Question: What is the primary difference between the somatic nervous system and the autonomic nervous system quizlet?

The somatic nervous system allows us to consciously control our skeletal muscles, and the autonomic 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.

What is the primary difference between the somatic nervous system and the autonomic nervous system?

The autonomic nervous system consists of two sub-components, whereas the somatic nervous system only has one. The somatic nervous system has sensory and motor pathways, whereas the autonomic nervous system only has motor pathways.

What is the difference between the somatic and autonomic nervous systems quizlet?

The ANS differs from the somatic nervous system in that it can stimulate or inhibit its effectors. … The effectors of the somatic nervous system are skeletal muscles, while the ANS innervates cardiac and smooth muscles and glands. Compare the somatic and autonomic nervous systems relative to efferent pathways.

What is the difference between the autonomic and peripheral nervous system?

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.

What is the primary function of the somatic nervous system?

The brain and spinal cord are responsible for processing and integrating the various sources of information to allow us to develop a response. Therefore the main function of the somatic nervous system is to connect the CNS with organs and striated muscle to perform our daily functions.

What is an example of somatic nervous system?

Examples of the Somatic Nervous System Response

Striated skeletal muscles under voluntary control receive signals to contract on the basis of stimuli relayed to the CNS. For instance, while walking in a tropical forest, you watch the forest floor for fallen twigs, insects or undergrowth.

Where is the somatic nervous system located?

The somatic nervous system consists of the cell bodies located in either the brainstem or the spinal cord.

Is Breathing somatic or autonomic?

Breathing Is Automatic and Not Autonomic

The control of breathing is an automatic process that works without conscious intervention when asleep, anesthetized, or awake and not specifically thinking about breathing.

What are two differences between somatic and autonomic reflexes?

The main difference between the somatic and autonomic systems is in what target tissues are effectors. Somatic responses are solely based on skeletal muscle contraction. The autonomic system, however, targets cardiac and smooth muscle, as well as glandular tissue.

What is the autonomic nervous system responsible for?

The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing. This system works automatically (autonomously), without a person’s conscious effort. Disorders of the autonomic nervous system can affect any body part or process.

What is the main difference between the central nervous system and the peripheral nervous system?

The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.

Who controls the autonomic nervous system?

The brain stem with pituitary and pineal glands: The medulla is a subregion of the brainstem and is a major control center for the autonomic nervous system. The hypothalamus acts to integrate autonomic functions and receives autonomic regulatory feedback from the limbic system to do so.

What are the 3 divisions of the autonomic nervous system?

The autonomic nervous system is divided into three parts: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

What are the 2 main parts of somatic nervous system?

Thus the somatic nervous system consists of two parts:

  • Spinal nerves: They are peripheral nerves that carry sensory information into and motor commands out of the spinal cord.
  • Cranial nerves: They are the nerve fibers that carry information into and out of the brain stem.

What are three functions of the somatic nervous system?

The somatic nervous system is part of the peripheral nervous system. Major functions of the somatic nervous system include voluntary movement of the muscles and organs and reflex movements. In the process of voluntary movement, sensory neurons carry impulses to the brain and the spinal cord.

What would happens if the somatic nervous system is damaged?

Impact of Damage to the SNS

Diseases that impact the peripheral nerve fibers of the somatic nervous system can cause what is known as peripheral neuropathy. 4 This leads to nerve damage that causes numbness, weakness, and pain, often in the hands and feet.
