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 major divisions of the nervous system what are their major functions?
There are two major divisions of the nervous system: the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system is made up of the brain, the spinal cord, and the retina and controls essentially all the functions that keep you alive and allow you to experience life.
What are the functions of the nervous systems main division and what are the three main neurons?
The three types of neurons are: sensory, motor, and interneurons. Sensory neurons carry messages from the body’s tissues and sensory receptors inward to the CNS. Motor neurons carry instructions from the CNS to the body’s muscles. Interneurons are the mid way point between the sensory input and the motor output.
What are the 3 divisions of nervous system?
divisions of the nervous system
- Central Nervous System.
- Peripheral Nervous System.
- Divisions of the Nervous System.
- Brain Structures.
What are the major divisions and subdivisions of the 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 divisions of the nervous system and the general physiological roles of the nervous system include CNS and PNS SNS and ANS?
The anatomical divisions are the central and peripheral nervous systems. The CNS is the brain and spinal cord. The PNS is everything else and includes afferent and efferent branches with further subdivisions for somatic, visceral and autonomic function.
What are the 4 main parts of the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.
What are the 2 subdivisions of the peripheral nervous system?
The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.
