The brain is a complex part of the human anatomy. It serves many functions and consists billions of nerves that bridge millions of connections and signals called synapses. Our brain has different parts and each of these parts have different functions. Read on as we discuss about the brain anatomy diagram and the functions of each main parts.

Cranium – If you were to look on an illustration of a brain anatomy diagram, you’ll see that cranium appears to be the part of the brain which serves as the “protector.” Cranium is like a “case” that protects our brain from minor injuries. This is the portion of the skull that encloses the human brain. Cranium consists of many bones that are joined by sutures and is made of 21 bones.

Cerebellum – is the part of the human brain that controls our balance, muscle tone, motor movement, coordination and equilibrium. Cerebellum is located at the base of the human’s skull, above our brainstem and beneath and cortex and occipital lobes.

Spinal Cord – serves as the information tunnel that connects the body and our brain. It is the one that’s responsible for connecting messages from the human brain and its distribution to the other parts of our bodies. It is located within the spine, extending from the skull’s base to the second lumbar vertebra.

Dura Mater – the core function of dura mater is to surround, protect and support the spinal cord. Dura matter is the outermost of the other layers of meninges (three meninges are dura mater, pia mater and arachnoids) surrounding our spinal cord and brain.

Brain Stem – is the one that connects our spinal cord and our brain’s cerebrum. Brain stem has several important functions namely; digestion, alertness, arousal, breathing, blood pressure, heart rate and other automatic functions.

Basal Ganglia – is located on the base of the human’s fore brain. Basal ganglia are the ones responsible for our body’s voluntary movements. It transmits neurotransmitters to the other parts of our brain.

Cortex – (also known as cerebral cortex) constitutes the biggest portion of the human’s brain. It is the epicenter of our higher thoughts. This part of the brain anatomy diagram is responsible for our attentiveness, language, awareness and memory. Cortex has four lobes and each of them has different functions. The four lobes are the occipital, temporal, parietal and front lobes. Each of these parts is discuss below.

· Occipital Lobe – is the visual processing core of the brain. Occipital lobe, as discussed on the brain anatomy diagram above, is one the four main regions of our brain’s cerebral cortex. The two main function of occipital lobe are; color recognition and visual perception. Because the occipital lobe is located at back part of the human brain, it is not prone to injury.

· Temporal Lobe – the functions of temporal lobe are to retain visual memories; store new memories, comprehend languages, process sensory input and derive meaning.

· Parietal Lobe – is divided into two functional regions; one involves integrating visual sensory input and the other concerns perception and sensation. It is located above the occipital lobe and posterior to frontal lobe.

· Frontal Lobe – The core functions of the frontal lobes include; higher order functions, motor functions, planning and reasoning. The frontal lobe is located at the front most region of the brain’s cerebral cortex.
