Which of the following are the two major parts of the nervous system quizlet?
The nervous system is divided into two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and the spinal cord; the peripheral nervous system consists of peripheral nerves, which are located throughout the rest of the body.
What are the two parts 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 divisions of the somatic nervous system?
- Spinal nerves: They are mixed nerves that carry sensory information into and motor commands out of the spinal cord.
- Cranial nerves: They are the nerve fibers that carry information into and out of the brain stem.
What are the 3 main parts of the nervous system?
- The brain and the spinal cord are the central nervous system.
- The nerves that go through the whole body make up the peripheral nervous system.
What are the two main functions of the somatic nervous system?
The somatic nervous system is part of the peripheral nervous system. Major functions of the somatic nervous system include voluntary movement of the muscles and organs and reflex movements. In the process of voluntary movement, sensory neurons carry impulses to the brain and the spinal cord.

What are the 3 main parts of the nervous system quizlet?
The main parts of the nervous system include the brain, spinal cord, and the peripheral nerves. You just studied 29 terms!
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.
Article first time published onWhat are the two branches of the somatic nervous system quizlet?
It contains two branches; sympathetic nervous system and parasympathetic nervous system.
What is divided into two distinct branches sympathetic and parasympathetic?
The autonomic nervous system regulates many of the internal organs through a balance of two aspects, or divisions. … 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 two types of cells found in nervous tissue?
Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
Which are the parts of autonomic nervous system?
The autonomic nervous system has three branches: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.
What are the somatic and autonomic nervous systems?
The somatic nervous system transmits sensory and motor signals to and from the central nervous system. The autonomic nervous system controls the function of our organs and glands, and can be divided into the sympathetic and parasympathetic divisions.
Which two are divisions of the sensory nervous system?
The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
What are the two types of cells that comprise nervous tissue quizlet?
Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses.
What are the parts of the nervous system quizlet?
- central nervous system. -Receives, processes, interprets, and stores incoming sensory information. …
- Brain. …
- Spinal cord. …
- Peripheral nervous system. …
- Somatic nervous system. …
- Autonomic nervous system. …
- Sympathetic nervous system. …
- Parasympathetic nervous system.
What are the main components of the central nervous system quizlet?
The central nervous system is that part of the nervous system that consists of the brain, brain stem, and spinal cord.
What is autonomic function?
The autonomic system is the part of the peripheral nervous system that is responsible for regulating involuntary body functions, such as heartbeat, blood flow, breathing, and digestion.
What 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.
What is difference between CNS and PNS?
The CNS consists of the brain and spinal cord, while the PNS includes all other nervous system tissue. All sensory receptors, sensory neurons and motor neurons are part of the PNS. The bones of the skull and spinal vertebrae encase all CNS neurons. … Groups of neurons form in both the CNS and the PNS.
What are the two branches of the autonomic nervous system and what are their effects on the body?
The sympathetic branch of the ANS is responsible for stimulating the fight or flight response. The parasympathetic branch has the opposite effect and helps regulate the body at rest. Autonomic disorders have many different causes.
What is a sympathetic nervous system?
sympathetic nervous system, division of the nervous system that functions to produce localized adjustments (such as sweating as a response to an increase in temperature) and reflex adjustments of the cardiovascular system.
Which are part of the peripheral nervous system 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 two physical parts of each component of the ANS?
Parasympathetic Nervous SystemSympathetic Nervous SystemTarget organsGlands and organs of head and neck, thoracic, abdominal, and pelvic organsArrector pilli muscle, sweat glands, skin, blood vessels, thoracic and abdominal and pelvic visceral organs
What are the two divisions of the autonomic nervous system quizlet?
The two major divisions of the autonomic nervous system are the sympathetic division and the parasympathetic divi- sion.
Which division of the nervous system is divided into two opposing systems that control smooth muscles and glands?
The autonomic nervous system (ANS) serves as the relay between the central nervous system (CNS) and the internal organs. It controls the lungs, the heart, smooth muscle, and exocrine and endocrine glands, largely without conscious control.
What cell types are not part of the nervous system?
Satellite cells. The satellite cells are the cell types that are not found in the central nervous system. There are four…
What are the parts of nervous tissue?
The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.
What kind of cell perform the main function of the nervous system?
Neurons are the primary type of cell that most anyone associates with the nervous system. They are responsible for the sensory, integrative, and motor functions of the nervous system. They are electrically active and release chemical signals to target cells.
