What nervous systems make up 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.
What makes up 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). The spinal cord and its attached spinal nerves serve two important functions.
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. The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities.
What are the four main 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 makes up the peripheral nervous system and the central nervous system Be sure to include all of the subdivisions?
Summary. The brain and spinal cord make up the central nervous system. The peripheral nervous system is comprised of the somatic and autonomic nervous systems. The somatic nervous system transmits sensory and motor signals to and from the central nervous system.
Which parts make up the major components of the peripheral nervous system?
somatic nervous system
The peripheral nervous system (PNS) has two components: the somatic nervous system and the autonomic nervous system. The PNS consists of all of the nerves that lie outside the brain and spinal cord.
What are the 2 divisions of the peripheral nervous system?
What constitutes the central and peripheral nervous system How are the components of CNS protected?
The central nervous system is better protected than any other system or organ in the body. Its main line of defense is the bones of the skull and spinal column, which create a hard physical barrier to injury. A fluid-filled space below the bones, called the syrnix, provides shock absorbance.
What are the components of the peripheral nervous system and their functions?
The PNS can be divided into two components: the somatic nervous system and the autonomic nervous system. The somatic nervous system (SNS) and the autonomic nervous system (ANS) are both part of the peripheral nervous system. The SNS controls voluntary actions such as walking.
What makes up the peripheral nervous system of the body?
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.
Where does the peripheral nervous system relay information?
Peripheral nervous system: Your peripheral nervous system consists of many nerves that branch out from your CNS all over your body. This system relays information from your brain and spinal cord to your organs, arms, legs, fingers and toes. Your peripheral nervous system contains your:
What makes up the central nervous system ( CNS )?
your central nervous system, or CNS, which consists of the brain and spinal cord your peripheral nervous system, which consists of nerves that connect your CNS to the rest of your body Nerves are made up of cells called neurons. These carry messages from one part of the body to another.
How does the nervous system help the brain?
Your brain uses your nerves to send messages to the rest of your body. Each nerve has a protective outer layer called myelin. Myelin insulates the nerve and helps the messages get through. Peripheral nervous system: Your peripheral nervous system consists of many nerves that branch out from your CNS all over your body.
