What does the somatic nervous system process?
The somatic nervous system controls voluntary movements, transmits and receives messages from the senses and is involved in reflex actions without the involvement of the CNS so the reflex can occur very quickly. They are also known to predict certain important life outcomes such as education and health.
What is the function of the somatic nervous system quizlet?
The main functions of the somatic nervous system is to carry sensory information from nerves to the central nervous system and also carry motor information from the central nervous system along motor neural pathways to muscles to control their activity.
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. They have an extremely long course as they do not synapse after they leave the CNS until they are at their termination in skeletal muscle. They consist of large diameter fibers and are ensheathed with myelin.
Is Breathing somatic or autonomic?
Breathing Is Automatic and Not Autonomic.
What is the main function of the peripheral nervous system?
Peripheral nerves reside outside your brain and spinal cord. They relay information between your brain and the rest of your body. The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.
What happens if the somatic nervous system is damaged?
Diseases of the Somatic Nervous System
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.
Does the somatic nervous system control breathing?
The ANS affects heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, micturition (urination), and sexual arousal. Whereas most of its actions are involuntary, some, such as breathing, work in tandem with the conscious mind.
What nervous system controls involuntary actions?
The autonomic system, a complex subset of the peripheral nervous system, controls involuntary activities, such as heart rate, temperature, and the smooth muscle activity of the vascular and digestive systems.
What neurotransmitter controls the somatic nervous system and how does it work?
The neurotransmitter that controls the somatic nervous system is acetylcholine. The somatic nervous system is the part of the motor nervous system that is voluntary. This part of the nervous system controls all of the actions we can consciously control through contraction of skeletal muscle.
What is the difference between the autonomic and somatic nervous system?
The somatic nervous system is associated with activities traditionally thought of as conscious or voluntary. … The autonomic nervous system controls our internal organs and glands and is generally considered to be outside the realm of voluntary control.
