Nervous System

The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body. It is responsible for coordinating the body's actions and responses to both internal and external stimuli. The nervous system can be divided into 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 responses. The brain is the control center of the nervous system and is responsible for functions such as thinking, memory, and emotion. The spinal cord serves as a pathway for transmitting information between the brain and the rest of the body.

Peripheral Nervous System (PNS)

The PNS consists of all the nerves outside of the CNS. It is responsible for transmitting sensory information from the body to the CNS and transmitting motor commands from the CNS to the muscles and glands. The PNS can be further divided into the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which controls involuntary functions such as heart rate and digestion.

PHYSICAL SCIENCE (NGSS)

Matter and Its Interactions

Students who demonstrate understanding can:

Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.

Energy

Students who demonstrate understanding can:

Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.

Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).
