Question

Comparing the somatic nervous system with the autonomic nervous system, which of the following statements is true?
A. The Autonomic Nervous system produces involuntary movement in the Skeletal muscles.
B. Somatic Nervous system produces voluntary movement in the glands and smooth muscles.
C. Autonomic Nervous system produces voluntary movement in the Smooth Muscles and glands.
D. Autonomic nervous system produces involuntary movement in smooth muscle, viscera and glands.

Answer 1

The central nervous system (CNS) is in charge of the majority of bodily and mental activities. It is divided into two sections: the brain and the spinal cord. Both the brainstem and the spinal cord are in charge of involuntary functions. The brain allows for higher-order thinking and cognitive awareness, whereas the spinal cord allows for simple reflex responses. The brain has several regions that are responsible for various functions, but the spinal cord only has one.

Complete explanation:
Option A: Sensory and motor pathways exist in the somatic nervous system, whereas motor pathways exist primarily in the autonomic nervous system. Internal organs and glands are controlled by the autonomic nervous system, whereas muscles and movement are controlled by the somatic nervous system.
So, option A is incorrect.
Option B: The somatic nervous system's major job is to connect the central nervous system to the muscles of the body in order to govern voluntary movements and reflex arcs.
So, option B is incorrect.
Option C: Certain biological activities, such as blood pressure and respiratory rate, are regulated by the autonomic nervous system. Without a person's conscious effort, this system operates automatically (autonomously).
So, option C is incorrect.
Option D: Internal organs and glands are controlled by the autonomic nervous system, whereas muscles and movement are controlled by the somatic nervous system.
So, option D is correct.

Therefore, Option D is the correct answer.

Note:
The neural system is responsible for controlling voluntary actions in the body by sending impulses from the central nervous system to skeletal muscle cells. It is made up of somatic nerves. The autonomic nervous system is responsible for involuntary actions such as physiological function regulation. It's a self-regulating system that sends impulses from the central nervous system to smooth muscles and involuntary organs. The autonomic neural system is further subdivided into the following categories: Sympathetic nervous system and Parasympathetic nervous system.
