If you know how a control unit functions in a data center, then you probably can guess how the human brain functions. The brain is a vital organ that controls the overall functioning of the human body. There are several interesting facts about the brain that we don’t know about for example the human brain is the largest brain in all vertebrates when comparing a ratio of body size to brain size. It is estimated to weight 1.5 kg on average and makes up two percent of the human body weight. Did you also know that the female brain is slightly smaller than the male brain?
A study of the anatomy of the brain is another important lesson in biology which children are exposed to at different points in their learning careers. The brain has several parts that can be seen on a diagram of the brain. Some of the parts include the cerebrum, divided into two main parts. There is an outermost part of the cerebrum called the cerebral cortex consisting of four lobes. However, a generalized division of the brain includes a forebrain, midbrain and hindbrain.
Each part of the brain coordinates a specific activity; for example the temporal lobe handles sound and language while the occipital lobe handles vision.
This page features an interactive annotated diagram. Its flexibility will enable students to learn the different parts of the brain and become masters of it. This online worksheet on brain anatomy can be used to learn by children in 2nd, 3rd, 4th, 5th, 6th, and 7th grade.
The brain is divided into five main regions, each of which plays a specific role in controlling and coordinating the body's functions. These regions are:
The cerebrum: This is the largest part of the brain and is divided into two hemispheres (left and right). The cerebrum is responsible for controlling movement, processing sensory information (such as sight, sound, and touch), and coordinating voluntary actions. It also plays a role in higher brain functions such as thought, memory, and emotion.
The cerebellum: Located under the cerebrum, the cerebellum is responsible for coordinating voluntary movement and maintaining balance and posture.
The brainstem: This is the lower part of the brain and is responsible for controlling vital functions such as heart rate, blood pressure, and breathing. It also plays a role in relaying information between the brain and the rest of the body.
The thalamus: Located between the cerebrum and the brainstem, the thalamus is responsible for relaying sensory information to the appropriate areas of the cerebrum.
The hypothalamus: Located just below the thalamus, the hypothalamus is responsible for controlling various automatic functions of the body, such as body temperature, hunger, thirst, and fatigue. It also plays a role in regulating emotions and controlling the release of hormones.
