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 are the components of the CNS and PNS quizlet?
- central nervous system (CNS) the brain and spinal cord. …
- peripheral nervous system (PSN) the nerves exiting the brain/spinal cord that serves sensory and motor functions for the rest of the body. …

- vertebral column.
What are the components of the CNS quizlet?
The central nervous system is that part of the nervous system that consists of the brain, brain stem, and spinal cord.
What are the main components of the peripheral nervous system?
- 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 three main components of the peripheral nervous system quizlet?
- motor, voluntary – pharynx swallowing; larynx phonation.
- motor, autonomic (parasympathetic) – to heart (slows heart rate), to abdominal organs – controls secretion and motility.
- sensory – from aortic baroreceptors and chemoreceptors.
- sensory, from GI tract.
How do the CNS and PNS work together?
The PNS and CNS work together to send information between the brain and the rest of the body. Nerves emerge from the CNS through the skull and vertebral column, using the PNS to carry information to the rest of the body. The PNS is made up of two divisions – sensory and motor.
What are the 6 main components of the peripheral nervous system?
ComponentsFunctions*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 two main 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 subdivisions of the PNS?
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.
What are the two components of the central nervous system Nasm?The CNS, central nervous system, is comprised of two things, the brain and the spinal cord.
Article first time published onWhat is PNS in nervous system?
The peripheral nervous system consists of the nerves that branch out from the brain and spinal cord. These nerves form the communication network between the CNS and the body parts. The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.
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 is the difference between CNS and 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.
Which of the following is not the component of the PNS?
brain is NOT a part of the peripheral nervous system. The brain, brain stem and spinal cord are all components of the central nervous system…
What is the main function of the PNS?
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 component of the nervous system is divided into the somatic and autonomic divisions?
The peripheral nervous system (PNS) is divided into the somatic nervous system and the autonomic nervous system.
Which part of the CNS is made up of the midbrain pons and medulla oblongata?
The brainstem consists of the medulla oblongata, pons, and midbrain.
What are the four 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 main components of the nervous system and explain its three main functions?
The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.
What are the two divisions of the skeletal system Nasm?
Division of the Skeletal System This is going to be divided into the axial and appendicular skeleton. The axial skeleton consists of the skull, rib cage, and the vertebral column. The appendicular skeleton is made of around 126 bones in total.
Which of the following consists of a series of irregularly shaped bones divided into five different categories depending on where they are located in the backbone?
The spine The vertebral column (also called the backbone, spine or spinal column) consists of a series of 33 irregularly shaped bones (during childhood), called vertebrae. These 33 bones are divided into five categories depending on where they are located in the vertebral column (Fig 2).
Which characteristic is exhibited by Type 1 muscle fibers Nasm?
Type I fibers produce less force and are slower to produce maximal tension (lower myosin ATPase activity) compared to type II fibers. But they are able to maintain longer-term contractions, key for stabilization and postural control (1,2). Remember: Small muscle fibers.
Is the radial nerve part of the CNS or PNS?
The radial nerve is part of the peripheral nervous system. The peripheral nervous system sends signals from your brain to your arms and fingers, lower limbs, skin and internal organs.
Which of the following is not a type of glia cell in the CNS?
Satellite cells are not a neuroglia of the CNS. Satellite cells support cell bodies of neurons in the peripheral nervous system.
What is the peripheral nervous system composed of quizlet?
The peripheral nervous system is composed of: The cranial and spinal nerves that travel to all parts of the body.
What are the basic divisions of the peripheral nervous system quizlet?
- The peripheral nervous system. has two major divisions: the somatic nervous system and the autonomic nervous system.
- somatic nervous system. …
- autonomic nervous system.
What do the CNS and PNS have in common?
Both central and peripheral nervous systems are the two components of the nervous system of vertebrates. Both nervous systems are involved in responding different environmental stimuli in the environment, maintaining the life. Both nervous systems comprise neurons with the same physiology.
Where is the CNS and PNS located?
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.
Is ganglia components of PNS?
The PNS consists of all nervous tissue outside of the brain and spinal cord. It includes the ganglia, nerves, and receptors, as they are found in various parts of the body.
Which of the following is not a part of CNS?
Neuronal cell body of a sensory afferent is not part of the central nervous system. Sensory afferent nerves are located in the peripheral…
Is an abundant inhibitory neurotransmitter in CNS?
The most abundant inhibitory neurotransmitter in the central nervous system, gamma-aminobutyric acid (GABA), exerts its main effects via a GABAA receptor that gates a chloride channel in the subsynaptic membrane.
