What muscles does the somatic nervous system control?

Simply put, the somatic nervous system innervates skeletal muscle, whereas the ANS innervates glands, neurons of the gastrointestinal tract, and cardiac and smooth muscles of glandular tissue.

What actions do the somatic nervous system control?

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.

Which muscles are controlled by the somatic nervous system quizlet?

The somatic nervous system is voluntary and controls skeletal muscle; The autonomic (visceral) nervous system is involuntary and controls involuntary muscles (cardiac and smooth muscle) and glands.

Is smooth muscle controlled by somatic nervous system?

The efferent portion of the peripheral nervous system consists of the somatic nervous system and the autonomic nervous system. The autonomic nervous system controls the function of glands, smooth muscle, cardiac muscle, and the neurons of the GI tract.

IMPORTANT:  Which statement best describes the central nervous system?

What does the somatic nervous system govern?

In addition to regulating the voluntary movements of the body, the somatic nervous system is also responsible for a specific type of involuntary muscle responses known as reflexes, controlled by a neural pathway known as the reflex arc.

What are somatic muscles?

Muscle derived from mesodermal somites, including most skeletal muscle.

Which of the 3 muscle cell types is controlled by the somatic nervous system?

Simply put, the somatic nervous system innervates skeletal muscle, whereas the ANS innervates glands, neurons of the gastrointestinal tract, and cardiac and smooth muscles of glandular tissue.

Which actions are functions of the somatic nervous system quizlet?

-Responsible for coordinated skeletal muscle activity to produce movement. – voluntary and reflex control of skeletal muscle. -Has sensory (afferent) arm connects the brain and spinal cord to skeletal muscle through the alpha motor neuron.

What are the two components of the somatic nervous system quizlet?

-It is usually conceptualized as having two components: the brain, the spinal cord. The “command center”; controls functions, movements, sensations, and thoughts. You just studied 35 terms!

What is somatic nervous system quizlet?

The somatic nervous system (SoNS or voluntary nervous system) is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. … The sensory division is a part of peripheral nervous system, it runs from sensory organs to the CNS (brain and spinal cord).

Which nervous system controls muscles?

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.

IMPORTANT:  Frequent question: What is Alzheimer's disease in psychology?

Do somatic reflexes control skeletal muscle?

Categories of Reflexes

Reflexes can either be visceral or somatic. … In contrast, somatic reflexes involve unconscious skeletal muscle motor responses. In doing so, these reflexes utilize some of the same lower motor neurons (alpha motor neurons) used to control skeletal muscle during conscious movement.

Which muscles are not controlled by the autonomic nervous system?

Skeletal muscle is not controlled by the autonomic nervous system.

How do somatic motor signals control the contraction of skeletal muscles?

When a somatic motor neuron is activated, all of the muscle fibers it innervates respond to the neuron’s impulses by generating their own electrical signals that lead to contraction of the activated muscle fibers.

What are somatic reflexes?

Somatic reflexes involve sensory neurons that connect sensory receptors to the CNS and motor neurons that project back out to the skeletal muscles. Visceral reflexes that involve the thoracolumbar or craniosacral systems share similar connections.

Does the somatic nervous system control breathing?

Examples of body processes controlled by the ANS include heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, urination, and sexual arousal. The peripheral nervous system (PNS) is divided into the somatic nervous system and the autonomic nervous system.
