There are 3 main parts of the brain include the cerebrum, cerebellum, and brain stem. The Cerebrum can also be divided into 4 lobes: frontal lobes, parietal lobes, temporal lobes, and occipital lobes. The brain stem consists of three major parts: Midbrain, Pons, and Medulla oblongata. Although each structure has a distinct function, they work together to control all functions of the body. Main Parts of the Brain and Their Functions. At a high level, the brain can be divided into the cerebrum, brainstem and cerebellum. Cerebrum. The cerebrum (front of brain) comprises gray matter (the cerebral cortex) and white matter at its center. The largest part of the brain, the cerebrum initiates and coordinates movement and regulates temperature. The cerebral cortex is the part of the brain that makes human beings unique. Functions that originate in the cerebral cortex include: Consciousness; Higher-order thinking; Imagination; Information processing; Language; Memory; Perception; Reasoning; Sensation; Voluntary physical action; The cerebral cortex is what we see when we look at the brain.
It is composed by midbrain, pons and medulla. Midbrain: The midbrain is located at the mouth of the brain stem and is made up of the tegmentum and the tectum. It controls functions like body The cerebrum, which forms the major portion of the brain, is divided into two major parts: the right and left cerebral hemispheres. The cerebrum is a term often used to describe the entire brain. A fissure or groove that separates the two hemispheres is called the great longitudinal fissure.

Each part of the ear serves a specific purpose in the task of detecting and interpreting sound. 4 The Outer Ear. Picture a satellite dish that collects radio waves. The outer ear is similar! The curved formation on the outside ( the pinna) helps funnel sound down the ear canal to the eardrum. 5 The Middle Ear. The middle ear transfers the Glutamate is the most abundant excitatory neurotransmitter released by nerve cells in your brain. It plays a major role in learning and memory. For your brain to function properly, glutamate needs to be present in the right concentration in the right places at the right time. Too much glutamate is associated with such diseases as Parkinson’s
The cerebellum (“little brain”) is a fist-sized portion of the brain located at the back of the head, below the temporal and occipital lobes and above the brainstem. Like the cerebral cortex, it has two hemispheres. The outer portion contains neurons, and the inner area communicates with the cerebral cortex. Glutamate is the most abundant excitatory neurotransmitter released by nerve cells in your brain. It plays a major role in learning and memory. For your brain to function properly, glutamate needs to be present in the right concentration in the right places at the right time. Too much glutamate is associated with such diseases as Parkinson’s This lesson describes the structure of a prokaryotic cell including the nucleoid, plasmid, 70S ribosomes and cell wall. The engaging PowerPoint and accompanying resources are part of the first lesson in a series of 2 lessons which have been designed to cover the details in specification point (b) in AS unit 1, topic 2 of the WJEC A-level Biology specification.
