What are the major divisions of the nervous system 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).

What are the functions of the nervous system’s main divisions quizlet?

The two main PNS divisions are the somatic nervous system (which enables voluntary control of the skeletal muscles) and the autonomic nervous system (which controls involuntary muscles and glands by means of its sympathetic and parasympathetic divisions). Neurons cluster into working networks.

  • sensory input. when sensory receptors monitor changes that occur both inside and outside of the body.
  • integration. when sensory information is interpreted and the appropriate response is taken.
  • motor output. response that is performed by effectors- muscles or glands.

What are the 3 basic functions of the nervous system?

The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.

  • Memory and learning. …
  • Voluntary control of movement.

What is the basic structure and function of the nervous system?

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.
