How does the autonomic nervous system differ from the somatic nervous system?
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 is the difference between autonomic and somatic?
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.
How do somatic neurons and autonomic neurons differ quizlet?
Somatic neurons control skeletal muscle, while autonomic neurons control smooth and cardiac muscle. Somatic neurons control their effectors directly, while autonomic neurons use a series of neurons. Somatic neurons are always excitatory, while autonomic neurons may be either excitatory or inhibitory.
How are the functions of the autonomic nervous system and the somatic nervous system different quizlet?
The somatic nervous system controls voluntary skeletal muscles. The autonomic nervous system controls the glands and the muscles of the internal organs.
What is autonomic and somatic nervous system?
Somatic Nervous System is the one that allows conscious (voluntary) control of skeletal muscles. Autonomic N. S. has the unconscious (involuntary) control of the body and it has 2 branches, the Sympathetic and Parasympathetic NS.
What differentiates an autonomic reflex from a somatic reflex?
What differentiates an autonomic reflex from a somatic reflex? … A key difference is that a visceral reflex arc has two neurons in its (autonomic) motor component, whereas the somatic reflex arc has a single (somatic) motor neuron.
What is similar about the autonomic and somatic nervous system?
Use nerve impulse
Use glucose as an energy source for the muscles that they control. Weaken Myocytes. They are both controlled by the CNS.
What is the difference between a somatic reflex and an autonomic reflex quizlet?
Somatic reflexes involve contraction of skeletal muscles. Autonomic reflexes regulate smooth muscle, cardiac muscle, and endocrine glands.
