Nervous System

The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body. It is composed of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).

Central Nervous System (CNS)

The CNS consists of the brain and spinal cord. It is responsible for processing and integrating information received from the body and coordinating the body's activities.

Peripheral Nervous System (PNS)

The PNS includes all the nerves outside the CNS. It is further divided into the somatic nervous system and the autonomic nervous system.

Somatic Nervous System

The somatic nervous system controls voluntary movements and transmits sensory information to the CNS.

Autonomic Nervous System

The autonomic nervous system regulates involuntary bodily functions such as heart rate, digestion, and respiratory rate. It is further divided into the sympathetic and parasympathetic nervous systems, which have opposing effects on the body's functions.

Neurons

Neurons are the basic functional units of the nervous system. They transmit signals in the form of electrical impulses and are made up of a cell body, dendrites, and an axon. Neurons communicate with each other at junctions called synapses.

Nature of Science

The Practice of Science - A: Scientific inquiry is a multifaceted activity; The processes of science include the formulation of scientifically investigable questions, construction of investigations into those questions, the collection of appropriate data, the evaluation of the meaning of those data, and the communication of this evaluation. B: The processes of science frequently do not correspond to the traditional portrayal of ''the scientific method.'' C: Scientific argumentation is a necessary part of scientific inquiry and plays an important role in the generation and validation of scientific knowledge. D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Not only does science require creativity in its methods and processes, but also in its questions and explanations.

Define a problem based on a specific body of knowledge, for example: biology, chemistry, physics, and earth/space science, and do the following:

Use tools to gather, analyze, and interpret data (this includes the use of measurement in metric and other systems, and also the generation and interpretation of graphical representations of data, including data tables and graphs)
