[Solved] Which of the following is controlled by the somatic motor [1]
Which of the following is controlled by the somatic motor. Which of the following is controlled by the somatic motor division? A) smooth muscle B) skeletal muscle C) cardiac muscle D) glands
Further, the latter has two divisions, namely somatic and autonomic. The somatic division of NS comprises nerves that relay the sensory information from the skeletal muscles, muscles that can be controlled at will (voluntarily) to the brain
Cardiac muscles, smooth muscles, and glands show involuntary activity, and thus, they are regulated by autonomic NS, not somatic NS. Receptors on a postsynaptic CNS neuron bind glutamate
Organization of the Nervous System [2]
Although terminology seems to indicate otherwise, there is really only one nervous system in the body. Although each subdivision of the system is also called a “nervous system,” all of these smaller systems belong to the single, highly integrated nervous system
The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).. The brain and spinal cord are the organs of the central nervous system
The brain is in the cranial vault, and the spinal cord is in the vertebral canal of the vertebral column. Although considered to be two separate organs, the brain and spinal cord are continuous at the foramen magnum.

Treasure Island (FL): StatPearls Publishing; 2023 Jan-.. The somatic nervous system is a component of the peripheral nervous system associated with the voluntary control of the body movements via the use of skeletal muscles
A substantial portion of the peripheral nervous system is the 43 different segments of nerves- 12 pairs of cranial and 31 pairs of spinal nerves, which help us perform daily functions. The somatic nervous system consists of both afferent (sensory) and efferent (motor) nerves [1]
What is the Somatic Nervous System? [4]
You settle down on your couch and decide to read a book lying on your coffee table. In response to this thought, your brain sends a signal to your arm and causes skeletal muscle contraction, which enables you to pick up the book
Guess what? In both instances, you’ve used your somatic nervous system. Please continue reading to learn more about this vital part of the human body.
The central nervous system is made up of the brain and spinal cord. The peripheral nervous system consists of all the nerves that connect the central nervous system and various parts of the body, such as the organs, glands, and muscles.
Somatic Nervous System: What It Is & Function [5]
Your somatic nervous system is a subdivision of your peripheral nervous system that stretches throughout nearly every part of your body. The nerves in this system deliver information from your senses to your brain
What’s the difference between the somatic and autonomic nervous systems?. Your somatic nervous system involves things you can consciously sense and do
Both are subdivisions of the peripheral nervous system, a subsystem of your overall nervous system.. All but one of your senses travel through your somatic nervous system to reach your brain (sight is the exception because your retina and optic nerve connect directly to your brain)

All the terminology that gets thrown around when you’re studying the nervous system can be a little overwhelming. Autonomic, parasympathetic, somatic, peripheral…how many nervous systems can one person have?!
It turns out that when we say “the” nervous system, we’re really referring to one entity that has a bunch of different divisions that work together to achieve a common goal (keeping you alive). The map we’re creating is going to help us learn about all of these different pieces of the nervous system, what they do, and how they communicate with each other.
I placed the CNS a little higher than the PNS because even though the PNS isn’t part of the CNS, the CNS is technically “in charge.”. The CNS is composed of the brain and the spinal cord
Somatic nervous system [9]
This article needs additional citations for verification. The somatic nervous system (SNS), or voluntary nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles.[1][2]
The a- of afferent and the e- of efferent correspond to the prefixes ad- (to, toward) and ex- (out of).. There are 43 segments of nerves in the human body.[4] With each segment, there is a pair of sensory and motor nerves
Thus the somatic nervous system consists of two parts:. – Spinal nerves: They are mixed nerves that carry sensory information into and motor commands out of the spinal cord.[5]
What is the primary difference between the somatic nervous system… [10]
What is the primary difference between the somatic nervous system and the autonomic nervous system?. The autonomic nervous system enables us to control our involuntary muscles, while the somatic nervous system controls our glands.
The autonomic nervous system allows us to consciously control our skeletal muscles, and the somatic nervous system controls activity that humans cannot consciously control, such as the pumping of the heart and the movement of food through the digestive tract.. The somatic nervous system enables us to control our involuntary muscles, while the autonomic nervous system controls our glands.
The Nervous System [11]
This page outlines basic concepts related to the nervous sytem.. Separate pages describe the brain and spinal cord, and
information on a variety of levels, and directs the body to respond. The basic organization of the nervous system follows
receptors throughout the body, including the skin, eyes, ears, nose, tongue. as well as pain and other receptors in the internal organs.
Peripheral Nervous System Anatomy: Overview, Gross Anatomy, Microscopic Anatomy [12]
The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions
In the peripheral nervous system, bundles of nerve fibers or axons conduct information to and from the central nervous system. The autonomic nervous system is the part of the nervous system concerned with the innervation of involuntary structures, such as the heart, smooth muscle, and glands within the body
An image depicting the peripheral nervous system can be seen below.. A neurone consists of a cell body (with a nucleus and cytoplasm), dendrites that carry electrical impulses to the cell, and a long axon that carries the impulses away from the cell
Neurotransmission: The Autonomic and Somatic Motor Nervous Systems [13]
The autonomic nervous system, also called the visceral, vegetative, or involuntary nervous system, is distributed widely throughout the body and regulates autonomic functions that occur without conscious control. In the periphery, it consists of nerves, ganglia, and plexuses that innervate the heart, blood vessels, glands, other visceral organs, and smooth muscle in various tissues.
The most distal synaptic junctions in the autonomic reflex arc occur in ganglia that are entirely outside the cerebrospinal axis. These ganglia are small but complex structures that contain axodendritic synapses between preganglionic and postganglionic neurons
Many autonomic nerves form extensive peripheral plexuses, but such networks are absent from the somatic system. Whereas motor nerves to skeletal muscles are myelinated, postganglionic autonomic nerves generally are nonmyelinated
