What is the peripheral nervous system quizlet?

The peripheral nervous system is the entire network of nerves located outside the CNS. It extends to the top of the head, throughout the body to the tips of the fingers and toes and to all parts of the skin. o To carry information from the CNS to the body’s muscles, organs and glands.

What are the two main functions of the peripheral nervous system?

What are the two major functions of the PNS? It’s two major functions are to carry information from the sensory organs and internal organs to the CNS, and to convey information between the CNS and all other parts of the body outside the brain and spinal cord.

What are the functions of the two divisions of the peripheral nervous system?

The sensory division of the PNS carries sensory information from the body to the central nervous system. The motor division of the PNS carries nerve impulses from the central nervous system to muscles and glands throughout the body. The nerve impulses stimulate muscles to contract and glands to secrete hormones.

Which of the following is the best definition of the peripheral nervous system PNS )?

Which description best fits the Peripheral Nervous System (PNS)? ( ) Nerves that carry sensory messages to the CNS and motor commands to the muscles and glands. ( ) Consists of the brain and spinal cord, located on the peripheral aspect of the body.

How is the peripheral nervous system related to the central nervous system?

Afferent neurons carry impulses from sense organs to the brain, while efferent neurons carry impulses from the brain to the muscles. The peripheral nervous system (PNS) is the network of nerves that send information from all parts of the body to the brain and spinal cord, a group called the central nervous system (CNS).

Is the autonomic nervous system part of the nervous system?

It is these sensory neurons that allow us to take in sensory information and send it to the brain and spinal cord. The Autonomic Nervous System The autonomic system is the part of the peripheral nervous system that’s responsible for regulating involuntary body functions, such as blood flow, heartbeat, digestion, and breathing.

How does the sympathetic and parasympathetic nervous system work?

This system is further divided into two branches: The sympathetic system regulates the flight-or-fight response. This system prepares the body to expend energy and deal with potential threats in the environment. The parasympathetic system helps maintain normal body functions and conserve physical resources.

Which is part of the nervous system carries sensory information?

The somatic system is the part of the peripheral nervous system responsible for carrying sensory and motor information to and from the central nervous system.

What are the functions of the different parts of the peripheral nervous system?

Overview of the Peripheral Nervous System

Components Functions
*All the nerves in the body outside of the spinal cord and brain *Includes sensory cells, motor nerve cells, and somatic cells *Connects the central nervous system to the parts of the body *Relays information and responses *Controls body functions

What are the 4 main functions of the nervous system?

The four main functions of the nervous system are:

  • Control of body’s internal environment to maintain ‘homeostasis’ An example of this is the regulation of body temperature.
  • Programming of spinal cord reflexes. An example of this is the stretch reflex.
  • Memory and learning.
  • Voluntary control of movement.

What are two differences between the central and peripheral nervous system?

The main difference between central and peripheral nervous system is that the central nervous system receives sensory information and the processed information is sent into effector organs as the response whereas the peripheral nervous system is involved in sending information to the central nervous system and sending …

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

The peripheral nervous system itself is divided into two parts: the somatic nervous system and the autonomic nervous system.

What are the two types of peripheral nerves?

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 major organs of the peripheral nervous system?

The organs of the peripheral nervous system are the nerves and ganglia. Nerves are bundles of nerve fibers, much like muscles are bundles of muscle fibers. Cranial nerves and spinal nerves extend from the CNS to peripheral organs such as muscles and glands.

What are the two parts of nervous system?

The nervous system has two main parts:

  • The central nervous system is made up of the brain and spinal cord.
  • The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

What is the function of the peripheral nervous system?

The main function of the peripheral nervous system (PNS) is to connect the central nervous system (CNS) to the rest of the body, such as the organs, muscles and limbs. The PNS is made up of nerves and neurons that connect the nervous system to the various parts of the body, which allows the brain to communicate with all areas of the body.

What makes up the nervous system of the body?

The nervous system is a controlling system of the body and is composed of nerve cells. It is further classified into central nervous system and peripheral nervous system. The brain and spinal cord collectively form the central nervous system and the network of nerves found outside the brain and the spinal cord is the peripheral nervous system.

What are the 12 nerves of the peripheral nervous system?

The first set of peripheral nerves are the twelve cranial nerves: olfactory (CN I), optic (CN II), oculomotor (CN III), trochlear (CN IV), trigeminal (CN V1, CN V2, CN V3 ), abducens (CN VI), facial (CN VII), vestibulocochlear (CN VIII), glossopharyngeal (CN IX), vagus (CN X), spinal accessory (CN XI), and hypoglossal (CN XII) nerves.

How does the sympathetic and parasympathetic nervous system work?

This system is further divided into two branches: The sympathetic system regulates the flight-or-fight response. This system prepares the body to expend energy and deal with potential threats in the environment. The parasympathetic system helps maintain normal body functions and conserve physical resources.

What are the roles of the divisions of the peripheral nervous systems?

The sensory division of the PNS carries sensory information from the body to the central nervous system. The motor division of the PNS carries nerve impulses from the central nervous system to muscles and glands throughout the body. The nerve impulses stimulate muscles to contract and glands to secrete hormones.

What are two components of the peripheral nervous system?

The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.

What are the functions of the peripheral nervous system?

The main functions of the PNS are voluntary movements such as chewing food, walking, and facial expressions. The PNS also regulates autonomic functions such as breathing, heart rate, and digesting – the unconscious bodily behaviors.

What are the parts of the central nervous system?

The central and peripheral nervous systems. The nervous system is comprised of two major parts, or subdivisions, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord.

Which is part of the nervous system carries sensory information?

The somatic system is the part of the peripheral nervous system responsible for carrying sensory and motor information to and from the central nervous system.

Is the autonomic nervous system part of the nervous system?

It is these sensory neurons that allow us to take in sensory information and send it to the brain and spinal cord.
