The brain is one of the most complex and important organs in the human body. It controls all the functions of the body, allows us to think, feel, and move, and enables us to experience and interact with the world around us.
Structure of the Brain
The brain is divided into several main parts:
Cerebrum: The largest part of the brain, responsible for voluntary actions, intelligence, and sensory processing.
Cerebellum: Located at the back of the brain, responsible for coordination, balance, and muscle control.
Brainstem: Connects the brain to the spinal cord and controls basic functions such as breathing, heart rate, and digestion.
Thalamus: Acts as a relay station for sensory information.
The Living Environment: Students understand that cells are the basic unit of life, that all life as we know it has evolved through genetic transfer and natural selection to create a great diversity of organisms, and that these organisms create interdependent webs through which matter and energy flow. Students understand similarities and differences between humans and other organisms and the interconnections of these interdependent webs.
Cells: Students describe how living things are made up of one or more cells and the ways cells help organisms meet their basic needs.
Give examples of organisms that consist of a single cell and organisms that are made of a collection of cells.
