How many anatomical divisions does the nervous system have?
two subdivisions
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 5 divisions of the nervous system?

What are the divisions and functions of the nervous system?
The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
What are the anatomical features of the central nervous system?
Put simply, the CNS is the supreme command center of the body. The CNS consists of two organs which are continuous with each other; the brain and spinal cord. They are enveloped and protected by three layers of meninges, and encased within two bony structures; the skull and vertebral column, respectively.
What are the major anatomical divisions of the human brain quizlet?
Terms in this set (27) Identify the two anatomical divisions of the nervous system. the two anatomical divisions of the nervous system are the central nervous system(CNS), consisting of the brain and spinal cord, and the peripheral nervous system(PNS), consisting of all neural tissue outside the CNS.
What are the main divisions of the central nervous system?
The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).
What are the main divisions of the nervous system quizlet?
What are the main divisions of the nervous system? Central nervous system and peripheral nervous system.
What is the normal anatomy of the nervous system?
The central nervous system (CNS) is made up of the brain and spinal cord. The brain controls most body functions, including awareness, movements, sensations, thoughts, speech and memory. The spinal cord is connected to the brain at the brain stem and is covered by the vertebrae of the spine.
What are the major divisions of the nervous system what are their major functions quizlet?
The structures of the nervous system are described in terms of 2 principal divisions-the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS (brain and spinal cord) interprets incoming sensory information and issues instructions based on past experience.
What are the two main divisions of the peripheral nervous system?
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 four major components of the central nervous system?
The spinal cord is connected to a section of the brain called the brainstem and runs through the spinal canal. Cranial nerves exit the brainstem. Nerve roots exit the spinal cord to both sides of the body. The spinal cord carries signals (messages) back and forth between the brain and the peripheral nerves.
What are the two anatomical divisions of the nervous system quizlet?
the two anatomical divisions of the nervous system are the central nervous system(CNS), consisting of the brain and spinal cord, and the peripheral nervous system(PNS), consisting of all neural tissue outside the CNS.
