Your question: What are the two structural divisions of the nervous system?

What are the two 2 structural components of the central nervous system?

The central nervous system consists of the brain and spinal cord.

What are the two main divisions of the nervous system quizlet?

The structures of the nervous system are described in terms of 2 principal divisions-the central nervous system (CNS) and the peripheral nervous system (PNS).

What are the structural divisions of the central nervous system?

The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).

What are the two major components of the peripheral nervous system?

The peripheral nervous system is divided into two main parts:

  • Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.
  • Somatic nervous system (SNS): Controls muscle movement and relays information from ears, eyes and skin to the central nervous system.

What are the divisions and functions of the central nervous system?

The nervous system can be functionally divided into 3 actions: sensation, integration, and response. The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses).

What are the 3 main divisions of the nervous system?

divisions of the nervous system

  • Central Nervous System.
  • Peripheral Nervous System.
  • Divisions of the Nervous System.
  • Brain Structures.

What are the two main divisions of the peripheral nervous system how do these systems relate to the three types of muscle?

The two main divisions are the Somatic Nervous System and Autonomic Nervous System. The Somatic Nervous System controls the skeletal muscle system as well as the external sensory. The autonomic nervous system controls involuntary muscle systems such as smooth muscle and cardiac muscle.

What are the structural components of the peripheral nervous system?

The PNS can be divided into two components: the somatic nervous system and the autonomic nervous system. The somatic nervous system (SNS) and the autonomic nervous system (ANS) are both part of the peripheral nervous system. The SNS controls voluntary actions such as walking.

Which of the following are divisions of the peripheral nervous system?

The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division. The afferent or sensory division transmits impulses from peripheral organs to the CNS.
