What structures make up the CNS and PNS?

What structures make up the CNS and PNS?

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 structures make up the PNS quizlet?

The peripheral nervous system includes the cranial nerves (connected to brain innervate the head), spinal nerves (connected to spinal cord innervates the rest of the body), and ganglia (collections of neuron cell bodies in the PNS).

What are the 3 parts of the peripheral nervous system?

The Peripheral Nervous System (PNS)

• 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.

How will you differentiate the central nervous system CNS and the peripheral nervous system PNS?

The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.

What does the PNS consist of quizlet?

Peripheral nervous system (PNS) consists of nervous tissue found outside the brain and spinal cord, including nerves that exit the CNS and ganglia found throughout the body cavities.

What are the 2 structures of the peripheral nervous system?

The peripheral nervous system itself is divided into two parts: the somatic nervous system and the autonomic nervous system. Each of these components plays a critical role in how the peripheral nervous system operates.

Which structure consists of the medulla midbrain and pons?

Brain stem
Brain stem: The brainstem is located at the juncture of the cerebrum and the spinal column. It consists of the midbrain, medulla oblongata, and the pons.

Are neurons in the CNS or PNS?

It is in the CNS that all of the analysis of information takes place. The peripheral nervous system (PNS), which consists of the neurons and parts of neurons found outside of the CNS, includes sensory neurons and motor neurons.

Which of the following describes the structure and function of the peripheral nervous system?

The PNS consists of the nerves and ganglia outside the brain and spinal cord. The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body….External links.

What makes up the CNS and PNS quizlet?

Terms in this set (2) The CNS ontains the brain and spinal cord. The peripheral nervous system, or PNS, consists of the nerves and ganglia outside of the brain and the spinal cord.

Which parts make up the major components of the peripheral nervous system quizlet?

consists of afferent nerves, sensory cranial and spinal nerves that connect somatic receptors to the central nervous system (CNS), and efferent nerves, motor cranial and spinal nerves that connect the CNS to skeletal muscles.

What are CNS and PNS?

Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord.

What is the functional subdivisions of the PNS?

Peripheral Nervous System Divisions. In the remaining article, we will discuss the peripheral nervous system in terms of its subdivisions. Somatic Nervous System. It is a subdivision of the peripheral nervous system that is mainly responsible for carrying out motor activities of the body. Autonomic Nervous System. Physiology. Pathology. Summary.

What are the components of the CNS and PNS?

Central nervous system (CNS) consists of brain and spinal cord of the body. Peripheral nervous system (PNS) consists of dorsal and ventral root nerve cell heads, spinal and cranial nerves.

What does the PNS consist of?

The PNS consists of cranial nerves, spinal nerves, and billions of sensory and motor neurons. The primary function of the peripheral nervous system is to serve as a pathway of communication between the CNS and the rest of the body.

Are most Association neurons are confined within the PNS?

Association neurons are also known as interneurons. Most association neurons are confined within the peripheral nervous system (PNS). Most association neurons are multipolar. Association neurons account for over 99% of the neurons in the body.
