You asked: What is innervated by the somatic nervous system?

What does the somatic nerve fibers innervate?

The somatic nervous system consists of sensory nerves carrying afferent nerve fibers that relay sensation from the body to the central nervous system (CNS). The other nerves in the SNS are motor nerves carrying efferent nerve fibers that relay motor commands from the CNS to stimulate muscle contraction.

What does the somatic nervous system innervate quizlet?

consists of somatic motor neurons that innervate the skeletal muscles of the body. When a somatic motor neuron stimulates a skeletal muscle, it contracts; the effect is always excitation.

What does the somatic nervous system activate?

The primary function of the somatic nervous system is to connect the central nervous system to the body’s muscles to control voluntary movements and reflex arcs.

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 is the somatic nervous system made up of?

The somatic nervous system consists of both afferent (sensory) and efferent (motor) nerves [1]. It is also responsible for the reflex arc, which involves the use of interneurons to perform reflexive actions. Besides these, there are thousands of other association nerves in the body.

What is somatic response?

Explanation: The somatic nervous system is the nervous system responsible for voluntary control of muscles. … A motor response is when the muscle moves when prompted by the nervous system.

What are the autonomic and somatic nervous systems?

The somatic nervous system transmits sensory and motor signals to and from the central nervous system. The autonomic nervous system controls the function of our organs and glands, and can be divided into the sympathetic and parasympathetic divisions.

What role does the somatic nervous system play 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.

What is the main difference between the somatic and autonomic nervous system quizlet?

What is the main structural difference between the somatic and autonomic nervous systems? Motor neurons of the SNS directly control effectors, whereas motor neurons of the ANS do not directly control effectors.

Is somatic nervous system voluntary or involuntary?

The voluntary nervous system (somatic nervous system) controls all the things that we are aware of and can consciously influence, such as moving our arms, legs and other parts of the body.

What is an example of the somatic nervous system?

One common example is the knee reflex: hitting the patellar tendon just below the knee cap with a reflex hammer leads to an automatic contraction of the quadriceps – which results in the lower leg kicking out.

What is somatic motor neuron?

Somatic motor neurons innervate skeletal muscle targets and are responsible for transmission of motor impulses from the brain to the periphery. Differentiation includes the processes involved in commitment of a cell to a specific fate.
