Which is characteristic of the sympathetic division of the autonomic system?

The two divisions of the autonomic nervous system are the sympathetic division and the parasympathetic division. The sympathetic system is associated with the fight-or-flight response, and parasympathetic activity is referred to by the epithet of rest and digest. Homeostasis is the balance between the two systems.

What are the characteristics of the central nervous system?

The central nervous system is the body’s processing centre. The brain controls most of the functions of the body, including awareness, movement, thinking, speech, and the 5 senses of seeing, hearing, feeling, tasting and smelling. The spinal cord is an extension of the brain.

What is the function of 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 is the difference between the somatic and autonomic nervous systems?

The somatic nervous system has sensory and motor pathways, whereas the autonomic nervous system only has motor pathways. The autonomic nervous system controls internal organs and glands, while the somatic nervous system controls muscles and movement.

Which of the following statements regarding the autonomic nervous system is incorrect?

Answer and Explanation: The incorrect statement is D. Both sympathetic and parasympathetic nervous system involve two neurons that signal target organs.

Which of the following is not a function of the autonomic nervous system?

Answer and Explanation: Emptying the bladder, increasing heart rate, and gland secretion are among the functions of the autonomic nervous system (ANS). Reflexes of skeletal muscle on the other hand, are functions of the somatic nervous system.

What is nervous system parts and functions?

The brain and the spinal cord make up the central nervous system. The nervous system is the most complex and highly organized body system. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.

What are the characteristics of the nervous system parasympathetic?

The parasympathetic nervous system is responsible for the body’s rest and digestion response when the body is relaxed, resting, or feeding. It basically undoes the work of sympathetic division after a stressful situation. The parasympathetic nervous system decreases respiration and heart rate and increases digestion.

What are the main function of nervous tissue?

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.

What is the main function of the nervous system quizlet?

The primary function of the nervous system is to collect a multitude of sensory information; process, interpret, and integrate that information; and initiate appropriate responses throughout the body.

What are the 4 types of nervous system?

The PNS is broken into the somatic nervous system and the autonomic nervous system.
  • Somatic Nervous System. The somatic nervous system is made up of motor neurons and sensory neurons that help the body perform voluntary activities.
  • Autonomic Nervous System. …
  • Sympathetic Nervous System. …
  • Parasympathetic Nervous System.

What are the major components of the nervous system?

The human nervous system is made up of three basic parts: the central nervous system, the peripheral nervous system, and the autonomic nervous system.

What are the 3 main functions of the nervous system quizlet?

The three general functions of the nervous system—receiving information, deciding what to do, and acting on those decisions—are termed sensory, integrative, and motor.

What is the difference between the autonomic nervous system and the somatic nervous system?

The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities. The autonomic nervous system consists of nerves that connect the CNS to the visceral organs such as the heart, stomach, and intestines.

What are two main functions of the nervous system?

Your nervous system is your body’s command center. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).
