Anatomy & Physiology Nervous #11

Question

Which branch of the nervous system is responsible for voluntary muscular movements with the skeletal muscles of the body?

Answers

  1. Central nervous system
    • Rationale:

      The CNS is the part of the nervous system that consists of the brain and the spinal cord. It is responsible for integrating sensory information and responding accordingly; however, it is not responsible for voluntary muscular movements with the skeletal muscles of the body

  2. Somatic nervous system
    • Rationale:

      The somatic nervous system, a branch of the peripheral nervous system, is responsible for voluntary muscular movements in conjunction with the skeletal muscles of the body.

  3. Sympathetic nervous system
    • Rationale:

      The sympathetic nervous system’s primary function is to stimulate the body’s fight-or-flight response.While it is constantly active to maintain homeostasis, it is not responsible for voluntary muscular movements with the skeletal muscles of the body.

  4. Parasympathetic nervous system
    • Rationale:

      The parasympathetic nervous system is responsible for stimulation of activities that occur when the body is at rest, especially after eating. These functions include defecation, digestion, lacrimation, salivation, sexual arousal, and urination.

Overview

The nervous system is a network of both nerve cells and fibers that transmit nerve impulses between the parts of the body.

Explanation

Learning Outcomes

The nervous system is divided into two primary branches, the central nervous system (CNS) and the peripheral nervous system (PNS). The PNS has two branches, the somatic nervous system and the autonomic nervous system. The somatic nervous system is responsible for voluntary muscular movements with the skeletal muscles of the body.
