetylcholine (ACh) from their synaptic knobs. ACh isalways excitatory at synapses with skeletal muscle fibers; a synapse between a motor neuron anda muscle fiber is called a neuromuscular junction.

Learn About the Peripheral Nervous System Peripheral Nervous System. 1  Sensory Nervous System - sends information to the CNS from internal organs or from external stimuli. 2  Motor Nervous System - carries information from the CNS to organs, muscles, and glands. Somatic Nervous System - controls skeletal muscle as well as external sensory organs.
