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 is the main component of peripheral nervous system?

The peripheral nervous system (PNS) has two components: the somatic nervous system and the autonomic nervous system. The PNS consists of all of the nerves that lie outside the brain and spinal cord.

What are the three components of peripheral nervous system?

Structure. The peripheral nervous system is divided into the somatic nervous system, and the autonomic nervous system. The somatic nervous system is under voluntary control, and transmits signals from the brain to end organs such as muscles.

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

The Nervous System is divided into two parts. What are they? 1) The CNS (Central Nervous System) and 2) The PNS (Peripheral Nervous System.

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 two divisions of the autonomic nervous system?

The autonomic nervous system comprises two antagonistic sets of nerves, the sympathetic and parasympathetic nervous systems.

What are the two components of the somatic nervous system?

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.

What are the two function of dendrites?

The functions of dendrites are to receive signals from other neurons, to process these signals, and to transfer the information to the soma of the neuron.

What are the four main divisions of the peripheral nervous system?

The peripheral nervous system is subdivided into nerves, the autonomic system, and the somatic system. The autonomic nervous system is further subdivided into the parasympathetic and sympathetic nervous systems. The enteric nervous system is an independent subsystem of the peripheral nervous system.

What are the major functions of the peripheral nervous system?

The PNS has three basic functions: (1) conveying motor commands to all voluntary striated muscles in the body; (2) carrying sensory information about the external world and the body to the brain and spinal cord (except visual information: the optic nerves, which convey information from the retina to the brain, are in …

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

The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system. The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities.

What is sympathetic and parasympathetic?

The autonomic nervous system comprises two parts- the sympathetic and parasympathetic nervous system. The sympathetic nervous system activates the fight or flight response during a threat or perceived danger, and the parasympathetic nervous system restores the body to a state of calm.

What are the 3 divisions of the autonomic nervous system?

The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

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

The PNS connects the CNS to the rest of the body. The primary function of the peripheral nervous system is to connect the brain and spinal cord to the rest of the body and the external environment. The peripheral nervous system transmits information to and from the CNS.
